Wet places and sphagnous mossy swamps. New York, Peck. Maine, Harvey. This is a small but pretty fungus which inhabits cold mossy swamps and is somewhat gregarious in its mode of growth. Sometimes it grows on decaying moss-covered sticks or prostrate trunks. The color of the spores is pecu- liar, being a dull purplish or pinkish-brown, quite unlike that of the other species. The mouths of the tubes are large for the size of the plant, and the radiating lamellz are plainly visible. The umbo is small and not always present. The red color of the pileus is apt to fade with age or to become tinged with yellow. Boletinus decipiens Px. DeEcEIvING BOLETINUS Boletus dectpiens, B. & C., Ann. Mag. Nat.

Thin woods. North and South Carolina, MA. Curtzs. Specimens of this species have not been seen by me. The authors remark that its affinities are clearly with Bo/e- tus flavidus and its allies, from which it is distinguished by its large radiating pores. They also say that when dry it is scarcely distinguishable from Paxzllus porosus Berk., except by its spores. This would imply that its stem is eccentric or lateral and I have been informed by Mr. Ravenel that it is sometimes so. But specimens of this kind, labeled Bode- tus decipiens B. & C., have been received which show by their spores that they are Paxzllus porosus. Besides, Prof. Farlow informs me that authentic specimens of B. deczpzens in the Curtisian Herbarium have only central stems, from which things I suspect that the two species have been confused. The spore dimensions here given are derived from a specimen in the Curtis Herbarium, through the kindness of Prof. Farlow. Boletinus porosus Px.

Pileus 2 to 5 in. broad; stem 6 to 16 lines long, 4 to 6 lines thick. Var. opacus (Paxillus porosus Berk. Bull. N. Y. State Mus. 2, p. 32).

Ohio, Lea, Morgan. North Carolina, Curtes. New England, fost, Farlow. Wisconsin, Bundy. New York, Peck. This species is remarkable for its lateral or eccentric stem. There is often an emargination in the pileus on the side of the stem which gives it a reniform shape. In the typi- cal form it is described as viscid when moist, and the Wisconsin plant is also described as viscid, but in all the New York specimens that I have seen it is dry and some- times minutely tomentose. I have therefore separated these as avariety. The color of the pileus varies from yellowish-brown to reddish-brown or umber. A disagree- able odor is sometimes present. The tubes are rather short and tough and do not easily separate from the hymenophore and from each other. In the young plant they are not separable. They sometimes become slightly blue where wounded. Asin other species they are pale yellow when young but become darker or dingy-ochraceous with age. The spores have been described as ‘“‘ bright yellow,” but I do not find them so in the New York plant. The plant is incongruous among the Paxilli by reason of its wholly porous hymenium, but in this place it seems to be among its true allies. BOLETUS Dut. Hymenium composed of easily separable tubes, distinct and easily separable from the hymenophore. Tubes crowded into a porous stratum without a trama, their mouths either round or angular pores. Spores normally fusiform, rarely oval or subrotund. BOLETI OF THE UNITED STATES. 8I Terrestrial, fleshy, putrescent, centrally stipitate fungz ; many of them valuable for their esculent qualities, a few potsonous. Hym. Eur. p. 495. This genus abounds in species and is related to Boletinus on one hand and to Polyporus on the other. From the latter it is distinguished by the absence of a trama and from both by the tubes being easily separable from the hymeno- phore and from each other. Some of the species are very variable, others are so closely allied that they appear almost to run together. Most of our Boleti, appear in the warmest part of the season and especially in very warm showery weather. They are scarce inadry time. In this latitude a few common species may be found from June to October, but most of them occur only during July and August. Some species, like B. edulis, B. eximius and B. felleus occasionally attain a very large size; others exhibit a singular change of color in their tubes or flesh where these have been wounded. The pileus is generally so fleshy that it is apt to be infested by the larve of insects, and that it is difficult to dry speci- mens so that they shall retain their size, shape and colors. The species are generally terrestrial, but B. hemzchrysus is habitually lignicolous, and others are occasionally so. The spores vary in color in such closely related species that this character is scarcely available for’ general classifi- cation, but it is valuable as a specific character and should always be noted. The color of the dry spores sometimes differs slightly from that of fresh ones, greenish tints often disappearing in old and dried spores. The color of the hymenium is often paler in the young plant than it isin the old one. Fries has divided the genus into two series depending on the color of the young hymenium, but this division sometimes widely separates species that are evidently closely related. It has not therefore been fully followed in the present arrange- ment. Some.of the Friesian tribes or sections also are so » 82 BULLETIN OF THE NEW YORK STATE MUSEUM. closely related and seem to blend so imperceptibly into each other that a species in some instances might with almost equal propriety be placed in either of two sections.

Tubes adnate, rarely sinuate, of one color. The viscid or glutinous character of the pileus in connec- tion with the stem and tubes distinguishes the species of this tribe. Viscid species in other tribes have the stem either bul- BOLETI OF THE UNITED STATES. 83 bous, pulverulent, lacerated or reticulated or the mouths of the tubes differently colored. In most species the viscid pellicle is separable from the flesh, which is often, in mature plants, of a soft and almost floccose or cottony texture. The tubes are generally adnate or even slightly decurrent. In the latter case the extreme top of the stem may be marked or slightly reticulated by the decurrent walls of the tubes. In rare instances the hymenium may be slightly depressed or sinuate around the stem. In some the color of the wounded tubes changes slightly, but in rare instances only does it become blue. The mouths of the tubes are often angular and the edges of the dissepiments dentate or uneven. Yellow or ochraceous hues prevail, but the young tubes are usually paler than the mature ones. The stem in some species is annulate, in others exannulate. In sev- eral closely allied central species of the tribe it, as well as the tubes, exudes drops of a thick gummy or turbid fluid which soon hardens, becomes darker in color and forms granules or glandular dots. I have not observed this char- acter in the species of any other tribe. The color of the spores as shown when shed upon white paper is some shade of yellow or ochraceous, ferruginous or brown. Several of the species have been recorded as edible. Nearly all of them occur in districts that now are, or formerly were inhabited by pine or other coniferous trees, and are wanting or scarce in other localities. The first four and several of the final species here described recede somewhat from the character of the cen- tral or typical species of the group.

This is a rare and showy species which inhabits the cold northern swamps of the country. It probably extends into Canada. When cut, the flesh emits a strong un- pleasant odor. Wounds of the flesh made by insects or other small animals have a bright yellow color. When young, the tomentose veil covers the whole plant, but, it soon parts into scales on the pileus and partly or wholly disappears from the stem. The species is apparently allied to &. trzdentinus Bres., from which it differs in the color of its flesh, veil, tubes and spores. The color of the latter is darker than in any other species of this tribe known to me. It approaches mummy-brown but has a slight purplish tint. Boletus Elbensis Px. Ex.sa BoLetus Repy237 ps 120.)

This species is so closely related to the European JB. larictnus that it might easily be considered an American form of that species or at most a variety of it. I have not seen its pileus squamose nor its stem scrobiculate and there- fore for the present keep it distinct. “The spores are a much paler brown than those of Agarzcus campestris, and incline toward ferruginous. The Friesian arrangement would require this species to be placed among the Favosi, but its affinities appear to me to be with the Viscipelles. Its locality is thus far limited to the Adirondack region of this State. Boletus serotinus Frosr Late BoLetus Bulletin Buffalo Society Nat. Sci. 1874, p. 100.

This is apparently closely related to B. elegans, from which it differs in its thick persistent annulus, in its stem which is not at all dotted and in its longer and darker colored spores. Its smaller tubes and persistent annulus separate it also from 4. flavus. In the typical form the pileus is bay-red or chestnut color, but plants growing in open places generally have it yellow or reddish-yellow. It is mild to the taste and I have eaten it sparingly.

This is one of our most common species. It is often asso- ciated with B. granulatus, from which it is easily distin- guished by its thinner more yellow pileus and more slender stem. As in that and other closely related species the stem and tubes exude a turbid juice which soon hardens and forms the granular dots or glandules seen on them. Some- times they are so numerous that they become confluent. By them and the viscidity of the pileus the fingers of the collector often become soiled and stained. The species is closely related to’ B. flavzdus, to which our plant has com- monly been referred by American mycologists, but from which it constantly differs in the character of the veil and the dots of the stem. In it the stem is dotted from top to base with persistent glandules, there is no appearance of an annulus and the veil is somewhat tomentose on the margin of the young pileus. Forthese reasons I have separated it from that species. Possibly some of the plants, referred above to B. flavzdus, belong to this species.

It is true they are closely related to each other and may possibly be regarded by some as mere varieties of a single extremely variable species, but to me, the characters that separate them, appear to be constant and decisive. Most authors, including Fries, Persoon, Cordier, Stevenson and Curtis pronounce this species edible. Gillet remarks that it should be regarded with suspicion. I have not tested it. b.

PULVERULENTI Pileus clothed with a yellow dust or a yellow pulverulent tomentum. Stem more or less yellow pulverulent, neither bulbous nor distinctly reticulated. The species which constitute this tribe are easily distin- guished from all others by the sulphur-colored pulverulence which coats the pileus and stem like a universal veil. They appear thus far to be peculiar to this country. Though strongly resembling each other in the tribal character they are very diverse in other respects. One species, by its vis- cidity, Connects with the preceding tribe; another by its differently colored tube mouths is related to the Luridi; and the third is peculiar in its ligneous habitat.

New England, Frost. This is a very distinct and very beautiful species. Mr. Ravenel remarks in his notes that “this plant is not infested by larve and preserves more constant characters than any other Boletus with which I am acquainted.” The webby powdered filaments constitute a universal veil which at first covers the whole plant and conceals the young tubes. As the pileus expands, this generally disappears from the disk, and, separating between the margin and the stem, a part adheres to each. ‘The flesh is sometimes stained with yel- low. The tubes in some instances become convex and slightly depressed around the stem. They are almost white when young, and often exhibit brownish hues where wounded. ‘The plant is sometimes cespitose.. I have ob- served a greenish tint to the freshly shed spores, but it soon ‘disappears. Boletus subchromeus Frost Ms. is this species. Boletus aurifiammeus B. & C. FLAMING-YELLOW BOoLETUS Grevillea, Vol. 1, p. 36 Pileus convex, dry, pulverulent, bright golden yellow, flesh white, unchangeable; tubes plane or convex, free, yel- low, their broad angular mouths scarlet , stem slightly taper- ing upward, pulverulent, colored like the pileus; spores .0004 to .0005 in. long, .co02 broad. Pileus 8 to 12 lines broad; stem 1 to 1.5 in. long. Woods. North Carolina, Curtzs. New York, Peck. This is evidently a rare species and as beautiful as it is rare. The whole plant is bright-yellow except the tube mouths, and is sprinkled with yellow dust or minute yellow branny particles. In the New York specimen the scarlet 106 BULLETIN OF THE NEW YORK STATE MUSEUM color is wanting in the marginal tube mouths and the stem is marked with fine subreticulating elevated lines. In other respects it agrees well with the diagnosis of the species. I am informed by Professor Farlow that according to an authentic specimen in the Curtis Herbarium, Boletus lete- color B. & C.-of Curtis Catalogue is the same as this species. SUBPRUINOSI Pileus glabrous, but more often pruinose. ‘Tubes adnate, yellowish. Stem equal, even, neither bulbous nor reticu- lated. The species of this tribe have the pileus neither viscid nor distinctly and permanently tomentose. Typically it is glabrous or merely pruinose, but Fries has admitted into the group one species with a pulverulent, and one with a silky pileus. The species are not sharply distinguished from those of the following tribes and possibly some have been admitted here which might as well have been placed there.

Though the sensitive Boletus differs considerably in some respects from the olive-red Boletus it is probably only a variety and as such I have subjoined it here. In it, every part of the plant quickly changes to blue where wounded, and even the pressure of the fingers in handling the fresh specimens is sufficient to induce this change of color. The character suggested the name given to the variety. I have not found the typical plant in New York, but specimens received from Mr. Frost are not, in the dry state, distinguish- able from the variety. oletus subtomentosus, Palmer's Mushrooms of America, Plate VII, fig. 4, appears to belong to this species. 108 BULLETIN OF THE NEW YORK STATE MUSEUM Boletus bicolor Px.

In the typical form the pileus and stem are dark red, approaching Indian red, but when old the color of the pileus fades and is often intermingled with yellow. The surface sometimes cracks and becomes rimose-areolate. From the European B.

The color of the pileus sometimes approaches wood-brown but it has more ochraceous or buff-brown in it. The fresh spores have a slight greenish or olivaceous tint, but when old and dry they have the pale ochraceous-brown hue seen in those of most species of this tribe. It has been necessary to change the name of the species, the one first given being preoccupied. BOLETI OF THE UNITED STATES 113 Boletus pallidus Frost Pate BoLetus Bull. Buff.

The subcutaneous reddish tint and the reddish chinks of the rimose pileus are distinguishing features. Wounds of the tubes sometimes become blue then greenish. Authors disagree concerning the edible qualities of this Boletus. Stevenson gives it as edible, but Cordier and Gillet say that it is regarded with suspicion. In one strongly marked form the tubes are decidedly depressed around the stem, in another the flesh is whitish tinged with red. It may be doubted whether these are varieties or distinct species.

The red mouths of the tubes are suggestive of the Luridi, but as they occur only in mature plants and are not constant, they are scarcely sufficient to place the species in that tribe. The stuffed mouths of the young tubes connect the species with the Edules but the adnate tubes prevent its association with them. Boletus subtomentosus L. SUBTOMENTOSE BoLETUS.

The pileus is usually olivaceous or yellowish-brown, but it may be reddish-brown or tawny- red. When it cracks the chinks become yellow. The stem is often attenuated downwards, but it is not always ribbed or sulcate. In one form it is marked with slight anastomos- ing lines which form broad reticulations as in B. lanatus Rost. In another form which grows on much decayed wood or stumps the pileus is dark-brown.. These may be distinct species. According to Johnson, wounds of the flesh sometimes become reddish, and according to Palmer, the ‘flesh tubes and stem change to blue wherever bruised or cut,” but I have not been able to verify these statements. The species as I understand it, may be distinguished from its near relative, B. chrysenteron, by its paler flesh, the clearer yellow tubes not changing to blue where wounded, and by the chinks of the pileus becoming yellow. The spores of the European plant have been described as yellowish-brown and as hyaline or very pale-yellow. Those of the American plant, when shed on white paper, appear to me to be ochraceous-brown. The species is recorded edible by Cordier, Curtis and Palmer. Gillet says it is only medium in quality. BOLETI OF THE UNITED STATES I19 Boletus spadiceus Scu#rr. DaTE-BROWN BOLETUS Hym. Eur. p. 503.

In wet weather the anastomosing ridges of the stem swell and become broadly winged, thereby giving the stem a peculiar lacerated appearance. The glabrous viscid pileus and the coloration of the stem distinguish the species. Boletus Betula Scuw. Brrcu BoLetus Syn. Fung.

Morganz in its tessellately rimose pileus, in the absence of greenish hues from the tubes and in its stem which is nar- rowed downward and of a uniform pale-yellow color. It is. not impossible that Schweinitz included both the preceding in his species, inasmuch as he says it was “frequent ;” and BOLETI OF THE UNITED STATES 123 there is some reason for supposing that all are forms of a single polymorphous species. The peculiar character and the great similarity in the stem of all of them are at least suggestive of a common origin if not of a unity of species. A better knowledge of these forms may perhaps lead to their union, but for the present it seems best to keep them distinct. CALOPODES Stem stout, at first bulbous, typically venose-reticulated. ‘Tubes adnate, their mouths not reddish. The reticulate stem and adnate tubes of one color dis- tinguish the species of this tribe. Inthe Luridi the mouths of the tubes are differently colored and in the closely re- lated Edules the tubes are more or less depressed around the stem or subfree, and their pores are commonly stuffed when young. Fries did not admit species with whitish tubes into this tribe, but we have done so in those cases in which this was the only character to exclude them.

The stem is generally more highly colored than the pileus and retains its color better.

The color of the tubes becomes darker with age, but it does not change to blue where wounded. The species is re- lated to the next following one with which it has sometimes been confused, but from which it is clearly distinct. The color of the spores is quite dark and approaches snuff-brown.

This species is noted for its thick, stout stem, which sometimes attains a diameter of more than two inches. It approaches the Edules in habit, but according to Gillet it is poisonous or at least to be suspected, has a penetrating un- pleasant odor and a somewhat nauseous flavor. He also describes the pores as at first whitish. The stem is some- times intensely blood-red. Boletus rimosellus wn. sp. Cuinky Bo.Letus Pileus broadly convex, flat or irregular, glabrous, Zesse/ lately vimose, dark-brown, flesh whitish; tubes adnate or sinuately decurrent, somewhat depressed around the stem, pale-yellow, becoming darker or brownish with age; stem tapering upward, broadly reticulated with brown veins, yed- lowish-white,; spores fuszform, .0006 to .0007 in. long, .co02 to .00025 broad.

I have described this species from the notes and a single dried specimen sent me by Mr. Curtis. More extended ob- servation may require some modification of the description. The color of the spores is described as brown. They are remarkable for their size. 8 128 BULLETIN OF THE NEW YORK STATE MUSEUM Boletus modestus Pr.

Miss Banning finds, in Maryland, what appears to be a form of this species in which the part of the hymenium near the stem consists of lamellae, the rest of tubes. The species needs further investigation. Boletus Curtisii Berk. Curtis BoLetus Ann. Mag. Nat. Hist. 1853, p. 13. Grevillea, Vol. I, p. 35 Pileus hemispherical or convex, vzscose, golden-yellow, tubes depressed around the stem, nearly free, their mouths umber, at length tawny; stem slender, attenuated upward, polished, reticulated, straw-colored; spores ferruginous, subelliptical, slightly attenuated at each end. Pileus 1 in. or more broad; stem 2 in. long, 2 to 3 lines thick. Pine woods. North and South Carolina, Cuvrdézs. In the original description the stem of this species is said to be hollow. The viscose pellicle indicates a relationship to the Viscipelles, with which the reticulated stem does not harmonize. The nearly free tubes point toward the Edules BOLETI OF THE UNITED STATES 129 against which the slender stem and unstuffed tubes militate. It is also incongruous among the Calopodes but as there seems to be no better place for it, we place it here for the present. Boletus griseus Frost Gray BoLetus Rep. 29, p. 45 Pileus broadly convex, firm, dry, subglabrous, gray or graytsh-black, flesh whitish or gray; tubes adnate or slightly depressed around the stem, nearly plane, their mouths small, subrotund, whzte or whztesh, stem equal or slightly tapering upward, distinctly reticulated, whztesh or yellowish, some- times reddish toward the base; spores ochraceous-brown, .0004 to .00055 in. long, .o0016 to .o002 broad. Pileus 2 to 4 in. broad; stem 2 to q in. long, 3 to 6 lines thick. ‘Thin woods and open places. New York, Peck. According to the Friesian arrangement, this species should be excluded from this tribe on account of the whitish color of the tubes; and yet it is so closely related to Boletus orna- tapes, that it scarcely differs in any respect except in color, and it might easily be considered a mere variety of that species. Such instances of close relationship have led me to disregard the division of the genus into series based on the color of the tubes. In this species the reticulations toward the base of the stem are sometimes much coarser and more conspicuous in the fresh plant than those above are, but in the dried plant the upper and finer ones are more distinct than the basal ones. This shows that the lower veins are somewhat intumescent when moist, as in the Laceripedes. 130 BULLETIN OF THE NEW YORK STATE MUSEUM Boletus flexuosipes wn. sp.

Although apparently distinct, this and the two preceding species are not sufficiently well known. EDULES Tubes subfree, rounded-depressed around the stem, their mouths not at first reddish, but commonly white-stuffed. Stem stout, bulbous as in the Luridi, but not, with a few exceptions, reticulate nor punctate-squamulose nor red. Flesh scarcely changeable. Taste pleasant. This tribe is not sharply limited but partakes to some extent of the characters of Calqpodes and Luridi. From the former, its nearly free and at first white-stuffed tubes and its generally even stem separate it, from the latter its tubes with concolorous mouths or at least with mouths not red or reddish when young will distinguish it. The species are generally of large or medium size and noted for their esculent qualities. Stem brownish-lilac or chocolate color. .........
