There has been in this country no comprehensive treatment of the species as a whole and in logical order with convenient keys, and as a result this highly interesting and varied group has been neglected by many who would otherwise enjoy their study. Lloyd, Morgan, and Peck have been the principal recent students of the Gasteromycetes and their publications are indispensable. Morgan included all the families except Hvsterangiaceae and Hymenogastraceae, which were nearly unknown in America at that time, and established several new genera. Lloyd was occupied with these plants for years and has published a large number of good photographs, several monographs, and many notes. His collections, which are the largest in America, are available, and so are Peck's, but so far as this group is concerned Morgan's, unfortunately, have been almost destroyed. In preparing this book we have studied all available species microscopically and have compared types and authentic specimens in many cases. To this end the senior author has visited the following herbaria: Persoon's at Leiden, Bresadola's at Stock- holm, Kew Herbarium, New York Botanical Garden Herbarium, Curtis Herbarium, Schweinitz Herbarium, Lloyd Herbarium, and the Pathological and Mycological Herbarium at Washington. This last contains Michener's herbarium which includes many important plants from the Schweinitz Herbarium. To a number of correspond- ents we are indebted for generous gifts of material. Among these are Dr. W. A. Murrill, Mr. C. G. Lloyd, Miss Edith Cash, Mr. John Dearness, Dr. Homer D. House, Mr. H. C. Beardslee, Dr. Roland Thaxter, Mr. F. W. Pennell, Miss E. M. Wakefield (Kew), Professor N. Patouillard (Paris), Dr. G. F. Weber, Dr. C. L. Shear, Mr. Elam Bar- tholomew and Mr. G. H. Cunningham (New Zealand). Other members of the botanical staff of this University have been of much assist- ance. Most of the microscopic work has been done by Dr. Couch and the drawings have been made by him and Miss Alma Holland, the latter having done all the ink work and drawn many of the spores. Nearly all the written matter and most of the photo- graphs are by the senior author and the microscopical work and drawings have been carefully supervised. The literature has been referred to throughout this work under families, genera and species, but for convenience we list on page 194 the more important general works dealing with the entire group or with several families. w. c. c. Chapel Hill, N. C. June, 1927. ARTIFICIAL KEY TO THE FAMILIES Plants emerging at maturity from a soft volva or "egg;" the spores bornein a slimy, brown, bad-smelling liquid at the top of a stalk or net or several columns Phallaceae (p. 3) Not as above Plants with a distinct firm or gelatinous stalk which carries the spore-bearing sac, the latter in our representatives having a distinct apical mouth through which the spores escape as a dry powder. Stalk firm and fibrous; mouth not red Tylostomataceae (p. 149) Stalk gelatinous; mouth red Calostomataceae (p. 185) Plants without a distinct, terete or gelatinous stalk; if a stalk is present it is thick and expands gradually into the swollen spore-bearing part above. Plants small, shaped like cups or tumblers or subspherical, at maturity opening in most of the species over the entire top by the collapse of a veil (or rarely by the crumbling of the peridium) to expose a number of small flattened peridioles with hard coats which contain the spores, the whole looking like a little nest containing eggs. Nidulariaceae (p. 173) Plants growing on wood; very small, spherical, exploding at maturity and throwing out to some distance a single minute peridiole Sphaerobolaceae (p. 146) Not as above Peridium without a distinct outer layer that falls away or splits; at maturity opening at the top by irregular lobes, or by an irregular tear, or by crumbling or rotting away. Elongated threads (capillitium) not present among the spores. Gleba not formed of hollow chambers, but of sterile plates cutting out irregular blocks which are stuffed with the fertile tissue; at maturity crumbling into a dusty powder Sclerodcrmataceae (p. 160) Gleba formed (at least when young) of hollow chambers which are lined with the hymenium. Peridium rotting away after maturity, the gleba (at least in species we are treat- ing) turning into a slimy or gelatinous mass. Tramal plates radiating from the base and not intimately onnected with the peridium Hysterangiaceae (p. 15) Tramal plates not radiating from the base and intimately connected with the peridium Hymenogaslraceae (p. 24) Peridium crumbling away after maturity, the glebal chambers remaining intact and falling apart as fine sand-like particles Arachniaceae (p. 144) Peridium without a distinct outer layer; at maturity opening ventrally by separating around the stem and expanding more or less; capillitium not present. Secoliaceae (p. 53) Peridium with a distinct outer coat (Calvatia rubro-flava is an exception) which falls away in flakes or wears away by degrees at maturity, or dehisces equatorially, or (in Ceaster) splits into star-like rays to expose the thin, pliable or (in Calvatia) fragile and brittle inner peridium; gleba composed of small, hollow chambers lined with the hymenium (obscure in Disciseda); spores mixed with a true capillitium of long, slender, branched or unbranched threads (broken up into short sections at maturity in Disciseda) and escaping as dust through a definite (except in Calvatia) pore or slit. (In several small species of Lycoperdon the outer peridium is very thin, obscure and persistent, and in Myriostoma there are several pores) Lycoperdaceac (p. 58) PHALLACEAE* Plants consisting at first of a white, elastic, oval or subspherical "egg," which consists of three coats, the central one soft and gelatinous, which break at maturity to allow the elongation and exposure of the curious, spongy, and in some species brightly colored receptaculum of various shapes which bears above either on itself or on a specialized appendage the slimy, deliquescing gleba which contains the spores, and which in nearly all cases has a very strong and offensive odor by which insects are attracted to scatter the spores. Basidia, so far as known, club-shaped (very peculiar in Anlhurus), with several (4-8) sessile (no mucro), smooth, minute, apical spores. The family is divided into two subfamilies or by some authors (as Corda and Fischer) into two distinct families which are separated by the position of the gleba and by other important microscopical characters. These subfamilies may be simply defined as follows : Gleba (and spore slime) borne on the inner side of the receptaculum Clathreae Gleba borne on the outer surface of the receptaculum Phalha? The unique genus Phallogaster , placed by Morgan, its author (1. c, 15: 171, pi. 11. 1892), and by Thaxter (Bot. Gaz. 18: 117, pi. 19. 1893) in the Phallaceae, but differing from them in the absence of a volva and in other ways, is treated by Fischer in the Hysterangiaceae (1. c, Pflanzenfamihen, p. 307), and we are following him in this. PkaUogasler, Protubera, and Protophallus mark a distinct advance toward the Phalloids and indicate their descent from the Hysterangiaceae. The last mentioned genus is, in fact, so Phalloid-like that it is placed by its author among them. It is distinctly intermediate between the two families and if put in the Phalloids, their family character- istics would have to be modified. As the number of our species of Phalloids is small, we key all of them under the family, and for the convenience of students we include all species described from the United States.

The receptaculum is a complete hollow sac bearing the hymenium on the entire inner surface. The spores are larger than in typical Phalloids and have a very distinct mucro. There is also no obvious slime. 4 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Conard. The Structure of Simblum sphaerocephalum. Mycologia 5: 264, pis. 96 and 97. 1913. Corda.

Receptaculum without a single distinct stem, but composed of an inflated hollow network or of several curved columns meeting and fused above; in all cases having the spore-bearing gleba attached to the inner side above as a slimy mass. Odor offensive. Only a few species are known and but two have been found in the eastern United States. For other species see Lloyd, Syn. Known Phalloids, p. 54. For literature see under the family. There is evidence that both of the following species are poisonous. Farlow reports the killing of hogs within twelve to fifteen hours by C. columnatus in North Carolina (Bot. Gaz. 15:45. 1890). Clathrus columnatus Bosc Laternea columnata Nees Plates 1 and 105 Eggs subspherical, about 2.5 cm. thick, bursting above into several flaps to allow the expansion of the receptacle which consists of 2-5 (in our plants 4-5) stout, spongy, curved and very delicate columns with separate, pointed, basal ends which remain in the volva, the distal ends incurved and completely fused into a flat roof from which hangs within the dark slimy mass of the spore-bearing gleba. Color of the receptacle rosy red, the base pale to colorless ; volva watery white, attached at base by a cord-like root. Odor about that of a stink horn, strong and fetid. Spores (of No. 4949) smooth, elliptic, minute, 1.8-2.4 x 3.7-4.8ju. This plant seems to be entirely southern in its range (but see Saccardo's Sylloge 7: 19) and confined to the sandy coastal plain of North Carolina southward. It was originally described from South Carolina and is also known from the Gulf states (see Long, Mycologia 9: 274. 1917). An interesting anomaly is shown by one of our plants (pi. 1). There is a natural perforation on one side at the top just about the center of one of the columns, exactly like the more numerous perforations in C. cancel- latus and in Simblum.

It differs from C. columnatus in the more globular receptaculum in the form of an open net-work. The color is red above, paler below; base surrounded by the conspicuous white volva with a central cord-like root. The dark, slimy, ill-smelling gleba containing the smooth, elongated spores is said to cover the entire inner surface of the thick, spongy elements of the net-work. Illustrations: Barla. Champ.

Fruiting bodies with a distinct hollow stalk which is seated in a smooth volva, the wall with or without chambers, dividing above into several elongated arms which are united at their tips and simple, or capped by a group of meshes like those of Simblum. Gleba borne within the arms or meshes, deliquescing into a dark slime. The original species (C. hirudinosus) and one other (C. Mulleri) are the only ones with a netted apex, the others have simple arms which taper up and are united at their tips only. Lloyd has separated the latter group as the genus Pseudocolus (Synopsis of the Known Phalloids, p. 51). Through C. Mulleri the genus approaches Clathrella. The species given below is the only one ever found in the northern hemisphere and is known only from the type locality. For literature see Fischer, Lloyd and Penzig as cited under the family. - 5 •* 2 o < Pi rfi P Z H THALLACEAE ' Colus Schellenbergiae Sumstine This species has been collected but once, and this is the only record of a Colus in the northern hemisphere. We copy below the original description (Mycologia 8: 183. 1916): "Volva dark-brown, smooth, globose, 2-3 cm. in diameter, breaking at maturity into several irregular segments; receptaculum stipitate, the stipitate portion cylindric, hollow, reticulate-pitted, white below, orange-colored above, slightly enlarged upward, dividing into three arms; arms arched outward, united at the apex, transversely wrinkled, cylindric or sometimes compressed so as to appear triquetrous, orange- colored, attenuate upward, 3-6 cm. long; gleba dark green, borne on the inner side of the arms, foetid; spores hyaline, ellipsoid-ovoid, 4.5-5.5 x 2-2.5^." The species is near C.javanicus (See Penzig, 1. c, p. 160) and may be the same, as no important differences appear from the descriptions. Colus Garciae Miiller from Brazil has much the same appearance, but differs principally in the absence of chambers in the wall of the stem, a remarkable peculiarity for a Phalloid. Pennsylvania.

SIMBLUM Klotzsch Receptaculum formed of a distinct, hollow, delicate stalk which is transformed above into a somewhat larger inflated network which bears the gleba slime on the inside. Yolva watery white; receptaculum bright colored, red (in our species) or yellow, rarely whitish; odor offensive. Only a few species are known and only two are North American. For literature see under the family. Simblum sphserocephalum Schlecht Simblum rubescens Gerard 5. rubescens var. Kansensis Cragin Plates 2, 3 and 105 Stalk long, club-shaped, hollow, spongy, tapering downward to a narrow attach- ment in the bottom of the large, white, toughish, inflated volva; terminated above by the subglobose structure of thick, anastomosing strands that holds the dark slime con- taining the spores. Color bright red above, fading to pale below; odor strong and re- pulsive. The entire plant is about 7-9 cm. high and the stalk about 1-1.6 cm. thick above, its honeycombed wall 3-4 mm. thick near the top and only 1 mm. thick below. Spores (of No. 1427) elliptic, smooth, 1.4-2 x 3.7-4.4/*. This is a rare plant in the United States and has not been reported before from North Carolina (for distribution see Lloyd's Myc. Notes, p. 220. 1905). It is said to be common in South America. The only other North American species is S. texense which differs from the present one in its yellow color and longer spores, which are 3 x 7M (see Long, 1. c, p. 112, pi. 106, fig. 11). 8 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Our plate 3 shows an abnormal variation of two plants springing from one volva and fused at their tips. This is apparently of not rare occurrence as a similar example is shown in Lloyd's Myc. Notes No. 24, fig. 133, from a photograph of a Brazilian plant by Rick, and another such is illustrated by Gerard in his plate 2 (as cited below). Illustrations: Gerard. Bull. Torr. Bot.

Phalloids with a hollow, spongy, subcylindrical stem springing from a volva and bearing at the top several spongy arms which in youth embrace the dark gleba which covers their inner faces and sides; at maturity either remaining connivent at the tips or bending more or less strongly outward. There is a difference of opinion as to the correct definition of the genera Lysurus and Anthnrus. As originally described, in Lysurus the gleba is borne on the outside faces of the arms, while in Anthurus the gleba is described as enclosed within the arms in youth and covering their inner and side faces at full maturity, a dorsal zone remaining bare. We are following Burt and Fischer (Phalloideen, part 3, p. 41) in including our species in Anthurus. Lloyd (Syn. Known Phalloids, p. 35) and Rea (Trans. Brit. Myc. Soc. 2: 57. 1904) would put the species in Lysurus, modifying that genus to include certain species with the gleba on the inner surfaces of the arms. The genus Anthurus is described by Kalchbrenner (Grevillea 9: 2. 1880) as having the stem conspicuously flaring at the top and passing into several broadly spread- ing arms which bear the spore slime on the inner surface. The description does not state that the arms pass directly into the stem without a groove or abrupt change of texture, but the original figure of the type species (A. Mullerianus) has this appearance, and Fischer's figures of the same species are in agreement. Anthurus aseroeformis, a better known plant, is said to have this structure. Lloyd thinks these two species may be the same (Myc. Notes, p. 408, fig. 244). In the eastern United States there is but one representative, and that is found in the northern and central sections. There may be another American species, as a name (Lysurus Texensis Ellis) has been referred to without description (Bull. Torr. Bot. Club 7: 30. 1880), and Lloyd mentions a red Lysurus in Texas seen by Prof. Long (Syn. Known Phalloids, p. 40; also Myc. Notes, p. 407). In Mycological Notes, pp. 586 and 647, Lloyd reports L. Mokusin from hothouses at Chico, California, where it was probably introduced from the Orient. Anthurus borealis Burt We take the following description from Burt (Mem. Boston Soc. Nat. Hist. 3: 504. 1894) : "Solitary or subcaespitose. Stipe white, clavate, divided above into 6 erect, narrowly lanceolate, hollow arms incurved above, and with pale, flesh-colored backs < o PLATE 3 SlSIBUM SPHAEROCEPHALUM. No. 1426 PHALLACEAE 9 which are traversed their entire length by a shallow furrow having its surface con- tinuous with the surface of the stipe; cavity of the stipe nearly closed at the base of the arms by a thin diaphragm opening above into a closed chamber with dome-shaped wall even on its inner surface and adherent to the arms for about one-sixth their length; gleba brownish olive-green, supported upon the dome and closely embraced by the arms; spores simple, olive-green, ellipsoidal, 3-4 x 1.5/x, 5-8 on septate and constricted basidia. "Total height of plant 10-12 cm. ; arms one-sixth of this; greatest diameter of stipe 15 cm." As Lloyd supposes, this species is almost certainly introduced from the tropics or south temperate regions. The basidia as described by Burt are most remarkable. They are constricted at intervals so as to appear like a row of beads, a form apparently unknown in other Basidiomycetes. Individual plants vary greatly in size: in those we have seen, the arms in the dry state varying from 1 to 3.6 cm. in length. In addition to plants seen which are cited below, the species has been reported from Ohio, Connecticut, Mas- sachusetts, England and Germany. (See Lloyd, Myc. Notes, pp. 183, 219, 386, 515; Beardslee, Ann. Rept. Ohio St. Acad. Sci. 9: 19. 1901; Sumstine, Ohio Naturalist 6: 474. 1906; Stockberger, Ohio Naturalist 6: 517.) Lloyd thinks it very probable that L. anstraliensis (see figure by Rea in Trans. Brit. Myc. Soc. 2: pi. 3, fig. A. 1904), L. Clarazianus and L. Gardneri are all the present species (Myc. Notes, p. 594).

Burt considers the two species the same (1. c, p. 344). Lloyd's interpretation would probably refer the left hand plant on our pi. 4 to M. caninus, the two right hand plants to M. Ravenelii.

Nigropogon asterosporus n. sp. Plate 108 Fruit body hypogeal, subglobose, 11 mm. thick when fresh, shrivelling and drying to a little more than half its original size ; peridium when fresh nearly pure white, drying tawny or amber brown; rooting by an entangled network of very delicate black, hairlike fibrils; adherent, vein-like fibrils entirely lacking on the surface. Peridium 100-220ju thick, of one layer composed of large parenchymatous cells and delicate threads. Gleba pure white at first but soon becoming pale vinaceous russet or pecan brown (Ridgw.) as the spores are formed, drying sayal brown. Cavities up to 1.5 mm. wide by 120/i deep, sinuous, remaining empty. Tramal plates quite variable in thickness, 80-200m thick, usually about 1 10m thick, composed of thin-walled pseudoparenchymatous cells and threads, continuous with the peridium. Hymenium composed of short, more or less rectangular cells which elongate to form basidia. Basidia collapsing in the distal half immediately after the spores are formed, the proximal half persisting; 7.5-°m thick in the proximal half, 5.5-6.5m in the distal half by 26-38m long; usually with 4 (rarely 2) nearly sessile spores. Odor when fresh slightly like an old Irish potato but not unpleasant ; on drying becoming like that of ham, faintly nitrous or phosphorous. Spores color of gleba, very peculiar in shape, strongly angular, usually with four angles showing in optical section, the most acute angle being at the mucro end, 8.3- 9.8x11.5-12/*. This remarkable species belongs in the Hymenogastraceae, close to PJiizopogon. It is clearly distinct from that genus, however, in peridial and tramal plate structure and in the shape of the spores. In the present species the peridium and tramal plates are composed of pseudoparenchymatous cells and a few threads, while in PJiizopogon the peridium and tramal plates are composed of threads which usually are rather delicate; also the spores of this plant are angular while the spores of PJiizopogon are invariably elliptic and smooth. The rhizomorphs, the empty glebal chambers, and the structure and development of the basidia suggest a close relationship to PJiizopogon. The development of the basidia in this species is very peculiar. The hyrreniumis 38 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA composed of cells which are almost as thick as they are long. These cells elongate at the distal end to form a narrower tube and on the end of this tube the spores are borne. Since there is no cross wall between the cell and the tube and since both empty their entire contents into the spores, both together must be considered the basidium. After the spores are formed the tube collapses. A somewhat similar condition has been found and is described here for certain species of Rhizopogon and Odaviana purpurea. 8271. Under deep layer of decaying oak and dogwood leaves, slightly buried in the soil, Oct. 22, 1927. MELANOGASTER Corda Fruiting bodies rounded or irregularly lobed with branched fibrils springing from any part of their surface. Peridium tough, fleshy, not readily separable from the gleba. Gleba with rounded to polygonal chambers which are larger towards the center and become nearly or completely filled with spores. Tramal plates directly continuous with the peridium, bearing the numerous basidia which are not arranged in a definite hymenial layer but are irregularly distributed throughout a broad periph- eral zone which may nearly fill the cavity. Basidia club-shaped, 2-8-spored; spores usually apical on the basidia but not rarely somewhat laterally placed, elliptic, smooth, furnished with a cup at the proximal end. At maturity the gleba breaks down into a slimy mass and escapes by the final rupture of the peridium. The irregularly distributed basidia and the nearly solid interior at maturity gives this genus a superficial approach towards Scleroderma. The essential structure is, however, quite different as the chambers are not really stuffed solidly at all stages and the basidia are not surrounded by a ground tissue which nourishes and matures the spores. The distribution of the spores in a slime and not a powder is also a fundamental difference. Rhizopogon seems the nearest relative. We are including four species, two from New York State and two from North Carolina. Key to the Species Spores less than 11m long and the distal end not pointed Peridium 300-600^ thick, composed of irregularly swollen hyphae 7.4-33m thick Odor strong and nauseous: basidia long, club-shaped M. nauseosus (p. 39) Odor not strong; basidia short and thick M. rubescens (?)

M. mollis Lloyd Plate 109 Part of a collection of this plant preserved in formalin was sent us by Dr. Fitz- patrick from Cornell University. From this collection the following descriptive notes have been made: Fruiting bodies up to 3.7 cm. in diameter, irregular in form; attached at base by elaborately branched rhizomorphs. Peridium simple, composed of closely packed, much entangled, clamp-connected threads, 3-7/* thick; surface of peridium covered with numerous, thick-walled, swollen, club-shaped cells; peridium deep brown in section, quite variable in thickness, 50-300/i thick. Tramal plates directly continuous with ts Pi HYMENOGASTRACEAE 39 the peridium, concolorous with it in places but usually appearing white (?) to the naked eye or hyaline under the microscope; 74-148/* thick. Threads of the tramal plates 2-6m thick, separate, considerably branched and much entangled, highly gelatinizable. Glebal chambers quite variable in size, 0.3-2 mm. long, elongated or polygonal basidia irregularly disposed. Spores black in mass, dark brown under microscope, 3.5^1 x 7-10. 4/u, elliptic, smooth, with a distinct hyaline cup (the remains of the short stalk which attached the spore to the basidium) at the proximal end. Basidia irregularly arranged, 4.2-5 x 12-18p, club-shaped, usually with four spores, rarely with three or only two. The spores of the present plant have been compared with type material kindly sent us by Dr. Dodge from the Sprague Herbarium at Cambridge. The spore sizes of the type vary from 3.7-4.5 x 7-9/j, rarely 10,u long, and have rather indistinct prongs (rings) at the proximal end. The spores of the present plant, while agreeing with the type in size, differ from the latter in having the proximal end extended into a rather long and fairly conspicuous cup-like stalk. These cup-like extensions while present on the proxi- mal end of the type spores are much less conspicuous than in the present plant. The threads composing the tramal plates and peridium of the type material are so collapsed that it is very difficult to make out their structure. The present plant agrees with material kindly given us by the New York Botanical Garden which was collected and identified by Dr. Hollos in Hungary (Krypt. Exs. No. 1812) except that the spores of the latter plant are slightly thicker and without such a distinct stalk. The slight differences in spore size and structure do not seem sufficient to exclude the present plant from M. variegatus. The present species is distinct from the Blowing Rock plant No. 5804, described below, in size, in peridial structure and in spore color and size. Illustrations: Bucholtz. Beitr.

Plates 27 and 108 Fruiting bodies gregarious, subglobose; up to 3 cm. wide by 2 cm. high, most about 2 cm. wide by 1 .5 cm. high. Peridium light cinnamon brown when fresh, becoming darker, about russet; outer part turning reddish upon being cut or bruised or eaten by insects. Fibrils rather large below, few and very inconspicuous above, darker than the peridium. Peridium, 300-600/j thick, single; composed of large, subglobose to elon- gated vesicular cells usually about 20/i thick, often up to 33 x46/i; on the outer side are occasional patches of septate irregular threads with clamp connections. Gleba at first white, then becoming light tan and auburn as the spores mature and finally black in the dried plants, except for the yellowish tramal plates; more or less firm and solid when fresh and young, but changing upon maturing into a slimy gelatinized mass. Glebal chambers 1-3 mm. wide, polygonally shaped, loosely filled from the first with hyaline hyphae. In these are developed one to several "pockets" of spores. Chambers without a distinct hymenial layer, basidia irregularly disposed. Basidia elongated, club-shaped, 4.6-5.8/t thick, with 4-8, usually 6 or 7, nearly sessile spores. Basidia 40 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA gelatinizing and early disappearing. Odor very strong, penetrating and peculiar, quite unpleasant, nauseous, but with a somewhat fruity element like decaying apples and very attractive to fruit flies, even in the dried condition. Spores smooth, elliptic, 3.9-4.2 x 7.4-8.4ju, with a hyaline cup at the proximal end. This species seems close to M . variegatus in certain characters, but it can be easily distinguished in the fresh condition by the very striking and unpleasant odor. In M . variegatus the spores are 2-5 on a basidium and are larger than in the present species. The shape of the basidia is also quite distinct as shown by Tulasne's figures. The name of M. odoratissimus suggests this plant but the odor of that is described as pleasant while the odor of this is decidedly otherwise; the basidia of that plant are short and distinctly swollen at the distal end, and the spores have a distinct long stalk (Hesse). The most important characters in distinguishing the present plant are the brownish colored peridium which becomes red on being wounded, the large vesicular cells of the peridium, and the exceedingly strong unpleasant odor. This species is nearest the plant treated tentatively as M. rubescens, but careful comparison shows them to be distinct. In section the dried gleba appears much alike in the two plants except that in the Chapel Hill plant the tramal plates are much more distinct. Sections, however, when soaked in water so that they regain approximately the size when fresh show striking differences: in the Blowing Rock plant the "cavities" are invariably stuffed with spores and the tramal plates are thin and rather inconspicu- ous, while in the Chapel Hill plant the cavities are only partially filled, leaving the plates broad and conspicuous. The structure of the tramal plates at maturity is quite different: in the plant from Blowing Rock they are composed of entangled hyphae which are partly gelatinized and which do not break apart easily when crushed; in M. nauseosus they are composed of highly gelatinized hyphae which break apart when crushed into separate units much like the cells in the subhymenial layer in Crucibulum. Furthermore the spores in M. nauseosus are slightly larger and the basidia of the two plants are quite different in shape. 8281. On and under beech leaves and humus, Nov. 4, 1927. ? Melanogaster rubescens (Vitt.) Tul. Plate 109 During the summer of 1922 we collected in the mountains a single specimen of this interesting plant. Unfortunately no notes were made on the fresh state. Our plant in the dried condition is decidedly shrunken, subglobose, 11 mm. thick; surface dark bay-brown, finely rivulose as if wrinkled in drying and marked on the lower half by a few inconspicuous veins. Peridium simple, 320-450^ thick, composed of irregularly swollen hyphae about 7.4-25/j thick and nearly hyaline under the microscope. Gleba very hard, black and solid, with no cavities; when cut showing a shining surface with faint whitish lines of the tramal plates outlining very large areas up to 1.5 mm. wide, which are not sinuous, but box-shaped like parenchyma cells. These chambers are solidly filled with the hard, black spore-mass, a condition different from species we are referring to Rhizopogon. Tramal plates 35-1 10^ thick. Spores smooth, black in mass, light brown under the microscope, subelliptic, 3.4-4.2 x 5.5-8.8^, the more mature ones showing the pale cup-like base as in M. variegatus. Basidia short and thick, 7-9 x 12— 15yu, 4-8-spored, the sterigmata short. PLATE 26 Rhizopogon truncatus. Type [above] Calvatia elata. No. 2S43H [below] HYMENOGASTRACEAE 41 Zellcr and Dodge have referred to Rhizopogon several species in which the glebal chambers are solidly tilled with black contents at maturity. Of these R. pachyphloeus seems nearest our plant, and Dodge seems inclined to put it provisionally in thatspecies. To us, however, it differs strikingly in the far greater development of superficial fibers, its much thicker peridium, thinner tramal plates and very much smaller glebal cham- bers. From R. diplophlocus, also with solid contents, our plant differs in the simple peridium, larger glebal cells, smaller basidia and larger spores. We think the plant is best treated as a Melanogaster, but with only one plant and no notes on the fresh con- dition, we think the specific name somewhat doubtful. After referring to M. variegatus, Dr. Dodge in a letter says, "There is much closer resemblance between your material and Melanogaster rubescens (Vitt.) as interpreted by M. A. Curtis. He so determined (Ms. note in his copy of Schweinitz, specimen from Schweinitz Herb, in Curtis Herb.) material collected by Schweinitz and referred by Schweinitz to Rhizopogon acstivus Wulfen ex Fries.* The peridium of the Schweinitzian specimen is about \ the thickness of your No. 5804 but it has a somewhat collapsed appearance as do many of the older specimens which were repeatedly poisoned by the old methods. The spores are much the same but darker than in your specimen. I have never seen any authentic material of this species, so do not know whether Curtis's interpretation is correct or not. Apparently Peters got the same thing in Alabama. Your material has much lighter spores than anything I have ever seen in Melanogaster, but I am not quite sure whether that is significant as in some other groups spores do not assume their full color until late. For the present I am inclined to leave the specimen in RJiizopogon pachyphloeus Z. & D. until I have had further opportunity to study Melanogaster." The relationship to M. rubescens is indicated by the basidia, which are similar to those shown in Tulasne's figure, and by the appearance of the peridium. Blowing Rock. Coker and party, No. 5804. Exposed on humus under chestnut and rhododendron, August 26, 1922. Melanogaster ambiguus Tul. Plate 109 Dr. L. H. Pennington has kindly sent us a section of a plant found by him in New York and reported by Lloyd as M. ambiguus (Myc. Notes, p. 1065, fig. 2005). The dried section of the plant is slightly over a centimeter thick and has a con- siderably wrinkled blackish bay peridium. In section the peridium is simple; about 300/i thick in dried condition and about 600ju thick when fresh (from prepared slide of Pennington); composed of very irregularly interwoven threads with numerous bladder-like swellings. Gleba jet black, the chambers rounded and filled with spores, 0.5-2 mm. wide; tramal plates very narrow, cream colored, contrasting strikingly with the black spore mass. Spores 7.7-10.4 x 13-18^, most about 8.5 x 15.9/j, broad-elliptic, more or less pointed at both ends, with a distinct cup-like prolongation at the proximal end, deep brown in color under the microscope. Basidia 8.5-11.8 x 22-26/z, club-shaped, with 2-4 sessile spores; cavities filled with interwoven threads, 3-3. 7/j thick, which give rise here and there to basidia. • Probably not in the sense of modern authors who use this name as an older name of Rhizopogon rubcuens Tul. 42 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA "Odor strong and penetrating, somewhat like that of onions" (Pennington).

Our plants are larger on the general average than the size given by Zeller and Dodge, 6 mm. being their only measurement, while ours are from 5-17 mm. thick. Their single measurement, how- ever, comes within our range. In the color and the gross and minute structure of the peridium the plants also agree. In the thickness and color of the tramal plates and the size of the basidia and spores the plants are distinct. Zeller and Dodge give the tramal plates as 40-50/* thick between hymenia while ours are 70-150/* thick, averaging about 100/* thick. In both plants the tramal plates are composed of three layers not including the hymenium. In L. araneosus the middle of these three layers is light brown while in our species it is white. The tramal plates in our plants are often scissile. The basidia of L. araneosus are 6-8/* x 8-10/*; ours are 8.2-9.4/* thick and apparently without a basal septum. The spores of L. araneosus are globose, 8-11/* in diameter; while those of the present species are subglobose, rarely globose, 8.5-11 x 11-14/*. Dr. Dodge has compared a specimen of our plant with his and thinks that there is no question but that our species is new. 8262. Under deciduous leaves and earth, upper Laurel Hill, Oct. 19, 1927.

Subterranean or partly exposed; peridium without superficial veins, not easily removable, in our species white or nearly so; glebal chambers empty at first, sometimes stuffed at maturity; spores oval, lemon-shaped or elliptic, in most cases pointed at the distal end and rough, in some species rounded at the distal end and smooth, but inclosed in a hyaline sac. The spores seem to be the only generic character of any value and they are of two distinct types (if descriptions can be trusted). Except for H. anomalus Pk., which Zeller and Dodge have transferred to Lenco- gaster, only one species has been reported from the eastern United States. This was determined by Lloyd as H. decorus, but we are transferring it to H. Thwailesii. We are herewith adding one other. Key to the Species Odor very strong, not pleasant; spores 6.5-7.4 x 10-13/i, surrounded by a sac H. foctidus Odor slight; spores 13-15 x 24-28/1 E, Thwailesii Hymenogaster foetidus n. sp. Plates 17, 18 and 110 Plants partly or entirely buried in soil under humus, single or cespitose or often fused, 0.3-1.3 cm. wide by 0.3-0.7 cm. high, when fresh, shrinking to about two-thirds this size on drying, rooting by several basal rhizomorphic strands; subspherical or lobed, fleshy, odor when fresh very strong and persistent, not pleasant, to some sug- gesting aniline oil, to others witch hazel. Peridium 0.5-0.8 mm. thick, simple but often partly covered with white byssoid mycelium, whitish when fresh, changing to creamy buff on drying, not changing color when cut or wounded; tender and fragile when fresh, becoming only slightly toughish on drying; smooth and without ridges or fibrils, but often encrusted with sandy particles, becoming wrinkled on drying ; composed of much entangled, densely packed, thin- and thick-walled threads, the latter often terminating in large spherical swellings 37-55^ thick, which strikingly resemble the oogonia of certain species of Cystopus, except that the swellings are usually empty. Gleba whitish at first, changing'to pale green and then to light brown with a greenish tint, and finally blackish brown on drying; without any signs of a sterile base. Tranial plates arising from the peridial wall and passing inwards in a more or less radial fashion, in some uniting in the center to form a fairly distinct columella. Cavities of the gleba subrotund in the central region, up to 0.6 mm. wide, becoming narrow and radially elongated toward the peripheral region; empty at first, becoming nearly or completely filled with spores. Hymenial layer concolorous with the tramal plates; composed of 46 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA young and old basidia 3-7 x 16-25/u long, which, when young, are cylindrical but which collapse after the spores are formed. Spores 2-4 to a basidium, smooth, elliptic, deep brown under the microscope, 6.5-7.4 x 10-13,u (not counting the utricle), with an open cup on the proximal end (at first appearing like two prongs), the spore body surrounded at some distance by a very thin, hyaline, bladdery utricle, which is in contact with the spore only at the cup end. The surface of the utricle is faintly rugulose. This plant clearly belongs in the Hymenogastraceae in the obvious origin of the tramal plates from the peridium. Of the genera in this order it seems closest to Hy- menogasler in the absence of fibrils from the sides and top of the plants and in the structure and shape of the spores, a utricle being present in several species of that genus. However, the appearance of the gleba is more like that of Hysterangium, with its long, radially elongated chambers, stuffed or nearly so at maturity, radiating in many cases from a distinct, subgelatinous, central column. The complete continuity of the tramal plates with the peridium, however, is so striking that the plant cannot be placed in the family Hysterangiaceae. We have carefully examined the descriptions of the thirty-four species of Hy- menogaster listed in Saccardo, Vol. 19, and find that our plant can be separated from each of them by obvious characters. In the color of the gleba, the shape of its cavities and the shape and size of the spore body, our plant resembles H. ulriculatus Harkness, but that can be separated easily by the chocolate brown peridium and the fact that the utricle of the spore is winged or angled. Moreover, no mention is made by Harkness of any odor, while that of our plant is so strong and distinct as to be easily noticed by the most casual observer. So penetrating in fact is the odor that the plants, if partly uncovered by rain, can be located in the woods before being seen (10 or 15 feet away). A pitcher of water put in the ice box with a dish of these plants was so im- pregnated with the odor as to be nauseating. The present species is apparently nearest H. Thwaitesii Berk, and Br., in that both species are externally white and internally brown, and the spores of both plants are covered by a utricle. The two plants, how- ever, can be separated by the distinct difference in the shape and structure of the spores. Those of H. Thwaitesii are larger and the proximal end is without a cup. Moreover, the utricle is attached at both ends of the spore instead of only one end as in our plant. Also, no mention is made of odor in H. Thwaitesii. The New York plants which we are referring to H. Thwaitesii differ strikingly from the present species in the thinner peridium, the empty chambers of different shape, and much lighter color of the gleba. Among our plants the present species can be easily recognized when fresh by the peculiar and intense odor and in all conditions by the distinct utricle covering the small spores. Hymenogaster decorus Tul. also has spores with a rounded distal end or very obscurely pointed and surrounded by a utricle, but it is a much larger plant, has much larger spores and is nearly odorless. Dendrogaster connectens Bucholtz (Hedwigia 40: 316. 1901) is easily different, as shown by the brown surface, yellow gleba, more extensive sterile tissue, and much larger spores. No odor is mentioned. 7467. Partly buried in soil by branch under beech trees, by old Hillsboro road about 4 miles from Chapel Hill, July 30, 1924. 7473.

Hymenogaster Thwaitesii Berk, and Br. Plate 109 A plant collected by Mr. A. H. \V. Fovah among roots of sedges at Syracuse, New York, has been determined and reported by Lloyd as Hymenogaster decorns (Myc. Notes, p. 1166). We have a bit of this collection and on comparing it with Tulasne's original description we are convinced that it is not that species but rather an American form of II. Thuaitcsii, a plant described from England and which has apparently not been found since. The New York plants are very small, in the dry state about 3 mm. or less. The interior is not at all purplish but sordid ochraceous. The chambers are comparatively large, about 3-4 to a mm. and rounded and largely empty. Surface glabrous, pallid ochraceous or paler, much wrinkled on drying. Spores oval to subelliptic, with distal end rounded or somewhat pointed, surrounded by a hyaline sheath, the body of the spore 9.2-11 x 11-17.3/u. The spores agree very well both in size and structure with those of the type of H- Tkumiesii, a preparation of which was kindly sent us by the Director of Kew Gardens. We find the latter to be 8.5-11 x 14-20/z, not counting the irregularly crumpled, hyaline sheath surrounding them, more or less pointed at each end. The English plant has spores prevailingly more pointed than the American, as will be seen from our figures, but the general characters are so similar that the American plant had best be considered only a form. The original description of H. Thwaitesii gives the spores as globose, but this is not the case. Tulasne's figures also taken from the type are drawn somewhat more globose than we find them to be. The spores of decorus are much larger and the gleba is purplish. Also the plant itself is much larger. Illustrations: Tulasne. Fungi Hypogaei, pi. 10, fig. 11. New York. Syracuse. Povah, coll.

Fruiting bodies subglobose, oblong or lobed; exposed or underground. Peridium thin, nearly smooth, not netted with veinlike strands. Gleba fleshy, elastic, intimately connected with the peridium and not separable from it; cavities rather large, hollow (at least when young) ; sterile base present or absent. Basidia 1-4-spored; spores spheri- cal or subspherical, with warted to reticulated walls. Two species have been reported from the eastern United States and we are adding a new one. To separate this genus from Hydnangium has proved practically impossible. We agree with Lloyd (Myc. Notes, p. 269; also p. 1139) that it is best to unite them and have done so in the above description. In this last publication Lloyd reunites the genera and treats all the species known by him. 48 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA For cytology of spore formation in Hydnangium carneum see Rhuland (Bot. Zeit. 59: 187. 1901). In this plant Rhuland finds basidia in a single fruit body to have 2, 3 or 4 spores. There are 4 nuclei in each basidium. In the two-spored cases each spore may contain two nuclei or one may contain one and the other three. In the four-spored cases each one contains a single nucleus. In the spores further division of the nuclei may take place producing nuclei up to six. Bausch (Bot. Zeit. 18: 352. 1926) states that this behavior of nuclei, that is more than one entering a single spore from the basidium is the only case proven. For Hydnangium carneum also see further Bambeke, Mem. Acad. Roy. Sci. Belgique 54: 1903 and Klika, Mykologia 2: 143, 3 text figs. 1925.

De Toni Plates 29 and 110 Plants superficial or partly underground, gregarious and often crowded, subglobose to oblong-lobed, usually flattened when large, 1-3 cm. wide, 0.6-1.5 cm. high; bay red to chestnut or Sanford's brown when fresh, paler and more or less plicate underneath; surface quite smooth, dull (not flocculent) ; rooting by a small white myceloid base, no fibrils present; peridium wall simple, 130-150/j thick, its context reddish brown under microscope, consisting of much tangled, closely packed hyphae. Gleba creamy white, becoming pale rose when cut, exuding a white, tasteless milk which also becomes faintly rose colored and more watery upon exposure to air; cavities of the gleba large, about 0.3-1.5 mm. long or wide, labyrinthiform, quite hollow until deliquescence and easily visible without a lens; septa 110-190/* thick, consisting of (a) closely packed, irregular hyphae, 3.7-6.2/* thick, (b) elongated, laticiferous sacs, and (c) the two conspicuous hymenial layers which are 40-50/i thick and without cystidia. Odor when fresh rather faintly aromatic and very like that of a certain group of Lactarias, e. g., L. theiogalus, as also noted by Berkeley for H. Stephensii. When rotting the odor is mildly fetid and moderately strong, not at all like the pleasant odor of Rhizopogon rubescens. Spores spherical, 11.8-16/* thick, with a short mucro and large oil drop, the surface set with irregular, imperfectly reticulated warts and ridges almost exactly as in certain species of Russnla and Lactarius. Basidia clavate or spindle-shaped, 8-13 x 45-65/1 counting the sterigmata, which are 7.5-14/* long and only two in number. Not rare in Chapel Hill on sandy soil mixed with moss and grass in low open woods among pines. The plants are seated on the surface and never more than about one- third submerged. After maturity the plants do not deliquesce as in Rhizopogon, but begin slowly to decay, the gleba and peridium becoming water-logged, the former getting much darker and usually spotted or covered with a blackish brown mold, the gleba not changing color, slowly the tramal plates break down and the gleba becomes a tough and elastic jelly, the disorganization proceeding gradually from the top and sides. Fissures PLATE 30 f 9 Octaviania purpurea.

Even when the plant is half rotted off above and shrunken like a dried plum, the structure of the gleba is still obvious below and all the plant remains tough and elastic. Weeks and probably months are required to complete the dis- organization. Reported from North and South Carolina, Florida and Alabama. Though Ravenel's plant was described as white by Berkeley (Grevillea 2: 33. 1873, as a var. of //. Stephensii) we have no doubt that our plant is the same. We have compared a collection labelled Octaviania Ravenelii from Alabama by Earle (N. Y. Bot. Gard.), who notes that the color was "uniform terra cotta red, after exposure the tops bleach to a dirty white." He also notes that the plants were growing singly on the ground in a pasture and were usually 1-2 cm. broad (up to 3 x 4 cm.). Our plants are the same as these in all characters, including the spores which we find to be in Earle's plants 11— 14/u, rarely up to 16.6/i, including the tubercles. Hydnangium Stephensii Berk, and Br. (Ann. & Mag. Nat. Hist. 13: 352. 1844) was transferred to Octaviania by Tulasne, but the characters that distinguish these two genera are very obscure. (See note under the genus.) The American plant is closely related to H. Stephensii, but the spores easily sep- arate the two species. The spores of H. Stephensii are short-elliptic and with slender, sharper spines and are not reticulated. Our fig. 7 on pi. 110 is drawn from a slide, which was generously prepared for us by Miss Wakefield from the type atKew. Tulasne and Massee draw the spores as elliptic, but with the spines more prominent than they appear to us. Quelet (Champ. Jura et Vosges, pt. 3, p. 18, pi. 1, fig. 9) shows the spore as subspherical (13/u thick) with small spines. It is interesting that he gives the color of the plant as whitish, the very character that made Berkeley describe the American plant as a variety of his "dark rufous" H. Stephensii. This suggests a similar fading in age. Corda shows the spores of 0. Stephensii as quite spherical and with short, sharp spines, not reticulated (6: pi. 7, fig. 67). Patouillard's drawing of spores (Bull. Soc. Myc. France 26: 201, fig. 1. 1910) of what he calls a form of Stephensii {Hyd- nangium galathejum) are as he notes just like those of the type of Stephensii. He further notes that in the type as in the form the basidium has but one sterigma. This makes a further distinction between Octaviania Ravenelii and 0. Stephetisii. In the fresh state a section of our plant showed a narrow, plug-like sterile base about 1-2 mm. thick. From this base two or three lines (in section) radiated and were plainly visible for about half way to the surface. When cut the milk exuded much more abundantly along these lines and from the sterile base. There is no sign of splitting in the tramal plates. In his original description of H. Stephensii, Berkeley does not describe the juice as turning red then yellowish on exposure as stated by Rea (British Basidiomycetae, p. 28) but says, "substance when cut and exposed to the air soon acquiring a red tinge, which is not however permanent and in young specimens vanishes almost entirely in drying, in which state the hymenium is cream colored." This is exactly the color change in our plants. Since writing the above we have seen notes on this species in the fresh condition by Prof. Povah of Alabama (Lloyd Myc. Notes, p. 1140. 1922). His observations are in close agreement with ours in regard to milk and color changes. The odor he describes as "suggesting to some strawberries, to another the odor of a freshly dug 50 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA sweet potato." The odor of the sweet potato is not very different from the Lactarius odor noted by us. 1445a. Beside a low place near Mason Farm, Oct. 28, 1914. 6026, 6042.

Peridium white throughout when young, turning vinaceous to deep vinaceous when exposed or wounded ; retaining the vinaceous tint on drying; 1-2 mm. thick when fresh, drying to about one-quarter this thickness; composed in large part of small thin-walled, densely packed and considerably entangled threads 3-4/x thick, and a few much larger thick-walled threads, 11-16// thick, which often terminate in large globose cells. Gleba pure white when young, acquiring an olive tint as the hymenium and spores begin to develop, passing through olive brown to deep blackish brown as the spores mature. Tramal plates pure white, becoming only slightly discolored upon maturity and contrasting strikingly with the nearly black spores and the more or less deep purple peridium; arising from the peridium and composing in the young state by far the greater part of the gleba, persisting in mature plants as very thin white byssoid plates. Cavities of gleba first arising as narrow, pouch-like spaces which by growing and anastomosing, form labyrinthiform spaces, which, in section, often appear in clusters, 3-8, separated by rather wide tramal plates, thus presenting the appearance of several small cavities within a large one; cavities becoming only partially filled with spores. Odor of fresh plants faintly like an Irish potato. Plants kept covered in the ice box for several days gave an odor strongly suggestive of oysters. Taste not unpleasant. Spores subsessile, subspherical, sometimes considerably elongated at the proximal end, angular-warted, 9. 5-12. 5m thick, with a pedicel about as long as the diameter of the spore. Hymenial layer, lining the cavities, composed of young and old basidia which are very peculiar in that in the young state they are thick, rather short cells, 7.4-11.2 x 20-25;ii, which by elongating into a narrow tube, 4.4-5. 5yu thick, more than double their length; mature basidium 5.5-7.8 x 30-44^, jug-shaped, bearing one apical spore; collapsing after the spores are formed. Suitable material being at hand, it was thought of interest to study the nuclear behavior in this single-spored basidium for comparison with that of the normal four- spored basidium. The material for this study was prepared as follows: small slices about a half millimeter thick of the youngest plants were cut and put in Flemming's weak chrom-acetic acid where they were allowed to remain over night.

Sections were cut S microns thick and stained with Haidenhain's iron alum haematoxy- lin and by Gram's method, the latter giving much better results. It was found that the nuclear behavior agreed in the essential details with that described for typical Basidiomycetes with four-spored basidia except that three of the nuclei remain in the basidium and degenerate, the fourth entering the spore which is always uninucleate. In the young basidium, which has not developed the elongated, tubular process, there were quite often seen two nuclei which might be located near the base or in center or in position as shown in figure 4. Numerous stages were seen in which the two nuclei were apparentlv fusing. When the basidium is in a somewhat later stage of develop- ment (fig. 5) it is usually found to be uninucleate, the nucleus now being considerably larger than either of those shown in figure 4. This large nucleus soon becomes some- what vesicular in structure, the linin threads with chromatin granules on them showing up conspicuously (fig. 6). A comparatively large spindle is formed on which the chro- matin granules arrange themselves (fig. 7). The first mitosis seems to be followed im- mediately by the second in which the spindle is considerably smaller and the chromo- somes much less distinct (fig. 8). Four nuclei are thus formed from the original fusion nucleus (fig. 9). Meanwhile the basidium has sent out a tubular process into which the nuclei and some cytoplasm migrate. At the tip of this tubular process a bud is formed which enlarges to form the spore. One of the four nuclei passes into the spore (fig. 10). In later stages as shown in figure 11, the spore is seen to be uninucleate; the three supernumerary nuclei left in the basidium can hardly be distinguished — so poorly do they absorb the stain. They are doubtless degenerating. Our plant is evidently nearest Hydnangium monosporum Boud. and Pat. (See Boudier; Icon., pi. 193, and Patouillard; Tab. Fung. No. 692) as shown by the strongly cespitose habit and single-spored basidia with rough spores. That is easily separated by ochraceous color, larger size, and minutely spiny spores. Gallacea Scleroderma (Cooke) Lloyd ( = G. violacea (Cooke & Mass.) Lloyd) , a violet plant from New Zealand and related to Hysterangium, has recently been examined microscopically by Cun- ningham, and is quite different from our 0. purpurea (Trans. Brit. Myc. Soc. 9: 193, pis. 9 and 10. 1924). The genus Leucophleps Harkness {Leucophlebs, as the spelling was corrected by Roumeguere) contains a species L. magnala which, in its one-spored basidia, resembles our plants, but which can be easily separated by the partial absence of the peridural and the smooth spores. Appearances are against Leucophleps being a good genus. 7456. Plants partly or entirely buried in damp soil by Battle's Branch below Forest Theater, July 25, 1924. 7468.

Plate 110 Dr. Fitzpatrick has kindly sent us a single plant of this species from Ithaca (entered below), mentioned by Lloyd in Mycological Notes, p. 1141. We find it to agree with 52 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA the descriptions by Tulasne and Boudier so far as can be seen from specimen kept in formalin. The peridium is irregularly areolate, salmon colored, usually about 100/j thick, composed of densely packed tangled threads. Tramal plates continuous with the peridium, considerably thinner than the peridium and much lighter colored, ap- pearing almost white; glebal chambers rounded or elongated, usually filled with spores, 0.5-1.5 mm. wide. Spores round, 13-17/* thick, light brown under the micro- scope, very dark brown in mass, conspicuously set with large pyramidal spines and often with a short pedicel. The following description is from Boudier, Icon. Myc. 4: 97: "Peridia white, rounded, solitary or cespitose, and more or less irregular, covered with a light tomentum which is separated into small, tomentose, flatfish warts, white at first, then turning smoky gray; cortex turning more or less bluish green by cold or ex- posure to air; the peridia are attached to the earth by root-like, mycelial filaments which form a very visible base. The gleba is full, firm, formed of rounded chambers, filled with spores and separated from each other by the whitish plates which seem to arise from the basal portion, and which are colored equally green by cold. The spores are perfectly round, echinulate, brownish drab when seen one at a time, and purplish brown when seen in mass, which makes a section of this species appear finely marbled with white by the plates; they have a large internal oil drop often divided, and are often furnished with a pedicel; they measure 15— 18/x in diameter with the spiny warts." "This species seems rare; I have found the specimens which I have figured in damp woods of the forest of Montmorency in Sept. ; it was there in numbers under the leaves at the foot of a clump of ash trees."

SECOTIACEAE Fruit body above ground and with a short or long stalk which extends as a col- umella entirely through the peridium and is connected with it above; gleba chambered, the tramal plates arising like the gills in an agaric and growing into a gill chamber, anastomosing and crumpling to form numerous irregular cavities which are lined on the inner side by a typical agaricoid hymenium ; tramal plates persisting after the matura- tion of the spores; capillitium absent. Dehiscence ventral around the stem with sub- sequent expansion and in some cases longitudinal cracking, or there may be no true dehiscence (as in RJiopalogaster), the very thin peridium disappearing more or less by collapse. Basidia clavate with distinct apical sterigmata. The family as above described is so modified from that of Fischer as to include only the genera Secotium and RJiopalogaster (possibly also Macowanites). We are following Fischer in not considering Elasmomyces as distinct from Secotium. This is about as suggested by Cunningham (1. c, p. 223). A very interesting family with characters suggesting the agarics and apparently connecting them with the Hymeno- gastraceae, which they resemble in later stages of glebal development. Only two genera have been found in the eastern United States. It is interesting to compare here the peculiar genus RJiacophyllus B. & Br. (Trans. Brit. Myc. Soc. 11 : 238. 1926) from the tropics, which externally has the exact appearance of a small, delicate agaric with conic cap. Petch has recently been able to study the plant in all stages. Instead of gills there are borne on the underside of the cap more or less linear groups of bulbils which germinate easily and are the only reproductive bodies. These bulbils arise separately inside a delicate fundamental tissue. They may be at first hollow, soon becoming solid through growth of the palisade-like central tissue. This tissue produces on the inside subspherical cells in rows. It is not stated from what cells of the bulbils hyphal threads originate in germination. Key to the Genera Peridium tough and persistent Secotium Peridium very delicate and disappearing in part at maturity Rhopalogasler SECOTIUM Kunze Peridium above ground with a long or short stalk, which extends entirely through the sporiferous portion as a stout columella which is continuous above with the pe- ridium. Gleba spongy, cellular; tramal plates arising from the peridium wall and also connected with the top or greater part of the columella and filling the space between them, somewhat lamellate, very sinous with a more or less horizontal direction sug- gesting an unopened agaric with sinuous gills; capillitium not present. Dehiscence basal and longitudinal, the peridium usually separating slightly from the stem below and in some cases expanding more or less, after the manner of a young agaric. Basidia clavate with 2-4 apical, stipitate, smooth or rough spores. For a good drawing of the hymenium of 5. krjukmvense, a European species with rough spores, see Bucholtz, 1. c, pi. 3, fig. 4. 53 54 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA The genus seems to be particularly abundant in Australia and New Zealand, from which Cunningham (1. c.) reports 16 species. He adds the following facts to our knowl- edge of the cytology: "The hyphae of the columella, stipe and peridium are invariably binucleate. The basidia at first are binucleate, these nuclei fuse, and a slightly larger fusion-nucleus is formed. This takes up a position in the distal end of the basidium; there it divides twice. The first division precedes the formation of the sterigmata, the second succeeds their appearance. When the sterigmata are about half their normal length, spores begin to appear on them, and when they are full length, the spores are about half size. When the spores are about one-quarter their normal size, a nucleus migrates into each, divides mitotically, and the spores become binucleate, a character constant in each of the numerous species examined. The spore attains its full size before it changes colour ; at maturity the epispore becomes coloured some shade of brown, the depth of colour depending on the species. "Clamp connections are abundant in the tissues of the stipe and partial veil "On germination a germ tube protrudes, usually from the end of the spore oppo- site to that by which it was attached to the sterigma; this branches repeatedly to form a mycelium, the cells of which are septate and binucleate." Conard and Cunningham, working on different species disagree as to the presence of a veil, Conard claiming the presence of universal veil and absence of a partial one and Cunningham stating just the reverse.

Peridium nearly pure white when young and fresh, turning straw color to cinnamon-buff or leather color upon maturing and drying; single-layered, 1-3 mm. thick, nearly smooth in very young specimens, covered at maturity with inherent scales which may resemble fish scales or may be very irregularly arranged; fleshy and tender when young, becoming rather tough and fibrous upon drying.

Tramal plates PLATE 32 Secotium agaricoides. Xo. 7091 [two small plants] ; No. 7119 [others] SECOTIACEAE 55 about 75m thick, persisting in the mature and dried specimens, forming lamella-like folds. Odorless when young; taste sweet and nutty like that of Boletus edulis. Edible when young. Spores (of Xo. 7091) smooth, ovate, yellow under the microscope, 5.5-6.8 x 6.6-8/1, a few irregular, larger ones. Hymenium 25-30/n thick; basidia club-shaped, 4-spored, 7.4-9.3|i thick, no cystidia. This is the first record so far as we can find of this fungus in the southeastern states, but at the New York Botanical Garden we find a collection from Virginia by Dodge (as 5. acuminatum). The only record we find of its occurrence in the Atlantic states is from Pennsylvania (Barnett, as 5. Warnei; Peck, 1. c, 1882). It is apparently not rare in the Mississippi Valley and westward, and is reported from Alabama and Texas. This is the same as the plant described by Peck from Wisconsin as Lycopcrdon Warnei (Bull. Torr. Bot. Club 6: 77. 1876) and later transferred to Secotium (Ibid. 9: 2. ISSJi. We have examined and compared specimens and spores of S. Warnei from Ne- braska (X. Y. Bot. Gard. Herb.; H. J. Webber, coll.) and specimens and spores of S. agaricoides from Hungary (N. Y. Bot. Gard. Herb., determined by Hollos) and find that they both agree with our Chapel Hill plants. We agree with Hollos that S. rubigenum Harkness (Bull. Cal. Acad. Science, 1886, p. 257) is the same as the present species. A specimen at the New York Botanical Garden from California, collected by Harkness himself, has spores smooth, oval-elliptic, variable in size, 4.8-6.8 x 7-10.5^. Secotium arizonicum Shear and Griffiths (Bull. Torr. Bot. Club 29: 450. 1902) seems to be a good species, as shown by the much larger spores (7.2-12 x 8.5— 15m) of the type material in Washington (pi. Ill, fig. 14), and by the short, often aborted columella (see note by Lloyd, Myc. Notes, p. 149). Secotium tenuipes Setchell (Journ. Myc. 13: 239, pi. 107, figs. 4-8. 1907) and S. russidoides (Setchell) Lloyd (published as Elasmomyces) are also good species, growing entirely concealed under leaves in California. At the New York Botanical Garden is an abundant collection of the former by Harper from Berkeley, California (type locality) . The plant (when dry) is small, blackish red with a slender stem and a deep reddish brown gleba. The spores are deep brown, smooth, ovate, 8.5-10.2 x 12-16//. Secotium australe Lloyd (Myc. Notes, p. 788) is also apparently a good species, as the spores are said to be only 4-5/x thick. Lloyd has seen the types of S. decipicns Peck (Bull. Torr. Bot. Club 22: 492. 1895) and thinks it the same as the European Gyrophragmium Delilei (Myc. Notes, p. 150). Later he uses the name G. decipiens and calls it the western form of the European species (Myc. Notes, p. 196). Illustrations: Bucholtz. Beitr. Morph. und Syst. der Hypogaeen (Tuberaceen und Gasteromyceten), pi. 4, fig. 19. Fries, Th. C. E. Sveriges Gasteromyceter, fig. 7. Hollos.

Arts and Sciences 38: 61, one plate. 1903) that the following species, commonly known as Cauloglossum transversarium, cannot be retained in that genus which is really a synonym of Podaxon. He proposes for the species the monotypic genus FJiopalogaster. Johnston defines the genus as follows: "Fruiting body clavate, stipitate, traversed by a firm subgelatinous axil columella continuous with the stipe. Stipe firm, erect with naked base. Peridium simple, continuous with the stipe below and with the columella at the apex, more or less eva- nescent-indehiscent. Gleba persistent. Tramal plates extending from the columella toward the peridium. Basidia clavate, in groups, 4-spored, spores simple, borne on well-developed sterigmata." Rhopalogaster transversarium (Bosc) Johnston. Cauloglossum transversarium (Bosc) Fr. Plates 41 and 111 This plant of the southeastern Gulf states was first collected in the Carolinas but was not well known structurally until the work of Johnston (1. c). It has been found at Wilmington in abundance by Curtis and by Wood, and we have a collection from Nag's Head, N. C. As our dried plants are not in good condition we copy the following description from Johnston's paper, which see for much fuller structural detail and discussion of synonomy: "Narrowly to broadly club-shaped, 3-7 cm. high; the distal end of the columella appearing at or near the apex, either as a shallow orbicular depression, or a slight pro- tuberance. Peridium dirty brownish or buff yellow. When young the gleba is dirty gamboge yellow; when exposed by injury becoming dirty olive brown, eventually dark. Stem nearly white when fresh. Spores ovate-elliptical, 3.6-4.3 x 5.8-7.2^, yellow brown, borne on long slender sterigmata. The plants grow out of the bases of living or dead trees or upon rotten wood, stumps or fallen logs, or among rubbish on the ground close by in wet pine lands. September-November. S.

Peridium consisting of more than one layer (very obscure in Calvatia rubro-flava, and in some Lycoperdons where the outer layer may consist of only scattered particles or flakes). Gleba at maturity breaking down into a dry powder which contains the spores. Capillitium always present but sometimes (as in Disciseda) obscured by fragmentation after maturity. Basidia borne in a distinct hymenium surrounding small chambers or (in Disciseda) scattered in irregular groups without a distinctly organized hymenium or chambers. Basidia club-shaped with four (rarely fewer) spores borne on apical sterigmata; spores growing to full maturity on the basidia. It will be noticed that this description does not include the genus Arachnion. We have found it impossible to retain it and have any character left to determine the Lycoperdaceae. The lower part of the fruit body is often sterile and persistent and composed of larger compartments than the fertile part above. The former is called the subgleba and from it may extend up into the fertile tissue a more or less well developed column of sterile tissue called the columella. In most species the spores escape from a single, definite apical pore in the inner peridium. In Myriostoma there are several mouths, in Disciseda a basal mouth and in Calvatia no definite mouth, the whole upper part of the peridium flaking away. The family includes all the well known puffballs and earth stars. The larger puffballs when young and white (before the spores begin to ripen) are not only edible but very palatable and they should be much more used as food. For literature see under the order (p. 194) and genera. Key to the Genera Fruit bodies small, densely clustered on a common, leathery subiculum covering the substratum Diplocystis (West Indian) (p. 143) Not as above Outer peridium (cortex) thin, mostly peeling off in flakes or wearing away; inner peridium thick, firm and corky when dry, opening from above by irregular flaps and fissures, capillitium of separate threads with thorny prickles and a few short branches . .Mycenastrum (p. 101) Outer peridium thin, mostly peeling off in flakes; innerperidium opening by an apical pore, firm and resilient, retaining its form for some time after maturity; capillitium of smooth, separate threads with slender, pointed branches; mature plants loosened from place of growth and rolled about by the wind (the tumblers) Bovista (p. 97) Outer peridium thick or thin, scaling off in flakes or particles or wearing off by degrees or more or less persistent; inner peridium usually flaccid and collapsing or breaking up as the spores emerge; plants normally remaining attached to place of growth Capillitium of separate threads with slender, pointed branches Bovistella (p. 94) Capillitium of long interwoven threads that are not separable into unbroken units (in the case of Calvatia breaking up into short pieces except in some specimens of C. data) Peridium opening by a definite mouth Lycoperdon (p. 69) Peridium irregularly ruptured by the scaling off of fragments above; plants large (at times small in C. rubro-flava) Calvatia (p. 59) 58 LYCOPERDACEAE 59 Outer peridium thick, splitting at maturity into star-like rays from above downward and remain- ing attached to the inner peridium by their united bases Inner peridium with a single, apical mouth Ceaster (p. 102) Inner peridium with several mouths and several pedicels Myriostoma (p. 138) Outer peridium splitting horizontally around the middle, the upper part with the inner peridium attached breaking away and leaving the lower part in the ground as obscure fragments or an obvious cup Disciseda (p. 139) CALVATIA Fries Plants large to very large, globose, flattened or pyriform, etc., with or without a thick, stalk-like, sterile base; cortex thin, even or areolated (absent in C. rubro-flava) ; inner peridium thin, delicate, not opening by a pore but falling away irregularly in scales and plates from above downward and exposing the densely woven capillitium composed of long, much branched threads which at maturity in most species are easily broken into short pieces; sterile base (nearly absent in C. maxima) concave above, persisting a long time as a cup-shaped remnant, easily distinguished from Lycoperdon by the irregular scaling away of the peridia at maturity, and in most species by the fragility of the capillitium. The sterile base is in most species sharply delimited by a diaphragm, and in this case is obviously cellular. In C. rubro-flava and C. maxima there is no diaphragm and the sterile base is homogeneous at maturity. The genus includes the large puffballs, one species (C. maxima) reaching the enor- mous width of three feet or even more. They are important sources of food and should be used whenever found in the young condition with white interior, but note that the edibility of C. rubro-flava is not known. A neighbor of ours had some cooked and reported that they were too bitter to eat. They may be poisonous. In regard to the edibility of puffballs, it is interesting to note that Porcher (Resources of Southern Fields and Forests, 2nd ed., p. 699. 1869) quotes a letter from Ravenel as follows: "It has been mentioned by medical writers that the spores of the puffballs have narcotic properties, and it is an anaesthetic agent, acting somewhat like chloroform when inhaled, but I have never experienced any effects of the kind from its use as a vegetable. However, Dr. Harry Hammond, of Beech Island, S. C, writes to me, 'since writing to you, I and a number of others have made several meals on Lycoperdon, and I think I have discovered in myself well marked evidences of a narcotic influence — and two other experimenters have described similar sensations to me. I recollect also to have heard from Mr. Mahan that a friend of his, a physician in Georgia, had been seriously affected in this way by too large a meal on Lycoperdon.'1' From the context it would seem that the puffball referred to is not C. maxima, as stated, but C. cyathiformis, as the spores are spoken of as purplish. This note need not deter one from eating these puffballs, as they are among the most esteemed of edible fungi. The ripe contents of the larger puffballs have long had a reputation for stopping the flow of blood (see, e.g., Lind, Danish Fungi as Represented in the Herbarium of E. Rostrup, p. 401).

Key to the Species Peridium apparently single, the outer peridium being represented by only a delicate furfurescence, very thin; subgleba homogeneous at maturity; all parts turning yellow when bruised before maturity; spores yellow-ochre in color C. rubro-flava (p. 60) Peridium single, or at least not separable into two distinct layers, thick; gleba bright olivaceous C. pachyderma* Peridium double, outer layer thick, inner layer thin Gleba olivaceous yellow C. lepidophorum* Gleba purplish brown C. cretacea (p. 66) Peridium double and separable at maturity into a thin outer and a thicker inner layer; subgleba, if present, chambered at all ages; not turning yellow when bruised; spore color purplish or brown or olivaceous yellow Plants very large, almost entirely filled with the gleba; sterile base nearly absent; mature gleba greenish yellow C. maxima (p. 62) Plants rather small; subgleba nearly absent; mature gleba dark purplish; spores nearly smooth C. fragilis (p. 64) Plants large or moderately small; sterile subgleba large and persistent Spore powder dark purplish; plants large; spores strongly warted C. cyathiformis (p. 63) Spore powder brown; plants rather small; spores minutely warted C. data (p. 65) Spore powder dull or bright olivaceous yellow; spores smooth or nearly so Capillitium threads about as thick as the spores and with circular holes in them; spores very small C. craniformis (p. 67) Capillitium threads much thicker than the spores and with long linear pits; spores larger C. caelata (p. 68) Calvatia rubro-flava (Cragin) Lloyd C. aurea Lloyd Plates 33, 34 and 112 Plants subglobose, flattened on top, 2-10 cm. wide by 1.5-5 cm. high, strongly plicate beneath, usually with a short, abruptly pointed stalk which is centrally attached by one or more slender root-like strands; usually nearly white when fresh and immature with a faint tint of pink or lavender but varying to pinkish leather color, all parts turning at once to brilliant yellow (about chrome yellow) upon rubbing or cutting, drying orange or yellow orange to orange red or bay, in age becoming a metallic brown. Peridium about 125-160/x thick when fresh, becoming very thin and naoery on drying, practically single layered, the outer layer being represented by only a delicate fur- furescence, becoming smooth and shiny on exposure to weather, cracking up into irreg- ular areas and falling away after drying. Gleba pure white when young and lined with a hymenium as in Lycoperdon; the cavities very minute, up to about 0.2 mm. • Calvatia pachyderma (Peck) Morgan and C. lepidophorum (Ellis) Lloyd are two western species which are sometimes confused. Both have thick peridia but may easily be distinguished by the following characters: In the former the pale peridium is smooth or with thin adherent, white patches and there are no separable layers, although the entire peridium is apt to be scissile like short-cake; spores (in plant from type locality, collected by Pringle and determined by Peck) oval to elliptic, very finely warted under high power (x 2160), 3.5-4 x 4.2-6/x, with a mucro or short pedicel; capillitium threads fragmented, strongly oliva- ceous yellow under microscope, irregular in thickness, rather frequently branched, pitted, up to llji thick in swollen places; mature gleba bright olivaceous. In C. lepidophorum the outer peridium has an extremely thin, glazed surface marked with inherent patches or rounded "bosses" but this is not separable. Beneath the thick outer peridium, unlike any other American Calvatia, the gleba is covered by a thin, papery membrane and this is the character which most easily determines the species. Spores spherical, distinctly warted, 4.2-c3/i. Capillitium threads slender, fairly even, up to 5/i thick, brown, occasionally branched, and not so sinuous as in C. pachyderma. The plant Morgan described as C. pachyderma is C. lepidophorum, as noted by Lloyd, and not Peck's species. Lloyd proposed the genus Hypoblema for Ellis's Lycoperdon lepidophorum (Myc. Notes, p. 140) but later reduced it to a subgenus of Calvatia (Footnote 13 to Index to vol. 2). to W H < *' Af^f 1 3 < LYCOPERDACEAE 61 long in section, labyrinthiform, becoming larger and more indistinct as they pass into the subgleba, tie cavities of which are up to about 1 mm. long, empty when young, but becoming loosely filled with soft, woven threads toward maturity so as to obscure their outlines. At full maturity this growth has in most cases entirely obliterated the outlines of the chambers and the subgleba is homogeneous. At times the orig- inal chamber wall may still be noticed, although the cavity is stuffed. This last con- dition is shown in one of the plants on pi. 33. Subgleba occupying a comparatively small part of the peridium, about 3 mm. to 2.5 cm. thick below, depending on the size of the stalk, but running as a thin layer far up around the sides of the gleba. Gleba and subgleba changing when cut or wounded from a pure white to a brilliant yellow, the color change appearing first in the subgleba and slowly spreading over its surface and then over the surface of the gleba. Gleba changing to honey yellow or Isabella color when fully ripe, the subgleba more brownish and often with a tint of chocolate. Glebal chambers usually incompletely breaking down, particularly in the region just beneath the peridium so that erosion is very slow, the gleba remaining as a soft, spongy mass like a powder puff for a long time after exposure. Taste pleasant and odor weak when fresh ; a decidedly strong odor of old ham on drying. Spores (of No. 7163) nearly yellow ochre, between that and buckthorn brown of Ridgway, spherical, very minutely rough even under high power (x 2160) with a hyaline outer membrane and a colored inner one, 3^1.4^ thick, with a short pedicel. Basidia subglobose, about 6-8/j. thick, with 2-4 sterigmata. Capillitium threads up to 4.4/i thick, considerably septate, moderately thin-walled and remarkable in the frequent occurrence of distinct holes, 1-3/x in diameter, in the walls, sinuous, usually breaking into short pieces when put under a cover glass. This is certainly C. aurea Lloyd (Myc. Notes, p. 11) and it is probably true as Lloyd thinks that C. rubro-flava is the same (Myc. Notes, pp. 32, 90, 149). We have not seen any authentic material of the latter, but the description agrees. The species differs sharply from all other Calvatias in the single layered peridium and homogeneous subgleba at maturity. These characters are probably of enough importance to entitle the plant to a genus of its own. The long persistence of the soft gleba makes these very clean puffballs to handle, and is in sharp contrast to the easily fragmented and dirty habit of C. caelata, etc. A homogeneous subgleba at maturity is, so far as we know, found in no other puffball except C. maxima, C. Candida and Lycoperdon poly- morphic (L. cepaeforme). The present plant is in fact very closely related to C. Candida, and Cunningham reduces it to a variety of that species. The striking color and the remarkable color change of fresh plants when injured lead us to retain it as a species, at least until more is known of C. Candida in the fresh condition. The latter is not known to occur in America. A peculiarity of the color change when a fresh young plant is rubbed is that the bright yellow color persists only for a few minutes, then fades away to the original tint. The species seems confined in our country to cultivated soil, and this suggests that it is an introduction, probably from South America. It is reported by Lloyd from Alabama, Missouri, Ohio, Indiana, Washington, D. C., and Connecticut, and we are adding several other stations. Cragin's plant was found in Kansas. Our record is the first for this state. It is also reported from Brazil, Bolivia, Australia, and Japan. Illustrations: Lloyd. Myc. Illustrations, No. 22 (asC. aurea). 7107. On a lawn, Sept. 2, 1923.

Plate 112 We take the following description from Morgan (1. c, p. 166): "Peridium very large, globose, depressed-globose or obovoid, with a thick cord-like root. Cortex a flocculose or nearly smooth continuous layer, very thin and fragile, white or grayish, changing to yellowish, drying up and becoming brown, remaining closely adherent to the inner peridium or sometimes peeling off in patches ; inner perid- ium thin and very fragile, after maturity gradually breaking up into fragments and falling away. Subgleba very shallow or quite obsolete, when present said to be compact and not cellular; mass of spores and capillitium greenish yellow, then brownish oliva- ceous; the threads very long, frequently septate, branched, the primary branches much thicker than the spores, the ultimate ones more slender; spores globose, even or some- times very minutely warted, 3.5^1.5^ in diameter, often with a minute pedicel." We have examined a specimen from Madison, Wisconsin, and find the spores to be smooth, subspherical, 3.5-4ju thick, with a short pedicel and a distinct oil drop; capil- litium threads easily fragmented, occasionally branched, about 5.5yu thick. It is surprising that we have not found this huge puffball in Chapel Hill, nor has Beardslee found it at Asheville. Both Schweinitz and Curtis report it, the former say- ing that it may reach a breadth of three feet, but his finding it in this state is doubtful as the Bovista giganlea of his herbarium is Calvatia cyathiformis (also noted by Lloyd, p. 396). It occurs in meadows and is excellent food. In American Naturalist (18: 530. 1884) Professor C. E. Bessey records a specimen of the giant puffball found by Professor R. E. Call in Herkimer County, N. Y., in 1877, that was 5 ft. 4 in. x 4 ft. 6 in. x 9| in. This, says Professor Bessey, is by far the largest on record. Buller (Researches on Fungi, p. 85) has estimated that a large fruit body of this species (40 x 28 x 20 cm.) contained over seven trillion spores. The species is said by Dearness to be fairly common in Ontario. Illustrations: Batsch. Elench. Fung., pi. 29, fig. 165. Berkeley. Ann. Sci. Nat., 2nd ser., 12: pi. 2, figs. 7-14. 1839. Boudier. Icon.

Lycopcrdon cyathijorme Bosc Bovista lilacina Berk. & Mont. Plates 35, 36 and 112 Plants nearly globose or turbinate, 7.5-15 cm. thick, attached below by a short root; cortex smooth or slightly scaly, the upper part often cracking into areas. Inner peridium thin and delicate, at maturity scaling away by degrees together with the cortex to expose the dark purple interior; lower, sterile part (subgleba) remaining intact as a persistent, dark, cup-like base which may remain in place over winter. Gleba at first white, then changing through yellow to deep purple brown as the plant matures. Spores (of No. 550) globose, with numerous distinct spines, 4.4-6. 5ju thick, ex- cluding the spines. Capillitium threads up to 4.3/i thick, very long, sparingly branched, interwoven, considerably septate and breaking into sections at the septa, walls with minute pits which are not easily visible except under high power. The species is common in Chapel Hill from July to late autumn in open places, uncultivated fields, lawns and orchards. When it is young and the inside white it is excellent food when fried like an egg plant. Some interesting facts concerning this Calvatia have been brought out in a study by Shantz and Piemeisel (Journ. Agric. Research 11, No. 5: 191. 1917). They find that the so-called "fairy rings" caused by this fungus advance about 24 cm. a year. One ring has been found which is estimated to be 420 years old. The grass is stimulated just behind the fruiting bodies of the ring, and forms a deeply colored, luxuriant growth, whereas it is dry, often dead over the mycelium of Agaricus tabularia and Marasmius oreades and shows a luxuriant growth on both sides. When disturbed, as by being plowed up, the rings cease to fruit, and cannot be detected in vegetation, while in the closely related species, C. polygonia, they continue to grow and fruit, as is also the case with Agaricus tabularia. Cunningham considers C. novae-zelandiae Lev. an additional synonym for this species (Trans. N. Z. Inst. 57: 191. 1926). Illustrations: Cunningham. Trans. N. Z.

Morgan Plates 37 and 112 Fruit body obovate, up to 5.5 cm. thick (in our collections), the base abruptly contracted to a blunt point; cortex thin, separable, brownish to straw color, the surface minutely felted to smooth and usually areolated or pitted (in a form quite smooth), the larger depressions usually with a central flat, purplish brown scale with the edges more or less free; inner peridium deep purplish brown in section, about 0.7 mm. thick, brittle and breaking away by degrees in irregular fragments from the top downward. Gleba at maturity deep purplish brown, soft but not very powdery and not falling out easily as in C. caelata. Subgleba often almost absent, at times more obvious when the base is pointed, brown, the cavities very small and obscure. Spores (of No. 4783) dark brownish purple, spherical, smooth or minutely warted, 3.7-4.6yu, rarely 5.4ju thick. Capillitium of short segments, irregular, sinuous, 3.5-6/x thick, pits very minute and not easily visible except under high power (just like the capillitium of C. cyathiformis). This species is distinguished from C. cyathiformis by its small base with very little subgleba, the smaller size of the plants, and the nearly smooth spores which are of smaller average size. Calvatia caelata is of course separated by its gleba color and by the much thicker and peculiarly pitted capilhtium. The surface appearance of the typical form of the present species is almost exactly like Lloyd's figs. 2 and 4 and, in part, fig. 3 of plate 36 of C. caelata and form, but that is, of course, excluded by the purplish spores of our plants. Calvatia pachyderma differs distinctly in the olive brown or buffy brown gleba, homogeneous but scissile peridium of uniform color throughout and without a sharply contrasting cortex, and in the average larger size of the capillitium.

A plant from Colorado is quite similar to these, except that the areolations above are very pronounced, so that the tendency is for each areolation to break away separately, bringing its part of the inner peridium with it. The smooth form mentioned above is represented by plants from Kansas and Nebraska entered below. The peridium is quite smooth, tan to brownish tan; all forms are otherwise the same. Illinois. Urbana.

Calvatia elata (Massee) Morgan Plates 26, 38 and 112 Plants small for this genus, with a distinct, usually long, subcylindrical, often pitted stalk up to 4 cm. thick and 8.5 cm. long (rarely longer) and a subglobose head about 3-6 cm. thick; color when mature pale brown to leather color; cortex only a very thin granular or powdery, persistent layer that is almost absent on the stalk below; inner peridium thin and at maturity very fragile, soon cracking up into fragments and falling away or adhering for awhile to the capillitium. Gleba brown; the subgleba of the stalk with distinct empty chambers of fair size. Spores (of plant from Litchfield, Conn.) spherical, very minutely warted, short- pedicellate, 3.5-4.4/z. Capillitium threads much fragmented, moderately pitted, up to 5m thick. The species was described by Massee as Lycoperdon datum from New England plants in the Berkeley Herbarium, where it was included as L. saccatum. We have seen a good example of C. saccata from England (N. Y. Bot. Garden, from Cooke) and find that the spores are larger and rougher than in our C. elata (distinctly warted, 4.5-5.5/0, thus confirming Morgan's statement to that effect. As in so many other cases, these differences are hardly more than in regional forms of the same species. Hollos considers C. elata a variety of C. saccata. The two Canadian plants entered below are like each other in every particular except that the capillitium in one plant was unbranched, in the other freely branched. In both plants the capillitium was less fragmented than in other specimens we have seen. One of the plants had previously been sent to Lloyd and determined by him as C. saccala. This species is in the cranijormis group, and seems nearest that species. It differs in smaller size, a proportionately longer stem, darker color of mature gleba, and in larger and minutely roughened spores. It seems also near L. muscorum and in certain respects resembles L. gemmation. See these species for further discussion. 66 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Illustrations: Hollos.

Fries Plate 112 Peridium subglobose to flattened, plicate below, the base pinched to a small point which is lightly attached by white mycelium, 2.5-5 cm. broad; cortex conspicuous, white then buffy to ochraceous, composed of a continuous coat which consists above of thick compound warts with connivent tips, becoming smoother downward and fading to a mealy furfurescence below, or in some cases much smoother above and resembling the smoother forms of Scleroderma aurantium; in all cases cracking into irregular areas or groups of warts much as in Lycoperdon marginatum and falling away by degrees to expose the thin, shining, silvery brown to chocolate colored inner peridium which falls away in flakes from above downward. Gleba passing through golden olive to chocolate brown, the subgleba small, chocolate brown or the basal part white, the chambers obvious, but not large. Spores (of plant from Lapland) spherical, greenish yellow under the microscope, minutely but distinctly warted, the warts embedded in a hyaline coat, 4.2-5.5/^, rarely 6.8ju, with one strong oil drop and sometimes a mucro. Capillitium threads fragmented, color of spores, often wavy, rarely branched, much pitted, 3-7ju thick. This arctic species is strongly characterized by its thick, deciduous cortex and purplish brown gleba. It was first described from Bellot Island, and has since been reported from Lapland by Th. C. E. Fries (as C. borealis; Zur Kenntnis der Gastero- myceten flora in Torne Lappmark, p. 238. 1914) and from Herschel Island, Kay Point, Mackenzie River Delta, and Bernard Harbor by Mr. John Dearness (Rept. Canadian Arctic Exp. 1913-18, 4, Part C: 17. 1923). We have two good collections from Lapland made by us in 1921, and these show the variation in the cortex mentioned above. Lloyd (Myc. Notes, p. 650) suggests that C. arctica Ferdinandsen and Winge (Meddelelser om Groenland 43: 144, pi. 9. 1910; see Saccardo, Sylloge 21: 480) may be the same and in this he is followed by Fries (Arkiv f. Botanik 17, No. 9: 23. 1921). We think it very probable that this supposition will finally prove to be correct. The illustrations of C. arctica show stouter warts than are recorded for C. cretacea (up to 8 mm. thick at least in one plant) and little or no chocolate color is shown in the gleba. However, in the discussion Ferdinandsen says the gleba is "grayish chocolate- brown." The larger warts may easily be a variation within the species. The long sterigmata described in C. arctica are a remarkable peculiarity, but this does not > LYCOPERDACEAE 67 exclude C. crelacca, as its basidia have not been studied. Our material does not show them. Illustrations: Fries. As cited above. Lloyd. Myc. Notes, p. 650, fig. 929. Canadian Arctic. Bernard Harbor. Johansen, coll. (Dearness Herb, and U. N. C. Herb.)

Missouriense Trelease Plates 39 and 112 Plant large, up to 9 cm. thick, obovoid or top-shaped, the thick, stalk-like base rounded below and attached by fibrous strands; cortex very thin, papery, smooth, nearly glabrous to delicately furfuraceous, pale tan or grayish in color, at maturity scaling off in areas; inner peridium also thin and fragile, yellowish to reddish, the upper part cracking into plates and scaling off after the cortex peels. Subgleba occupying the stalk-like base, of honeycomb structure and quite spongy, concave above and long persistent. Gleba white, then greenish yellow or soiled ochraceous in color. Spores (of No. 538) spherical, smooth, with a distinct mucro or short pedicel, 2.8-3.9/z thick. Capillitium slightly branched, sparingly septate, walls with numerous pits, possibly holes in them which are 1-3^ in diameter, easily breaking up, usually at these pits; average thickness of main threads 3.5ju. Unlike C. cyathiformis, this species inhabits wooded places or shrubby borders of paths or walls, and is much less abundant, though not at all rare. It, too, is a palatable and valued food. It is easily distinguished by the greenish yellow rather than purple spore mass. The type in the Schweinitz Herbarium is a fine example of the species. The spores are smooth, 3.2-3.6/* thick. In referring to C. craniformis on p. 100, Hollos is confused. The L. delicatum that Lloyd says is the same as C. craniformis is evidently from the context the delicatum of Berkeley and Curtis from Pennsylvania, not of Berkeley from India, etc. (L. Berkeleyi De Toni). In his reference to L. delicatum on p. 153 of Myc. Notes, Lloyd makes the double error of confusing Morgan's treatment of what he took to be L. delicatum Berk, with the B. & C. species and further of accusing Morgan of having no conception of L. delicatum B. & C, when Morgan stated thirteen years earlier (Journ. Cin. Soc. of Nat. Hist. 12: 171. 1890) the same thing that Lloyd here announces in italics, i.e., that L. delicatum B. & C. is the same as C. craniformis. It seems well established that L. Missouriense Trelease (see Sacc. Syll. 9: p. 277) is also the same as C. craniformis, (Morgan, 1. a). For explanation of Cooke's mistake in thinking it C. lilacina see Lloyd, Myc. Notes, p. 308.

Morg. Plates 40 and 112 Plant large to very large, sterile base ample, either long and cylindrical or shorter and tapering to the pointed base; cortex a flocculent layer which is thicker above and there usually areolated into more or less prominent warts, thinner downward, but with a tendency throughout to form more or less stellate, flattish areas; color whitish, then pallid yellowish to brownish. Inner peridium thin, breaking up into fragments at the top, then downward, exposing the bright olivaceous gold to brownish olivaceous gleba, which is very fragile and powdery. Sterile base persistent, up to 9.5 cm. thick and 10 cm. high, furrowed below and pinched to a point; the chambers of the subgleba distinct, empty and moderately large, extending up the sides for several centimeters as a tapering margin to the cup. Spores (of the plant from Pawling, New York) spherical, smooth, with a short mucro and distinct oil drop, 3.8-4.5ix. Capillitium threads up to 17/* thick, usually 7— 11/i, somewhat branched, easily breaking up at maturity; walls with narrow (about lfi wide), linear, sinuous pits. This is a northern and middle western species and so far as we know has not been collected in the southeastern states. Specimens we have seen are from New York and Canada. Curtis reports Lye. caelatum from this state (Cat'l., p. 110), but there is no reason to think that his plant was correctly determined. Calvatia caelata is not rep- resented in his herbarium, but C. craniformis, which he does not report, is found there under the name of L. delicatum B. & C. The species is well marked and very easily recognized by the fibrous or flocculent covering, separated into warts or stellate areas, and by the very characteristic thick capillitium with its conspicuous, linear pits. For treatment of this species see Morgan, Journ. Cin. Soc. Nat. Hist. 12: 169; also Lloyd, Myc. Notes, p. 166 and Lycoperd. Austr., p. 35. Lloyd's magnified figure of the cortex is good. The plant is most like C. craniformis in size, shape, and color of gleba, and in the northern states it seems largely to take the place of that species; in the south C. crani- formis is very common, while in the north it is certainly rare. Cunningham gives the following list of synonyms for this species: L. Fontanesii Dur. et Mont.; L.favosum Bon.; L. Sinclair ii Berk.; C. favosa (Bon.) Lloyd. (Trans. N. Z. Inst. 57: 190. 1926.)

Plants comparatively small, globose, obovoid, top-shaped or pyriform; the base in nearly all of our species filled with a sterile, honeycomb tissue (subgleba); cortex some- times smooth but usually composed of a coat of spines, scales, warts, or scurf, the spines frequently converging at their apices to form stellate groups. Inner peridium thin, papery and flaccid, opening by a definite apical mouth and collapsing more or less as the spores escape. Gleba composed of minute chambers which are lined with the hyme- nium, white when young, changing as the plant ripens through yellowish or olive to brown or purplish. Capillitium well developed, composed of long, branched or un- branched interwoven threads which are continuous with the inner peridium and the subgleba. From the center of the subgleba the threads may extend upward in such a thick fascicle as to form a more or less conspicuous column called the columella. Sub- gleba in most species obvious and "cellular" in structure, that is, composed of small or rather large empty chambers. Spores globose or rarely elliptical, commonly warted or spiny, in most species with a short or long pedicel. Basidia short and plump with four slender, apical sterigmata that are usually of unequal length (2-3-spored forms are said to occur). In L. polymorphum, the subgleba is not cellular but formed of homogeneous tissue. In L. pusillum it is lacking. In some species a distinct homogeneous diaphragm very similar in structure to the inner peridium separates the subgleba from the fertile tissue; in other cases the two may merge imperceptibly into each other. For the develop- ment of Lycoperdon depression in the diaphragm group, see Rabinowitsch (I.e.); for the group without diaphragm, see Bonorden. In his paper on the development of L. depressum (1. c.) Cunningham says: "About the time of the commencement of the breaking-up of the tramal plates, hyphae from the endoperidium (of the capillitium type, being thick-walled and spar- ingly branched) grow out from the endoperidium into the cavity of the gleba, following for the most part the inner portions of the glebal plates. They develop in large numbers, so that soon the whole cavity of the gleba becomes filled with them." Though he does not say so in so many words, it is evident that he means that these are the capillitium threads and that such is their origin. So far as we know this has not been brought out before. As to the cytology, he finds that the cells of the fruit body 70 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA are probably binucleate, that there is a nuclear fusion followed by two divisions in the basidium, one going into each of the spores and there dividing, so that the mature spores are binucleate. A genus of numerous species of small plants that grow on earth or rotten wood, or rarely on moss or the bark of living trees. Unless found in large groups, which often happens with L. pyriforme, the plants are too small to be of much value as food. In addition to the species treated, L. muscorum, which Hollos thinks is the same as L. pseudoradicans Lloyd, should be found here in dense moss beds, as Lloyd's plant has been collected in Virginia. In a group by itself is the very remarkable Lycoperdon sculptum found by Harkness in the mountains of California. It is covered with massive pyramidal warts up to 4 cm. broad and 3 cm. high (see Bull. Cal. Acad. Sci. 3 : 160, pi. 1. 1885). Literature Bambeke.

Subgleba large, occupying a third or sometimes nearly a half of the body. Surface light tan, 72 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA turning brownish tan, covered with very delicate, hairlike spicules and granules with the spicule tips usually free from each other. These are quite persistent but in old plants are partly worn away at the top, thus exposing the light brownish gray shining surface below. When the plants are exposed to the weather after maturity the granules and spicules may be worn away over the entire plant, leaving it perfectly smooth, as in our No. 3230. Pore apical and small. Spores (of No. 498) deep smoky purple when fully mature (but apparently going through an olivaceous stage which may be found in herbaria, with the possibility of confusion as to the real spore color), spherical, 4.4-5.5// thick (counting spines) , covered with small blunt spines about 1m long, pedicellate, the greater length of the pedicels being broken off and intermixed with the spores, the part remaining attached to a spore about half as long as the diameter of the spore. Capillitium composed of long, brown, unpitted, branched fibers attenuated at the ends and about 5-7. 5/u thick in the larger parts. The typical form of this species as described above seems to run into forms ap- proaching L. echinatum with longer, stellate spines, and Peck treated the latter as var stellate of atropurpureum.

Plates 45 and 112 Plants about 2.5-4 cm. broad not counting the spines, usually flattened, the base pinched to a slender root; cortex of long (2-5 mm.) fascicled spines, with the tapering points approximated; when young creamy white, in age deep brown and falling off, leaving the shining, light or dark brown inner peridium reticulated with minute scurfy particles. Gleba purplish brown to dull brown; subgleba small, with very small chambers, brown to golden. Odor in drying like that of old ham. Spores (of No. 7421) spherical, distinctly and rather regularly warted, with hyaline material between the warts, 4.8-6/*, often with long pedicels attached but these are usually broken off. Capillitium threads up to 7/t thick, rarely or rather frequently branched, set with rather numerous knobs, pitted, slightly sinuous and irregular. The species seems to be confined to deciduous woods and is apparently rare in this section. It was not reported from North Carolina by Schweinitz or Curtis. In addition to our Chapel Hill plants, we have examined plants from Asheville, N. C, and from Wisconsin, and plants from Scarboro, England (New York Botanical Garden), 74 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA also plants from Watlington, England, from Denmark, and from France. These last three were kindly furnished by Kew Gardens, Romeh, and Patouillard, respectively. The spines vary considerably in length and delicacy : in our No. 7421 they are much longer than in the Asheville plants or in any others we have seen. The spines of the European plants are much shorter than in the Chapel Hill ones, and are stouter than in any American specimen met with. Lloyd also notes the more slender spines of the American form (Myc. Notes, p. 208). When the spines of our plants were fresh they also were stout below, but in drying they shrank greatly. The spores of the plant from Scarboro (Massee, coll.) are distinctly warted, 4.2-5. &fi; those of the plant from Montmorency, France, 4.2-6. 2/j, with a distinct oil drop; those of the Asheville plants, 4.2-5. 5/i thick with pedicels usually broken off but sometimes with long ones present. In regard to L. echinatum, Romell writes that since Fries gives the spores of the plant from Denmark as "6-7^" thick, he thought it might be different, but on receiving a Denmark plant from Rostrup he found the spores to be no larger than in other speci- mens, for example, one from Persoon's herbarium which were 4.5-6/*. These measure- ments we can confirm for the Rostrup plant, which is the one sent us by Romell. The gleba color and the spore characters are about the same as in L. pulcherrimum, but from that the present species is easily separated by the dark brown to blackish spines at maturity, and the paler color and reticulated surface of the inner peridium when the spines fall off, the reticulations being due to the minute granular particles left around the bases of each fascicle of spines. Lycoperdon echinatum has also a strong tendency to a more flattened shape. The color of the immature plant has rarely been noted. Rea says that the young plants are white. In our collection the spines on the basal hah of freshly opened plants were pale creamy brown at the tips, cream colored at the base, and those at the very top dark brown. There is an odd contrast in the color changes in the present species and in L. pulcherrimum. Both are light colored when young; in the last species as the plants mature, the inner peridium soon becomes deep brown long before the spines fall off, the bases of the spines in some areas becoming brown at times, but the tips remaining white. In L. echinatum the opposite is the case, the tips of the spines soon become brown, the bases and inner peridium remaining cream colored, in fact the peridium remains cream colored for some little time after the spines fall off, turning brown gradually on exposure, in some cases remaining very pale. The scurfy dots that later form the reticulum are deep brown even in young stages. Peck seems to have treated the present species as L. atropurpureum var. stellare, as shown by a plant so determined by him at the New York Botanical Garden. A good collection from New Zealand, labelled L. echinatum (gift of Mr. G. H. Cunningham), looks exactly like our plants, but has distinctly smaller spores (3.5-4/x thick) and less warted than in ours. Lycoperdon compactum Cun. is a New Zealand species with similarly reticulated peridium, but differing otherwise (Lycoperdaceae, etc., p. 195). Illustrations: Dufour.

Plates 41, 46, 47 and 112 Plants 1-5 cm., generally 2-3 cm. broad, depressed-globose, conspicuously plicate below and narrowing quickly to a slender pointed root. Cortex light gray at first, turning a deeper gray and often in age with reddish brown colors. Almost as smooth as kid at first, but sooner or later the cortex becomes minutely dotted and cracked and in age wears away irregularly and incompletely as very thin scales. When young the surface may appear minutely fibrous-granular or almost completely smooth. In exposed areas the inner peridium is seen to be smooth and shining, brownish gray and often tinted with the spore color. Gleba changing from light yellow to gray, purplish gray and then deep ferruginous brown or chocolate brown (auburn to chestnut brown of Ridgway). Subgleba small, occupying only the lower fifth or sixth of the plant and composed of large papery cells. When fully grown but still immature plants are cut, water exudes from the surcharged peridium and escapes as drops, and this excess water often water-soaks areas of the surface when the plants are brought in to dry; in these respects behaving exactly like Bovistella radicata, which it further resembles in the long pedicellate spores. Lloyd does not place this species in Bovistella, but it would seem to belong there if his extension of the genus is adopted. Spores (of Xo. 715) when mature a deep chocolate brown with faint tint of purple, globose, covered with warts embedded in a clear, amorphous substance, some of the warts extending slightly beyond this substance, giving the appearance of an outer wall with radial pits, 5.5-6.8// thick, with one conspicuous oil drop and a stalk about twice, or rarely nearly thrice, the length of the spore diameter. Frequently the stalk is broken off. When KOH is applied the clear material surrounding the spore swells consider- ably. Capillitium of simple or moderately branched, somewhat irregular and knotted threads tapering at both ends and about 4-5^ wide in middle, occasionally 7/x wide at knotted places. Rarely a short branch is observed on a thread. At a certain stage it can be seen that threads are formed from the sclerotic thickening of certain selected parts of the trama. These were not simple threads at first, but the branches that came from them did not become hard and went to pieces with the spore mass at maturity. The points where these branches joined the capillitium may be detected as knots or short stubs. Illustrations: Hollos. 1. c, pi. 18, figs. 36-38. Lloyd. Myc. Notes No. 20: pi. 56, figs. 1-9. 1905.

Lycoperdon subvelatum Lloyd Plates 41 and 112 Plant depressed-globose, 3 cm. broad and about 1.5 cm. thick in the dried state; base pinched to a short stalk, ending in a stout cord which in our one collection branches under ground to bear two fruit bodies; cortex thick, superficially areolated into appres- sed, spongy patches on a granulated membrane, the whole peeling back from the top in strips, some of which have fallen off. The inner peridium is glabrous, shining, light grayish brown, without the scales which form the conspicuous furfurescence on the denuded inner peridium of L. marginatum. Mature gleba deep brownish purple; subgleba nearly white, occupying only the stalk, the chambers obvious. Spores (of No. 7263) distinctly warted, 4.8-6// thick, furnished (in the dry state) with long pedicels up to three times the diameter of the spores, but these pedicels fall off when put into water. Capillitium threads irregular in size, wavy, encrusted in places, up to 6.5/i thick. This agrees in every respect with Lloyd's species (Myc. Notes, pp. 224 and 274). It differs from L. rimidaium in the thick, continuous cortex which peels off in pliable patches and strips. This peeling off in good sized patches recalls L. marginatum, but the resemblance between the two is entirely superficial. We have four collections of typical rimulatum from the same section of Florida, which is good evidence that the present plant is not merely a regional form of that species. Illustrations: Lloyd. Myc.

Gleba pale olivaceous then darker olivaceous brown at maturity, varying con- siderably in color in different collections. It may be Isabella color (nearly old gold) or Brussel's brown with a faint tint of purple or rarely a distinct purplish brown. Spores (of No. 679) very small, spherical, about the color of the mature gleba, 3.7-4.5/1 thick and with a short pedicel, minutely asperulate; after soaking in water appearing to have a thick, hyaline wall, the spines showing as darker strialions in the hyaline material. Capillitium threads more or less uneven, with numerous or scattered distinct pits in the walls, frequently branched, tapering to a point, averaging about 3.9-4.3ju in the larger threads, in places rarely up to 7/i thick. Our collections have been compared with a good plant of L. umbrinum from Bresa- dola's herbarium (labelled L. hirtum). The spinules on the top of this specimen are somewhat larger than on any American plant we have seen, but otherwise the differ- ences are trivial The spores are minutely but distinctly warted, 4-5.5/1, rarely with a mucro; capillitium threads knobbed and strongly pitted. Our plants also agree well with descriptions of L. glabellum by Peck and Morgan except that the spore color is given as purplish brown and the spores as described are too large. However, we have examined a plant from the type locality (West Albany), collected by Peck and possibly a part of the type, and find that it agrees in these spore details and not with published descriptions. Peck gives the spores as purplish brown, 5.1-6.3/x thick, but in his plant we find them to be brown with little or no purplish tint and 4-4.8/1 thick, including warts. Peck's specimen agrees further in showing the distinct pits in the capillitium, a character that we find most useful in determining this species. The threads are also of the same thickness and irregularity, up to 4.2/1 thick. We cannot find any good difference between the present species and L. Turneri as treated by Morgan (1. c, p. 17) and Lloyd (Myc. Notes, p. 236). The original description of L. Tumcri E. & E. (Journ. Myc. 1: 87. 1885) was unfortunately based on two different lots of plants, one, the true type from Labrador, and another smaller and different plant from the eastern United States. This last we cannot dis- tinguish from L. glabellum. The type from Labrador is represented in the New York Botanical Garden and is a larger plant with much larger and rougher spores and with the capillitium threads unpitted (see pi. 113, figs. 4 and 5). One supposed difference between L. glabellum and L. Turneri is the purplish spores of the former, but this does not hold, as most specimens of L. glabellum found in herbaria, including some of Peck's own, as stated above, have brown to olivaceous gleba. Lloyd considers L. glabellum a synonym of L. umbrinum (Myc. Notes, p. 225), while Hollos treats it as a variety. The species is treated as L. glabellum by Morgan (1. c, 14: 10). Lloyd thinks that L. elegans Morgan is the same. This is the plant determined by Ellis as L. molle Pers., and Lloyd also considers the latter the same as L. glabellum (Myc. Notes, p. 209). In a plant of L. molle from the Persoon Herbarium, now at the New York Botanical Garden, the gleba is Isabella color and the spores 3.4-3.

Plates 49 and 113 Plants very small, 3-9 mm., shaped like an inverted top or long, pointed egg, with a small apical pore in age; cortex composed of a thin, spongy or granular scurf which very slowly wears away exposing the dull inner peridium or in rare cases the cortex may as- sume the form of short fascicled spines up to 1 mm. long above (as in plants from Cin- cinnati and Newfield entered below) ; color whitish or pale tan, inner peridium yellowish to gray or pale gray-brown in color. The entire peridium wall is very thin and delicate. Gleba pale brown with a slight olivaceous tint. Subgleba none. Spores (of No. 680) pale olivaceous, then dirty gray, globular, 3.3-4a< thick, smooth, walls fairly thick, a large oil drop and a short mucro. Capillitium simple, about the color of the spores, up to 10.8^ in diameter, averaging about 5.5-6^. This is the smallest known puff ball and it is remarkable in its habit of growing on mossy places on the bark of living tree trunks at some distance (usually 4-15 feet) from the ground. Others give the habitat as on old logs or around the mossy bases of living trees, but with us it always grows on living trunks. We have never found it near the ground. It has exactly the same habits and preferences for cold weather that Geaster leptospermus shows, and may often be found associated with it. This is the same as L. leprosum in the sense of Ravenel, Peck, and others, as shown by plants from their herbaria. The capillitium of Peck's plants shows slight branching, whereas in our plants it is simple or very rarely branched, agreeing with Lloyd's description. PLATE 46 JO I •* Lycoperdon rimllatum.

The apical pore is very slow to form, often taking three weeks or a month to appear after full size is reached. The plants are con- nected with the wood and with each other by conspicuous, pure white strands of my- celium. Gleba changing through greenish yellow to deep olive-brown at maturity; subgleba rather small, occupying only the constricted base, the chambers very small. Spores spherical, smooth, with a large oil drop, deep olive-brown when fully mature, 3.3-4.3/* in diameter. Capillitium branched, brownish olivaceous, main threads from 3.5-5.5^ in diameter, averaging about 3.7/z, tapering to the tips. The spores and capillitium of our plants have been compared with those of Peck's collections, and were found to agree. The species is often found in immense quantities on rotten logs and stumps and rarely in the ground. The entire plant is very persistent and after maturing in the fall may pass the winter with little change, and be found in good condition in the spring. It is edible and when found is abundant enough to be of use. Illustrations: Dufour. Atlas des Champ. Comest. et Yen., pi. 74, No. 170. 1891. Gillet. Champ. Fr. (Gasteromycetes), pi. 14. Hard.

Lycoperdon subincarnatum Peck Plates 51, 57 and 113 Plants small, about 1-2.5 cm. thick, depressed-globose, almost or quite sessile, growing on logs or stumps and attached by byssoid strands; color when young reddish brown, at maturity becoming dark brown or dull leather brown; covered with minute, separate, brown warts or with little pointed spines in groups with united tips, their bases connected by a smooth thin tissue of the same color; after full maturity these warts or spines and tissue slowly wearing away and leaving exposed the paler brown, dull inner peridium, which is very firm and tough and is marked all over with small pits outlined by acute ridges, appearing under a lens exactly like a thimble. This re- ticulated surface is assumed after maturity, in any case, whether the outer peridium falls away or not and is obvious through the outer peridium which accommodates itself to it. Subgleba scanty or practically absent, composed of small pale chambers. Gleba peculiar in the distinctly radiating tramal plates which, before maturity, give a section very much the appearance of a Geaster; color at maturity grayish purple. In some specimens there is a very distinct columella, thus increasing the resemblance to Geaster. Spores (of No. 3171a) dull brown, spherical, when dry appearing distinctly warted, when in water appearing spiny under high power, 3.8-5/i thick, counting the spines. Capillitium of long, simple or sparingly branched, very pale threads (much paler than the spores) up to 6.5ju thick, the walls irregularly thickened in places, some- times closing the lumen. This species is a strongly marked one and is easily distinguished by the small deep pits, growth on wood, sessile habit and peculiar capillitium. In most of our collections PLATE 48 J 4 *■&& Lycoperdox OMBBINUM. No. 1004 [above] ; Xo. 679 [below] LYCOPERDACEAE 81 the peridium is much more rigid and leathery than in most puffballs, but in our No. 3171a from Chapel Hill it is more pliable, though still thick and leathery. In this lot too, the outer peridium is more scurfy than warty and has not become at all worn off though the plants are old, and the spores have slightly longer spines. The surface has, however, assumed the pitted appearance in about the same fashion as other lots. All other characters are the same. Illustrations: Cunningham. Proc. Linn. Soc. N. S.

Lycoperdon muscorum Morgan L. pseudoradicans Lloyd L. polytrichum Lloyd Plates 45 and 113 We copy the following from Morgan's original description (Journ. Cin. Soc. Nat. Hist. 14: 16. 1891): "Peridium turbinate, globose or depressed-globose above, contracted below into a stem-like base, with a filamentous and fibrous mycelium. Cortex a thin white or yel- lowish coat of minute spinules with intermingled granules, which are coarser towards the apex; these wither or shrivel with age and are mostly persistent on the smooth olive-brown, shining surface of the inner peridium. Subgleba occupying little more than the stem-like base; mass of spores and capillitium greenish yellow, then brownish olivaceous; spores minutely warted, 4-4.5^ in diameter. "Growing among mosses, especially Polytrichum, in old meadows and pastures. New York, Peck. Peridium one-half to one and one-third inches in diameter and 1-3 inches in height. This is L. molle of Peck's U. S. Species of Lycoperdon." Peck calls attention to the resemblance of this plant in the immature state to Cahalia data. The mature plant is easily distinguished from the latter by the apicaJ mouth, and the average size is smaller. 82 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Dr. House has kindly sent us two plants of the type collection of L. muscorum from West Albany (Peck, as L. molle, 1. c, p. 310). The spores are spherical, minutely warted, 4^-5.5/z with a short pedicel; capillitium threads about 3-4ju thick, pitted, easily broken up. Hollos considers this the same as L. polytrichum Lloyd and L. pseudoradicans Lloyd. Lloyd states that his L. polytrichum grows only in hair cap moss, but he refers to that species a collection from Maine by Beardslee, a part of which at least was not growing in Polytrichum. Three plants of this collection seen by Lloyd and returned to Beardslee show no Polytrichum, but a much smaller moss attached, and Beardslee writes that the plants did not all grow in Polytrichum. The individual of this lot figured by Lloyd (pi. 67, fig. 7) has a moss plant attached that looks like Polytrichum. We find on examination of Beardslee's plants that the spores are like those of the type, faintly warted or many smooth, usually with a mucro, 3.8-5//, rarely 6/*; capillitium easily fragmented by slight pressure on the cover glass, pitted, often encrusted, up to 5/x thick. It is to be noted that the resemblance to Calvatia data in general appearance is further emphasized by the breaking up of the capillitium into short joints under slight pressure. This fragmentation is found in all or nearly all Calvatias. It does not occur in any other Lycoperdon we have seen. As to L. molle of Persoon, this cannot be that species, as the plant in his herbarium, which may be considered the type, has smaller spores, and according to the original description grows in oak woods. Fries says it grows in mossy fields. Illustrations: Hollos. 1. c, pi. 29, figs. 1 and 2. Lloyd. Myc.

Cortex made up of intermingled long and short terete spines or warts, the short ones being considerably more numerous than the long ones and all becoming smaller and more uniform downward and fading to scurfy granules toward the base; the color grayish tan to buff or leather color, the longer spines often darker. The large spines fall off first and leave pale smooth spots that are very obvious and characteristic; the other warts fall very slowly, if at all, and even in quite old collapsed plants only the top is free from them in areas so as to entirely expose the smooth, straw-colored inner peridium. Gleba at maturity dull ochraceous brown with a tint of olive or in some old plants brown with a tint of purple. Subgleba occupying the stem-like base which is usually a third to more than a half of the whole, its chambers up to 1 mm. wide. PLATE 49 Lycoperdon acuminatum. No. 3221 [above] Lycoperdon pyriforme. On chestnut log at Blowing Rock, N. C. [below]. Much reduced LYCOPERDACEAE 83 Spores (of Xo. 3159) color of the gleba, usually smoky brown with a tint of olive, spherical, very minutely asperulate, 3.7-4.4^ thick. Capillitium of long, spar- ingly branched, brownish threads, about 5.5/u in thickest places, tapering to about 2/j, heavily encrusted in places, frequently pitted, the color about that of the spores, ap- pearing lighter when the spores are knocked out. The plant is peculiar in the variation shown in fragility in various collections. Some are as fragile as Cahatia data, and the peridium easily breaks up into small fragments; in others the peridium is pliable and toughish as is usual in Lycoperdon. Except for the characteristic warts, the more fragile collections could easily be referred to Cahatia data. Furthermore, in some specimens of that species the capillitium does not fragment so readily as in other Calvatias. For cytological information by Maire covering this and other species, see under Sderoderma aurantium. Morgan (1. c, p. 13) treats L. perlatum as distinct, but Lloyd thinks he misunder- stood that species. Hollos considers them the same. Figures by Tulasne (Ann. Sci. Nat. 17: pi. 2, fig. 11), as L. perlatum, do not show any roughness on the spores. Under the name L. nigrescens, Lloyd treats an American plant that he considers "really a form of gemmation excepting that the stiff spines are not consolidated" (Myc. Notes, p. 229). The European plant with blacker warts he refers to on pages 212 and 338 (see his plates 47, 60, and 123), and in his last reference he considers it less like L. gemmatum than he had formerly supposed. The American plants above mentioned as L. nigrescens may be the same as those we refer to L. Peckii. It seems clear that the original L. excipuUforme Scop, is only a form of L. gemmatum, as treated by Fries and Lloyd. The name has also been applied, apparently without reason, to a form of L. pyrijorme and apparently to a form of Cahatia saccata. A European plant (Herbarium of Klotzsch), received from Ryks Herbarium at Leiden as Lycoperdon gemmatum (No. 58), has the external appearance of that plant, but is peculiar in having very small, smooth spores, 2.3-3.2/x thick. We have found one cespitose group of plants very much like this: spores nearly as small (2.8-3. 7/x) and nearly smooth (Linville Falls, No. 8221). Illustrations: Dufour. Atlas des Champ.

Toward the base the spines become more slender and hairlike and are more obviously intermingled with granular matter. Except for the lavender color of the upper half, the plant until near maturity is nearly white. Subgleba composed of rather small cells and occupying about a third of the plant. Spores (of No. 5749) olivaceous brown, spherical, 3.6-4.4/j thick, with a small oil drop and a short pedicel, the wall obscurely dotted (pitted or minutely warted) and appearing faintly striate radially in optical section; surrounding the spore is the thin hyaline layer that is found in most Lycoperdon species. Capillitium threads very slightly branched, up to 6/x thick and tapering to delicate tips. We have compared our plants with a collection in the Albany Herbarium from Forestburg, N. Y., collected and determined by Peck and find them the same in appear- ance, surface characters, spores and capillitium. The species (at least in so far as our collections go) is easily distinguished in the fresh state before maturity by the lavender color, a character not mentioned by others; in the mature and dry state it is distin- guished by the ochraceous or buff color, by compound spines with flaring bases and delicate, cohering tips, by granular matter between the spines, and by the small, dotted (not obviously warted) spores with distinct pedicels. When the spines fall away they n \ik 51 r ■■ W&* LVCOPEBDON SUBINCASNATUM. Ashcvillc, N. C. [top row], I No. 5754 [all others] LYCOPERDACEAE 85 leave smooth circular spots surrounded by minute granules, thus giving a spotted or reticulated appearance to the surface as in L. eckinatum and L. gcmmatum. According to -Morgan (Journ. Cin. Soc. Nat. Hist. 14: 15. 1891) this is the L. eckinatum of Peck's United States Species of Lycoperdon, while the true L. eckinatum is treated as L. con- stcllatum by Peck and by Trelease. In the Ellis collection at the New York Botanical Garden are plants from Peck (N. V.) labelled L. eckinatum which are L. Peckii. (See Morgan, above cited, and Lloyd, Myc. Notes, p. 223.) Lycoperdon Peckii is not recognized by Lloyd, but we cannot reconcile our plant with any other species and refer it to C. Peckii as it seems to agree well with Morgan's description and with the above-mentioned plants from Peck. To all appearances this might represent the L. nigresccns of Europe to which it might be referred except for the light color which is retained at all ages (see Lloyd, Myc. Works, pi. 123, figs. 1-6). It differs from L. eckinatum in the shorter pale spines and much smaller olivaceous spores; from L. pidcherrimum in the much shorter spines, the pale surface of the inner peridium and the smooth, olivaceous spores; from L. eximium in stouter, longer spines and the smaller, spherical spores; from L.fuscum in the paler, stouter, longer spines with granular or scurfy material between. The most important differences between the present species and L. gcmmatum, which is nearest, and of which this might be treated as only a variety, is the tapering fascicled spines with tips united, and the smooth spores. In these characters it agrees with the plants from Peck above-mentioned, which are also similar in the small, dot-like warts between the spines. As L. Peckii is described as having a smooth surface (not spotted) after the spines fall off, a divergence from our plant in this respect is indicated; Peck's specimens above-mentioned are, however, like ours. A difference in age of plants might easily account for such a discrepancy. Our oldest plants were found soon after opening and only a part of the upper surface was denuded. North Carolina.

The spines fall off singly and each carries its own area of the thin cortex, thus exposing the pale brown, smooth and shining, inner peridium which is faintly pitted or wrinkled, or in a form distinctly reticulated. Subgleba very scanty in nearly sessile forms or more obvious when there is a distinct stalk. Spores (of No. 5668) dull brown at full maturity, subspherical to short oval, 3.7— 1.8/i thick, minutely rough, furnished with a long persistent pedicel which is about 86 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 4-5 times as long as the spore. Capillitium threads up to 6.6m thick, pitted, sparsely branched, ochraceous under transmitted light. Growing in humus or on logs in deciduous woods, and apparently northern in its range except for the higher southern mountains (reported by Atkinson from Alabama). It has not before been reported from our state. The species is easily recognized by the rather long, deciduous spines, the pale, shining, inner peridium and particularly by the very characteristic smooth spores with very long persistent pedicels. Lloyd includes this species in his expansion of the genus Bovistella (Myc. Notes, p. 282), but we are not including in Bovistella plants with the capillitium of Lycoperdon. Illustrations: Hollos.

Cortex composed of slender spines about 1 mm. long which often curve and converge at the apex, and gradually decrease in length downward until they are mere granules at the base of the stalk; color tan, brownish tan or deeper brown, and in age the spines become very deep brown. After maturity the spines begin to wear away, so that in age they are reduced to granular dots, or even these may be worn off in areas, so as to expose the tan or light brown shining layer beneath. The mouth is a torn, irregular opening of rather tardy appearance. Gleba greenish yellow, then brownish olivaceous and at full maturity deep brown with a tint of purple, about bister of Ridgway. Sub- gleba of honeycomb structure, occupying all of the stalk and extending with a thin expansion to the broadest part, occupying in all about one-third to one-fourth of the body. Spores (of No. 1002) purplish brown, elliptic or oval, with a thicker, clear inner wall and a darker outer wall which is dotted with minute warts, surrounded by a hyaline coat, distinctly stalked, 4.3-5 x 5-6. 5m. Capillitium of long, sparingly branched, deep brown threads that are almost the diameter of the spores, and taper to slender tips. Recognized by its densely set, regular spines, dark color in age and rather large oval spores. It does not seem to have been reported from this state before, and has been known only from South Carolina and Alabama. The species is described by Morgan as having brownish olivaceous spores, but in our fully mature plants with open mouths the spores are deep purplish brown. Only a slight difference in maturity would make this difference in color. Illustrations: Lloyd. Myc. Works, pi. 59, figs. 6-8. Morgan. Journ. Cin. Soc. Nat. Hist. 14: pi. 2, fig. 3. 1002.

Subgleba small, in the pres- ent form occupying only about a sixth of the body, in one form nearly absent (see below) ; chambers of moderate size. Spores (of No. 5525) dusky olivaceous, spherical, 4-4.8m thick, distinctly dotted with warts which project through the hyaline coat. Capillitium threads slightly branched, up to 3.7m thick, with thick, pitted walls. The plant described above is the dark-colored, often large form with dark brown inner peridium and persistent spinules. We also have the form known as L. dryinum and one approaching the form L. cupricum. The former is a small plant with very short black spinules, silvery brown inner peridium, and little or no subgleba (No. 5777). The latter is a plant of moderate size with slender, rather scattered, black spinules and a golden brown to coppery brown inner peridium (No. 5719). All forms are separated from related species by the very slender spines which soon turn dark brown to black and which are so openly placed as to clearly show the smooth surface of the inner per- idium between them. These spines are the only covering of the inner peridium and are not intermingled with scurfy or granular material. The resulting appearance in the fresh plant is remarkably like that of a baby's head, set with thin dark hair. All forms grow in deciduous woods on leaves or rotting wood.

Plates 55, 56 and 113 Plants 1.2-4.5 cm. broad and nearly always broader than tall; narrowing below to a short stem and root. Cortex pure white, then a little discolored or pinkish, becoming clay colored or deep brown in age, composed of densely set, sharp, erect warts which are 88 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA short, thick and simple or more slender and fascicled with their tips cohering, at matur- ity breaking up into large or small flakes (see below), usually beginning in a median line between the stem and top, but often rupturing at every point or at many points at once (see below for woods form). The lower third, covering the stem and lower part of the body, does not fall away. Inner peridium strong to pale olivaceous brown when first exposed, even, or in one of our collections (Warrenton, Va.) obviously pitted, much as in gemmatum. It is peculiar in having beneath the spines a covering of a minute brown furfurescence which disappears rather slowly and leaves the surface paler and shining. This furfurescence is different from that of any other plant we know. It is composed of little flat scales, the prevailing shape of which is spherical to oblong, vary- ing to irregular and angled, the majority elongated and up to 60 x IOO/j. Subgleba ample, composed of distinct, rather large compartments, occupying the stem and lower part of the body and persistent after the top has disappeared, remaining as a dark brown pedicel with a thin, collapsed margin. Spores (of No. 482) spherical, smooth, 3.6-4. lju thick, with one oil drop. The spores have mixed with them about an equal number of small rods like bacilli, that average about twice the length of the spore's width. Basidia (of No. 5225) 6.6-7.4,u thick, usually 4-spored. Capillitium composed of yellowish brown fibers very little branched, about as thick as the spores as a rule, but up to 5/x in diameter, attenuated at the ends. The spores and capillitium of our plants have been compared with Peck's collec- tions of separans and are the same. One of the most characteristic qualities of the plant is its strong odor when ripening or fading like that of horse urine, a distinction it shares with L. gemmatum. It is a very common plant with us in open places and cultivated ground, and less often in woods. The spines are very variable, in some cases very thick and short and not split up into fascicles, in others slender and moderately short or long, and in groups of several with their tips united. In Chapel Hill there are two rather distinct forms; in one (typical) of cultivated or open ground the cortex falls off in larger flakes and more irregularly and the spores have a little mucro left after the pedicel breaks off; in the other one of woods each group of spines with its underlying tissue is apt to fall off singly or with a small group of others, and the denudation is more regular, proceeding from the top downward. In this form the spores have no mucro. The scales on the denuded surface are just like those of the typical form. This character alone is sufficient to distinguish the species. For general discussion of the species see Lloyd (Myc. Notes, pp. 214 and 231). It seems certain that L. cruciatum is L. marginatum, as Rostkovius's good figure could not be referred to anything else. Spores of three specimens labelled cruciatum in Bresadola's herbarium (sent by Romell) are not those of the present species. This is true also of a specimen labelled marginatum in the same herbarium We have seen European material of true L. marginatum, as L. cruciatum (Herb. Hasskarl & Herb. Klotzsch), received from the Ryks Herbarium in Leiden. They show the same spores and peridial scales as in our specimens (spores 3. 6-4. 5m). The capillitium is not color- less but of about the same tint as in ours. We have compared capillitium of plants just maturing in our No. 482 with other mature ones of the same collection and find that the capillitium does not change after the spores are mature. A bit of the inner peridium and spores and capillitium of L. cahescens B. & C. from the Curtis Herbarium (Wright, No. 6366, co-type), kindly sent us by Dr. Thaxter, shows it to be marginatum. The peridial scales and the spores are the same as in the typical form of L. marginatum. Lycopcrdon pratense Pers. is also considered a synonym -t w < _ -a c o 2; s 3 >• J LYCOPERDACEAE 89 by Hollos, but Lloyd thinks that the typical pratense docs not occur in the United States. A specimen from New Zealand determined as L. praiaisc by Lloyd docs not look like our L. marginatum, as the spines are much shorter and the denuded pcridium shows no obvious furfurescence. The spores are slightly smaller and both they and the capillitium are paler than in our plants. From the description and illustration, L. abscission R. E. Fries from Bolivia and Argentina is nearest L. marginatum. It is remarkable in the comparatively large size of the subgleba which occupies most of the fruit body. Illustrations: Hani.

With age these fall away in part from the top of the plant, but the powdery scurf between them wears away more slowly so that the pale brown inner peridium becomes very tardily smooth. Gleba greenish yellow, then light brownish yellow to brown with a tint of olive. Subgleba quite small but distinct, the compartments of moderate size. Spores (of No. 552) small, spherical, minutely asperulate, 2.6-3.7ju in diameter, averaging about 3.3,u. Capillitium of almost hyaline, sparingly branched, flaccid, septate threads, 3-7// in diameter, averaging about twice the diameter of the spores. This little plant has almost the external appearance when immature of L. margi- natum, but averages much smaller and also differs in a strong tendency to crowded growth. The cortex does not flake off as in L. marginatum, but this difference cannot be made out until full maturity. The plants of No. 539 were thought at first to be L. marginatum and were watched for two weeks. As no cracking occurred they were brought in and found to differ from L. marginatum in the color of the spores and the character of the capillitium. In the herbarium at Albany some of Peck's collections labelled L. Wrightii are L. marginatum. As Morgan points out (as L. Curtisii), the thin-walled, collapsing capillitium is a peculiar character. We have examined the co-type of L. Curtisii No. 197 and find the spores to be spherical, minutely rough, 3-3. 7/i thick. Morgan treats both L. Wrightii and L. Curtisii, the latter being the plant as we have it. What plant Morgan treated as L. Wrightii we do not know (see Lloyd, Myc. Notes, p. 153). Lycoperdon Wrightii is in reality a synonym of the present species, as shown by the co-type in the Curtis Herbarium (Wright, No. 7; Curtis, No. 5633). The spores are spherical, minutely warted, 3-3. 6/x thick. Another collection so labelled in the Curtis Herbarium from New York (Peck) looks like L. pusillum, while still another from New Jersey (Austin) looks like L. marginatum (L. cruciatum), as Lloyd says (Myc. Notes, p. 153). For the distribution of this species see R. E. Fries, I.e., p. 8. We have examined a specimen of L. candidum Pers. from Persoon's herbarium, kindly sent us by Miss Cool. The appearance of the cortex is like that of L. Curtisii, and the spores agree in size (3-3. 8/x) but run smoother (pi. 113, fig. 23). The plant seems to be not quite mature, and this may account for the difference. The Lye. candidum of Schweinitz Herbarium as represented in the Michener Herb. (No. 2747) is Bovista plumbea. Lycoperdon candidum (Rostk.) Bon. is a different plant, now put under Cahatia. Illustrations: Hard. Mushrooms, fig. 468 (as L. Wrightii). Lloyd. Myc. Works, pi. 63, figs. 1^1 (as L. Wrightii).

Capillitium threads long, delicate, branched, up to 6.5/z thick, considerably pitted in places. This little plant was originally described from Cuba, and is quite rare in this country, only a few scattered collections having been noted before and none from this state. However, it agrees so well with the descriptions of both Morgan and Lloyd for this species that we feel quite sure our determination is correct. The plants look like Lloyd's figures, and the spores are shaped like those shown on his plate 65, figs. 9-12. The species shades into L. pusillum by intermediate forms. We are entering No. 5312 as this species on the ground of its absolutely smooth spores that are not perfectly spherical. Xo. 5211, which we are entering under L. pusillum, is also intermediate.

Color when young pure white, then clay color or dull olivaceous yellow, and often dark brown in age. Gleba passing through yellow to greenish yellow, becoming at full maturity brownish olive or grayish olive-brown to deep coffee-brown without a tint of olive, filling the entire peridium; that is, there is no subgleba. The peridium before maturity is thick, up to 15 mm., but rapidly becomes extremely thin as it dries during 92 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA maturation. There is no breaking away of a superficial part. At maturity a small apical pore is formed. Spores color of the gleba, spherical, 3.2-4.3/j. thick, with rather thick wall, a distinct, small mucro and a large oil drop, quite smooth in some plants, in others with the walls faintly warted or pitted, appearing radially striate. Outside of the main brownish wall a faint hyaline coat may be seen under high power. Basidia (of No. 5211) short- clavate, stout, 4.5-5.5 x 9-1 In, with 4 or in many cases only 2 long sterigmata visible at one time. CapiHitium color of the gleba and composed of long, delicate, branched threads that are attenuated at the ends and are about the width of the spores, some up to 6.5^i thick; walls more or less pitted, the larger threads usually more pitted than the smaller ones. This is a rather common little plant in Chapel Hill in open places, fields and yards. It is a puzzling species due to variation in the spores which is not associated with any other character we can make out, such as size, subgleba or surface. The capillitium is the same in all. None of our plants has a subgleba. Some collections that we are retaining in L. pusillum are intermediate between that and L. oblongisporum, as No. 5211, which has spores that are mostly oval and pointed toward the mucro, smooth to very minutely punctate. 98.

Other characters agree well with the above. It is supposed bv some authors, as Hollos, that /.. poly- morph urn is the same as L.furfuraccuni SchaelT., a species which is insufficiently known.

Until dulled by maturity, this striking plant is by far the most brilliant of our puffballs. No description by others suggests the brilliant orange of our mountain plant, though Peck speaks of the species as conspicuous. While the plant may be only a form of L. polymorphum, it is so conspicuous and distinctive in itself that it will do no harm to retain Peck's name for it. In the mountains of western North Carolina, L. piisillum grows in pastures, and L. coloratum in the woods. They are strikingly different. Illustrations: ? Morgan. Journ. Cin. Soc. Nat.

BOVISTELLA Morgan Plants subglobose and permanently attached by a rooting base; inner peridium thin, flaccid, opening by a definite, apical pore, and collapsing as the spores escape; capillitium as in Bovista, of distinct units with all the ends tapering and not connected with the peridium; but in some cases very slender and not abundantly branched; spores oval or subglobose, smooth (at least in American species), and with long pedicels. Separated from Lycoperdon by the discrete, branched units of the capillitium; from Calvatia by this character and by the torn mouth ; and from Bovista by the col- lapsing inner peridium, and by the permanent attachment to the soil. The above is essentially the conception of the genus by Morgan who established it (see below), except that we are including species without a sterile base, as does Lloyd. We are not following Lloyd in including plants with long, intertwined capillitium fibers which arise from the periphery as in Lycoperdon. Without this character we would not know how to separate the latter. Lloyd would extend the limits of the genus as follows (Myc. Notes No. 23: 277. 1906). "Peridium flaccid, with or without a sterile base, opening by a definite mouth. Capillitium of short, separate threads or long, intertwined threads. Spores pedicel- late." Note that the flaccid peridium is the only character in this definition that would exclude species of Bovista. However, in his discussion, Lloyd makes the further dis- tinction of the breaking away from the base in Bovista and the permanent attachment of Lycoperdae, including Bovistella. He says that frequently the characteristic capillitium and pedicellate spores are associated in the same plant, but not always, and he would "embrace in the genus Bovistella all plants of the tribe Lycoperdae that have either or both of these characters." in w < a. ^SS9»*S o o LYCOPERDACEAE 95 Literature Cunningham.

Plates 59 and 114 Plants globose or broadly top-shaped, up to 7 cm. broad usually, but rarely as large as 14.5 cm., often plicate below; attached by a firm, thick, tapering root; cortex com- posed over the upper half or more of soft, pyramidal warts which are often fused at their tips into fascicles as in species of Lycoperdon, these fading towards the base to a dense soft scurf; white at first, then dull ochraceous when dry and wearing away ir- regularly and incompletely to expose the thin, papery, inner peridium which is metallic buff or silvery buff or ochraceous in color, rupturing at maturity by an apical pore or slit which extends by fission on exposure and finally by collapsing and incurling leaves the entire subgleba exposed in age. Subgleba large, broad, occupying about one- third to one-half the plant, the edges extending up the sides of the peridium to form a cup- shaped base which is long persistent. Gleba at first white and cheesy, then passing through yellowish to brown (about Brussels brown of Ridgway) ; chambers of the young gleba 25-250^ wide, hollow. Before ripening begins, a section of the peridium shows that the scurfy and warty superficial coat is an extension of a thick, compact, pulpy, tender layer about 450,u thick of bladdery cells beneath which lies the thin, very tough inner peridium about 130m thick, composed of densely woven, slender filaments about 3.7/i thick. Spores oval, smooth, 3.5-4.5 x 4.3-5. 2ju, with one large oil drop and long, hyaline, persistent pedicels which average about 11m long. Basidia short, 6.6/u thick, with 4 long sterigmata which break off with the spores. Capillitium threads free, short, 3-5 times branched, the main stem 7-12/x thick, the branches tapering to about 3.5/x thick near the ends. At Hartsville, S. C. (see below), we have collected a very robust form reaching 14.5 cm. broad, which is considerably larger than the form figured by Lloyd (cited below). The species is common in Chapel Hill and prefers cultivated soil and open places. When quite fresh and white the taste is sweetish and pleasant and the odor slight, but as the color begins to change the odor becomes rather strong and nitrous. As represented in Torrend's Fungi Selecti Exs. No. 77, Bovista radicata is the same as our plant and confirms Patouillard's conclusion (accepted by Hollos) that our Ameri- can plant is B. radicata. The type was described from northern Africa (Syll. Crypt., etc., Paris, 1856). Plants from California distributed by McClatchie as B. ammophila Lev., a European species, now included in Bovistella, are considered by Lloyd as B. plumbea (Myc. Notes, p. 88). 96 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Illustrations: Hard. Mushrooms, fig. 473. Lloyd. Myc. Works, pi. 86. Marshall. Mushroom Book, pi. opposite p. 128. 79.

Capillitium of separate units, but threads long and slender and less frequently branched than in most species of this genus or of Bovista; main threads about 5.5// thick. This little species has been collected in a number of widely separated places. The original collection was from Ecuador, and we have specimens from North Dakota and Lapland. Dr. R. E. Fries has also reported it from Lapland, and Lloyd reports it from Michigan. This last is the only record, so far as we know, from the eastern United States. We have examined a part of the original collection from Ecuador, kindly sent us by Patouillard himself, and find it to be just like our collection from Lapland. The capil- litium is of long, slender branched units with main threads only about 6.5// thick; spores subspherical, 4-5.2 x 4.8-5.8// with slender pedicels up to 12.8// long, the walls of the spores showing faint radial lines. Patouillard describes the spores as echinulate, but we see only faint lines with no projection in optical section. Lloyd describes from Massachusetts Bovistella Davisii (Myc.

Plants spherical, attached centrally at the base, the outer peridium thin, fragile, flaking off at maturity and leaving exposed the smooth, thin, distended, metallic-looking inner peridium which opens by an apical pore, becomes detached from the ground, and is blown about like a light ball, puffing out the spores. Capillitium not connected with the peridium, but composed of separate units which branch dichotomously or irregularly and end in tapering points. There is no sterile base. Spores dark brown or purplish brown, in one of our species with a well developed pedicel. The genus is remarkable in its tumbling habit (shared by Mycenastrum and to a less extent by Disciseda*) and the inner peridium is especially adapted to this end by the retention of its shape as an inflated ball and by its firm, parchment-like, resilient tex- ture. These balls are rolled about by the wind and the spores shaken out by degrees through the apical mouth or slit. They are very durable and in mountain pastures old plants of the preceding year may still be found in good condition. Lloyd considers B. montana Morgan the same as B. pila. Literature Bonorden.

Spores deep brown, thick-walled, smooth, spherical with a very short pedicel or mucro, 3.5-4.3/x thick. Capillitium dark purplish brown at maturity, much branched; branches long, gradually tapering to a point; main hyphae mostly about 11/u thick, rarely up to 13/u. Immature gleba white, showing very small irregular chambers under a lens; basidia (of No. 7999) short-clavate, 8-10.5 x 14— 18/x, with 4, rarely 3, unequal sterigmata 4-7. 4/i long. The co-type of B. pila in the Curtis Herbarium agrees with the usual interpretation. The spores are spherical, smooth, 3.7-4.5/x thick. This species seems to be the American representative of B. nigrescens of Europe, and Lloyd seems to be right in concluding that the latter does not occur in this country. Early records in this country, as by Schweinitz and Curtis, have since proved to be based on B. pila or B. plumbea. The two species, B. pila and B. nigrescens, can easily be distinguished by the spores (as noted by Hollos and Lloyd), the latter having somewhat oval spores with a long pedicel. (In a specimen from Bresadola, Cavelante, August, 1898, the spores are 3.8-4.8 x 4-5. 2yu, with a long tapering pedicel.) The spores of B. nigrescens (pi. 114, fig. 12) are much more like those of B. plumbea, which are oval with a long pedicel, but those of the latter that we have seen are distinctly larger. Th. Fries gives the spores of B. nigrescens as 5-6/u in diameter. If this variation exists, the plants should hardly be separated. The spores of Schweinitz's "B. nigrescens" are those of B. pila, spherical, usually sessile, sometimes with a short mucro, 3.7-4.5/j thick. Illustrations: Lloyd.

Capillitium of branched units as in its relatives; main threads up to 22^u thick, with thick walls. This rare plant was described by Morgan from Ohio and Nebraska and is doubtfully reported from Massachusetts by Lloyd. We have drawn the above description from two Canadian plants noted below and kindly sent us by Dearness. One of these plants is still covered all over with the thin sand case except for spots here and there; the other is clean of dirt, the cortex remaining only as a basal disc. This last has the inner per- idium deep red-brown, while in the former it is grayish where exposed. The spores and capillitium in both plants are identical. The thin, papery peridium would seem to indicate a close approach to the genus Bovistella. Hollos (1. c, p. 126) reduces both this species and Bovistella dealbata Lloyd (Myc. Notes, p. 86) to Bovista tomentosa (Vitt.) De Toni of Europe. We have examined an authentic specimen of Bovistella dealbata (pi. 61 and pi. 114, fig. 14) and find it quite different from the plant described above. It is an epigean species exposed throughout the entire growth of the fruit body and in this way differing sharply from what we are taking to be B. minor and also from Morgan's description of that species. The spores of the Lloyd specimen are larger than in the Dearness plants and are as Hollos said furnished with minute warts (x 2160). They are spherical to subspherical, 4.3-5.5 x 5-6. 3p (rarely 6.8//), with pedicels 6-12. Su long, usually about 8ju long. Capillitium threads up to 10/j. thick, moderately branched into long, slender, tapering branches. We have also examined a specimen of B. tomentosa from Bresadola's herbarium from Andola, collected and determined by him, and find that it agrees well with Hollos's description and figures except that the spores are practically smooth (3.5-4.2 x 4-5. 5/u). The plants are the same size as B. dealbata, but seem to be darker at all stages, the spores are somewhat smaller, and the capillitium threads are thicker and more branched. Without further evidence we prefer to keep the two species separate. As the European species is obviously epigean we cannot see how it could be Bovista minor. We have not seen an authentic specimen of the latter, but as both Morgan's (Journ. Cin. Soc. Nat. Hist. 14: 147) and Lloyd's (Myc. Notes, p. 117) descriptions agree in every respect, we use the name for the Canadian plants. Plants in the U. S. National Museum from Nevada de Toluca, Mexico, determined by Lloyd as B. brunnea Berk., are, in appearance, spores and capillitium, like those of specimens of Bovistella dealbata from the Lloyd Herbarium, sent us by Lloyd. Bovista brunnea Berk, was originally described from New Zealand, and plants from that country sent us by Cunningham under that name are distinctly olive-brown in the immature condition and otherwise look somewhat different from the others. The spores and capillitium are, however, the same. Lloyd thinks that B. brunnea is the same as B. tomentosa and not the same as B. dealbata. Illustrations: Lloyd. Myc. Works, pi. 3, figs. 3-5.

This species is abundant in the west, but rare in the eastern states. Lloyd reports it from Illinois (Myc Notes, p. 120) and from Florida (Letter 62, note 441). (See also Myc. Notes, p. 1173, where an error is corrected.) The plant much resembles a Scleroderma in general appearance, but it is easily dis- tinguished by the spiny capillitium threads. It differs also in its habit of breaking loose from its attachment when mature and adopting a tumbling habit like Bovista. The separate threads arising freely in the gleba also recall Bovista.

Plants at first subglobose and with or without an apical beak; either just buried in the soil, trash, or moss they grow in and with or without a fine flocculence all over which binds the substratum to the surface, or in some species seated on the surface of rotting wood, trash, or earth and attached only at the base (epigeal). Outer peridium at maturity splitting from the apex into few or many rays which expand more or less in a stellate way, or even recurve strongly and are composed typically of three layers, the surface one a delicate, interwoven coat of flocculence or tomentum that in some species is scarcely obvious, but in others forms a more or less perfect membrane which remains attached to the next layer on expansion, or becomes more or less detached from it, and in some cases is completely stripped off and remains as an empty sac in the ground when the rest of the plant is lifted out by the recurving lobes of the next layer. This next inner layer, called the fibrous layer, is thicker and tougher and is formed of closely woven, homogeneous fibers. Lining this layer and splitting with it is a third layer of turgid, fleshy tissue which dries out and shrinks after opening, either remaining attached to the inner side of the fibrous layer as a continuous or much cracked cartilaginous- looking membrane, or peeling off and disappearing in places or throughout. Sometimes a part is separated and remains as a kind of collar around the center. For the micro- scopic structure of peridia, see under G. velatinus. Inner peridium (spore sac) thin, tough, membranous, pliable, stalked or sessile, opening by a single, apical mouth that is simply a small torn hole or an elevated pore which may or may not be surrounded by a circular area (peristome) of different texture, and more or less sharply circumscribed outline. In one group of species this area is prettily and regularly fluted (sulcate). Gleba pure white when young, composed of tramal fibers and plates which radiate straight from the columella to the peridium, and which enclose the very narrow, much elongated, almost tubular cavities which are lined with the basidia. The glebal chambers are not visible in longitudinal section and barely so in cross section. Basidia thick, elliptic to pyriform, borne on very slender hyphae, 4-8-spored. Spores spherical or subspherical, usually warted or asperulate. Capillitium abundant, composed of simple, rarely-branched threads which arise from the walls and also from the more or less prominent (in some species vague or absent) columella. An interesting genus of numerous species that are popularly known as "earth stars." The dry spores puff out of the mouths as in puffballs, leaving the persistent capillitium behind. A peculiar, long-stalked species (G. stipitatus Solms) is recorded from Java (Fischer, Hedwigia 32 : 50, pi. 5. 1893). Before opening it has much the appearance of Lycoperdon muscorum but has a short point. Another peculiar plant should be men- tioned here, although not found in America. It is Trichaster melanocephalus from Europe. It is like a large Geaster fornicatus in general appearance except that the inner peridium wall very soon disappears. It differs also in the very large, globose, hard columella around which the capillitium forms a matted mass filled with spores. There is a specimen in Washington under the name of G. fornicatus (Myc. and Path. Herb.; Petrak, Fl. Bohemiae et Moraviae exs. No. 1498). It is just like Lloyd's figures (Myc. Notes, p. 189, pi. 17) and has all the characters of the species. The spores are about like those of fornicatus, distinctly warted, 3.8-4.5/n. The plant is said to be quite PLATK 62 Mycenastrum cojuum. Lloyd Herb, [above] Pitchfork, Wyoming [below] LYCOPERDACEAE 103 epigean, and this is borne out by the plant just mentioned, as the outer layer has not been stripped off and is furthermore free of trash. In attempting to find a natural classification for the species of Geaster, one meets with difficulties and with differences of opinion among authors. What are the char- acters expressing the most fundamental relationships; and those of lesser degrees of importance? All arrangements heretofore proposed have in certain sections obviously violated, it seems to us, the true relationships. De Toni (Rev. Mycol. 9: 64. 1887. See also Sacc. Syll. 71: 70, and Hollos, I.e., p. 51) divides the true Geasters first into a fornicate and a cupulate group (Fornicati and Cupulati) and the remaining species which are subdivided into the sulcate-striate group (Striati) and the fimbriate group (Fim- briati). As a result of the first two groupings there are thrown together the very dis- similar fomicatus and radicans, while the near relatives fomicatus and rufescens, and coroiiaius and minimus are separated. The third group is a natural one, but the last should be rearranged. Morgan's two main groups, DepeUiti and Pelliculosi, are in part natural, but are unnatural in having species with sulcate-plicate peristomes in each. His two sub- groups under DepeUiti are unnatural for the same reason. He does not make the mistake of making the hygroscopic character a leading one. In Lloyd's last outline of the Geasters (Myc. Notes, p. 317), as well as in The Geastrae, he first divides them into the Rigidae and the Xon-rigidae, the latter with six groups. This throws together such distantly related plants as mammosus and Drummondii and separates species with sulcate peristomes. Of the six groups of Lloyd's Non-rigidae, the first and last are natural in their in- clusions, though Hariotii is excluded from the first. The other three groups are in our opinion unnatural to a greater or less degree. That the hygroscopic character is not the most fundamental one seems obvious. Both hygroscopic and non-hygroscopic species are found in the very natural group with sulcate peristomes, as well as in the non- sulcate group. In related species and even in the same species at times the intensity of this character is very variable and in individuals may practically disappear. For example, in arenarius the rays while hygroscopic are usually pliable and thin, while in the very closely related floriformis they are much more rigid. In asper individuals appear rarely without any hygroscopic tendency at all, though the species is markedly hygroscopic. Within certain limits the structure of the mouth area is the most dependable character. The sulcate group is a natural one and there are no confusing intermediates connecting it with the non-sulcate group. So-called intermediates like Morganii are not troublesome, as their crumpled mouths rarely bear any real resemblance to a truly sulcate peristome. In the non-sulcate group the distinction between the definite and indefinite peristome, while adequate enough as a rule, is in some cases obscured by variation. This is particularly true in floriformis and arenarius. In constructing the key we have used the characters in the order of their importance as it seems to us, and the key is therefore as natural a grouping of the species as we can arrange at present.

Smith Plates 63 and 115 Plants large, pointed before opening, the point up to 12 mm. long, the inner perid- ium subspherical, up to 2.7 cm. thick, quite sessile, gray-brown when fresh, becoming reddish brown with age; mouth fibrillose and becoming lacerated, surrounded by a more or less definitely outlined, broadly conical area which may or may not be paler. Outer peridium splitting into 6-8 segments with long acuminate tips which expand or become revolute under the convex, flat or less often arched base; fleshy layer thick, in our plants mostly remaining intact as a moderately thick, reddish brown, cracked crust on the fibrous layer, the central region in some plants breaking loose from the part on the rays to form a broad collar or cup around the inner peridium; outer layer usually nearly free of dirt or trash, but with a few small particles sticking to any part, firm, glabrous, dull yellowish, mostly adnate, but cracking into radial strips or irregular areas; mycelium basal and leaving a scar at point of attachment when the plant is lifted ; button supposed normally to be sunk in the substratum, but its surface does not hold the trash as in G. fimbriates, G. rufescens, G. fornicatus, and most other subterranean species (for rare exception see note under Alabama entry below). Columella about 1 cm. long, clavate, and persistent. Spores (of No. 5886) deep smoky brown, distinctly warted, spherical, 3.7-4.4/u, most about 3.9/t thick. Capillitium threads unbranched, about 5,u, up to 6/j thick, not sinuous, concolorous with the spores. Geaster lageniformis, as suggested by Morgan (see Lloyd, The Geastrae, p. 38), is a small form of G. triplex. The cracked surface, definite mouth, pointed button, and spores are all the same. A typical-looking plant of G. lageniformis from London, Canada (N. Y. Bot. Gard., labelled G. saccatus), has spores distinctly verrucose, 3.5-4.2yu. Another from the same place and in the same herbarium is Ellis & Ev., N. Am. Fungi, No. 2735 (as G. triplex). Our plants are like the G. triplex of Thiimen's Mycotheca Universalis No. 1410 from Holland, which has spores distinctly papillate, 3.6-4.2,u. Plants from Hungary at the New York Botanical Garden correctly labelled G. lageniformis are the same, with spores verrucose, 3.4-4/* thick. Similar plants from Hungary also labelled G. lageniformis are in the Herbarium of the Museum of Paris. Another example from Charlottenburg in the same herbarium (P. Sydow, coll., as G. fimbriatus) has spores distinctly verrucose, 3. 7-4.5yit. In American herbaria one often finds under G. lageniformis plants that we are referring to G. saccatus, northern form.

Spore sac subglobose with a more or less obvious apophysis, brown, nearly glabrous and with a short, thick, often flattened stalk; peristome definite, silky, often paler than the sac, broadly conical, the mouth fimbriate. Fleshy layer brown, rather thick, mostly adnate and not cracking. Columella subspherical, about 4—5 mm. thick. Spores (of plant from Wisconsin) spherical, distinctly warted, 3.7-4.8/*, most about 4fi thick. Capillitium threads straight, not branched, concolorous with the spores, up to ly. thick. This plant is evidently nearly related to G. triplex as shown by long-pointed lobes (indicating a pointed button), absence of flocculence on the outer surface, which is clean and glabrous in large part, and in the definite mouth and similar spores. It differs from G. triplex in the splitting away of the outer layer over the central region and the arching up of the middle layer. The stalk is probably no more obvious than it would be in G. triplex if it were to assume such a position. There is much confusion among authors and in herbaria as to the identity of G. limbatus. This is the only American plant labelled G. limbatus in American herbaria which cannot be referred to G. triplex or G, rufescens or G. pectinatus. Most of the collections at the New York Botanical Garden labelled G. limbatus are G. rufescens, e.g., from Alabama, Kentucky, Ohio, Missouri, Indiana, Colorado and Canada. All the material in the Path, and Myc. Herb, at Washington as G. limbatus is G. rufescens, as Ellis, N. Amer. Fungi, No. 1309, and others from Ohio and Colorado. Morgan figures a plant as G. limbatus (N. Amer. Geasters, fig. 6) which is probably G. rufescens, as noted by Lloyd and Hollos. A plant in the Curtis Herbarium from Alabama as G. limbatus (Peters, No. 934) is G. rufescens with a short stalk. We are adopting the name of G. limbatus for the present species as it is so determined by Bresadola, as shown by a European specimen from him in the Lloyd Herbarium. This has exactly the habit of the American plant described above, the outer surface clean and separated from the fibrous layer over the center and proximal part of the rays. Another plant from Bresa- dola so labelled has the outer surface earthy and not separated in part. The mouth is distinct in both. Our plants described above are also the G. limbatus of Lloyd, at least in so far as the American specimens are concerned, as shown by a number of plants in his herbarium. Among Lloyd's illustrations of G. limbatus (The Geastrae, figs. 42^16), figs. 45 and 46 represent the species as we have it. His three other figures are probably not the same. Figure 42 of a plant from Rea (England) and fig. 44 of a plant from Hollos (Hungary) apparently represent the dark species noted below and considered G. limbatus by English authors and by Hollos. It is certain that the G. limbatus of Hollos and of Massee and Berkeley and to all appearances that of Elias Fries* is not our plant, and we have never seen anything like it in this country. It is a large, usually very dark plant (blackish brown; some forms are paler and glaucous) with a short thick stalk, a large, definite, fimbriate mouth of * In the Curtis Herbarium are two plants from E. P. Fries (Upsala) labelled by him G. limbatus, but they are really of pectinatus. Worthington G. Smith gives a figure (Grevillea 2: pi. 17, fig. 2) as G. limbatus which has all the appearance G. G. pectinatus except that grooves are not shown on the peristome. PLATE 64 Geaster limbatus Burlington, Wisconsin [lower right]; Kansas, Xo. 8252 [other three] LVC0PERDAC1 \l 109 more brownish tint and with a universal flocculent covering that holds earth tightly as in G. rufescens. In fact, the appearance is very much that of rufescens except for the black- ish and more glabrous spore sac and more definite mouth. It is beautifully shown in Hussey's Illustrations, pi. 2. Good plants from Hollos in the Farlow Herbarium and from Massee (determined by Berkeley) in the New York Botanical Garden Herbarium are alike. The former has spores which are distinctly warted, 4-5. 2/i thick, and with which those of the latter agree (4.2-5.5^). Another plant from Massee (Chiselhurst) so labelled is the same. Plants from Germany (Berlin; Magnus, coll.) labelled G. rufescens by the collector are also the same: nearly black, mouth distinct. The outer surface of this blackish plant of Northern Europe is quite different from that of our plant, and it does not peel off. Neither Hollos nor any other European author mentions the separation of the outer layer in limbatus. The spores as given by Hollos are 4-5, often 6/i thick, which is too large for our plant. Geaster pseudo-limbatus is represented from Hollos in Lloyd's Herbarium and apparently does not agree with either idea of limbatus discussed above. Illustrations: Fries, Th. C. E.

Spores (of a plant from Ohio; Underwood, coll.) spherical, distinctly warted, 3.4—i.ln thick. Capillitium threads wavy, up to ly. thick. The plant seems common in the middle west, less so elsewhere. We know of no record for the southern states, but there is in the Curtis Herbarium a plant from Ala- bama (Peters, No. 198) as G. saccatus that we believe to be this species. The mouth is very long and narrow and not at all like triplex, but is not crumpled. Lloyd mentions such a mouth as occurring. The nearest relative seems G. triplex, which differs in even 110 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA mouth and smooth outer surface. Lloyd now considers his G. Morganii a synonym of G. Archeri Berk. (Hooker's Fl. Tasm. 2: 264, pi. 183, fig. 9 bis. 1860) but compared with American G. Morganii, the lobes of G. Archeri are more slender and tapering, and the outer surface differs in not being cracked. The fleshy layer looks quite different and has a hard, cartilaginous appearance with few cracks, instead of the softer, more leathery appearance of the rimose fleshy layer in G. Morganii. The spores are the same. The type material of G. Archeri at Kew consists of two separate mounts of one open plant each, both from Tasmania (Archer, coll.). The plants have long, tapering and twisted lobes, rather pliable ; fleshy layer thin, continuous ; outer layer with texture of leather, not cracked in radial lines; spore sac deep brown, glabrous, mouth apparently as in G. Morganii, but somewhat obscured by pressure. Spores (of No. 28) spherical, regularly warted, 3.4-4yu thick (pi. 116, fig. 14). Illustrations: Lloyd. The Geastrae, figs. 31-36. Morgan. North Amer.

Rays about 5-7, upright or revolute, the base strongly saccate. Fleshy layer when fresh pallid, faintly or distinctly pinkish, about 0.8 mm. thick. Spore sac light or dark drab, glabrous, dull; peristome, broadly conical, definite, sur- rounded by a paler depression or much paler all over (at times nearly pure white) ; mycelium attached only as a basal strand, the submerged part of the plant, which is more often all in the button, not binding trash to it, but coming up nearly clean, the mycelium forming a powdery-looking, mouldy layer about 1 cm. from the surface. Spores (of No. 7350) spherical, minutely asperulate, 3. 5-4. 3m- In Chapel Hill we find this only under cedars, but the Florida collection was under oaks, though otherwise exactly like the others, the whiter peristomes being matched in some of our collections. Our plants are very small, only 6-15 mm. wide when open in the dry state, and they look most like G. mirabilis. That is separated by the strictly epigeal and crowded habit, absence of point, strigose surface and entirely different mycelium. The tropical form of saccatus may run much larger than ours, but there are intermediate sizes. What we are calling the northern form of saccatus runs somewhat larger than ours and has much smaller spores. There is still some doubt as to what the true G. saccatus is. As Fries described it, PI.ATK (o -. Geaster mirabilis. No. 7331 [above] Geaster saccatus. No. 73S0 [below] l.WOPERDACEAE 111 it is obviously in the G. triplex rather than in the G. fimbriates series, as indicated by the radicating, basal mycelium and the clean or trashy, adnate, soft, leather colored outer surface, and long, narrow points of the rays. Authors and collectors have refer- red to G. saccatus both G. triplex (including the lageniformis form) and G. jimbriatus, as well as the plant that we are calling G. saccatus. Lloyd confuses the latter two in America and has also referred the lageniformis form of G. triplex to G. saccatus (see plants at the New York Botanical Garden, sample box). Morgan distinguishes them properly by the difference in the mouth, but fails to call attention to the difference in the outer surface which is at least as important. Rick has distributed from Brazil as G. saccatus two quite different plants; one (Fungi Aus.-Amer., No. 330) which looks just like G. fimbriatus, with rlocculent trashy outer surface and indefinite mouth. The spores, however, are distinctly larger than in G. fimbriatus, faintly warted, 3.8-4.6ju thick. Another (Fungi Aus.-Amer., No. 261) is just like our G. triplex, except that the outer surface is cracked in a mottled way rather than in radial lines (spores 3.5-4. \/x). This mottled cracking may also be noted in U. S. American G. triplex (as plant from Love- land, Ohio, noted under that species). Rick's figure of G. saccatus (Broteria 5: pi. 2, figs. 6 and 8) shows a little plant with distinct mouth and clean surface that looks just like the plants we are calling by that name. What Spegazzini distributed from Argen- tina as G. saccatus (Dec. Myc. Arg., No. 44) is a hygroscopic plant with an indefinite mouth and about the size of G. mammosus. It is evidently not the Friesian species. (This is noted also by Lloyd.) 7173. Under cedars, buttons covered up, The Rocks, Sept. 26, 1923. Peristome very pale. Spores 3.2-i.ln. 7441.

Geaster saccatus Fr., Northern Form Plate 115 The following is drawn up entirely from dried plants: Plants saccate, of medium size or rather small, the expanded rays with a spread of 2.5-4 cm. (see note on a larger form below); buttons subglobose with a point up to 4 112 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA mm. long, or rarely with only a rounded umbo. Mycelium strictly basal and radicating by flocculent strands from a central basal point ; outer surface felted or nearly smooth, almost clean or at times with a few bits of rotten wood or leaves, not cracking, with some tendency for outer layer to separate on the rays which are 6-9, pliable, thin, expanded, with the tapering rips revolute; fleshy layer reddish brown, thin, adnate, somewhat cracked. Spore sac 10-13 mm. broad, sessile, surrounded below by the saccate base, smooth, brownish drab to gray-drab; peristome silky, paler or nearly concolorous, distinctly or rather vaguely limited. Columella not obvious. Spores (of plant from Asheville) spherical, dark, minutely but clearly warted, 2.2-3.3/*, distinctly smaller than in the southern form. Capillitium threads about the color of the spores or paler, 5-7.5/* thick. Gregarious on leaves of deciduous trees with a tendency to crowding, which is more or less obvious in most collections. Apparently rare. We have not found it at Chapel Hill. Neither this nor the southern form can be distinguished from G. triplex by the absence of point on the buttons, as there is a point or umbo present both when fresh and dry. Buttons in the same collection may vary from slightly umbonate to pointed like our photograph of the Asheville collection. Hollos, Morgan, Trelease, and Lloyd include our U. S. American plant in G. saccatus. Hollos separates it correctly from G. lageniformis by its soft outer peridium which is usually free from trash. It is further separated from that species which has a firm, hard outer surface by the absence of longitudinal surface cracks that are usually present in the latter, and, in the northern form, by the smaller and less rough spores. Hollos is wrong in considering G. velutinus the same as G. saccatus. The former is very easily distinguished from G. saccatus by its larger size, firmer, harsher, paler, more spongy-looking and more separable surface layer. At the New York Botanical Garden is a collection that we take to be this (Gentry, coll. Two buttons and an open plant; no data). The buttons are larger than in the others, 2.2 cm. thick and up to 2.6 cm. tall including the point, which in one is about 1 cm. long, in the other about 4 mm. Surface layer soft and felted, very clean except on the base, separating in places from the middle layer ; mycelium attached to a basal point. Spore sac sessile, mouth very distinct. Spores spherical, minutely warted, 3-3.6n thick. In the Lloyd Herbarium there are two collections of G. saccatus from Berlin (Magnus, coll.). They are like the American plants, with surface nearly or quite clean, peeling off to some extent from the tips of the rays. Illustrations: Hollos. 1. c, pi. 10, fig. 19. Lloyd.

Walkeri Buttons subspherical with or without B small blunt point, gregarious to subcespi- tose, 1-1.5 cm. thick, epigean and basally attached to an obvious floccose mycelium, surface felt-like, not strigose. very dark brown (verona brown of Ridgway), splitting into 6 or 7 bluntish rays which extend only about one-third to one-half the distance and confine the spore sac to a deep cup, outer layer not at all separable. Fleshy layer when drv varying from dark brown to much paler. Spore sac grayish brown, the mouth without a peristome, fimbriated about as in G.fimbriatus. Spores minute, faintly rough, 2-3. 2/u. The plant differs from G. fimbriaius in entirely different habit (basal attachment of exposed buttons and inseparable spongy surface) and from G. saccatus and its rela- tives in absence of peristome and very dark color. The plants are larger than any species of the saccalus group except saccatus itself. The spores are smaller than in any of the saccatus group except what we have called the small-spored northern form.

Plates 31, 66,67 and 115 Unopened plants seated on the substratum (not embedded in it) and therefore attached to the mycelium only at the base, ovate and bluntly pointed at the top, up to 2.7 cm. broad and' long. Surface dull and finely felted-tomentose, very much like the surface layer of Lycoperdon leprosum. It is flesh color, becoming creamy yellow or buff color on drying. Outer peridium splitting into about 7 reflexed or expanded seg- ments which are a pretty flesh color on the inner (upper) surface when fresh. As these dry they split more or less into two thin, fibrous, persistent layers, a characteristic habit, and usually curl backward under the basal part which remains convex or flat below. Inner peridium smooth, appearing minutely felty under a lens, dark brown or sometimes light gray (when collected perfectly fresh), subglobose, attached by a broad or rather narrow base, almost or quite sessile; mouth small, fibrillose and later lacerated, sur- rounded by a distinct, radially fibrous, broadly conical, silvery gray or light to dark brown area which is about 5 to 8 mm. in diameter. Columella obvious and clavate in the button; slender and more obscure in the mature plant. Spores (of No. 4095) spherical, 2.5-3.3// thick, most about 3yu thick, distinctly as- perulate and with a halo, deep smoky purplish brown. Capillitium threads rather large, up to 11m thick, often branched near the tapering tips. In an unopened button of average size, a microscopic section of the peridia showed the following: outer peridium composed of four distinct regions, (1) a surface layer about 35(MO0m thick in which the threads are large, irregular, entangled and ap- proximately perpendicular to the surface of the plant; (2) a very thin layer 50-65m thick in which the threads are small, regular and extend approximately parallel to the surface of the plant; (3) a slightly thicker layer 130-150p thick in which the threads are small, regular and much entangled; and (4) a very thick (1.5 mm.), fleshy region com- posed of large parenchymatous cells. Inner peridium composed of a single very thin 114 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA layer made up of delicate threads that run approximately parallel to the surface. The threads of the four layers of the outer peridium pass into each other, but at maturity the fleshy layer and the two outer layers (which are an inseparable unit) are easily removed from the third layer. The columella, inner peridium, and all the layers of the outer peridium are continuous with each other at the base. In this species Cunningham finds (1. c.) that the basidia are uninucleate and the plant appears to be haploid throughout its development. The nucleus divides to form nuclei for each spore, usually four. Clamp connections were not found in any part of the plant. All attempts to germinate the spores were unsuccessful. A rather common, large plant that prefers pine woods. It is easily distinguished from its relatives of similar habit by the larger size and minutely felted-tomentose, not hairy, outer peridium which splits into two persistent layers. In many individuals there is plainly to be seen on the under side a circular scar marking the area of attach- ment. From a part of the type collection of G. Readeri from Australia (Grevillea 16: 73. 1888), at the New York Botanical Garden, it is shown that it is the same as G. velutinus, the plants not being distinguishable from the American ones in any way, the surface pale, velutinate, peeling off in part; peristome distinct, size and shape of plant the same; spores spherical, very minutely warted, 2.8-3.3^ thick. There are two other plants mounted in the same herbarium that are also marked "type specimens." These have some sand on the outer surface, but the spores are the same, 3-3.5/j, thick. The plant was first named G. australis by Reader, a name previously used by Berkeley. A plant from New Zealand determined as G. Readeri by Massee (N. Y. Bot. Gard. Herb.) is not the same. It has the surface more strigose-tomentose and not peeling off, and the spores are distinctly different, warted, 3.8-5/*. The plant distributed by Rick in Fungi Austro-Amer., No. 13, as G. triplex is G. velutinus. We have a plant from Brazil (Murrill, coll.) which seems intermediate between velutinus and subiculosus. The silky peristome is very distinct, and the button has almost the same surface as G. velutinus; the mature plant is nearly smooth. The spores are minutely warted, 2.5-3.6/t thick.

Plates 115 and 116 The co-types of G. radicans (Grevillea 2: 49. 1873) in the Curtis Herbarium (as G. Curlisii) show it to be closely related to G. vclulinus. In so far as the appearance goes, it is only a fornicate form of that species, as Lloyd says (Myc. Notes, p. 155; The Geastrae, p. 31). There are two mounted plants with basal cups gone and one perfect plant in a box, all Ravenel, No. 953. Ravenel's ms. notes accompany the last specimen. The velutinate outer surface and the felted spore sac are exactly as in G. vclulinus. A microscopic examination, however, reveals a difference in the spores, which are larger than in G. vclulinus, 3.5-4m thick, and more distinctly rough. We have examined the plants from Florida (Sarasota, on a cedar stump) in Washington, one of which was photographed by Lloyd (The Geastrae, fig. 57), and find them exactly like the types, the spores 3.4-4/* thick. The basal cup is a strong, pliable membrane, free from earth, and in no w^ay like the delicate, submerged cup of G. jornicatus and G. coronaius. We find at the New York Botanical Garden a specimen of this plant from Bermuda, which extends its known range. The spores of this plant are spherical, distinctly warted, 3.8-4.8/u, most about 4.1m thick. The species is reported as new to Europe by G. Lind in "Danish Fungi as Represented in the Herbarium of E. Rostrup," p. 401, 1913 (no description). Rick figures a plant as G. radicans from Brazil (Broteria 5: pi. 5, fig. 9) that is not fornicate and looks exactly like G. triplex with a large collar. He had earlier reported this as G. triplex, and says that Bresadola referred his plant to G. radicans. It may be G. vclulinus, but cannot be accepted as G. radicans. Lloyd thinks that G. Wdvntsckii (from Spain) is the same as the American plant (Myc. Notes, p. 315, pi. 101, fig. 3). The Cuban plants reported in the original description as G. radicans are represented in the Curtis Herbarium as Wright, No. 873. These three plants are all buttons and are not G. radicans. They were entirely submerged and are covered with humus held on by a flocculence as in G. rnjescens; a single stout basal strand is attached to buttons in two cases; not pointed. The types were sent to Berkeley by Curtis, who received them from Ravenel, who also sent notes and added that if a new species then "it is G. Curlisii" wishing to honor Curtis. Berkeley, however, ignored this wish of Ravenel's and named it G. radicans B. & C. (See Lloyd, Myc. Notes, p. 171.) Ravenel in his notes says "with a sulcate- plicate mouth," but the mouth is not truly so as we are defining that character. The best specimen has the mouth pinched into a few crumples, but the others do not show this. As the usual form and spores distinguish G. radicans from G. vehttini(s, we think it well to retain the name, though it would be better to reduce it to a variety. 116 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Illustration: Lloyd.

Plates 65, 67, 68, 115 and 116 Densely cespitose to single in considerable numbers, and arising from an obvious white mycelium which binds together the leaves and twigs. Buttons spherical, not pointed, but a few with a small umbo when dry, 0.8-1.2 cm. thick, strigose-tomentose, reddish brown to ochraceous buff, a few blackish; mycelium basal, the buttons quite exposed or partly covered with loose trash (completely covered in No. 7173). Ex- panded plants 1.4-2.2 cm. wide; lobes usually 6 or 7, expanded (tending to become elevated when dry), the basal half bowl-shaped and holding the completely sessile inner peridium which is 6-9 mm. thick, subspherical, gray, with a delicately felted surface; peristome distinct, silky, more or less elevated, conical, immediately after exposure pale from a granular-looking, minute pubescence, with a darker line around the base, soon darker than the peridium; mouth fimbriated, not sulcate. Fleshy layer when first exposed about 0.5 mm. thick, smooth, light flesh color, soon darker and drying to a thin, adnate, continuous, gray-brown membrane. Spores (of No. 7077) very dark, minutely warted, 3.2-3.8/*, most about 3.6/u. Capillitium threads sinuous, thick- walled (practically no lumen), much paler than the spores, about 3.4/* thick, the tapering ends smaller. From G. saccatus the present species is distinguished by cespitose habit, much smaller size, hairy surface, less pointed buttons when dry and larger spores. Both have the habit of growing exposed (epigeal). The species was originally described from French Guiana and is known also from Brazil, Africa, and the Orient. Our plants are the same as plants received through the kindness of M. Patouillard and collected in Brazil by Rick. The young buttons have the same strigose-tomentose surface ; the older ones more felted-tomentose ; spores exactly as in our plants, faintly warted, 3.4-4/i thick, not like the smooth and smaller spores of what we are calling G. subiculosus. Rick considers G. trichifer the same (see Myc. Notes, p. 804), but Lloyd thinks it different (see that species). In our No. 7077, some of the plants are apparently as strigose as G. trichifer (which see), while others show only a matted tomen- tum, exposure to weather having a considerable effect. The species is represented in the Kew Herbarium by five cards of material: three from Cuba (Wright), two from Ceylon (G. H. K. T.), and one from Uganda, Africa, (Diimmer, No. 1462). All these have the spores of G. mirabilis, and in appearance are the same as the Chapel Hill and Brazilian specimens except that none shows quite so strigose a surface. The spores of the plant from Ceylon, No. 184, are 3.2-3.8/* thick, minutely rough. The African plants connect up directly with G. papyraceus, with outer peridium more papery-looking than in the others. The spores of this collection are 3.5-4.2/* thick, with surface as in the others. ri.\i i 68 [Top row] GEASTER Harioiii.

The Japanese plants are all open ; peridium extremely thin and paperv, pliable, pale creamy straw color, outer surface with a concolorous coat of very thin soft weft in places. Mycelium membranous; fleshy layer almost all gone; inner peridium broken or worm eaten, peristome not shown. The Bonin Island plants are strigose-hairy outside; two cespitose buttons, one grown button apparently torn open at the top, and one open plant; even the last is strigose. These look like G. mirabilis. Fleshy layer intact and rays much stiffer than in the Japanese plants. Peristome distinctly silky. A microscopic examination, however, shows the spores to be identical in the two collections. In the Japanese plants they are spherical, finely but distinctly warted, 3.5-3.8/i thick, with a very distinct and shiny oil drop. In the Bonin Island plants they are 3.6-4^ thick, surface and oil drop as in the others. We can confirm Lloyd's opinion (Myc. Notes, p. 181) that Coilomyces Schweinitzii B. & C. is an un- opened Geaster related to, if not the same as, G. mirabilis. The plants in the Curtis Herbarium have spores exactly like our Chapel Hill G. mirabilis, spherical, minutely warted, 3-An thick (pi. 116, fig. 15). Geaster caespitosus is apparently the same, with the usual slight variations which are to be expected. The ample type collection in the Lloyd Herbarium has the exact appearance of our plants except that the strigose character is not so obvious. The surface is softly felted, becoming smoother; peristome silky, sharply defined by a ridge; the plants attached by a pointed base to the abundant mycelium. Spores slightly smaller than in our collections, very minutely warted, 2.3-3.4^. We find at the New York Botanical Garden a box of miscellaneous material without names but labelled Ohio, Lloyd, No. 255, in which, mixed with three other species, is a dense clump of small plants that are G. caespitosus and just like the types. The type of G. lignicola Berk. (Journ. Linn. Soc. Bot. 18: 386. 1881) at Kew from Rockingham, Australia (Thozet, No. 908), is apparently not different from G. mirabilis. There are two crushed buttons and one open plant on fragments of plant material. Mycelium not very obvious; surface of both buttons and mature plants nearly smooth. Spore sac dark brown with fimbriate mouth. Peristome characters not obvious on account of the way the plant is pressed and glued down. Spores spherical, minutely warted, 3.2-4m thick.

Spore sac subglobose, sessile in the cup-shaped base, grayish brown, glabrous; peristome very distinct, flat with elevated center, mouth becoming fimbriate. Spores very minutely rough, 3-3.6/j. thick. Murrill's notes on the fresh condition say, "Outside with long, stiff hairs, ferruginous- fulvous, shaggy-setose . . . fleshy layer dirty white; spore sac flattish acorn- shaped, avellaneous. . . . Spread 5 cm., center 2 cm." One of the largest plants is now broadly spread and reaches 4 cm., the smaller ones if spread would be about 3 cm. The plants are growing on leaves and twigs and have the habit and shape of G. mirabilis, which differs from the Jamaica collection in being much smaller, less strigose, with outer layer not peeling, and in the smaller spores. The original plants were collected by Rick in Brazil. He now considers it a form of G. mirabilis, while Lloyd thinks it different. The plants shown in Lloyd's photo- graphs are not larger than G. mirabilis, and in fig. 1251 the surface does not appear more shaggy than in G. mirabilis. Illustrations: Lloyd. Myc.

Buttons 9-11 mm. broad, completely exposed, obovoid, pinched below to a point connecting with the mycelium; apex concave by collapse (when dry), not pointed. Surface pale buff, wrinkled, glabrous, but with the soft appearance of leather; tardily opening by 6 or 7 rays, the sinuses extending into about a third of the peridium, leaving the basal part unchanged as a deep cup enclosing the sessile spore sac. Fleshy layer drab brown, thin, adherent, not cracked except across the bottom of the rays. Spore sac 1 cm. broad, subspherical, glabrous, brown. Peristome not distinctly outlined or distinctly silky, fading into the sac surface about as in G. fimbriatus, sometimes sunken and then more distinctly outlined; mouth scarcely elevated, the opening fimbriate. Spores (of Jamaica plant) spherical, smooth, 2-3// thick. This is clearly distinguished from G. mirabilis Mont, by larger size, absence of tomentum, obscure peristome, and smooth and much smaller spores. Even very young buttons are practically glabrous and nearly white. The plant described above is certainly the same as that illustrated by Lloyd in Lycoperd. Australia, etc., fig. 19, and Myc. Works, pi. 100, figs. 4 and 5. He refers to it as G. subiculosus, which he considers a form of G. mirabilis. From the description of G. subiculosus (Grevillea 16: 97. 1887) one would hardly refer the present plant there, as it is described as furfuraceous and LYCOPERDACEAE 119 wood colored on the outside, with spores 4;u thick, but the types at Kew from Trinity Bay, Australia, are essentially like our plants from Jamaica. There are two open plants and several more or less crushed buttons. The best specimen shows a spore sac about 7 mm. thick, dark brown; peristome not outlined by a groove or ridge but paler and fibrous. Surface of buttons minutely spongy, of older plants nearly glabrous. Largest button 1.1 cm. thick. Subiculum white, membranous. Spores spherical, practically smooth, some finely dotted, 3-3. S/u. Lycopcrdon f-usio B. & C. is apparently a Geastcr. The co-types in the Curtis Herbarium, No. 253 (Cuba), are all buttons, but they look just like another collection so labelled, also from Cuba (Wright) , in which the plants are open. These last are small Geasters looking very much like G. subhiilosiis, with pale, smooth surface, and con- spicuous mycelium. The spores, however, are not those of any member of this group, but are 3.8-4.Sm thick, with distinct, blunt warts. Illustrations: Lloyd. As cited above. Jamaica. Hope. Earle, coll. (N. Y. Eot. Gard.

Mycelium basal; outer scurf wearing off gradually and exposing the glabrous shining copper brown or darker, fibrous layer of the rays, which are about 8-12 in number, of unequal width and strongly hy- groscopic; fleshy layer thick, adnate, smooth, at first gray-brown then darker brown to blackish. Inner peridium 5-15 mm. thick, subglobose to compressed, very finely puberulent, sessile, grayish to brown then darker; peristome distinctly outlined by a depressed border, plane, silky-strigose, the mouth elevated and papillose-fimbriated. Expanded plants up to 5.5 cm. broad. Spores (of a Canada plant) spherical, minutely warted, 3-3.7 n- Easily denned in the hygroscopic section by the clearly outlined silky-fibrous, plane and non-sulcate peristome. The above description was mostly drawn from a fine collection from Canada, containing one button and plants of various ages and sizes (N. Y. Bot. Gard. Herb., no data except Canada). Plants in the Lloyd Herbarium from Paris (L. Rolland) are like American speci- mens, with a spongy, yellow, nearly clean superficial layer peeling off in flakes; the mouth distinct. Plants in the same herbarium from Tucuman, Argentina (Leon Castillon, coll.), are like the United States and European plants except that the outer layer when present is covered with sandy earth. Geaster argentens Cooke (Grevillea 17: 75. 1889) is represented at Kew by three sets on the same sheet, all from Fort Carlton, Saskatchewan (one lot not named). The plants of the upper lot with pasted label giving fullest data, we take as the types. The plants have the appearance of G. mammosus w-ith outer superficial layer weathered off, 120 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA showing the whitish, fibrous layer and blackish fleshy layer; spore sac sessile and largely enclosed by the strongly hygroscopic lobes. The mouth area is obvious as a silky zone, the center more or less elevated and lacerate. The spores, which are spherical, distinctly warted, 3.7-4.5/* (pi. 116, fig. 13) are distinctly those of mammosus and not of floriformis, which are larger (5-7/z). Hollos considers G. argenteus the same as G. floriformis, but he apparently had not seen authentic specimens. Geaster argentatus Cooke and Massee from Brisbane, Australia, is closely related. A part of the type collection is at the New York Botanical Garden. It has a definite silky peristome; spread of rays 3 cm., the outer surface scurfy and ochraceous at first, then smooth and gray to buffy gray; fleshy layer reddish brown; spore sac 12 mm. thick, finely furfuraceous to sub-granular, gray-brown to reddish brown, sessile. Spores dark, mostly spherical but some irregular, 4.5-6^ (pi. 116, fig. 17). Other plants from Kew Herbarium labelled G. argentatus Cooke from Victoria, Australia (not types), now pasted on the same sheet with G. argenteus, are quite different from the types, and we take them to be G. Drummondii, which they resemble in all important respects: mouth sulcate, spore sac granular to subasperate. Illustrations: Destree. 1. c, pi. 9, fig. B.

Mycelial layer closely adnate with adhering sand. Fleshy layer closely adnate, light color, not rimose. Inner peridium subglobose, with a very short but distinct pedicel in some specimens, in others appearing sessile. Mouth even, conical, acute, definite and usually darker colored than the remainder of inner peridium. Columella indistinct. Spores globose, rough, 3-4yu." PLATE 69 Geaster rufescens. Xo. 985 LYCOPERDAC] \r 121 The abundant type collection from Jupiter, Fla. (Culbcrtson, coll.), shows this to be a remarkable plant intermediate between G. coronatus and G. Jloriformis. In some the rays are distinctly revolute with the center elevated, in others the rays are closed in over or entirely under the sac. Though some of the rays are pliable they are dis- tinctly hygroscopic, expanding quickly in water. Spore sac very faintly felted to glabrous, not at all granular-dotted as in G. coronatus, about 1 cm. thick, practically sessile; peristome varying from sharply outlined by a groove (about as in G. coronatus) to a less emphasized boundary as in G. mammosus; mouth apparently brown in the fresh condition, washing out pale and becoming lacerate. The outer layer of sand is thin and the flocculence holding it is very delicate and obscure. Spores minutely and ir- regularly warted, 3.2-3.8/z thick. Mixed with the types is a good specimen of G. coronatus, and this is almost certainly the plant referred to by Lloyd in his footnote as being an exception. From the appearance of the rays of G. arenarius, which are acute, but not acumi- nate, the button is probably little if at all pointed. At the New York Botanical Garden there are two plants from Florida labelled G. fimbriatus (Underwood, coll., No. 1801a) that are almost certainly this species, though the mouth is only vaguely if at all deter- minate. The plants are small, hygroscopic, covered with sand on the outside ; peristome vague, spore sac nearly glabrous; spores minutely warted, 3.7-4.5yu thick, just like those of Lloyd's plant and smaller than in G. ftoriformis. The species is very near G. floriformis (see Lloyd, Myc. Notes, p. 143) and this approach is further emphasized by the vague peristome of the Underwood plants, which have the same spores as Lloyd's plants. The rays of G. arenarius are distinctly less rigid than in G. Jloriformis, but the smaller spores of the former are now the principal character separating the two species. The extreme variation of Geasters is well shown by what appears to be a giant form of G. arenarius that is represented in the New York Botanical Garden by two very large plants from Greencastle, Indiana (as G. rufescens). They are 3.5-4 cm. thick with the rays closed over the spore sac. The peristome is vague, but the spores are like those of G. arenarius, minutely warted, 3.5-4^ thick, much smaller than in any other related species. Another interesting case is that of plants from Lake Titicaca, noted under G. jloriformis. Illustrations: Cunningham. Proc. Linn. Soc. N. S. W. 51: pi. 5, figs. 24, 25.

Plates 69 and 115 Plants large, the button subspherical, not pointed, entirely buried until dehiscence, when open 5 to 8 cm. wide; the thin outer mycelial membrane covered with earth or 122 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA trash and tending to split away in patches from the fibrous layer which is flesh colored when fresh; rays splitting about half way to the base into about 7-9 lobes, or only shallowly into many more, the lobes when fresh are expanded or recurved, when dry recurved or the tips incurved, the unsplit basal portion convex above (vaulted beneath) as in the fornicate group. Fleshy layer of outer peridium very thick when fresh, up to 5 mm.; when dry forming a thinner crust with a felted-looking, brown surface on the face of the fibrous layer. Spore sac up to 4 cm. thick, depressed-globose, the base usually constricted into a short thick stalk, not rarely with a low apophysis around the lower side of the spore sac some distance from the stem; color when fresh varying from pale flesh color to grayish flesh or deep brownish gray, when dry brown to gray brown, the surface not glabrous but covered with very minute, inherent scurfy dots (granular- velvety). Mouth slightly elevated, fibrous and becoming fimbriated, without a definite peristome (indeterminate). Columella large and subglobose, up to 1.5 cm. thick, the basal part with a peripheral extension as far as the apophysis. Spores (of No. 985) globose, deep brown when mature, 3^1.4yu thick, minutely warted or asperulate, with a halo. Capillitium of simple threads which are about 3.5-4.8n thick. This fine species, which is not at all rare in America, grows usually around the bases of oak stumps and occurs in groups. One of the most remarkable characters is the very pleasant and decided fruity fragrance of the unopened and just opened plants. There has been considerable confusion regarding this plant and G. limbatus. As understood in Northern Europe (Fries, Berkeley, Massee), the latter differs in the expanded, not reversed rays, the darker and smoother inner peridium, the thinner and less spongy fleshy layer, and the more obvious peristome. For G. limbatus in the sense of Bresadola, in which sense we are using the name, see under that species. European specimens of G. rufescens are rare in American herbaria. One from Bresadola in the Lloyd Her- barium is like our plants, with spores 3.6^1.2/* thick, minutely warted. For comparison with G. triplex see that species. Illustrations: Bulliard. Herb.

Rays expanded or the tips incurved, pliable, about 5-8 in number, center concave below; fleshy layer adnate, thin and brown. Spore sac 1.5-2 cm. broad, subsessile or with a short stalk, dark brown, harshly asperate with short, setose hairs. Peristome rather indefinite (not sulcate), silky, mouth fimbriate. Spores (of plant from Jalapa, Mexico), small and minutely warted, 2.6-3.6^ thick, often seeming slightly angular. Except for the asperate spore sac the plant is very like G. rufescens or G. fimbriates and seems certainly to belong to their group. \Ye have seen the type collection of G. Hieronymi in the Lloyd Herbarium, and find that it agrees closely with the Mexican plants. There are also two other lots in the Lloyd Herbarium labelled G. Hieronymi from Brazil (Rick, coll.). One of these is as described above and like the type ; the other is something different, with a sulcate mouth. Illustration: Lloyd. Myc. Works, pi. 229, fig. 2347. Mexico. Jalapa.

Geaster Lloydii Bresadola Plate 117 Buttons evidently subterranean or nearly so (submerged in humus), about 1.5 cm. thick when dry, spherical, not pointed, woolly felted all over or with spots where the softer wool has collapsed between the stiff er groups of hairs ; largely covered with bits of leaves and trash, in some places nearly clean; the central point below attached to obvious mycelial strands. Rays six or more, thin but rather rigid ; center concave below usually; the thin tomentose outer layer with a strong tendency to peel off except at tips, as in G. limbatus (sense of Bresadola) ; fleshy layer deep reddish brown to nearly black, rimose, adherent. Spore sac sessile, thin, collapsing, dark brown with paler areas at times or rarely pale all over, surface dull, minutely granular velvety, almost exactly the color and surface of our G.fornicatas; mouth large, fimbriate; peristome not defined, concolorous. The peeled off outer layer is delicate and pliable, and is usually torn into strips. As it pulls away from the fibrous layer it leaves a narrow, root-like 124 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA core projecting downward from the central point where the mycelium was attached. (This core is lacking in No. 8702 from Porto Rico.) Spores (of No. 7436) sometimes faintly angular as well as minutely warted, 3.5-4.2^ thick. Capillitium threads up to 7.4ju thick, strongly encrusted. We have not seen the types, but as our plants agree almost perfectly with the description of G. Lloydii, we refer them to it with confidence (see Myc. Notes, p. 50. 1901). Lloyd, who collected the types in Samoa, later merged the species with velutinus (Geastrae, p. 35). If our determination is correct, we think this a good species. The species is in the rufescens-fornicatus group and almost exactly intermediate between them in habit. The outer layer separates, not as in velutinus, beginning at the tips, but as in fornicatus, radicans, and limbatus, beginning at the center. It is dis- tinguished from fornicatus by the imperfectly fornicate habit and by the strigose and much less trashy surface. The spores are larger than in G. Hieronymi and the spore sac is not asperate; G. fimbriatus differs in more saccate base, smaller spores, entire absence of hispid hairs, and in usually lighter color. In an ample collection from Florida, consisting of 8 buttons and 12 open plants, all but one open plant were very dark; another collection of a single plant from the same section was pale brown. This species, as well as G. fimbriatus and Astraeus hygrometricus, shows that in some, if not all, Geasters with so-called universal mycelium, the true mycelium is really only basal and the felted "mycelial layer" only an outgrowth from the button. Ex- panded plants of G. fornicatus often show a hole in the bottom of the sac-like base as if it had been pulled away from a firmer basal attachment. Florida. Gainesville. On an old stump.

This cup is always completely covered with adhering trash and earth due to the flocculent mycelium weft- ing it. Rays firm, the fleshy layer dark brown and adherent or partly peeled off, in old plants worn away; the exposed fibrous layer whitish tan. Inner peridium seated on a distinct, whitish, short stalk about 2-3 mm. long (in our plants), subglobose or urn- shaped to depressed, constricted near the base so as to form a ring; surface dark brown, finely velvety; mouth large, slightly elevated, fibrous lacerated, wrinkled, without a distinct peristome, but the paler brown fibers in older plants have a distinct limit exactly as in G. limbatus (sense of Hollos), which is very near. Columella not large, about 3 or 4 mm. high and 2.5 mm. broad (in the Smith's Island plant).

Xo. 7093 [middle four dry plants]; No. 7097 [lower three fresh plants] LYCOPERDAI EAE 125 This is a rare plant in the United States and is reported by Lloyd only from Texas and Catalina Island. In the rest of the world it is supposed to be of wide but erratic distribution (Lloyd, Lycoperdaceae of Australia, etc., p. 21). The report by Curtis that it is common in this state (Catl. Plants of North Carolina, p. 110) almost certainly refers' to what we now call G. coronatus, as all the plants in his herbarium under G. fornicatus are the latter species. Our single collection from this state consists of three plants in fine condition that grew under cedar, but the species is reported as growing under both conifers and frondose plants. It is easily distinguished from G. coronatus by the absence of an outlined peristome and the entirely different surface of the inner peridium . The species is really most nearly related to G. rufescens which is very similar in fundamental characters, as mouth, surface of inner peridium, separating layers of the outer peridium, and concave base when expanded. The spores, too, are very similar. The two species, however, are not forms of the same thing, but are easily distinguished by the fornicate habit, fewer and more rigid lobes, and darker and more densely velvety inner peridium of G.fornicatus. Geaster marchicus is usually considered a synonym of G.fornicatus, and plants so determined by Hollos in the U. S. National Herbarium are certainly this species, as are also those determined by him and repre- sented by No. 950 of J. Wagner's Kryptogamae exsiccatae. Spores of the latter are dark, minutely warted, 3.6-4^. For other supposed synonyms, see Hollos, p. 154. Illustrations: Batsch. Elench. Fung., pi. 29, fig. 168. Corda. Icon. Fung. 5: pi. 4, fig. 43.

Plates 70 and 115 Plants small, in our collections up to 3 cm. wide when freshly expanded; inner peridium about 9-14 mm. thick when fresh, subglabrous to minutely dotted, pale or dark brown, sessile in and surrounded by the concave lower half of the outer peridium; mouth on a more or less elevated, concolorous or paler cone, but without a definitely outlined area around it, the margin fibrous-flocculent and at times lacerate, not sulcate. Outer peridium splitting about half way down into 5-8 lobes which when freshly ex- panded are strongly recurved around the margin of the bowl-shaped base, usually remaining recurved in the dry state, not hygroscopic. Mycelial layer very thin with wefted surface, pale tan or buff to soaked ochraceous when fresh, tending to peel away in part from the rays but as a rule not nearly so much so as in G. velulinus.^ Fleshy layer pallid (nearly white to pale smoky tan; not pinkish) and about 2 mm. thick when fresh, drying down to an extremely thin, smooth or finely cracked up, brown or ochra- 126 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA ceous membrane or scurf which disappears only after much exposure. Buttons quite spherical, not pointed, completely covered by humus and trash and retaining trash over the whole or most of the surface after opening. Columella in the mature plant represented by a small, subspherical, pale core some distance from the base. Spores (of No. 7093) dark smoky brown, spherical, very minutely asperulate, many appearing smooth except under high power, 2.2-3.4//, most about 3/i. Capillitium threads unbranched, about 5m thick, sometimes up to In, usually lighter than the spores, but varying in color in plants of the same colony. This small Geaster grows usually in groups of several, not truly cespitose (rarely crowded in twos or threes), in partly rotten leaves and trash under cedars or in mixed woods. As is to be expected, specimens are found (rarely) that are not saccate but have the outer peridium concave below. It also happens occasionally that the outer layer may peel off completely. For both of these variations see plants from Lynn, England (Plowright, coll.), at the New York Botanical Garden. In American herbaria this is often referred to G. saccatus. Lloyd thinks that G. fimbriatus does not occur in America (The Geastrae, p. 37), though reported by Morgan and others. However, as our plants agree clearly with this species in all important points (indeterminate mouth, splitting of the outer peridium into two layers in part, etc.) , we see no reason not to refer them to it. In cases where the paleness of the mouth area is most pronounced as in plants from Buck Hill Falls, Pa. (see below) , some authors might be inclined to call it definite, but there is no structural boundary and except for color the mouth is exactly as in other forms. The European plant also has a tendency to a paler mouth area. As Lloyd says, the mouth is no more fimbriate than in some other species. The true European G. fimbriatus is represented by plants in Washington (Path, and Myc. Herb.) from lower Austria collected by Zahlbruckner and determined by Keissler. They are just like our plants. We have received from Patouillard another typical European specimen (Jura) with spores minutely warted, 2.5-3.5/i thick. Still a third (N. Y. Bot. Gard. Herb, from Herb, of Thiimen) has spores a trifle larger (3.4-4/u) but is otherwise identical. It grew in coniferous woods and still shows fir leaves attached. A European collection from Sydow (Flora Marchica, Charlottenburger Schloss- garten, P. Sydow, coll.) labelled G. fimbriatus and now at the New York Botanical Garden is not the plant we here describe, but G. lageniformis with much rougher spores and determinate mouth. Our plants agree with Rea's description of G. fimbriatus except in size of spores which he gives as 4-5/j. It is very likely that G. triplex (with G. lageniformis) and G. fimbriatus have been often confused. Geaster rufescens is the nearest relative of G. fimbriatus, and large plants of the latter might easily be referred to it. The thinner fleshy layer, more saccate form, and smaller average size distinguish G. fimbriatus, but there may be connecting forms. Geaster tunicatus as represented in Saccardo, Mycotheca italica, No. 1625 (Mendola; Bresadola, coll.), is G. fimbriatus. The mouth is indefinite, the base saccate. The two species are also treated as synonyms by Hollos. Illustrations: Berkeley. Outlines Brit. Fung., pi. 20, fig. 4. Cunningham. Proc. Linn. Soc. N. S. W. 51: pi. 6, fig. 36.

Spores (of Clements, No. 613) distinctly warted, spherical, 5-7^ thick, or slightly elongated and about 6.5 x 7 An. Capillitium threads straight, thick-walled, up to 7^ thick. The American plants are like those of a good collection from Hollos (Hungary) sent us through the kindness of Patouillard. In these plants the peristome is indefinite, rays strongly hygroscopic, spores spherical or somewhat irregular, distinctly warted, 5-7 x 6-8/i. Similar plants from Hollos have been seen by us in the Lloyd Herbarium. 128 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Good collections of this species from San Diego, California, in Washington and New York show an interesting variation in the mouth. In the plants at the New York Botanical Garden the two plants with mouths visible show a depressed zone around the mouth but the surface of the zone is not silky as in most Geasters, but of the same texture as the remainder of the surface. In one of the plants the mouth was an elevated Dapilla in the center of this zone; in the other it was a plane opening. For a similar variation see plants from Florida and North Dakota entered below. The plants in Washington show a plane opening without a depressed zone. In most herbarium material the spore sac is nearly smooth or faintly powdery. The granules when present are not so large as in G. asper. The rays when dry are either folded over the top of the inner peridium or are curved in more abruptly with their tips under it, or they may take any intermediate position. The species grows in sandy soil and in this country is apparently confined to the western states, occurring also in Europe and Africa. A large form of this with the spore sac 2 cm. thick (in the pressed condition) is represented in the Herbaiium of the Museum of Paris from western Africa. Except in size they do not differ apparently from the American plants. The spores are distinctly warted, 5-6.5 x 6-7(x. An interesting plant that seems referable to this as a variant is repre- sented in the Far low Herbarium from Lake Titicaca, Bolivia (Mrs. Shepard, coll.). The rays are thick, strongly hygroscopic, covered with sand; spore sac densely furfura- ceous, nearly white, peristome vaguely defined by a low ridge, fimbriate; spores spherical to irregular, distinctly warted, 4-5/u thick or up to 6// long. In his treatment of G. delicatus (The Geastrae, p. 11), Lloyd makes the mistake of referring to G. lageniformis when he should have said G. florijormis (see Hollos, p. 67). Illustrations: Cunningham.

Cesalii Rabenhorst Plates 71, 72, 115 and 116 Tlants when expanded 1.5-3.5 cm. broad and up to 3.3 cm. tall excluding the basal cup when present; outer peridium splitting into 4-8 strongly recurved or rarely hori- zontal lobes, the mycelial layer often being stripped off and remaining as an obscure weft which holds together a hollow mass of earth or trash out of which the plant was lifted, the tips of the rays attached to its margin (typical or fornicate form); in other cases the mycelial layer with the adhering trash is lifted with the plant and forms a more or less' persistent coat on the outer surface (form minimus) ; fleshy layer brown, cracking and often seceding in large part from the rays, the central part most persistent and at times forming a low collar around the base of the stalk. Inner peridium ovoid to oblong, 4-14/j thick, brown to umber or slate color, the surface, except when weather- worn, powdered with minute glistening particles; stalk distinct, about 1.5-2.5 mm. long and expanding above into a ridge which in some specimens may have an acute rim like a little collar. Mouth delicately fimbriated, not sulcate, low, abruptly or gradu- ally elevated from a nearly flat, sharply defined silky area which is outlined by a groove. Columella in mature plant not obvious. Spores (of No. 3881) dark smoky purplish, distinctly rough, 4-5. 1/x thick, most about 4.5/1. Capillitium threads up to 6m thick, not sinuous and branching rarely if at all. This species has been confused with G. fornicatus both in Europe and America and it is treated under the latter name by Morgan. We are following Lloyd and Hollos in using the name G. coronatus for the present species. The true G. fornicatus, as now understood, is usually larger and is easily distinguished by the absence of a well defined mouth area, the different surface of the spore sac, and by the smaller and less strongly warted spores. The type of G. minimus in the Schweinitz Herbarium is just like the usual G. minimus of herbaria; the spores distinctly warted, 3.7-4.4ju thick. Another authentic specimen of G. minimus from Schweinitz, now in the Michener Herbarium in Washing- ton, is just like the form that we are calling G. minimus. Lloyd has seen the plant in the Schweinitz Herbarium and says that it is the same as the minimus form. We find it impossible to distinguish between G. coronatus and G. minimus. If the mycelial layer with its trash remains attached and is lifted when the rays bend back we have the minimus form, if not it is the coronatus form, and both forms with intermediates may occur in the same colony. Smaller size does not distinguish minimus, as we have seen the fornicate form with the inner peridium less than 5 mm. thick. In several plants in our collections the ridge around the expanded top of the stem, which is often obvious in stalked species, is terminated by a distinct, fimbriated frill, recalling the broader frill of G. Bryantii. The last mentioned is distinguished by its sulcate and more narrow and elevated mouth, by the distinct columella and by the 130 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA broader frill. Both forms of G. coronatus are widely distributed in the United States and are not uncommon. In Europe the minimus form seems much rarer. The European plant is represented in Torrend's Mycotheca Lusitanica No. 79 (in pinetis), also in Cesati's Herbarium Mycol., No. 1634 (as G. Cesatii. Both in Path, and Myc. Herb., Washington). In G. Cesatii the spores are distinctly warted, 3.8-4.5^ thick. Geaster granulosus is an extreme form or variety of G. minimus with distinctly larger granules on the spore sac and in some cases covering it almost solidly with a white crust, at least as much so as in G. calceus as shown by Lloyd's fig. 9, pi. 95. We have studied authentic specimens of G. granulosus from Austria (Fuckel, coll.) and find the spores to be larger and rougher than in G. minimus, 4.2-5. 6yu thick, often with an angular appearance from the irregular warts (pi. 116, fig. 12). A plant from Ymala, Mexico, has the exact superficial appearance of G. granulosus and the spores approach those of that species, with the same irregularity, but are somewhat smaller, 3.8-5/u. They have the form of spores of G. minimus shown on pi. 1 15, fig. 24, and are only slightly larger. Geaster calceus Lloyd (Myc. Notes, p. 311) from South Africa is very near the last, but with smaller spores (3.5-4.2p), of regular, spherical shape and with equal warts (pi. 116, fig. 11). A peculiar plant is represented in the Path, and Myc. Herbarium by three speci- mens from Waste Land, South Dakota (Wilcox, coll.). It looks like a small, nearly sessile specimen of G. minimus but the spores are distinctly larger and irregular (4.8-5.5 x 6.4-7.5^), with large, unequal warts (pi. 116, fig. 16). The plant bears the ms. name of G. lerreus Ellis, n. sp., with description in ms. attached. It may be a new species, but is more probably an extreme variant of the minimus type. Macbride describes as a new species, G. juniper inus, a plant from Iowa, very close to G. coronatus. It seems scarcely more than a form (Mycologia 4 : 84. 1912). Noack (cited below) reports this fungus, which he calls G. fornicatus, as forming mycorrhizas on the roots of conifers. Illustrations: De Toni. 1. c, pi. 63, fig. H and fig. I (as G. marginatus).

Fibrous layer of the outer peridium splitting into 3-6 rays about half way down or more, the rays recurving and the base becoming arched up (vaulted beneath), leaving the delicate, fibrous, mycelial layer as a distinct, membranous, white cup beneath, with its margin also rayed by slits, the rays attached to the rays of the plant above (typically fornicate).

Capillitium threads unbranched, about 3m thick. Both spores and capillitium very pale yellow-brown (whitish). This is a very distinct and well marked little species and is the smallest known Geaster, the inner peridium of a full-grown plant seldom reaching over 5 mm. in di- ameter. They have the unique habit of growing in moss on tree trunks, as cedar, hickory, elm, etc., and usually from about four feet from the ground up, most of our collection coming from a height of ten to twenty feet. It is not at all uncommon in Chapel Hill, which is the only known station, and is distinctly a cold weather species, appearing in mild wet spells in winter and early spring and often associated with Lyco- perdon acuminatum. The flocculent white mycelium penetrates the old bark and ex- tends itself abundantly between the planes of cleavage. The species is distinguished from G. coronatus, which is nearest, by the much smaller average size, smaller and nearly white spores, and capillitium, and peculiar habitat. For the original descrip- tion, see Bot. Gaz. 36: 306. 1903. 681, 1085, 1479, 1537, 2028, 2029, 2466, 3222, 3231, 6052, 7586.

Plates 74, 75 and 115 Mycelium universal and forming a soft, flocculent coat that holds trash to the entire outer surface of the plant as in G. rufescens; rays few to numerous, typically reflexed but the tips often incurved, central region concave below and elevating the spore sac; mycelial layer with attached earth tending to peel off after expansion as is also the brown fleshy layer, so that the thin, pale fibrous layer may be left almost naked in old specimens; spore sac subglobose to urn-shaped, with or without an apophy- sis, the lower part with radial lines or ridges that in some cases may be quite faint; stalk slender, typically rather long, up to 5 or 6 mm., often with a collar or ring near center or base; surface when fresh covered with a fine powder which is whitish against the spore sac and brown without so as to give the spore sac a whitish bloom where it is thin and a brown-drab color where it is thicker. Mouth long, narrowly conical, prettily sulcate-striate, brown. Spores (of plant from Jamesville, N. Y.) very dark, with large blunt warts, 4.2-5.5/x thick. Capillitium threads up to 7ju thick. A rare plant apparently, and Schweinitz's record is so far the only one from North Carolina. The length of stalk is very variable, e.g., in one good lot from Surrey, England, at the New York Botanical Garden Herbarium (as G. limbatus), the stalk is only 2 mm. long. The species runs into two extremes that are most conveniently treated as species, though intermediates occur. The smallest of these is G. Schmidelii, which also approaches G. Smithii (G. ambiguus, sense of Hollos). The other is G. Bryantii which is distinguished by a deflexed collar around the base of the spore sac. Specimens of G. pectinatus (Upsala) in the Curtis Herbarium are labelled G. limbatus by E. P. Fries. A part of the type collection of G. biplicatus (Proc. Am. Acad. Arts and Sciences 4: 124. 1860) in the Curtis Herbarium (Bonin Isles) is so pressed as not to show the base of the spore sac; peristome truly sulcate; spore sac reddish brown with a grayish < o P] ATI-'.

Other plants from the type collection in Washington are similar with inner peridium blackish brown with a grayish powder. We have a fine specimen from New Caledonia sent us by Patouillard (as G. plicalus = G. biplicaius) with strongly sulcate base to the spore sac, the stalk about 4 mm. long; spores spherical to a little irregular, distinctly warted, 4-6/u thick; capillitium straight, up to 6.5m thick. It is probable that G. plicatus and G. triplicates are the same, as Patouillard thinks, and both are certainly very near G. pectinatus. The deep and regular sulcations on the base of the spore sac are a striking character that we have not seen exactly duplicated in G. pectinatus. We have seen Lloyd's abundant specimens of G. plicatus from Australia and South Africa, but have not seen the type. Illustrations: Cunningham. Trans. N. Z. Inst. 57: pi. 9, fig. 27. 1926. Cunningham.

Herb.) the spores are smaller and less distinctly warted, 3.8-4.8^ thick. The plant is also well represented in Sydow's Mycotheca germanica, No. 1449 (Path, and Myc. Herb., Washington). The plant is rare in America and is not reported from the southeastern states. Lloyd reports it from Maine and Texas, and Morgan from New York. Illustrations: Berkeley. Grevillea 2: pi. 16, fig. 2.

Rabenhorstii Kunze Plates 75 and 115 Like G. pectinatus, except smaller and with a short stalk and less separable mycelial layer and smaller spores. A typical lot of this form is No. 5020 of E. Bartholomew's Fungi Columbiana (Calloway, Nebraska; J. M. Bates, coll.). These have 5-6 reflexed rays with trashy mycelial layer attached, the thin brown fleshy layer also present; spore sac suboval, very short-stalked, smooth, dark brown, mouth elevated, strongly sulcate. Spores medium dark, minutely warted, spherical, 3.7-4.4u, with a visible oil drop. Another lot of Bates' plants from Nebraska are in the New York Botanical Garden (from Lloyd Herb.). The outer surface is covered with sand, the spore sac blackish with a whitish or brown powder. A less typical lot is from New Jersey (Newfield; Earle, coll., at N. Y. Bot. Gard. Herb.) . This lot has the rays slightly hygroscopic and in one of the plants the spore sac is yellowish buff color. Another plant of this lot is the one shown by Lloyd in his Geastrae, fig. 27 a. The spores of this particular plant are like those noted above, minutely warted, 3.7-4.5;*. A plant about intermediate between pectinatus and Schmidelii is at the New York Botanical Garden Herbarium (Underwood, coll.; Kirkville, N. Y.). The spore sac is buffy and the stalk very short. European G. Schmidelii as distributed by Torrend (Mycotheca Lusitanica, in Path, and Myc. Herb., Washington) is like our American plant and like the types of G. Rabenhorstii. Three plants sent us for examination by Patouillard (Herb. Mus. Paris; Barla, coll.) as G. Schmidelii are somewhat worn specimens of the minimus form of G. coronatus. The spores are spherical, warted, 3.7-4.6^. In freshly opened plants collected by us in Warrenton, Va., the fleshy layer was nearly white; spore sac drab. On drying the fleshy layer turned brown and cracked considerably. . Spores of the type material of G. Rabenhorstii (Fungi selecti exs., No. 10, in Path. and Myc. Herb., Washington) are spherical, distinctly warted, 3.8-5^, a few up to 5.5^. Geaster elegans Vitt. is very near G. Schmidelii, the only obvious difference being the entirely sessile spore sac and larger spores of the former. These characters are shown by plants in Torrend's Mycotheca Lusitanica, No. 78 (Univ. Wis. Herb, and U. N. C. Herb., as G. elegans), and in his Fungi selecti exs., No. 79 (in the same her- barium, as G. minimus) ; also in the Herbarium of the University of Paris (from Tu- lasne Herb.). The spores of the last mentioned are minutely but distinctly rough, 4.2-5.5^ thick (pi. 116, fig. 2). The plant is not known from America. This would seem to run into a saccate form, apparently quite sessile as shown by a distribution of 11 good plants by J. Kunze, Fungi selecti exs., as G. striatus DC, from the same place as his G. Rabenhorstii and also like that in growing in Picea excelsa needles; mouth, peridium and all else same except that the outer peridium is saccate or flat and inner peridium with no obvious stalk.

Geaster Hariotii Lloyd Plates 68 and 115 Rays about S, spreading about 3 cm., pliable, not hygroscopic, revolute or in part expanded, the center concave below and elevating the spore sac; outer surface entirely covered with earth or trash held on by flocculent mycelium which may in time be partially shed in flakes. Fleshy layer dark brown, cracking and seceding in places. Spore sac 1.5 cm. broad, subglobose, sessile, dark brown to black, distinctly pitted and rough to asperate with small points, but not truly warted or tomentose. Peristome truly sulcate, mouth elevated and becoming fimbriate. Spores (of plant from Porto Rico) spherical, dark, faintly rough under very high power, 3.5-4m thick. As Lloyd does not mention a rough surface to the peridium (Myc. Notes, p. 311), we had referred our plant to this species with some doubt until the recent receipt from Patouillard of a specimen from Brazil that had been seen by Lloyd and which Patouillard designates as an "original specimen." This is exactly like our plant except that the surface is somewhat less conspicuously rough; rays not rigid; spores spherical, nearly smooth, 3-3.6ju thick, often with a visible oil drop. Capillitium threads straight, encrusted, up to 6.5/u thick. Under G. Archeri Lloyd has two collections, one from Ceylon (Petch, coll.) and one from Victoria (Winkler, coll.). They are not that species, but pale forms of G. Hariotii. The mouth in each case is darker than the granular or spongy peridium; peridium clay-brown to brown; mouth truly sulcate; outer surface densely flocculent and with trash as in G. Hariolii.

Spores (of a plant from Lincoln, Nebraska), spherical, distinctly warted, 4.5-6.5/n. Capillitium threads straight, up to 5p thick. A plant of the Mississippi valley and westward, seeming to prefer sandy soil. It is well marked by the conspicuous granules on the spore sac, which are much coarser than the fine powdery particles on the sac of G. coronatus and G. leptospermus. This species varies to a form with lax and pliable outer peridium like that of G. mammosus and G. Schmidelii. See, for example, one plant among a typical lot of G. asper from Dakota at Washington (Brenckle, Fungi Dakotensis, No. 35, in Path, and Myc.

Spores (of plants from New Jersey, Ellis, No. 3472) spherical, faintly warted, 3.5-4m thick. Capillitium threads wavy, up to 6.5m thick. A plant of sandy soil in Europe and America and evidently rare. It is the plant distributed by Ellis as No. 110 in his North American Fungi (as G. mammosus), and a letter to Ellis from Morgan at the New York Botanical Garden states this to be the same as his umbilicatus. The species is known from New Jersey (Ellis) and from Florida (Lloyd). Morgan thinks that G. Smilhii Lloyd (Geastrae, p. 21) is the same, but Cunningham does not agree with this. It should certainly occur on our North Carolina coast. The rays in this species while distinctly hygroscopic are more delicate and pliable than in G. mammosus and much more so than in Astraeus. From G. Drummondii (G. modulus) and G. asper the plant is easily separated by the delicately and softly furfuraceous, not warted or asperulate spore sac, and by the smaller spores. From G. Schmiddii, which is very near, it is separated by its hygroscopic and not revolute rays and by the sessile spore sac. The spores of the two are very nearly alike. Lloyd has seen the type of G. ambiguus and thinks it different from G. striahdus, to which he refers the present plant (Myc. Notes, p. 311). Geastrum minimum Chev. (Fl. Gen. Env. Paris 1: 360, pi. 10, fig. 3. 1826) does not look much like this species. It has a distinct, slender stalk, though short, and that is why Chevallier considered it new. He gives the sessile G. badium Persoon under his species as a form alpha. Hollos considers G. badium and G. umbilicatus the same as G. clegans Vitt. (which see under G. Schmiddii). From the description there is no reason to think that G. striatus var. minimus Wallroth (Fl. Crypt. Germaniae 2: 400 (No. 2274)) is the same as our American plant above described. He refers to Chevallier's G. minimum as the same. Illustrations: Hollos. 1. c, pi. 9, figs. 15-17 fas C. ambiguus). Lloyd. Myc. Notes, p. 71 (as G. striatulus). Also copied on pi. 98, figs. 3, 4.

Sckweinfurlhii Hennings Plates 115 and 116 At the New York Botanical Garden Herbarium are two good plants from Bris- bane, Australia (Herb. Massee) which appear to truly represent this species. The plants are : Hygroscopic, rigid; fleshy layer blackish; outer surface covered with sandy humus; spore sac small, subglobose, sessile. One plant has the inner peridium 12 mm. broad, spiny-granular; mouth blackish, 12-ridged. Spores faintly rough, spherical, 5.4-6.5^. 138 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA The other has the inner peridium 9.5 mm. broad, pulverulent-granular; mouth creamy gray, 19-ridged. Spores faintly rough, 4.5-6.5/u. Inner peridium of both creamy gray (pale leather color). Type plants of G. involutus from St. Domingo at the New York Botanical Garden show that no important difference can be made out to distinguish it from G. Drum- tnondii. The appearance is identically like that of the plant with spiny peridium, except that the mouth is not dark. The spores are the same, minutely warted, 4-5m thick. The inner peridium is asperate and the mouth beautifully sulcate with 12 or 14 ridges. Hollos gives G. avellaneus Kalch. as a synonym of this species, and both as synonyms of G. ambiguus Mont. The former was published only as a figure, with no written description. The spore sac is shown as white and not dotted; the outer per- idium evidently hygroscopic, in one case folded over the spore sac, its outer surface ochraceous with some earth attached; mouth truly sulcate.

Outer peridium as in Geaster, coriaceous, pliable, splitting in a stellate way with segments expanded or reflexed; inner peridium with several short stalks (rarely one by coalition), membranous, papery, opening by several to many mouths (rarely one). Columellas several, slender. Capillitium threads free, simple or nearly so. There is only one species of this genus known, as it has been shown by Patouillard that Geaster columnatus Lev. is a synonym (see Lloyd, Myc. Notes, p. 156) . Myriostoma coliformis Corda Plate 117 Plants subterranean until dehiscence, lobes usually 5-7, acute; fleshy layer thin, brown, adherent at first but wearing away; outer layer nearly smooth, usually with adherent sand or trash. Inner peridium subspherical to compressed, 1.5—5 cm. broad, roughened by minute points and lines, silvery brown. Mouths small, fibrous to lacerate. Spores (of plant from Lloyd Herbarium) spherical, strongly warted with irregular pale warts, 4-6m thick, rarely abnormal ones up to 8/z. Capillitium threads long, slender, tapering at both ends, entirely free from the peridium and columella, about 2-5/i thick, with a thick wall which often closes the lumen. This species has a wide but erratic distribution in this country and in Europe. It is not known from the Carolinas, but has been found in both the northern and southern states.

Fruit bodies growing just beneath the surface or partially exposed; outer peridium thickish and volva-like, composed of two layers, an outer of loosely interwoven white threads which grow around and enclose many particles of sand and trash and a much thicker inner layer which is watery and subtranslucent when fresh and composed of large, thin-walled, parenchyma cells which dry up and collapse at maturity to form a thin coat on the inside of the outer peridium, the lower part of the outer peridium split- ing awav at maturity and remaining in the ground, the upper part with the thin, firm, inner peridium attached, breaking away and becoming free; inner peridium opening by a small basal mouth to liberate the spores, which are spherical and warted. Gleba composed of very minute, irregular, anastomosing chambers which are separated by clusters of basidia and a very little trama; basidia much as in Lycoperdon, with four slender sterigmata; capillitium threads extending inward from the inner peridium, sparingly septate and slightly branched, at maturity breaking up into small sections. Subgleba none. Up to the present the internal structure of this genus has not been known, so that its proper position in the system was obscure. It is now apparent, it seems to us, that the genus is a highly specialized member of the Lycoperdaceae. The best evidence to this effect are the basidia, which are obviously of the Lycoperdon and Bovista type and quite different from the Astraeus and Calostoma type. Moreover, while the chambers are very small and the hymenium poorly defined, there is an obvious resemblance to the Lycoperdaceae in these characters also. Three species are known from the southeastern states. Several others are known from the West. Lloyd extends the genus to include several species without the peculiar dehiscence and inverted mouth (Myc. Notes, p. 121, pis. 6 and 7; Myc. Notes, p. 1167). A new genus, Abstoma, has been established by Cunningham (Lycoperdaceae, etc., p. 206) to cover a single endemic species from New Zealand. It is very near Disciseda, differing from it essentially only in the absence of a definite mouth, both peridia wearing away gradually from the attrition of wind-blown sand, etc. Key to the Species Spores without a pedicel, or rarely with a short one Spores 3.6-5,* thick D- Candida Spores 5.5-9.5,1 thick D. subterranea Spores with a pedicel up to 12.5m long or rarely longer D. pedicellata Disciseda Candida (Schw.)

Morgan Plates 31, 78,79, 99 and 118 Plants single or cespitose, compressed globose, with a single rhizomorph-like root when young and fresh; 0.5-2 cm. thick, 2-3.5 cm. wide before maturation; 0.8-1.5 x 140 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 1.5-2.5 cm. when dry; growing in the soil and partly exposed when fully grown; sur- rounded until maturity by a thickish cortex (outer peridium) the upper and thicker part of which remains attached to the inner peridium by a layer of spongy fibrous material, the lower part tearing irregularly from the upper and separating more or less completely from the inner peridium and remaining in the ground as broken and inconspicuous fragments. The upper part with the inner peridium attached is now free and is easily knocked out of the cup-like lower part by rain, etc., turning over so that the exposed part of the inner peridium is now above. A small torn hole now appears at the place of attachment of the stalk, in the center of this upturned base, and the spores begin to escape. The cortex is a sand case held together by the woven white mycelium. The inner peridium is rather firm and rigid, pale brown then silvery gray to slate gray in age, minutely granular or scurfy on the exposed (lower) part, densely scurfy above under the cortex. This thick spongy tissue above and thin granular layer below are the remains of a watery translucent layer, 0.6-1 mm. thick which lay between the more fibrous layers in youth. The inner peridium is very indistinct in sections when fresh, becoming conspicuous on maturing and drying. The whole plant shrinks to scarcely more than half its original size upon drying. Glebal chambers extremely minute, 5-25/1 wide, but often longer; no definite tramal plates are formed, as in Lycoperdon and Scleroderma, but the basidia arise from irregularly anastomosing strings of threads and the chambers are very irregular. Gleba white when fresh, changing as the plant matures through yellowish olive to brown, at times faintly purplish. There is no sterile base. Spores (of No. 5967) brown, at times with a tint of purple, globose, 3.6-4.4/i thick, warted, and with a short pedicel (mucro). Capillitium threads 3-5/i thick, irregular, not rarely branched, extending inwards from the walls of the peridium; after maturity breaking up into short pieces. Basidia (of No. 6092) short-pyriform, 6-7.4 x 9-14/1, usually with 4 slender apical sterigmata of equal length. This little plant is easily recognized by its peculiar habit of dehiscence and reversal. It is not at all rare in pastures, the fresh, nearly mature plants appearing in mid-summer, the liberated plants obvious in fall and winter. The earthy color makes the plant in- conspicuous and it has seldom been reported. The type of Bovista Candida Schw. in the Schweinitz Herbarium is this species, as Lloyd says (Myc. Notes, p. 93), but it is so pasted on its sheet as to obscure its char- acters, and the spores, while of the same size, are less rough than in our plants and in the co-type of B. circiimscissa B. & C. The spores are 3.7-4.4/1, nearly smooth. The plant may have been collected before fully mature. The capillitium threads are unmistak- ably those of this genus, made up of irregular fragments, 3.3-4.6/1 thick, rather rarely branched. We have some Chapel Hill specimens (as No. 6092) with spores less warted and approaching those of the type of Bovista Candida. The co-type of Bovista cir- ciimscissa in the Curtis Herbarium (Blake, No. 164) is like our No. 7115. The spores are warted 3.9-4.6/1 thick. The form we have described above is the Chapel Hill plant which is typical as described by Hollos for the European plant, though running smaller than Morgan's drawings. We have a collection from Asheville (Beardslee) which are 2.5 cm. broad, counting the open cup. They are a brighter brown than our plants, about snuff-brown, but the spores and other characters are the same. Illustrations: Clements. Minnesota Mushrooms, fig. 88 (as Catastoma).

The size of the plant is therefore not a constant distinguishing feature, and the larger spores (5.5-9.5/z) must be finally relied on for determination. The present species was described from Dakota and seems to be common in the middle and far west (see Lloyd, Myc. Notes, p. 122; Morgan, 1. c, p. 143). We have a good specimen from Denver, Colorado (Bethel, coll.), and have also seen a specimen from Canada kindly sent us by Dearness. These plants are about 1.8-2.8 cm. broad, subspherical or depressed; in the Canadian plant the outer peridium covering about one-half of the inner; in the Denver plants forming only a disk opposite the mouth. Our collection from North Island, South Carolina, is apparently the first collection from the southeastern states. As this station invades the territory of D. pedicellata, which was plausibly separated from this species by the different regional distribution and pedicellate spores, confidence in a real specific difference is distinctly reduced. We can now make out no difference between the last two except the presence of a conspicuous and persistent pedicel on the spores of D. pedicellata. The North Island plants are smaller than the Denver and Canadian specimens and, like the former, are not at all or scarcely depressed and retain only a small, sandy, basal pad representing the outer peridium. Both the Denver and South Carolina specimens, as well as Rav- enel's Xo. 15 (D. pedicellata) at Philadelphia, show several small openings in the inner peridium in addition to the apical one. These may be due to insects but appear natural. As Petri gives the spores as only 4.5-5.3^, it is doubtful if he had this species. Disciseda verrucosa Cun. (Lycoperdaceae, etc., p. 205) should be compared with this species. From the description it is very close if not the same. 142 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Illustrations: Hollos. 1. c, pi. 22, figs. 20-24; pi. 29, fig. 36 (all as D.

C, and have compared it carefully with Ravenel's Bovista nigrescens, No. 15, as represented in the Herbarium of the Academy of Natural Sciences of Philadelphia (ex Herb. Geo. Martin). Morgan es- tablished the species on a South Carolina specimen of this series from Ravenel. The Ravenel plant has spores irregularly warted, spherical, 7-9/x thick with pedicels up to 6/i long, in all respects like those mentioned above; capillitium threads fragmented, sinuous, up to 5ju thick, with thick walls. A plant received from Lloyd without locality data differs from South Carolina plants in somewhat larger spores (7.4-9^) with more cylindrical warts and distinctly longer pedicels (12-20/x). Otherwise the differences are inconspicuous and probably represent a regional variety. For comparison with D. subterranea see that species. For references see Lloyd, Myc.

Plates 80 and 117 Fruit bodies small, crowded together in large numbers on a common, firmly leathery stroma about 1-2 mm. thick which superficially covers the substratum. Individual fruit bodies touching each other or here and there as much as 4 mm. apart; about 6-10 mm. thick, flattened above; at maturity the flattened top becoming pale and cracking into pieces which fall away, leaving the firm, deep brown, leathery sides to form a cup only slightly lower than the puffball within. Inner peridium paler brown, thin, pliable, opening by a small apical pore, collapsing gradually as the spores escape and finally settling into the bottom of the cup. Spores yellowish brown under the microscope, spherical, minutely warted, 4-5. 5m, sometimes with a small mucro visible. Capillitium very scarce, pale, threads long or fragmented, branching, thick-walled with lumen almost closed, usually surrounded by remnants of collapsed threads, about 4.8-1 1/u thick, with a rough wall. The type is from Cuba and it is also known from the Bahamas (Inagua, Andros, Long Island) and Guadaloupe. As Lloyd mentions, the mouth is not protruding as shown in Fischer's figure. Our specimens, while ample, do not show stages young enough to determine the internal structure in youth, but the arrangement of the capillitium in a mount suggests that there were chambers. We therefore place the genus provisionally in the Lycoperdaceae. Illustrations: Fischer. Englerand Prantl, Pflanzenfamilien ll: 323, fig. 167 D. Lloyd. Myc. Works, pi. 15. Bahamas.

The North American (Albany) record for this little known genus, as given in Saccardo, is a mistake, as noted by Lloyd, the plant really being found in the district of Albany at the Cape of Good Hope (Leveille; Ann. Sci. Nat., 3rd ser., 9: 129. 1848). This leaves the type species, B. congregala, known only from South Africa. Of the other two described species, B. gnadalupensis, is almost certainly Diplocystis Wrightii. For discussion and reference to figures of Broomeia see Lloyd, Myc. Notes, p. 917. The genus Broomeia is distinguished from Diplocystis by a uni- versal volva covering a crowded group of small peridia which are seated on a more or less elevated, common base. ARACHNIACEAE Fruit bodies exposed; peridium single, very thin, crumbling at maturity. Gleba with distinct chambers lined by the hymenium, these chambers forming at maturity a mass of minute, separate, hollow peridioles which crumble and escape like grains of sand. Capillitium and sterile base none. This family is most nearly related to the Lycoperdaceae, from which it differs in the simple peridium, absence of capillitium, and presence of peridioles. The peridioles in Pisolithus are of a very different nature, being solid masses at all stages and without a hymenium. We are including in the family only the genus Arachnion, as Arachniopsis and Eolocotylon are not yet well enough known to be placed. If the former genus is good and Long's description is accurate, it is very different from Arachnion, and if Lloyd is right in thinking it the same as Arachnion (Myc. Notes, p. 1134) it need not be considered. Eolocotylon may be related to Arachnion, and if so the family description will have to be modified by the omission of peridioles. ARACHNION Schw. This genus is characterized by the peculiar nature of the contents of the peridium at maturity. It is filled not with the typical gleba consisting of capillitium and spores that are found in the Lycoperdons, but with a mass of granular particles like grains of sand. They are grayish or ash-colored, and look like a mass of sandy earth. These granules are peridioles or little sacks containing the spores. Each particle consists of a woven web of hyphae enclosing a minute chamber around the walls of which are borne the basidia pointing inwards, thus showing a close relationship to Lycoperdon. In youth the structure is like that of Lycoperdon, the empty chambers being separated by tramal plates of delicately woven hyphae. The peridium is smooth, not double, very thin and fragile, and breaks easily into small particles at maturity, exposing the granular contents. There is no sterile base. Originally there was only one species recognized, A. album, described by Schweinitz from this state in 1822, but other tropical and austral species have since been added. Long has described a genus Arachniopsis from Texas as closely related to Arachnion (Mycologia 9: 272. 1917), but Lloyd, who saw the types, thinks they are not different. Eolocotylon from Mexico and southern Texas is a genus apparently related (Lloyd, Myc. Notes No. 21 : 254, pi. 73, figs. 5-8. 1906. Also No. 22: 271. 1906). Literature Lloyd. The Genus Arachnion. Myc.

Plates 81 and 118 Plants with the fruiting body above ground, irregularly spherical with a more or less pointed base which extends into a small toughish root, lower surface more or less grooved or pitted, surface smooth, dull white until maturity then buffy when dry, or yellowish if water-soaked. Peridium thin, 0.5 mm. thick or less, the same thickness all around, toughish. Gleba pure white then gray or brownish olive at maturity, composed of a large number of minute empty chambers lined by a hymenial layer, apparently made up only of basidia, the context between the chambers consisting of a loose weft of delicate, interwoven hyphae. At maturity this loose tissue breaks down and leaves the chambers as distinct granular particles which contain the spores and fall apart like sand at maturity or decay into a sordid mass in wet weather. This structure indicates a close affinity to Lycoperdon. The peridium has no definite opening but falls to pieces slowly by decay or usually by the attacks of grubs (the larvae of the fire-fly playing a large part). Odor none until ripe, then decided and nitrous, resem- bling somewhat that of Bovistella radicata and some Lycoperdons. There is no capil- litium or columella or sterile base. Spores (of No. 730) brown under the microscope, smooth, short-elliptic, with a decided mucro or short stalk about 1/i long, though sometimes twice the length of the spore, 3.2-1.3 x 4.3-5.5/i- Basidia clavate, 3.7 x 11/*, apparently bearing only one mature spore at a time though two or four sterigmata may be seen in the young state; sterigmata very peculiar, a long, very slender part remaining attached to the basidium and a shorter, stouter part falling off with the spores as its stalk. It was from this state that Schweinitz first described this interesting plant. It is plentiful in Chapel Hill in summer and seems to prefer cedars, but it also grows in deciduous groves and in open places and we have found it in abundance in flower beds. We have also found it at Hartsville, S. C. It is widely distributed in the eastern United States and, according to Lloyd, in other parts of the world. It has been found only once in Europe (Italy).

SPHAEROBOLACEAE Characters of the Genus Sphaerobolus SPHAEROBOLUS Tode Minute plants, growing on rotting wood (common form), on earth (Alabama) and on dung of herbivorous animals (Mississippi, Africa). Fruit bodies subspherical when on wood, breaking through without an exposed mycelium or less often seated on the wood and surrounded and covered when young by the white mycelium. Peridium of several layers, an outer, thick layer of woven hyphae, much like the mycelium; next a pseudoparenchymatous, gelatinous layer (lacking in 5. iowensis), a thin filamentous layer, and, finally a thick highly specialized inner layer of long, densely packed, pris- matic cells radially arranged. This last is sometimes called the receptaculum. The spore-bearing gleba is an inner ball of fertile tissue which at maturity is indistinctly divided into areas by thin sterile plates. In youth these areas may be hollow and lined with a distinct hymenium or stuffed and without a distinct hymenium, depending on the species. However, even in species with stuffed chambers, the basidia are not indis- criminately scattered, but are arranged in definite groups. This with the obvious chambers of S. iowensis clearly indicates a relationship with the Lycoperdaceae, rather than the Sclerodermataceae, as pointed out by Miss Walker. The dark, shining and viscid glebal ball is shot out with force at full maturity by the sudden evagination of the receptaculum. Spores smooth, sessile on the oblong basidia. Gemmae capable of sprouting are also found in the gleba. This is the only genus of the family. About eight species have been described but the validity of several of them is doubtful (see Saccardo, Syll. 7, p. 46, and 17, p. 216. For 5. impaticus Boud. see Hollos, p. 185).

Plates 82 and 117 Plants arising from within the soft wood or bark, and pressing through to expose its upper surface or the greater part; subspherical, about 1.5-2 mm. thick, at first dull ochraceous from the surface color, then whitish from the cracking of this superficial layer into flakes; soon after exposure the little sphere opens at the top in most cases by four to seven stellate lobes and the outer, translucent-white layer (receptaculum) of the gleba suddenly reverses itself outward and throws the little central flattish ball containing the spores to a distance of several feet (Miss Walker reports a height throw of over 14 feet). The reversed and evaginated receptaculum now appears as a watery white sphere sitting on the lobes of the outer peridium. The ejected ball is slippery, smooth and very dark chestnut brown, looking like a miniature horse chestnut seed. Within it is divided into sections by delicate walls and in these areas are borne the oblong basidia, 4-4.8/* thick, with four to six, rarely eight (up to nine in Pillay's form), sessile spores. According to Miss Walker, these areas are never cavernous in their development, and there is no definite hymenium. She gives the following cytological facts for S. stellatus. All cells of the fruit body are binucleate; the two nuclei fuse in the young basidium; the fusion nucleus divides to form 4-8; the nuclear walls disappear ; the chromatin center of a nucleus enters each spore, and where there are less than 8 spores, some of these granules are left behind; the young spores are uninucleate, the older ones may be binucleate. Spores smooth, unevenly oblong, 3.7-4.8 x 7.4-10^. Mixed with the spores are certain irregular densely filled cells (gemmae) formed by the hyphae which are also capable of sprouting to form new threads. The entire ball of the gleba is said (Fischer) to sprout without breaking up, sending out many hyphae from the gemmae and spores within. For references to illustrations and literature see under the genus. Misses Walker and Andersen give evidence that the discharge of the bolus in Sphaerobolus is due to the rapid transformation of glycogen into sugars, followed by a great increase in osmotic pressure in the cells of the peridium. Miss Walker has grown four forms of Sphaerobolus in pure culture and obtained abundant fruiting. Her last paper gives further details of structure and behavior and proposes a new variety of 5. stellatus and a new species. We are including her descriptions of these below. 5112.

It is to be noted that Cunningham (1. c, p. 16), speaking of Australian plants that he refers to S. stellatus, described the gleba as having "several" cavities separated by thin walls and says that these cavities are lined with hymenium. Whether by several he means many is not indicated by the figures. However, as his plant has the gelati- nous layer in the peridium, it does not agree fully with 5. iowensis. Type locality: Hunters, Iowa, on old coniferous boards. PLATE 82 J- Sphaerobolus stellatus. No. 7530 [above] Scleroderma ceaster. Stafford Co., Va. From Doctor Howard A. Kelly. Reduced TYLOSTOMATACEAE Plants formed underground, emerging at maturity and consisting of a tough, fibrous, stalk bearing the globular spore sac, the outer wall of which (in Tylostoma) consists of a thickish, sandy layer which either breaks up and falls away soon in flakes or persistently adheres and slowly wears away. The inner layer is a thin, tough, rather firm, persistent membrane which contains the unchambered homogeneous gleba without tramal plates; the spores escaping by a definite apical mouth (at times several) or by an irregular or circumscissile dehiscence. Capillitium present, of varied char- acter, arising from the entire surface of the inner peridium. Basidia club-shaped with 4, irregularly scattered, nearly sessile spores. The outer peridium in Queletia has not been described in detail. Lloyd (Myc. Notes, p. 135) say's that it is "apparently a thin white coat that breaks up into granular particles and mostly disappears." Six genera are included in the family by Miss White, five of which are from America. Only two of these, Tylostoma and Queletia, are known east of the Mississippi. Chlamydopus has been found in New Mexico and Washington, Dictyocephalos in Colorado, Battarrea in several western states, and Sphaericeps is known only from Angola in western Africa. See Miss White for descriptions of these. For convenience we include in the key all the genera of the family. With some changes it is copied from Miss White. Key to the Genera Peridium opening by an apical mouth No free volva present; stem not flaring above Tylostoma (p. 149) Free volva present; stem flaring above Chlamydopus Peridium circumscissile Peridium nearly plane below, dehiscing around the basal margin Battarrea Peridium spherical, dehiscing at the equator Sphaericeps Peridium opening irregularly Peridium easily separating from the stem; capillitium not embedded in a tissue . . Queletia (p. 158) Peridium firmly attached to the stem; capillitium embedded in a tissue Dictyocephalos TYLOSTOMA Pers. Mycelium subterranean, composed of delicate, white, much branched strands which bear here and there white, sclerotium-like balls of various sizes, these developing (apparently slowly) into the full sized buttons. Peridium composed of an outer sandy case formed of delicate flocculence holding the earth,— in which in the button stage is also included the unextended stem,— and an inner, very thin layer formed of delicate, interwoven hyphae which, without apparent change, turn inward and continue as the elements of the gleba. Stalk cylindrical, tough and firm, with a central column of delicate soft, white, cottony tissue; surface usually brown and more or less marked with scales and fibers. Capillitium abundant, arising from the entire inner surface of the peridium. including the base, pale to nearly hyaline, frequently septate, much branched, not rarely with cross bar connections as if anastomosing had occurred (but probably only a method of branching) ; with walls irregular in thickness in the same thread, in places closing the lumen; tapering tips lacking, the ends appearing abrupt as if broken. 149 150 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Basidia short-clavate, usually 4-spored, peculiar in having the spores scattered over the surface. There is no trace of a hymenium or of tramal plates, the basidia being dis- tributed equally on the interwoven threads of the homogeneous gleba. Spores spherical or subspherical, rust colored to cinnamon, warted or smooth. The genus is distinguished from others of the family by the smaller size and (except in Chlamydopus) by the definite, circular, smooth or fimbriated apical mouth (or mouths) by which the inner peridium opens to liberate the spores. Miss White reports seventeen species from North America, eight of which are described as new. Tulostoma is the spelling used by some authors, and Tulasnodea Fr. is a synonym. In the unexpanded button the stem is a short plug enclosed in the outer peridium. When the expanded plant dries the stem shrinks considerably in thickness and draws away from the outer peridium which surrounds it above. This leaves a space between the two, and the descending margin of the outer peridium which is often acute is the so-called collar around the stem apex. If moistened after drying the stem swells back to its original size and fills the collar again. The spores are often somewhat collapsed when dry so that even those that were smooth when fresh may appear angular or nodulated. In such cases they should be plumped out by an application of KOH or lactic acid. Literature Bessey. Growth of Tulostoma mammosum. Amer. Nat. 21: 665. 1887. Lloyd. Myc.

Spores (of plant from North Dakota) spherical, very faintly warted, 3.8-4.5 x 4-5. 5m- Capillitium threads somewhat irregular, occasionally branched and septate, up to Sju thick. Lloyd thinks that the typical European form of this species does not occur in America, but we find plants with dark mouths and exactly the microscopic characters of the European plant. They differ from T. simulans and T. floridanum in the darker mouth area and much smoother spores. We have examined a typical specimen of T. mammosum from Europe with a dark mouth area (A. Vill, Fungi bavarici, No. 926) and find that it agrees almost perfectly with the American plant: the spores are almost smooth, 4-5. 5ji thick, and the capillitium threads agree. Another plant like it (Schlesien; Dresler, coll., as T. brumale) at the New York Botanical Garden has similar spores. Illustrations: Batsch. Elench. Fung. 2: pi. 29, fig. 167 (as Lye. pedunculalum).

The sandy cortex is persistent for a long time and slowly wears away above and even more slowly below to expose the brown or whitish inner peridium which opens by a single, small, apical mouth with a smooth edge, at the top of a little tubular elevation which in a few of our plants is surrounded by a slightly darker area. 152 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Stem 1.5-3 cm. long, 3^1 mm. thick when fresh, 1.5-2.5 mm. thick when dry, the base slightly enlarged by the soft, white, cottony mycelium which brings up a little earth; surface often nearly covered with reddish brown lacerate scales which wear away gradually on exposure and in age are represented only by the inherent parts; in some plants of the same colony the reddish brown cortex instead of being lacerated may be more even and adhesive and form a cracked and mottled outer layer of the stem which may persist for a long time; color under the scales buffy brown, becoming dull dark brown with age; body of the stem longitudinally striate when dry, deeply inserted in the outer peridium and on drying shrinking away from the peridium and leaving the usual collar which may or may not have a thin, free margin. Context of stem white, fibrous, brittle when dry, containing a central cylinder that is partly filled with delicate, silky fibers. Spores (of No. 87) globose to subglobose, yellowish cinnamon in color, closely set with thick, coarse, pale warts, 4.2-6 x 4.5-6.8/i thick counting the warts, which are up to a fraction over lju long; in KOH solution appearing spinulose with a hyaline material between the spines. Capillitium threads buff, moderately branched, septate, somewhat swollen at the joints, 4.5-6.5/* thick. This species is reported by Lloyd from Ohio and Texas. It may be considered the southern form of T. mammosum, from which it is separated by the more persistent outer peridium and by the strongly warted spores. There is also much less tendency to a dark mouth area, though in our No. 87 there is a somewhat darker diffuse area around the mouth. For a comparison with T. floridanum see that species. The present species is peculiar in the paleness of the warts on the spores and their vagueness in surface view. This seems to be due to the abundance of the nearly colorless amorphous material which makes up the greater part of the warts and in places fills the space between them. Examination of T. mammosum in Ellis and Everhart's North American Fungi, No. 2734, shows it to be exactly like the Chapel Hill plants. The spores are 4-6/u thick, distinctly rough, subspherical; capillitium threads 3-6yu thick, thin- to thick- walled, swollen at the septa. Their T. pedunculatum (Fungi Columbiani, No. 1888) is not different. Spores 4-6/* thick, subspherical, distinctly rough. Capillitium threads 3-7/x thick, thin- to thick-walled, swollen at the septa. The T. mammosum of Curtis' list is probably this species. Illustrations: Lloyd. Myc. Works, pi. 79, figs. 2 and 3 87. On a dry, pebbly hillside among cedars, April 1903, and April 1904. 5930.

Tylostoma floridanum Lloyd Plates 83 and 119 We have examined specimens of the type collection of this species from the Lloyd Herbarium. The plants are small and slender; spore sac about 5-7 mm. thick. We find the spores to be spherical to oval or irregular, 4-6 x 4.8-6. 8n, distinctly warted with elongated, irregular warts. Capillitium threads irregular, septate, branched, up to 8.5/i thick with thickened walls. Lloyd's description follows (The Tylostomeae, p. 18): "Peridium dark castaneous color, with a small, tubular, circular, protruding mouth. Cortex separating imperfectly, particles adhering to the peridium, thickened and sub- persistent below. Stem slender, dark reddish brown, subsmooth, substriate with no trace of scales, white within, hollow with central fibrils. Capillitium subhyaline, some- times wavy [written waxy, in error?] with septa both swollen and even. Spores 5/i, strongly asperate." This plant is nearest T. simulans, from forms of which it can hardly be distin- guished. The spores, while warted in about the same way as in T. simulans, show the warts much more clearly in surface view. Other characters mentioned by Lloyd, as slender, dark stem and colored peridium can be nearly or quite matched in simulans or mammosum. Lloyd has described another species, T. pygmaeum, from Florida (The Tylostomaceae, p. 16, pi. 78, figs. 3, 4) which, from the description, differs from T. floridanum only in the unimportant character of color. Illustrations: Lloyd. Myc. Works, pi. 80, figs. 1 and 2. Florida. Lloyd. (Lloyd Herb., type, and U. N. C. Herb.) Tylostoma verrucosum Morg. Plate 119 This rare species has been found but a few times. Morgan described it from Ohio, and Lloyd reports it from Texas (Long, coll.). We have seen authentic specimens collected by Lloyd and determined by Morgan, and find the spores to be spherical to irregular, distinctly warted, 4-6^ thick. Capillitium threads up to 8^ thick, irregular, swollen at septa, walls irregularly thickened. The original description by Morgan is as follows (Journ Cin. Soc. Nat. Hist. 12: 164): "Peridium depressed-globose, thickish, becoming firm and rigid, with a dense brown cortex of minute persistent scales and warts ; the mouth small, circular, prominent, entire. Stipe long, slender, with a surface of brown lacerate scales, internally white, with a central pith of long loose fibers; the mycelial bulb large, irregularly depressed- globose. Threads of the capillitium long, slender, about as thick as the spores, hyaline, branched; spores irregularly globose, minutely warted, pale brown, 5-6/u in diameter. 154 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA "Growing on the ground in rich soil in woods." Lloyd says that the species is very close to T. squammosum of Europe, from which it differs in verrucose cortex and more robust habit. Illustrations: Lloyd. Myc. Works, pi. 76, figs. 3-5. Morgan.

Tylostoma Finkii Lloyd Plates 85 and 119 Spore case depressed-globose, 0.7-1 cm. high by 0.9-1.4 cm. wide, color when fresh ochraceous to tan where not covered with sand, fading when dry to a mouse-gray with a tint of salmon (under the sand) ; outer peridium consisting of a rough sandy cortex which slowly wears away above and is even more persistent and somewhat thicker below where it may appear with an obscure margin like a cup after the wearing away of most of the upper part; mouth or mouths (1-4 in number) circular or elongated and irregular, elevated (up to 0.8 mm. high) or scarcely so, concolorous with the peridium or slightly lighter, the margin eroded or nearly smooth, and not surrounded by a fibrillose pad. Stem 1.8-2.7 cm. long by 3-3.6 mm. thick when fresh, 1.5-3.2 mm. thick when dry and then with longitudinal furrows, of equal diameter throughout or slightly tapering toward the base which ends in a small myceloid swelling; surface minutely and evenly lacerate scaly (the scales concolorous with the body of the stem and running horizontally around it and often with remnants of the gray, myceloid, outer peridium attached; context solid except for a small central strand of loose fibers; collar irregular, about 1 mm. distant from the dry stem, in contact with it when fresh, concolorous with the top of the stem. Spores very minute, 2-3/i thick, smooth, spherical or slightly angled with a minute mucro, spores cinnamon color (Ridgway) in mass, pale under the microscope. Capil- litium threads lighter colored than the spores, irregular, wavy, sparingly septate, 3.8;u thick, considerably swollen at the joints and at the ends which may be up to 12p thick _ In one of our plants there are four scarcely elevated mouths in a row and all elliptic to elongated, in another there are two circular mouths and in two others there is a single circular mouth. As T. Finkii (Lloyd; Myc. Notes, p. 1169, pi. 225, fig. 2307) agrees with our plant in its very characteristic spores, distinctly smaller than in any other species except in T. Longii, described by Lloyd as a form of T. albicans, which is white and has large rough spores, and as there are no essential disagreements we refer our plants to it. The multiple and somewhat elongated mouths in some of our specimens point to group 6 of Lloyd's Tylostomeae as its proper location. Lloyd's specimens having only single tubular mouths, he refers them to group 1. Tylostoma kansense and T. americanum (Lloyd thinks these the same) and the two new species proposed by Miss White (T. gracile and T. minutum) that if good might fall in the same group, are all easily sep- arated by their much larger spores. In T. Lloydii Bres. (in Petri, Ann. Myc. 2: 423. 1904) the spores are smooth and small but distinctly larger than in the present species, and the cortex is said to separate perfectly above, the mouth to be fibrillose until weather-worn. We have looked through the species represented in the Schweinitz and Curtis Herbaria, as well as in Washington and New York, and find nothing that agrees with our plant. #*"$ 00 w < Oh o TYLOSTOMATACEAE 155 Illustrations: Lloyd.

Mouth plane, not regularly circular, margin clean and smooth, single in all nine plants of our collection. There is no cortical cup at the base of the peridium. Collar short, fimbriate.

Capillitium threads very irregular, nearly hyaline, paler than the spores, up to 5n thick, with walls of varying thickness. This agrees very well with T. volvulatum as treated by Lloyd (Tylostomeae, p. 19, pi. 81) except for more slender aspect. The mouth is almost exactly like that of our Xo. 6060 (T. Finkii), as well as of the T. volvulatum-cespitosum-americanum group. Illustrations. Lloyd. As cited above. Sorokine. Revue Myc, 1890, pi. 98, figs. 347, 348; pi. 101, fig. 353a. Porto Rico.

We have examined what appears to be a true example of the species from Calloway, Nebraska (Bates, coll.; E. & E., Fungi Columbiani, No. 1889). The spores are quite smooth, irregularly subglobose, 4— 5/x thick, with the contents precipitated or fragmented into irregular particles which at first sight give somewhat the appearance of wrinkles on the surface. We find no actual wrinkles as figured by Miss White. Tylostoma obesum Cke. & Ell. is so close that we hardly see how the two can be separated. The spores of the Ellis plant at N. Y. Botanical Garden, mentioned by both Miss White and Lloyd, have been examined by us and found to be exactly like those of T. poculatum in size, shape, and surface, the contents differing somewhat in being less coagulated (pi. 119, fig. 12). Tylostoma granulosum of Europe is also very close. As represented by D. Saccardo (Mycotheca italica, No. 424) the spores are smooth and just like those of the American plants mentioned above, spherical to slightly irregular, 3.7— 1.4/j thick (pi. 119, fig. 13). Lloyd gives the spores of T. granulosum as granular and Hollos gives them as warted. Miss White's description of T. poculatum follows (Bull. Torr. Bot. Club 28: 431. 1901): "Peridium globose, somewhat depressed, 1-1.5 cm. high, 1-2 cm. in diameter, smooth, fawn-colored, membranaceous; outer peridium scaly, but more persistent than in most species, remaining in the shape of a cup-like involucre round the base of the peridium, mouth slightly raised, fimbriate, mostly large: collar entire, inconspicuous: 156 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA stem 1-3 cm. long, 3-6 mm. in diameter, cylindrical, firm, slightly bulbose, hollow or stuffed, often with considerable remnants of the outer peridium attached: capillitium lightish yellow, sparingly branched, septate, swollen at joints, 4-7/i wide, rather thick- walled: spores ferruginous, subglobose, smooth, or irregularly ridged in the older specimens, owing to the shrinking of the inner substance, short pediceled, 4-5/i in diameter."

This species, known only from Cincinnati, Ohio, is near T. poculatum, from which it seems to be distinguished only by its dark color and long stem. We have not seen it and give below the original description by Bresadola (in Petri, Ann. Myc. 2: 423. 1904; see also Lloyd, The Tylostomeae, p. 22) : "Outer peridium membranaceous, brown, soon falling away in pieces and leaving a concolorous zone at the base; inner peridium subglobose, papery, smooth, pale, sub- cinereous, flattened at the base and deeply umbilicate, about 1 cm. broad, 8-9 mm. high, mouth white, oblong, 2 x 1§ mm., slightly protruding, like a subfimbriate, tomen- tose circle, about 0.5 mm. broad, defined; stem hollow, fibrous-subwoody, brown, covered all over with rather thickly set, at length deciduous scales, apex tapering and sunken in the cup of the peridium and free from it on the sides, considerably thickened below and furnished with a pale, subvolviform, fimbriate membrane at the base, 6-7.5 cm. long, 2.5-3 mm. thick at top, 4-5 mm. at base, white within; gleba subochraceous; spores smooth, often inequilateral, 3.5-4 x 3.5/u; threads of the capillitium thick-walled, not easily separating into joints, hyaline, 3-9/i thick."

Plates 83 and 119 Spore case subglobose, about 1-1.8 cm. thick; outer peridium a sandy coat which wears away except for a basal disk exposing about two-thirds or three-fourths of the pale grayish to pale brownish, smooth or somewhat pitted, inner peridium. Mouth area a distinct, spongy, somewhat elevated disk which opens in the center by a circular or lacerate mouth to liberate the spores. Stalk 1.7-5.5 cm. long and 3^.5 mm. thick, usually longitudinally sulcate when dry, and shrinking away from the outer peridium so as to leave a distinct collar around its apex; surface layer dark brown, lacerate-scaly over most of the area, white within and with a central cottony cylinder as is usual in the genus; base expanding into a sandy bulb of moderate size. Spores (of No. 861 Ip) pale, spherical or slightly oval, minutely warted, 4.5-6.8/* or if elongated rarely up to 7.2^. Capillitium threads septate and slightly swollen at the joints, irregular and constricted at places with the lumen closed by the thickening of the walls, 3-6. 5/* thick. This species is a northern and western plant, and we have not seen specimens of it from east of the Mississippi. However, as it occurs on the shores of Lake Erie in Canada we include it as eastern American. As Lloyd says, this is the American representative of T. granulosum Lev. of Europe, of which T . fimbriatuni Fr. is a probable synonym. We have carefully examined the spores of two typical examples of T. PLATE 85 r1 * V S** iW Tylostoma simulans. No. 7504 [above] Tylostoma Imnkii. No. 6060 [below] Second plant from left moistened and swollen; others dry TYLOSTOMATACEAE 157 granulosum represented in D. Saccardo's Mycotheca italica, No. 424, and find them to be smaller and smoother than those of the American plant. In one plant (Path. & Myc. Herb.) the spores are spherical to slightly irregular, smooth or nearly so, 3.7 4.4/u thick; in the specimen at the New York Botanical Garden the spores are spherical to oval. 3.7-4.2p thick or if oval up to 5.5/i long. The southern representative of T. campestre has been named T. Berkeleyii by Lloyd, and while the differences are not great we are retaining the name (see that species for comparison). Lloyd is right in considering T. punctatitm Pk. only a form of T. cam- pesire. A part of the type collection at the New York Botanical Garden, noted below, is similar and with identical spores, minutely roughened, 5-6.5/1 thick. Illustrations: Morgan. Joum. Cin. Soc.

Capillitium sparingly septate, swollen at the joints, branched, irregular, 4-9/u thick, larger at the swollen joints. This is the southern representative of T. campestre. The spores of the present species differ only in having slightly more prominent warts which are distinctly more elongated so as to form a partial reticulum. The stem is less scaly (in plants seen); there is more color in the denuded inner peridium, and the size averages smaller. Illustrations: Lloyd. Myc.

Forh. 28: 171. 1871): "Peridium simple, membranous, smooth, fragile, furnished at the basal margin with a membranous collar and discrete from the stem, at length dehiscing irregularly. The apex of the stem extending into the peridium supports a rudimentary columella. Capillitium flocculent, scarce, attached to the peridium on all sides, continuous, con- torted, branched, hyaline. Spores very plentiful, in masses, short-pediceled, globose, verrucose-echinulate. Stem strong, fleshy-fibrous, loosely broken up externally in a peculiar way into fibrous shavings. Only one species known: Queletia mirabilis." The genus differs from Tylostoma in larger size and absence of a definite mouth or mouths, the inner peridium cracking and breaking up irregularly. There is no volva, but the structure and behavior of the outer peridium are not well known. In speaking of the capillitium as scarce, Fries seems to have been in error, as Miss White says it is abundant (see below). For references to Lloyd's observations see under the species. Queletia mirabilis Fr. Plate 119 We take the following description from Miss White, 1. c, p. 441: "Peridium globose, 2.5-3.5 cm. high, 3-4 cm. in diameter, fragile, easily separating from the stem, rupturing irregularly, of a reddish brown color; collar irregular, of the same substance as the peridium; stem 6.5-8 cm. long, 1.5 cm. wide at the top, 2 cm. at the base, fascicular, reddish brown, within and without, like the peridium, solid, lacerate, fibrillose, particularly at the base; capillitium very abundant and interwoven, forming with the spores a felt-like mass, reddish brown, single threads whitish yellow, thick- walled, hollow as shown by the truncated ends, septa rare or wanting, 5-9/x wide, branches rather short, free ends rounded and recurved; spores subglobose, coarsely warted, 4-6/x in diameter, some short-pediceled, inner portion breaking up and issuing from the thin-warted coating which is then hyaline and shrivelled." TYI.OSTOMATACEAE 159 A rare and interesting plant of curious distribution and habits. Lloyd in Myc Notes, p. 1S5, refers to the four places that the plant had been found up to that time. He later refers to another find in France (Myc. Notes, p. 337) and there gives structural details of young plants. There is only one American record, on tanbark at Trexlertown, Pennsylvania, where it was collected by Dr. Herbst, who found it three years in succession. We have examined the capillitium and spores of one of Dr. Herbst's plants from the Pennsylvania station (now in the New York Botanical Garden) and do not find the spores behaving in the way described by Miss White. They are strongly and ir- regularly warted, 6-9/i thick, often with a short pedicel. The capillitium is peculiar in fragmenting up at the joints into fairly long contorted sections with closed ends. They may of course be broken at other places to allow the entrance of air or water, but the completely closed sections are characteristic. For other references by Lloyd, see Myc.

SCLERODERMATACEAE Plants more or less globular, usually partly or wholly exposed above ground at maturity (but at times entirely embedded) ;* peridium thick or thin, tough or fragile at maturity, rupturing irregularly and tardily, or splitting at maturity into stellate lobes, or, in Pisolithus, flaking off in fragments from above downward; gleba divided irregularly by thin or thick sterile tramal plates into areas which from the first are stuffed full of the fertile tissue containing the irregularly arranged basidia. At maturity both plates and fertile tissue break down into a powder at times by slow degrees. Plants attached below by a thick mass of mycelial plates and fibers and sometimes stalked. Basidia swollen, pyriform to subspherical; spores spherical, echinulate and sometimes also reticulate, brown; capillitium none or rudimentary. A closely related family is Podaxaceae, a long-stalked group of large plants not represented in eastern United States. Podaxon and Phellorina occur in the western states. Key to the Genera Walls of the gleba chambers very thin and not forming distinctly outlined or complete chambers, dis- organizing throughout at maturity, together with the fertile tissue, to form a flocculent or powdery mass containing the spores Scleroderma Walls of the gleba chambers thick, forming distinct peridioles which slowly pulverize from above down- ward after maturity and exposure Pisolithus SCLERODERMA Pers. Characters of the family and distinguished from Pisolithus by the absence of distinct and persistent peridioles in the gleba. The plants are sessile except for a root- like attachment of plates and fibers mixed with earth. The brownish or purplish or olive-brown spores are echinulate or in several species obviously reticulated. In some cases there is visible regularly or at times (before much exposure) a peculiar veil or halo connecting the tips of the spines or reticulum. This effect is probably the result of a hyaline material which covers the spore between the spines. The spores of this genus show a remarkable peculiarity in their development. In 1889 it was shown by Beck (1. c.) that in Phlyctospora fusca Corda (Scleroderma Juscum (Corda) E. Fischer) the spores when somewhat more than half grown become surrounded by a sheath of cells which grow in from surrounding hyphae or much less often from the basidia. This sheath persists until the maturity of the spores and as the basidia have disappeared when the sheath is formed, the remaining growth and maturation of the spores is made possible by nourishment derived from the sheath. The sheath in most species is not so prominent as in S. Juscum, but in essentials the development of the spores is the same in all species investigated. We have studied S. lycoperdoides through these stages and find that the basidia disappear when the spores are only half grown and quite colorless. See details under that species. * Zeller has recently described a peculiar Scleroderma from Oregon that is normally quite subterranean and that is still more remarkable in having a deliquescent gleba. (Mycologia 14: 193. 1922.) Scleroderma pteridis is also subterranean (see p. 162). 160 PLATE 86 Scleroderma geaster. . No. 657 SCLERODERMATACEAE 161 The plants are firm or even hard until mature, and while probably not harmful so far as known are not of much value as food. Mcllvaine says (American Fungi, p. 615) that all the Sclerodermas are edible when young and never poisonous. Marshall says (Mushroom Book, p. 134) that S. aiiranlium (S. vitlgarc) has been eaten without harm, but is pronounced very unattractive. According to Bulliard it is claimed that S. vcrrucosum is deadly if eaten, but it is pronounced good by Mcllvaine (at least the plant he discusses as such). The spiny spores are distinctly irritating to the eyes. Literature Bambeke. Bull. Soc. Roy. Belgique 43: 104, figs. 1-4. 1906. Beck, t'ber die Sporenbildung der Gattung Plilyctospora Cda. Ber.

Key to the Species Plant large (4-10 cm. thick), the peridium thick and scaly and splitting at maturity into several more or less stellate and recurved lobes 5. geasler (p. 161) Plant smaller (2-5.5 cm. thick), the peridium thinner (from very thin up to 1 mm. when dry) and less stellate in dehiscence Peridium straw-colored before opening, smooth except for coarse cracks; spores not reticulated S. flavidum (p. 162) Peridium yellowish, nearly smooth or finely areolated; spores strongly reticulated 5. bovisla (p. 163) Peridium ochraceous or brownish, thick when fresh, thin when dry, the surface cracked into distinct, inherent scales about 1-3 mm. wide, which are with or without a stout central wart; spores strongly reticulated S. auraniium (p. 165) Peridium leather or bay color, thick when fresh, thin when dry, the surface only delicately cracked into areas and in large part smooth; spores not reticulated S. cepa (p. 167) Peridium light brown or yellow-brown, dotted over with minute, dark brown, inherent scales; thin when fresh and very thin when dry Spores spiny, not reticulated S. lycoperdoides (p. 168) Spores reticulated S. lycoperdoides var. reticulatum (p. 170) Scleroderma geaster Fr.

Plates 82, 86 and 120 Peridium about 4-13.5 cm. thick when closed and up to 15 cm. broad when open, subglobose, depressed and often irregular and lobed; sessile and entirely embedded until nearly mature, often remaining more than half buried; connected beneath with diffused plates and strands of floccose mycelium; peridium hard and rigid, up to 5 mm. thick when fresh, about 1-2 mm. thick when dry, nearly white, then yellow or dull yellowish clay or straw color, rough and more or less cracked into areolations and scales; splitting up irregularly at maturity into a varying number of lobes which curl back as they dry and expose the dark spore mass which is deep brown when fully mature. 162 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Spores deep brown with a slight tint of purple, globose, asperulate, not rarely with an imperfect reticulum, 5-10,u (most about 6.5-8yu) thick, including the spines which are up to about 0.5— 1/x long. This species gets its name from the way in which it cracks up, which is more or less stellate like the dehiscence of the outer peridium in the genus Geaster. It is a common plant in Chapel Hill, and is found from September through the winter in hard ground, preferring clay. The plants open in the fall and persist a long time, becoming black- ened and empty with age. They often appear on the clean, newly eroded pure clay sides of gullies, a most remarkable choice for a home. Scleroderma pteridis Shear (Bull. T. B. C. 29: 451. 1902) does not seem to differ essentially from S. geaster. The type was collected 2-A feet below the surface of the ground and attached to dead rhi- zomes of Pteris aquilina. The spores are given as 6-8/* and the peridium as 3-8 mm. thick, and the author states that the species differs from S. geaster in the thicker perid- ium and smaller spores. In our numerous collections of the latter the great majority of the spores come within these limits, and the peridium thickness is almost exactly 3-8 mm. in moist, unopened specimens. A plant from the type collection kindly sent us by Dr. Shear is unopened, as were all his plants, and most of the spores are im- mature. We find, however, a few that are like those of S. geaster, about 7.7-10/i thick, with surface spines. Dr. Shear writes (Nov. 27, 1923) that he is "now inclined to think that this may be merely a form or variety of 5. geaster." Illustrations: Boudier. Icon. Myc, pi. 186. Hard. Mushrooms, pi. 65.

Spores (of No, 675) spherical, 7.4-12.9/u, including the stout spines which reach a length of 1.5/i and not rarely show faint traces of a halo around their tips. They are mixed with numerous threads of the persistent trama which under the lens are nearly hyaline, branched, and 2.5-4.5^ thick. This is a good species and easily separated from 5. geaster, its nearest relative, by the smaller size, much smoother and thinner peridium and the larger spores with longer spines. Before opening the plants are partly or almost completely buried in the earth. The spore color of No. 675 is nearly the same as our S. bovista (sense of Bresadola), but the spores of the latter are entirely different, much larger and with a conspicuous and perfect reticulum. Smooth forms of the present species approach S. cepa in ap- pearance, but that can be separated from this by the thinner, more flexible, and gen- erally darker peridium. We have studied an authentic specimen of this species (E. & E., N. Amer. Fungi, No. 169S, 2nd ser.) and find the spores to be spherical or nearly so, spiny-warted, 8-12/x thick. 660.

Sense of Hollos Plates 89 and 120 Plants roughly spherical, usually flattened horizontally, at times lobed, about 1.5-4 cm. broad, narrowly or rather broadly attached to earth by a thick or slender root which diffuses at once into mycelial plates and fibers; surface when young smooth, dull, 164 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA remaining smooth or less often becoming cracked up toward maturity over part of the top into rather small, flattish areas about 1-3 mm. broad. Color buffy yellow to buffy when young, then leather color or sordid brown, the top tending to become blackish after maturity, and with black spots often present on paler plants. Peridium when fresh only 0.7-1 mm. thick, pure white in section and not changing when cut or rubbed, hardly more than 0.5 mm. thick when dry, at maturity splitting irregularly at the top; the spore mass soon becoming very dark blackish brown with a tint of chocolate. Tramal plates obviously yellow and until full maturity or after very distinct and perfect, the threads of the plates peculiar in that they swell and regain their form in water and can be distinctly seen to have clamp connections. Spores (of No. 725) about blackish brown of Ridgway, spherical, in most cases reticulated, but only imperfectly so in some, with a halo about the reticulum, 9-15.5m thick, including the reticulum which is up to 3yu high. There are in herbaria two plants passing for S. bovista, the one here described (our No. 725, etc.) and the following (our No. 5920). The first is in almost full agreement with Hollos's description and figures and we are considering it the species in his sense. Both plants are found in Bresadola's herbarium under the name S. bovista. The one here described is represented there by plants from Cincinnati, Ohio, sent by Lloyd, and illustrated by him as S. Texense (cited below). Lloyd's plant is the exact form as ours in every detail. The other form is represented by a European plant collected by Bresadola which is exactly like our No. 5920. It is larger than No. 725, has a longer and stouter rooting mass, a more yellow color, much thicker peridium, distinctly paler and larger spores, and tramal plate cells which do not regain their form when put in water. The English plant figured by Lloyd in Myc. Notes No. 8, fig. 43 is like our No. 5920 in appearance, and he says he has the same thing from Falmouth, Mass., growing in clear beach sand, exactly the kind of habitat of our No. 5920. Which of these two plants is the S. bovista of Fries we do not know, but think it likely that the species is truly represented by our No. 725 and Lloyd's plants from Cincinnati; and that our No. 5920 and the plant from Bresadola (and probably Lloyd's plant from Massachusetts) represent another species that has not been correctly understood. Petri's treatment of 5. bovista Fries apparently covers this plant. Illustrations: Hollos. 1. c, pi. 23, figs. 16-20. Lloyd. Lycoperdaceae of Australia, pi. 31, figs. 2-5. 1905.

Glebadark yellowish brown (sepia of Ridgw.); tramal plates yellow and quite persistent. Spores (of plant from Smith's Island) spherical, 11-18. 5m (including the reticulum), the majority between 12.5m and 14m thick, with a coarse reticulum, surrounded by a semi-transparent, pale yellow substance; treated with KOH solution the spore becomes lighter, the reticulum clearer, and the gelatinous material swells considerably. The distinguishing characters of the plant are its smooth to minutely areolated yellow surface, thick peridium (even when dry) which is white in section, long thick root, olive-brown spore mass mixed with yellow trama, and the large and coarsely re- ticulated spores. For a comparison with S. bovista, sense of Hollos, see that species. The species can readily be distinguished from 5. lycoperdoides by the larger size, more yellow color, paler and far less conspicuous areolations, and by the strongly reticulated spores. Scleroderma cepa, which is about the same size and color, differs (when dry) in the thinner and less brittle peridium, more reddish spore mass and non-reticulated spores; S.flavidum differs in the much paler straw color, coarsely cracked surface, and non-reticulated spores; 5. aurantium has a much rougher surface, and when dry a thinner and less brittle peridium. We have compared our plant with a good example in Bresadola's herbarium col- lected by him in Europe, and find them just alike in appearance and spores, which are in the latter 9.3-14m thick, not counting the reticulum which is up to 3fi high.

Gleba gray then nearly black, the tramal plates white. Spores (of No. 5622) blackish brown, strongly reticulated, 8-1 1m thick, not counting the reticulum w^hich is 1.5-2m high. This is recognized by its verrucose and usually distinctly warted surface, thickish peridium which turns pink when cut in the fresh state, white tramal plates and re- ticulated spores. It is nothern in its range and in the south we have found it only in the mountains. It grows in either deciduous or coniferous woods, but seems to prefer mossy humus or very rotten wood under hemlock, spruce or pine. This is the species that is occasionally parasitized by a Boletus (B. parasiticus) and we have found a fine example of this condition at Blowing Rock (see Journ. E. M. Sci. Soc. 42: pi. 48. 1927). 166 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA A plant from Bresadola's herbarium determined by him as 5. vulgare is the same as 5. aurantium, with spores 7-11.8/i thick. Maire's cytological work on this species we quote below (Comp. Rend. 131 (2): 1247. 1900). It will be noted that he states the spore number to be four. Tulasne says they are "usually four, sometimes two, three or five," and he also states that their respective positions are very variable. "The study of the basidium is especially interesting in Scleroderma vulgare. At the beginning of the prophase of the first division, the cytoplasm contains a certain number of granules which stain black in iron haematoxylin, around which radiate the micro- somes. It seems clear that two of these granules become the centrosomes, for a little later only two from among them show as center of radiation; they are then placed on each side of the nucleus whose nucleolus and membrane soon disappear, while the chromatic reticulum is transformed into two irregular knotty clubs which represent two chromosomes and which extend almost from one centrosome to another. "At the same time there is organized between the centrosomes a spindle; the two chromosomes contract while increasing in thickness, then divide into two longitudinally, while shaping themselves into a "V" until they are end to end parallel to the axis of the spindle. They are then directed toward the poles and there reunite into a chromatic mass which covers the centrosomes and from which seem still to radiate the astral rays. The spindle soon disappears and the second division begins almost immediately : there is formed around each nucleus a spindle with centrosomes and asters. All the granules of the cytoplasm are massed on the radiations of the asters, except some which remain in a parietal layer at the base of the basidium, in such a way that, except for this residue, everything that is visible in the cytoplasm is oriented with regard to the four centro- somes. The second division is like the first, since the events take place as if the four centrosomes determined the formation of the four spores; they disappear moreover on the arrival of the nuclei at the latter, to reappear only at the mitosis, which takes place in the spore some time after its formation." Maire also makes the general statement in regard to this species, as well as all others studied [Geaster kygrometrkus, Lycoperdon caelatum, excipuliforme, gemmatum; Nidularia globosa, Cyathus hirsutus] : "We have observed the fusion of only two nuclei in the young basidia. The subhymenial cells always contain two associated nuclei with conjugate mitoses. Many cells of the other tissues when they are old contain a more or less large number of nuclei, but these nuclei come from an amitotic fragmenta- tion of the two primitive nuclei. The number of chromosomes is two in all species studied." Illustrations: Bambeke. I. c, fig. 2. Boudier. Icon. Myc, pi. 145. This shows the condition parasitized by Boletus parasiticus. Bulliard.

Smooth forms of this plant resemble S. bovista (in sense of Hollos) in surface ap- pearance, but can be distinguished from the latter by the less rigid and less brittle peridium, less dark spore-mass (if mature) and the smaller, spiny spores which are without a reticulum. Young plants are separated by the paler color and purplish color change of the peridium. Rough forms approach 5. flavidum in appearance, but that is easily separated by the thicker, more brittle and paler peridium. Illustrations: Bambeke. 1. c, fig. 4 (spores). Fries, Th. C. E.

(Univ. Wis. Herb., as 5. verrucosum, and U. N. C. Herb.) Spores warted, 7-10/t. Scleroderma lycoperdoides Schw. Plates 94 and 120 Gregarious or cespitose; body 0.8-5 cm. (most about 1.5-2.5 cm.) broad, usually- broader than thick; surface light brown or yellowish brown and dotted all over with minute darker brown or reddish brown, separated, inherent scales; becoming blackish on long exposure; smooth or minutely roughened; flat below and abruptly rooted by a stout embedded stalk of varying length which is soon dissipated into a few strong, stout strands and plates or into many smaller fibers. Peridium thin, when fresh and immature 0.5-0.7 mm. thick, becoming thinner and on the inside obscurely defined, the inner layer becoming fibrous like the trama and continuous with it and wearing away so as to leave in age only a very thin outer layer of a more leathery texture. Glebal chambers very small, about 0.2-0.5 mm., the plates very thin and composed of delicate rather straight hyphae about 2.5-3.5/u thick. Spore mass when very young watery cream color, then deep brown and faintly purplish, changing to paler grayish brown with or without a faint tint of olive after maturity; the delicate threads and plates of the trama are not quickly disintegrated but remain as a decided matrix for the exposed spores as they are slowly dissipated. There is no distinct dehiscence, but after much delay there appears an irregular worn opening in the tip and there are often other pores made by grubs. In age the stalk and all the basal part of the body are left as an empty saucer. Spores deep brown, spherical, asperulate, not reticulated, very variable in size of body and length of spines in the same plant: in No. 5201 they are 7. 5-18. 5^ (most about 11-14/i) thick excluding the spines which vary from a length of 2\x (rarely) to scarcely more than pointed warts (all from one fully mature plant). In No. 3488 a halo was noticed connecting the spine tips over a part of the spore surface in many cases. Basidia (of No. 5253) 7-8.5ju thick with 4-8 sessile spores. While still half grown and before the gleba has a tint of brown the spores are formed and the fertile tissue stuffing the chambers, including the basidia, has undergone a disintegration into a translucent almost structureless mass surrounding and embedding the spores, which at this time are hyaline, smooth and only about half the size they attain later. It seems certain that the spores are nourished by the surrounding matrix and undergo growth and maturation after separation from the basidia, as in 5. fuscum (see under the genus). This is our commonest Scleroderma in Chapel Hill. It prefers damp, shaded places on bare ground or in thin grass or moss, but is often found on rotten logs in swamps. It appears every year in the same places. The correct name has been in much doubt. In American herbaria and literature it appears as S. verrucosum (Bull.) Pers., or S. tenerum B. & C. (Cuban Fungi, No. 512). It is certainly near S. verrucosum, as that species is now understood in Europe, and larger individuals pass for that species in America. In fact one meets rarely with small European specimens which cannot be distinguished from the typical American form. Such a plant is represented in Rathay's Flora Exs. Austro-Hungarica, No. 1559 (U. S. National Herbarium). We have always felt with Lloyd that the European name could hardly be applied to the present small species. A European plant from Bresadola's herbarium (as S. verrucosum) has spores PLATE 93 *SSk> Scleroderma cepa. No. 7515 [above] ; No. 7547 [below] SCLERODERMATACEAE 169 that can be matched by our plants, asperulate, 6.6-18/i, most about ll-14/i (pi. 120, fig. 12), but the surface, while cracked into areas, is not dotted with small separated scales of a different color. Lloyd uses S. tcnerum for our U. S. American plant, and the Cuban plant certainly represents ours in the tropics. The types at Kew (kindly loaned us by the director) consist of two good plants. One has the surface of our plants; the other has more pronounced warts (pi. 95). The spores of both are the same and are like the American form except for the average smaller size, 8-11/x, most about 8.5-10/x (pi. 120, fig. S). They are almost exactly the size of the spores of S. cepa. We have fortunately been able to find a good name for our form of the plant as proved by an authentic specimen of 5. lycoperdoides in Michener's herbarium from the Schweinitz Herbarium. The specimen is in good condition and shows all the characters of our plants, the spores 10-15/i thick, covered with short or long, sharp spines which become clear only after a treatment of K.OH has dissolved away the gelatinous, granular material between them. Lloyd did not find the species represented in the Schweinitz Herbarium in Philadelphia and so hesitated to use the name. There is, however, a fragment of this in the Schweinitz Herbarium which has the same spores as the plant above mentioned (10.5— 13ju)- There are also fragments from the Schweinitz Herbarium in the Curtis Herbarium labelled S. lycoperdoides which seem to be the same. The spore structure of S\ lycoperdoides is as in 5. cepa (No. 3109) except that the spores in the present species are considerably larger and more variable.

Distinguished from Scleroderma by the distinct peridioles or irregular bodies that with their separating walls make up the body of the gleba and contain the spores. A number of species have been described, but all those of the northern temperate zone are probably only forms of the one that occurs here. There is certainly nothing in the descriptions to separate them. Differences in form, as presence or absence of a con- spicuous, simple or complicated stalk, and surface color of peridium are all certainly worthless. The plant is a common one in Chapel Hill and all forms occur. The fresh young plants if unweathered are very obviously yellow, but this soon changes to shades of brown or blackish on exposure. This has been widely treated as Polysaccum, a genus now known to be antedated by Pisolithus. Literature Bambeke. Bull. Soc. Roy. Bot. Belgique 42: 178. 1906. Massee. Revision of Polysaccum.

Peridioles in section whitish or yellow, then watery vinaceous, then through darker vinaceous to nearly black, subspherical, irregularly angular, usually compressed, about 1-2 mm. thick and up to 4 mm. long, smaller toward the base; texture that of a firm elastic and translucent jelly until the desiccation of maturity. Peridioles separated by a nearly black jelly enclosing a densely woven mass of delicate threads with clamp connections. Spore powder cinnamon brown; spores globose, spiny but with the spines covered with a gelatinous material that makes them look blunt when first put into water, 7— 11.5m thick, counting the spines which are up to ly. long. This peculiar plant is common in fall in well drained gravelly and sandy soil, as pastures, old fields, thin places in lawns, etc. The dry spore powder is scattered by the breaking down of the peridioles after the peridium cracks off. This disorganization proceeds by degrees and the lower peridioles are intact for some time while the upper part is being dissipated. The old, woody, discolored base remains intact for months. The blackish jelly between the peridioles and the peridium also of this plant gets its color from a bright olivaceous yellow pigment which quickly stains cloth or paper and is hard to remove. It is said to be used for dye for cloth in France (Lloyd, Lyco- perdaceae of Aus., p. 12). When put under the microscope this jelly itself is seen to contain most of the pigment, the threads being pale. The vinaceous purple color of the jelly in the peridioles is due to the maturing spores, the threads and jelly around them being colorless. If a ripening peridiole be put into water the purplish pigment in the spores will diffuse into the water and color it. The plant thus contains two distinct pigments, a yellow and a purple one. The purple tint of the spores is lost at full maturity, the dry spore powder being deep brown without purple. The very surface of the peridioles is covered with a thin weft of yellow fibers that are not gelatinized and contrast strongly with the jell}' on each side. When fresh the very thin weft of fibers that make up the peridium is lined beneath by about one millimeter of the same black jelly that surrounds the peridioles. This is mottled with yellow plates as if the outer peridioles had been aborted. The spores of P. crassipes as illustrated by Tulasne show thick, rounded warts rather than spines, but we do not take this to be evidence that the plants are different. When first put into water many of the spores have thick, rounded warts but these become sharper after standing awhile or on appb'cation of KOH. As in the case of Scleroderma and the Nidulariaceae, it is obvious that the spores grow considerably after the basidia disappear by gelatinization. At the stage shown in fig. 17 the basidia have lost all their contents and are almost invisible, yet the spores are only about two-thirds grown. Figure 18 shows the mature spores at the same magnification. As Persoon's Synopsis Fungorum is now generally accepted as the starting point for the nomenclature of the Gasteromycetes, there is no reason why his specific name (based on Micheli's plate) should not be applied to this plant. Though Lloyd suggests this, we cannot find that the combination we use has ever been published before.

No. 5402 NIDULARIACEAE Plants small, growing on the ground, on dead vegetable matter or on dung; cup- shaped or goblet-shaped or globular; the mouth in two genera closed until maturity by a membrane (the epiphram); gleba in the form of separate, lens-shaped bodies (the periodioles) of easily visible size, which contain a number of large, smooth spores and are covered by a dark, hard, protective coat which is with or without an obvious superficial, white, thinner layer (the tunic). Basidia clavate, with 2-8 smooth, sessile or stipitate, apical or scattered spores, forming in Crucibulum a definite hymenial layer near the center, but in Cyathus occupying irregularly, together with sterile threads, a large central area of the peridiole. Spores smooth, usually flattened, binucleate in the species studied. Capillitium lacking. The peridioles do not open of their own accord, but liberate the spores only when eaten by insects (or when decayed?). The tunic is thick and removable in Crucibulum, very thin and obscure in Cyathus (Lloyd thinks it entirely absent in C. stercoreus). The hard wall of the peridioles is only superficially black or brown, and composed almost entirely of very irregular, branching and knobbed, very thick-walled sclerotic cells, which, when a peridium is crushed, are found scattered abundantly among the spores. In nature they retain their position and are not mixed with the spores. These cells are only remotely, if at all, homologous to the capillitium of other genera. Next within this hard layer comes the spore-bearing tissue which may or may not form a definite hymenial layer. See under the different genera for details on this point. The spores have been made to germinate in water and in culture media and have produced fruit bodies in pure culture (Walker, Hesse, Eidam) . On account of the peculiar resemblance to little nests with eggs, these plants are popularly known as "bird's-nest fungi." So far three of the four genera have been found in the eastern states. In two of these the peridioles are connected on their under side to the wall of the peridium by a cord (the funiculus), which is elastic when wet and brittle when dry. In Crucibulum it is usually very obscure after maturity and often disappears from gelatinization. In Cyathus, the funiculus, while much more conspicuous, may be rarely entirely lacking from some of the upper peridioles (Miss White, Lloyd). In the other they are free from the wall, but embedded in a mucus. The spores are hyaline, and are elliptic or subglobose. They vary a great deal in size from the comparatively small ones of Crucibulum vitlgare to the immense ones of Cyathus melanospermus. They also vary considerably in the same collection and at times in the same peridiole, and they are much more abundant in the small-spored species than in those having large spores. In 1902 Miss White (1. c.) brought together in convenient form the species known from North America and established a new genus, NMula, with two species from the western states and Canada. Lloyd (1. c.) adds a third species (the Cyathus emodensis of Berkeley, Kew Journ. Bot. , p. 204. 1854) and extends the geographical range of the genus. For the structure of the peridioles, see Tulasne, Walker, Lloyd, or Fischer, as cited below. Fischer sug- gests that the family may have descended from the Hymenogastraceae, mentioning Octaviania, but the origin of this group is certainly very obscure. Lohwag (cited on 173 174 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA p. 194) expresses the surprising opinion that these plants are related to Tylostoma and represent a compound group of Tylostoma fruit bodies enclosed in a common sheath.

Key to the Genera Peridioles (or most of them) attached by cords to the cups Peridium cup-shaped with a thick wall composed of a single layer; peridioles whitish from the thick white tunica Crucibuhim (p. 181) Peridium bell-shaped or goblet-shaped, with walls of three obvious layers; peridioles gray or nearly black; tunica thin or wanting Cyathus (p. 174) Peridioles not attached by cords, but embedded when fresh in a mucus Peridium thin, spherical, falling into fragments Nidularia (p. 183) Peridium thick, cup-shaped, opening at the top Nidula CYATHUS Haller Plants distinctly bell-shaped or goblet-shaped; the tough peridium composed of three distinct layers, in expanding towards maturity exposing a thin, pale, usually almost smooth epiphram which is stretched across the top and which disappears with age. Peridioles attached by a cord, black or dark brown, in some cases covered with a very thin tunica, which, however, does not completely hide their dark color. Basidia not forming a distinct or homogeneous hymenium, but scattered at irregular heights throughout a large central area and intermingled with numerous delicate threads which at maturity have their cell walls greatly thickened and gelatinized to form a solid horny matrix, throughout which the spores are unevenly scattered. At the time the spores are growing, this matrix is not horny but gelatinous, becoming horny at maturity. MDULARIACKAF. 175 Under ordinary powers of the microscope the almost closed lumens of these thick-walled threads have the appearance of delicate filaments running among the spores. Minute, amorphous granules are also found in abundance. The hyaline, sclerotic layer, com- posing the greater part of the wall, is composed of crumpled and distorted cell units with very thick walls. In Cyutlius these units do not separate when crushed but break up into irregular masses and bits of cells; in Crucibulum they separate in great part when crushed and the individual cells can be easily seen and drawn. For other differences in structure see under Crucibulum vulgare. The spores of this genus show the remarkable peculiarity of carrying on a large part of their growth after the basidia that produced them have entirely disappeared. When the spores are about half grown or less, the basidia become empty and gelatinize, leaving the spores embedded in the gelatinous matrix mentioned above. As shown in several figures on plates 122 and 123, the threads producing the matrix can be seen to wrap about the spores in large numbers. It is obvious that these threads furnish the nutrition necessary for the post-basidial growth of the spores. This remarkable con- dition is found also to a somewhat less degree in Pisolithus and Scleroderma, which see. At the Washington meeting of the Botanical Society of America (Dec. 1926). Prof. George W. Martin gave a paper on the basidia of the Nidulariaceae in which he brought out this fact. Our work on the subject had been completed two years earlier. In addition to the species listed below, Miss White includes from our territory C. intermedins, referring to it a plant from Delaware. Other collections of this species are from the tropics, and from Miss White's description the Delaware plants could readily be referred to C. striates. For C. rufipes see discussion under C. stercoreus.

Peridioles confined to lower half of the cup, 1.5-2 mm. in diameter, usually attached to the cup by a strong, very elastic cord. Tunica very thin (ll-30/i), often absent in places, but usually obvious, so that the peridioles appear gray or silvery brown; composed of light brown, collapsed threads; black layer thin (about 20/*), dense; sclerotic layer 110-365/j thick, its cells vaguely outlined and not separable as units on crushing. Spores (of No. 2432) scattered as usual in the central horny tissue, elliptic, hyaline, rather thick-walled, 8.3-12 x 15-22/1. When young the wall is very thick, becoming thinner as the spores mature. Basidia long-clavate, 6.8-7.8/* thick, with 4 sessile spores. Not rare on dead wood and other vegetable matter. The young plants have rounded hairy tips, the peridium expanding above and the hairs seceding so as to expose the thin diaphragm only a little while before full maturity.

Peridioles 1.6-2 mm. wide, flat, black, dull or a little shining, the funiculi conspicuous. Spores short-elliptic, 11-20.3 x 22-4%. This species is easily distinguished from others of its group by its large spores and striated outer as well as inner surface. It is new to the United States, being known heretofore only from northern South America and the West Indies. There is at the New York Botanical Garden a collection of this marked "in bamboo pots" (Stevenson, coll.) with no other locality data given, but probably from the tropics.

Plates 100 and 121 Plants goblet-shaped, about 5-10 mm. high in our collections, almost sessile or with a short stalk, gregarious in large numbers and usually crowded so that a group of old plants looks very much like a wasp's nest; growing usually on manure or on earth where manure has been spread. The mycelium is rufous as in all other species we have seen except in C. Lesueurii, and it sometimes forms an obvious pad at the base of the cup. Outer surface tawny when young, then tan to buff or gray-brown, covered with thick, matted, woolly hairs, which with age become worn off, leaving the cups almost smooth; inner surface smooth, even (not striate), dark grayish brown to nearly black in age. On expanding above from the rounded, strigose stage of youth, the delicate epiphragm is exposed, only to break and disappear in a short time; mouth smooth, not fimbriate (the surface hairs that project above it soon after opening do not constitute a fimbriate mouth). Peridioles nearly black, without a tunica, 1.5-2.5 mm. in diameter, with a thick, hard wall, usually attached to the cup by funiculi, although often we find some of the upper peridioles in the cups which show no signs of a funiculus and wrhich drop out of the cup when it is inverted (as noticed by Lloyd). Outer removable layer (tunica?) and denser layer below about 90-130^ thick; sclerotic layer about 37/* thick around the edge of the peridiole, about 165yu thick on the sides near the center. Spores (of No. 39) almost hyaline, subglobose to oval, thick-walled, varying greatly in size, 18-30 x 22-35/j. Basidia (of No. 5916) club-shaped, distinctly swollen at the distal end, 9-12.5 x 28^4ju, bearing 4-8 sessile spores, only 2 or 3 of which mature. The spores may be attached to any part of the basidium, but are usually borne in a circle near the end. After the spores are formed the basidia collapse, finally leaving long threads among the spores, the layer just beneath the hymenium becoming sclerotic. Not rare and often in large colonies on manured ground, dry manure, and much more rarely on decidedly rotten wood. In the large spores, the species approaches 178 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA C. melanospermus, but that has distinctly larger spores on the average, and a fimbriate mouth. Miss Andrews (1. c.) says that the spores of the type of Nidularia stercorea in Schweinitz's herbarium are 15.8— 18.7ju, and thinks it perhaps the same as C. Z,e- sueurii var. minor Tul. We find the spores of the type to be 16.5-22 x 18.5-27^. Illustrations: Andrews. 1. c, pi. 17, figs. 2 and 6 (as C. stercoretts) ; figs. 1,3,5, and 7 (as C. Lesueurti). Hard. Mushrooms, fig. 443.

Peridioles 1.6-2 mm. wide, smooth, black, shining, not concave below, the funiculi represented only by a little central plug at the time found. Spores (of No. 7458) smooth, oval, thick- walled, 11.4-14.8 x 15-18. 5/*, borne as usual in the genus. While the spores of our plants run larger than in the type, as given by Miss White, other characters seem to fit well except for the darker outer surface of the former. The species is near C. stercoreus, and Lloyd thinks they are the same. In all of our collections of C. stercorals the spores, though variable, run much larger than in the present species. Lloyd finds the spores of Japanese specimens to run as low as 16-24/x, while for American plants he gives the spores as 30-40/i. On account of the different PLATE 99 Crucibulum vulcare. No. 7462.

Plate 123 Plants very slender, about 6-8 mm. high and 3.5 mm. broad at the top, brownish drab below, dull gray above; upper part fibrous to strigose, lower part felted; mouth surrounded by long, scattered hairs. Inner surface smooth, blackish brown. Base without a pad, but the concolorous mycelium holding a ball of earth. Peridioles about 1.7 mm. broad, very thin, nearly black. Spores (of No. 7281) subspherical, very large, 18-29 x 20-31^- Gregarious to crowded in fine, sandy soil. This seems to agree prefectly with C. Lesueurii except that the plants are not quite so large and grow on poor soil without obvious humus. The shape, however, is more that of the typical form than of the variety minor. Both Miss White and Lloyd, as well as Hollos, consider C. Lesueurii var. minor as a synonym of C. stercorals, and in this seem certainly correct. The first two authors also consider C. Lesueurii as indistinguishable from C. stercoreus, and they are probably right in this also in so far that intermediates occur. As the present plants grew on sand, are more slender than in C. stercoreus, and have a peculiar appearance, we think it well to retain the name for the present. Tulasne gives the spores of the variety, which he describes from "Carolina," as 17.5-19.8 x 22.3M. Illustrations: Tulasne. 1. c, pi. 5, figs. 5-10. Florida.

De Toni Plates 100 and 122 Cups gregarious or crowded, distinctly infundibuliform, or sometimes somewhat long-campanulate, 9-12 mm. high by 6-8 mm. broad at the mouth, which is slightly flaring; outer surface shaggy-hairy, the hairs collapsing and largely disappearing on long exposure; color in our plants which are old, dark brown, about Mars brown of Ridgway, in some with a slight tint of purple; inner surface even, smooth, and about the same color as the outside. Mouth straight and distinctly fimbriate. Peridioles 1.8-2.3 mm. in diameter, almost black, with a rather thick outer layer of coarse, dark brown fibrils with dark granules between. When wet this coat is easily torn off with a needle, and underneath is a thin, dark, hard layer of densely packed threads and granules. Inside this is the much thicker layer of pale sclerotic cells and within this is the hy- menium which is recognizable only in the young condition. The rather ample "cavity" in the center is filled with the immense spores lying in a horny (when dry), hyaline matrix formed of greatly gelatinized threads. Funiculus large, strong, and very elastic. 180 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA Spores hyaline, round to short-oval, very large and varying greatly in size, 24-35 x 28-48^, some with very thick walls, 3-4/1 thick. The extremely large average size of the spores of this species is supposed to dis- tinguish it from others of its group, and in our collection as well as in the type they do run larger than in C. stercoreus. The average length of ten spores of our No. 23 measured as one came to them was 34^, while ten of C. stercoreus measured in the same way was 24.9m- The types in the Schweinitz Herbarium are a good lot of 16 plants densely set together, shape and appearance about as in C. stercoreus. The only egg well seen was smooth and black; spores subspherical to oval, 20-31 x 26-38^, which is very little larger than in C. stercoreus. Miss White gives the spores of the type as 45-55 x 18-45/*. Lloyd considers the species as a synonym of C. stercoreus and says he "can find no differ- ence in the general size of the spores from the type material of C. stercoreus and C. melanospermus. While in the latter there are many large spores, there are also small ones and some we note measure not over 20 mic." The distinctly fimbriate mouth in our No. 23 is probably of no specific importance, and in the type the mouth is smooth or slightly fimbriate. While we retain the species at present, Lloyd is probably right in regarding it as a form of C. stercoreus. Illustrations: White. Bull. Ton. Bot. Club 29: pi. IS, figs. 1-4. 1902. 23.

Plants cup-shaped or bell-shaped, sessile, gregarious on twigs and trash in general or on the bark of logs, or rarely on living trees. Wall composed of a single thick layer which in youth is velvety-tomentose externally, becoming almost smooth with age. Inside of the cup covered with a thin, pale lining and without striations; the mouth in youth covered with a thick, soft veil or epiphragm which disappears with maturity. Peridioles numerous, almost filling the cup and attached to it by simple funiculi. Tunica thick, white and quite conspicuous. The basidia forming a distinct and closely packed hymenium surrounding a narrow central area which at maturity becomes densely filled with spores. All the cells of the hymenium then become very thick-walled and fuse together into a solid, hyaline, subhorny tissue, which seems almost structure- less under low power. The spores are not embedded in cellular tissue, but stick together by their surfaces and do not fall out when exposed. This organization of the fertile part of the peridiole is quite different from that in Cyathus, which see. There is but one species in the genus. Crucibulum vulgare Tul. C. criicibuliforme (Scop.) White Nidularia Juglandicola Schw. Plates 61, 99, 101 and 122 Plants bell-shaped or cup-shaped, sessile, varying greatly in size, even in the same collection, from 3-7 mm. high by 4-8 mm. broad at top, but not so crowded as Cyathm stercorals, growing on trash or twigs of various kinds, bark of decaying logs, or even on the bark of living trees; when young covered with an ochraceous tawny, velvety tomentum (much less coarse and shaggy than in Cyathus stercorals), then becoming almost smooth, brownish, light tan or grayish with age. Inside of the cup smooth and sometimes shiny, and usually silvery gray to white. The epiphragm, which closes the cup until maturity, consists of two layers, the outer one felted-tomentose, colored like the cup, and made up of short, thick hairs with many short, stubby branches; the inner layer white and made up of an interwoven mass of slender, much branched filaments. In withering, the outer felted layer of the epiphragm sloughs off first, leaving the very thin layer which soon also tears and withers away. The peridioles are lenticular in shape, 1-2 mm. in diameter, attached to the cup by cords and covered 182 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA with a rather thick white tunica which frequently ruptures. Under the tunica is the thin black layer composed of slender filamentous dark brown cells mixed with a large amount of granular, amorphous material. Beneath this is a thicker layer (95-1 15m) composed of hyaline, thick-walled, sclerotic cells, hard and horny when dry but much softer when soaked for several hours. Nest comes the hymenium which is peculiar in that the old basidia and intermediate cells also become thick and sclerotic after spore formation (see fig. by Sachs, 1. c, and our fig. 8). The funiculus is composed of a delicate fascicle of long, thick-walled, hyaline threads which are rarely branched, and which have at intervals peculiar joints. At maturity many of the funiculi may have disappeared, and the peridioles be held in only by a small amount of mucus. Spores (of No. 647) hyaline, elliptic or oval-elhptic, and varying greatly in size, 3.5-5.5 x 4.3-8.6/i. Basidia (of No. 5277) long-clavate, about 3.7yu thick at the swollen tip, with 2-4 spores on distinct, slender sterigmata. A very common and widely distributed plant, growing on wood, twigs and other vegetable matter. Referring to Lloyd's remark that it rarely if ever occurs on large logs, we have several collections from the bark of logs and living trees (Nos. 35, 1534, 2904, 2986 and 2987a). One collection (No. 2904) is on sound bark from a large hickory log. The cups of this collection are a little larger than the average, but agree in other respects.

Peridioles small, flattened, only up to 0.8 mm. wide, dark brown, wrinkled when dry, densely packed, destitute of a funiculus or other attachment to the wall, but embedded in a mucus when fresh and damp and lightly stuck together by this mucus when dry. The surface of the plants may be nodulated from the pressure of the peridioles within. After maturity the peridium ruptures irregularly and does not form a perfect cup as in the other genera.

It was first described under this species name from North Carolina, but Lloyd is probably right in thinking it the same as N. pisiformis of Europe, which has also been described under many other names. We have examined the type of Nidularia alabamensis and find that it agrees in all respects with N. pulvinata.

We take the following from Miss White (1. c, p. 276) : "Peridia small, elongate-globose, or subspherical, sessile, sometimes confluent, 0.5-2 mm. long, 0.5-1 mm. high; peridial walls very thin, and brittle at first, pale yellowish fawn-colored, gradually as the plant matures becoming grayish, and some- what tuberculose from the inner pressure of the sporangioles, dehiscing irregularly, the outer covering often breaking away completely, leaving the sporangioles seated alone on the wood, barely visible without magnification; sporangioles yellowish brown, very numerous, crowded, circular, flattened above and below, barely 0.25 mm. in di- ameter, even or slightly creased under high magnification; spores subglobose, hyaline, thick-walled, 4-7yu long, 3-6/i wide.

CALOSTOMATACEAE Fruit body hypogean or partly so until maturity, attached by obvious basal strands; with or without a stalk. Peridium highly specialized and formed of several layers. Gleba without cavities or organized hymenium, separated into small blocks by delicate tramal plates or strands. Capillitium or its rudiments arising from the whole inner surface of the inner peridium. Basidia irregularly arranged, stout, club-shaped, bearing several, usually more than 4, spores irregularly scattered and sessile around its surface. Spore powder dry and escaping by an apical mouth. ASTRAEUS Morgan This genus, formerly included in Geaster and of the same general appearance, was established by Morgan on the following essential differences: no open chambers and therefore no organized hymenium ; threads of the capillitium long, much branched and interwoven, scarcely different from the elemental hyphae of the peridium and con- tinuous with them, in these respects agreeing with Tylostomd; columella entirely lacking ; spores much larger than in any Geaster. The hygroscopic character of the rays is very marked, as is their hard and woody texture when dry. There is but one species known. Morgan and Burnap call attention to the apparent relationship of this genus to Tylostoma and Colostoma and Fischer puts it in the Calostomataceae, in which he has been followed by others. We are following this precedent, although it is far from clear that it belongs here rather than in the Tylostomataceae. It seems to us that it would be better to establish another family for it, as its presence in any recognized one makes the definition of that family awkward and unsatisfactory. Fischer's definition of the Calostomataceae includes the statement that the capillitium is well developed. This is not true of Colostoma, in which the rudimentary "capillitium" disappears entirely before maturity (see p. 189). Relationship to Colostoma is shown mainly in the organiza- tion of the gleba into stuffed areas and the stout basidia with a varying number of scattered, partly lateral spores, and the highly complex organization of the coats. Its relationship to Tylostoma is indicated by the absence of open chambers, the basidia and spore characters, though the latter has only 4 spores, and by the highly developed capillitium, which arises from the entire inner surface of the peridium.

Plates 31, 77, 115 and 117 Plants of small to medium size, growing in colonies just beneath the soil or partially exposed, arising from a group of black, hairlike, basal rhizomorphs. Outer peridium 185 186 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA thick and composed of several distinct layers (see below) ; surface hard, smooth (except when very fresh or very old), at maturity splitting into six to many rays which expand or recurve when wet and fold in again when dry, the inner layer soon becoming much cracked. Inner peridium pliable, thin, sessile, depressed-globose, about 1.2-3 cm. broad, surface felted and when in good condition reticulate with fibrous lines, whitish, becoming gray or brownish, opening by an irregularly torn mouth which is without a defined peristome. In the fresh condition the plant is tasteless and odorless. Gleba pure white in youth, divided up into very small, more or less box-like regions by very thin tramal plates, each chamber closely packed with the fertile, practically homogene- ous tissue; this mass being made up of branching threads and small fibers bearing more or less grape-like clusters of nearly spherical basidia, which are crowded amongst each other, leaving only small unoccupied spaces here and there. Spores 4-8 to a basidium, sessile on its top and sides, reddish brown, globose, distinctly tuberculate, 7 .4-10.8/1 thick including the warts. Basidia irregularly ar- ranged in long strings of clusters, subspherical with a stalk, 11-15.5 x 18-24/x. Capil- litium threads arising from the entire inner surface of the peridium, including the base, very pale, long, interwoven, branched, 3-5.5/j thick, smooth or encrusted with granules and without any obvious tapering terminals; walls very thick, so as to leave no lumen in many places; no cross walls obvious. The plant is very persistent. Ripening in the fall, it may be found in good condi- tion through the winter and spring and the shape is retained for more than a year of exposure. Like many Geasters, it is loosened from the soil on expanding and may be rolled about by the wind when dry, the outer layer of the rays slowly wearing away in thin flakes. The range and adaptability of the species is astonishing. It is apparently world wide in distribution and almost universal in habitat. Scores may be picked up on a short walk among the sand dunes of the seashore, and it is among the commonest fungi of the high mountains. We know of no other plant of which this can be said, not even the fern Pteris. In a fresh button practically fully grown but still with white gleba, a section shows the following characters: a very thin outer flocculent layer of delicate, loosely woven fibers, which as the plant approaches maturity or is exposed, collapses almost to in- visibility and soon wears away; next a strong fibrous layer about 1 mm. thick, brownish toward the surface, whitish inward; next the horny layer which in immature buttons is very thin but thickens toward maturity to about 0.5-0.7 mm., translucent cartilage color and sharply contrasting; next a soft, pure white layer which is thickest of all (about 1.5-1.8 mm.), which splits in the middle at maturity and collapses down to a thin, scurfy layer on the inside of the rays and the softly felted, irregularly reticulated layer on the surface of the spore sac. Under the microscope it can be seen that the outer part of this layer which goes to the rays is denser, firmer, composed of fibers running parallel to the surface which in the central region turn inward and become more loosely woven. At the point where the turn is made the splitting takes place. The part remaining on the rays forms very thin reddish flakes that soon fall off. The in- nermost layer is very thin (about 0.1 mm.), translucent white, fibrous and tough; basal attachment of the spore sac 1.5 cm. wide, distinctly limited by the extent of the fleshy layer. At the base all distinct layers disappear into a homogeneous white tissue which is about 0.7-1.5 cm. wide. While the plant is often entirely subterranean until dehiscence, the mycelial attachment is confined to a basal disk one cm. or more broad, from which rather numerous, small dark fibrils extend into the soil. These are very CALOSTOMATACEAE 187 easily broken off, and after dehiscence they are usually represented only by dark col- lapsed lines over the region of attachment, giving this part a roughish appearance. Microscopic structure of the peridia is as follows: the outer fibrous layer is com- posed of small and densely packed threads, which in the outer region run parallel to the surface and curving through a right angle continue through the horny layer perpen- dicular to the surface. In this last layer the threads are straight, almost perfectly parallel to each other and very densely packed; continuing into the spongy layer they at once become looser and much more entangled. The thin inner layer of the spore sac is not vcrv different from the spongy layer, and from its surface the threads composing it pass into the gleba without obvious change to form the capillitium. Maire makes the peculiar statement that the basidia are terminated by a "sort of single compound sterigma at the top of which the spores are borne on very short pedi- cels." He gets the number of spores right. Tulasne gives the basidial shape right, but the number of spores as four. As they are of considerable interest, we quote below in full Maire's observations on this species (Comp. Rend. 131 (2): 1248. 1900): "Gcaster hygromctricus shows basidia with 2-8 spores. The fusion nucleus under- goes two successive divisions; sometimes the divisions stop there, and there are formed 4 spores, each of which receives a nucleus. At other times one or two of the 4 nuclei divided again, from which result 5 spores and 5 nuclei or 6 spores and 6 nuclei; often the 4 nuclei divide and there result 8 spores and 8 nuclei. Sometimes the nucleus of the basidium undergoes only one division, whence two nuclei and two spores. The most usual case seems to be the 6-spored basidium. On the other hand, the formation of the spores is, up to a certain point, independent of that of the nuclei: it happens, for example, that a basidium having only 4 nuclei forms 5 spores, etc. These processes are very variable, quite as in the basidia of the Cantharellaceae which we are studying at this time. However that may be, in Geaster, the formation of the spores always takes place in the following manner: at the tip of the basidium is sent out a single prolongation, a sort of compound sterigma, at the summit of which the spores are formed on very short pedicels. The nuclei, of definite number, are drawn all together into the compound sterigma, to be separated afterwards, each in its spore. In Geaster, the centrosomes and the kinoplasm are scarcely visible." For other cytological information by Maire, covering this and other species, see under Scleroderma auranlium. Up to the present the attachment of this plant to the soil has been completely misunderstood. This is hard to understand as the basal rhizomorphs are so conspicu- ous. DeBary's figure (Fungi, Myc. and Bact, fig. 146) shows no basal attachment and he says the button is attached to a felted mycelium which often spreads in the soil for the distance of an inch all around. This description completely reverses the facts and the error has never been corrected. The delicate flocculence of the surface of the buttons is so little connected with the soil that they come up almost clean. This is entirely different from the intimate attachment to the soil of the mycelial surface layer of hypogeal Geasters. It will be noted that this is an additional character pointing to a relationship with Colostoma and Tylosloma. We have examined the type of Geastrum fibrillosum in the Schweinitz Herbarium, and find that it is, as Lloyd says (Geastrae, p. 10), a weathered specimen of this species. It is the flaky roughness of the outer surface that Schweinitz referred to in his name, 188 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA not the felted reticulations of the inner peridium, as stated by Lloyd. The spores of this specimen are roughened, 7.4-10/j thick. Lycoperdon recolligens Woodward (Trans. Linn. Soc. 2: 58. 1794) seems to include both the present species and Geaster mam- mosits. He refers to Schmidel's plates 27 and 28 which are of A. hygrometricus. Illustrations: Destrie. Cited on p. 104, pi. 10, fig. B. Hard. Mushrooms, fig. 483. Hollos. 1. c, pi. 10, figs. 26-29.

Young fruit bodies formed just beneath the surface and basally attached; at maturity pushed by the elongation of the very peculiar stalk which is composed of a large number of anastomosing, firmly gelatinous strands woven together to make a spongy, more or less cylindrical column. Before elongation the entire plant is enclosed in a gelatinous layer called the volva by Burnap which at maturity becomes so watery as to fall away, exposing the spore-bearing head. This is subspherical and is composed of the outer peridium, the inner peridium, and the spore sac. The former is composed of two layers, an outer thicker one which is much like the stalk in structure and in most species becomes strongly or moderately gelatinized, and a thinner, denser inner layer which does not gelatinize. This exoperidium breaks into pieces after the plant emerges and falls off completely or in part, exposing the thin, dense, tough, and, when dry, hard and horny inner peridium which remains inflated and is very permanent. On the top of the inner peridium are elevated folds, like a puckered mouth, arranged in a more or less radiating way into several lobes which open down their centers by narrow slits leading into the spore sac within. This chamber is formed from the thin, soft and papery innermost layer of the inner peridium which is at first in contact with the next outer layer, but which soon begins to dry and contract away from the adjoining layer except above, and gradually getting smaller while hanging pendent within the firmer outer case it forces the dry spores and fragmentary remains of the accompanying fibers out of the slits for dispersal. The gleba when young has a lobulated appearance and is composed of solid masses of fertile hyphae with the basidia borne irregularly CM o < Oh o IS I < l-l OS •5 3 z < a B < u CALOSTOMATACEAE 189 throughout; between these masses run loosely woven fascicles or plates of branched threads with broad annular thickenings that are not obviously connected with the fertile hyphae and which entirely disappear before the maturity of the spores (Burnap, p. 1S3). Basidia ovate or pyriform or short-clavate, irregularly arranged throughout the fertile tissue. Spores sessile, variable in number (5-12), irregularly placed on both ends and sides of the basidia (Burnap, p. 1S5), oblong-elliptic to globose, walls usually pitted. This peculiar genus is complex in structure and very striking in appearance. The ephemeral threads with annular thickenings suggest a capillitium and are almost certainly homologous to it. They are so-called by Fischer, but it seems best to us to reserve this term for the threads found in mature fruit bodies. To say, as he does, that Colostoma possesses a well developed capillitium is misleading. In the young- est plant we have (C. cinnabarina) which is unexpanded but with spores about mature there are only a few detached fragments of this earlier system. These fragments show much narrower thickenings than those shown by Burnap. Rev. Edward Hitchcock has published a non-technical article under the head of Physiology of Gyropodium coccincum (Amer. Journ. Sci. and Arts 9: 56, pi. 3. 1825), describing a Colostoma. He speaks of the genus and species as recently established by Schweinitz, but the latter does not seem ever to have published this name, as noted by Hitchcock farther on. It does not seem to be known how Hitchcock got the name from Schweinitz. The species he described is doubtful. Burnap thinks it C. cinna- barina; Saccardo, lutescens.

Exoperidium composed of two layers, an outer, firmly gelatinous, fibrous-spongy one about 1 mm. thick when wet which is the color and consistency of the stalk and continuous with its surface, and an inner one a little less than 1 mm. thick which is clear pale yellow, opaque and much more compact and homogeneous (about like orange peel), the two layers separable without much difficulty, but dehiscing together and remaining united. After the elongation of the stem this outer peridium breaks into several (usually) irregular apical segments which fall away and into 5 or 6 or more irregular basal segments that curl outward and usually remain expanded about the base of the endoperidium like a fluted collar or less often break off close to the peridium and fall away. Endoperidium subglobose, pale orange- yellow (not red) , smooth, dull, pliable when wet, horny when dry, 1-1 .5 cm. in diameter.

O H < a, o 3 < s o H o J <: U ( ALOSTOMATACKAK 191 This is an elegant species and easily distinguished by the long stalk, light yellow color throughout except the red teeth, fluted collar, and round spores. The surface layer of the exoperidium is intermediate between that of the other two species, as it is quite obviously gelatinous but thin, and does not form a thick, clear, slimy jelly as in C. cintubarino. Schweinitz's material labelled Milremyces lutescens consists apparently of two species. There are two lots of two plants. The upper two with long stems are fused and the spore sacs are largely broken off, with no spores to be found. These, so far as they go, look just like if. lutescens. The other two consist of a smaller plant with the top nearly gone and the upper part of another with perfect sac and spores. This looks just like Rd'.rnclii, with warts on the surface of the sac, and, according to Lloyd (Myc. Xotes, p. 395), with elliptic spores. We are glad to say, however, that the part of Schweinitz's plants taken by Michener and now in his herbarium in Washington is C. lutescens as generally accepted and agree with the description, the spores being spherical, pitted, 6.5-8.2/x thick. The round spores and yellow spore sac and spores of the description (Syn. Fung. Car. Sup. No. 345) indicate clearly the species as now generally accepted. Schweinitz's figures do not show the fluted collar which is one of the most marked characters of this species (though not always conspicuous) and they may really represent C. Ravenclii. Atkinson reported this species from Blowing Rock (this Journal 9: 85. 1892), but later said that his plant was C. cinnabarina (Mushrooms, p. 213). Illustrations: Burnap. Bot.

Massee Plates 104 and 123 Rooting stem 2-5 cm. long, stout, rather compact, consisting of an interwoven mass of thick, gelatinous fibers of a soaked clay color; exoperidium light clay or straw color, not gelatinous at any stage, not obviously two-layered, surface spongy or fibrous looking, less than 1 mm. thick; on exposure breaking up into small pieces except for a larger, fluted, apical part which lifts up and falls away, the laiger particles on the sides also falling away usually, but some of the smaller ones remaining attached to the peridium for a long time until slowly worn away. In addition to these fragments which are the full thickness of the exoperidium, the endoperidium is covered with much thinner and smaller scales which are parts of the inner layer of the exoperidium from which the outer part has broken away. These scales are very persistent and are found 192 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA on almost all herbarium specimens. When the exoperidial cap falls off, that part of the inner surface which was touching the mouth ridges is seen to be red, other parts of the inner surface are a distinct light yellow, as is also the freshly exposed surface of the inner peridium, the color being due to minute, inherent, bran-like scales. These scales get larger downward and merge into the larger scales above mentioned. Endo- peridium tan or clay color, at length brown, the exposed surface dull and somewhat glaucous-looking, 7-18 mm. in diameter when fresh, 5.5-11 mm. when dry; mouth composed of about 5 rays, bright red when fresh, fading with age. Spore sac white. Spores (of No. 1488) white, clear, with one or two large oil drops, variable in size and shape, usually oblong-elliptic, a few nearly spherical, 6.5-7 x 10-1 7m; surface ap- pearing smooth except under high power, then seen to be very minutely and closely pitted, showing faint radial lines through the walls. This species is easily distinguished by the non-gelatinous exoperidium, clay colored endoperidium spotted with scales and particles, and the very faintly punctate spores. Mitremyces Tylerii Lloyd (Myc. Notes, p. 240) is probably only a small form of this species. One finds at times very small plants without obvious stalks mixed with more typical ones.

Peridium oval, 10-15 mm. broad; teeth 5-7, prominent, vermilion colored on their inner faces; exoperidium separating into numerous small hard adherent warts, covering the middle and lower surface of the endoperidium, usually entirely separating from the upper surface, leaving a smooth area on the inner peridium around the mouth. Spores white, smooth, oblong, some rarely elliptical, 6-10 x 3.5-5ji.

Ravcnclii, see Atkinson's discussion, which is rather long for quotation. The most important differences that seem to distinguish the two species are the longer stalk (on the average), the smaller spores and the vermilion color being confined to the inner faces of the stomal teeth in C. micro- sporum. We have not seen Atkinson's plants and cannot give an opinion on the validity of the species. Tennessee. Rugby. Percival, coll. (Cornell Univ. Herb., t>pe). LITERATURE Berkeley.
