In the year 187G, as Microscopist of the Departmeut of Ajj^riculture, I prepared, as a part of the exhibit of my Division at the Centennial Ex- hibition at Phihulolphia, a large collection of water-color drawings rep- resenting leading types of the edible and poisonous mnshrooms of the United States, together with representations of about nine hundred species of microscopic fungi detrimental to vegetation. In the preparation of the first collection I had the valuable assistance of Prof. Charles H. Peck, State Botanist of New York, and in the second the hearty co-operation of Rev. M. J. Berkeley and Dr. M. C. Cook, the eminent British mycologists. The popular character of this exhibit attracted the attention of the general pulilic, and many letters were received at the Department show- ing an awakening interest in the study of fungi, particularly with regard to the mushroom family, as to methods of cultivation, the means of de- termining the good from the unwholesome varieties, etc. My first published paper on the subject of edible mushrooms, entitled " Twelve Edible Mushrooms of the U. S.," appeared in the annual' report of the Department of Agriculture for 1885. This was followed by others to the number of five, and as the demand for these reports increased, reprints were made and issued, by order of the Secretary of Agriculture, in pamphlet form, under the general title of " Food Products.'' Numerous editions of these reprints were issued by the Department up to 1894. During the year 1894, and the first half of 1895, 36,600 of these reports were sent out by the Department, and the supply was exhausted. They have been out of print for more than two years. It is in view of this fact, and in response to a great and constant demand for these publications, that I have undertaken to publish a series of five pamphlets on the edible and poisonous mushrooms of the United States, which shall embody the substance of the five pamphlets on " Food Products '' above alluded to, supplemented by new matter relating to classification, general and specific, analytical tables of standard authors, and a continuation of the chapters on structure, etc. Additional plates, representing leading types of edible and poisonous mushrooms, will also be inserted in each number. In the compilation and extension of this work I have the assistance of my daughter. Miss A. Robena Taylor, who has given considerable attention to the study of fungi, and who has been my faithful coadjutor in the work of collecting specimens, etc., for a number of years. For valuable suggestions as to structural characteristics and methods of classification I am especially indebted to Prof. Chas. H. Peck, of Albany, New York, Dr. M. C. Cooke, of England, and Prof. P. A. Saccardo, of Italy. The colored plates in pamphlet No. 1, together with a few of those which will appear in the succeeding numbers of this series, are reproductions of those prepared, under my direct supervision, for the pamphlets entitled " Food Products "' published by the Department of Agriculture and re- ferred to above. THOMAS TAYLOR, M. D. May 7, 1897. CRYPTOGAMS. The cryptogamic or flowerless plants, ^. e., those having neither stamens nor pistils, and which are propagated by spores, are divided, according to Dr. Hooper, into the following four classes: — Pteridophyta or vascular acrogens, represented by the ferns, club-mosses, etc. ; Bryophyta or cel- lular acrogens, represented by the musci, scale-mosses, etc. ; Algfe, repre- sented by the " Red Seaweeds," Diatomacse, etc. ; Fungi or Amphigens, which include the molds, mildews, mushrooms, etc. The lichens, accord- ing to the " Schwendener HyiDotheses," consist of ascigerous fungi para- sitic on alofae. FUNGI. Botanists unite in describing the jjlants of this class as being destitute of chlorophyll and of starch. These plants assume an infinite variety of forms, and are propagated by spores which are individually so minute as to be scarcely perceptible to the naked eye. They are entirely cellular, and belong to the class Amphigens, which for the most part have no de- terminate axe, and develop in every direction, in contradistinction to the Acrogens, which develop from the summit, possessing an axe, leaves, ves- sels, etc. Fungi are divided by systematists into two great classes : 1. Sporifera, in which the spores are free, naked, or soon exposed. 2. Sporidifera, in which the spores are not exposed, but instead are en- closed in minute cells or sacs, called asci. These classes are again subdivided, according to the disposition of the spores and of the spore-bearing surface, called the hymenium, into various families. The sj)oriferous fungi are arranged into four families, viz : 1. Hymejiomycetes, in which the hymenium is free, mostly naked, or soon exposed. Example, '•^Common Meadotc 3Iushroom.'' 2. Gasteromycetes, in which the hymenium is enclosed in a second case or wrapper, called a peridium, which ruptures when mature, thus releas- ing the spores. Example, Com.rt%on Puff Ball. . 3. Coniomycetes, in which the spores are naked, mostly terminal on in- conspicuous threads, free or enclosed in a perithecium. Dust-iike fungi. Example, Must of Wheat. 4. Hyphomycetes, in which the spores are naked on conspicuous threads, rarely compacted, Thread-like fungi. Example, Blue Mold. Of these four subdivisions of the Sporifera, only the Hymenomycetes and the Gasteromycetes contain plants of the mushroom family, and these two together constitute the class known as the Basidiomycetes. The chief distinction of the Basidiomycetes is that the naked spores are borne on the summits of certain supporting bodies, termed basidia. These basides are swollen, clulj-shaped cells, surmounted by four minute tubes or spore-bearers, called sterigmata, each of which carries a spore. See Figs. 3 and 4, Plate A. These basides together with a series of elongated cells, termed paia- physes, packed closely together side by side, and intermixed with other sterile cells, called cystidia, coustitute the spore-bearing surface or hymeuium of the plant. To the naked eye this hymenium appears simply as a very thin smooth membrane, but when a small portion of it is viewed through a microscope with high powers its complex structure is readily observed and can be carefully studied. The tSporldiferoxs fungi are represented by the families Physomycetes and Ascomycetes. The first of these consists wholly of microscopic fungi. Ascomycetes. — In the plants of this family the spores are not sup- ported upon basidia, but instead are enclosed in minute sacs or asci formed from the fertile cells of a hymenium. In this connection it would be well to state that Saccardo does not recognize the divisions Sporifera and Sporldifera by those names. They are nearly the equivalent of Basidiomycetes and Ascomycetes. What Cooke names Physomycetes, Saccardo calls Phycomycetese, intro- ducing it in his work between Gasteromycetete and Myxomycetese, which some mycologists consider somewhat out of place. Saccardo calls its asci (sacs which contain the spores) sporangia. He does not regard them as genuine asci, but as corresponding more to the peridium of the Gasteromycetece and Myxoniycetem. Peck says that this group seems to present characters of both Hypho- mycetes and Ascomycetes, with a preponderance towards Hyphomycetes. It is a small group, however, and since it consists wholly of micro- scopic fungi, need not be farther considered in this work. In the Ascomycetes are included the sub-families Discomycetes, Pyre- nomycetes, and Tuberacei. Of these the Discomj^cetes and the Tube- racei are the only groups which contain any of the mushrooms, and but few of these are large enough or sufficiently tender to possess value as esculents. A good example of the first (Discomycetes) is found in the Morel, and of the second (Tuberacei) in the Truflie. In the Discomycetes or " disk fungi," the spores are produced in minute membraneous sacs, each sac usually containing eight spores. These spore sacs are imbedded in the flesh of the exterior and upper surface of the mushroom cap. In the four classes, Hymenomycetes, Gasteromycetes, Discomycetes, and Tuberacei, therefore, are included all of the plants which are here designated under the generic term of "mushrooms." Some idea of the relative numerical value of these classes may be ob- tained from the following figures given by the distinguished British my- cologist, M. C. Cooke : " Hymeuomycetete — total number of described species 9,600 Gasteromycet^— " " " " " 650 Discomyceteaj— " " " known " 3,500 " 6 (The Tuberacei comprise a very small group of subterranean fungi, and comparatively few of the species are described.) Saccardo in his Sylloge gives a total of 42,000 described species of fungi of all classes, including the most minute. Of these the Hymeno- mycetes include by far the largest number of edible mushrooms. The family Hymenomycetes is divided into the following six orders : Agaricini, Polyporei, Hydnei, Thelephorei, Clavarei, Tremellini. In the order Agaricini the hymenium is found on the under surface of the mushroom cap, covering pleats or gills, technically called lamellae. These gills vary in character in the different genera, being " persistent in such as the Agaricus, Russula, and Leutinus, deliquescent (melting) in Coprinus, Bolbitius, etc. The edge of the gills is acute in Agaricus, Ma- rasmius, etc., but obtuse and vein-like in Cantharellus, longitudinally channelled in Trogia, and splitting in Schyzophyllum." In the Polyporei, pore-bearing milshrooms, the gills are replaced by tubes or pores. The tubes are little cylinders, long or short, pressed one against another, forming by their union a layer on the under surface of the cap, and the sj^oriferous membrane or hymenium lines their inner walls. Their upper end is always closed, while the lower extremity is open to permit the outward passage of the sj)ores. The tubes are gen- erally joined together and are not easily disunited. They are free, i. e., separable, in the sole genus Flstulina. As regards their attachment to the cap, the tubes may be firmly adherent as in the genus Polyporus or easily detached in a single ma^ as in Boletus, the fleshy form of the order Polyporei. They frequently leave a circular space of greater or less di- mensions around the stem, or they adhere to or are prolonged upon it in such a manner that the orifices rise in tiers one above another. The color of the tubes, although not offering as characteristic varieties as that of the gills, changes nevertheless according to species and according to the age of the plant. The tubes may sometimes be of a different color from their orifices, as in Boletus luridus. In some of the Boleti the color of the flesh is changed on exposure to the air and the tubes often assume the same tints. The tubes, generally called pores, are sometimes closely adherent to the substance of the cap, which is often hard, corkj^, or cori- aceous, as seen in most of the l^olyporei. In the Hydnei, spine-beari]ig mushrooms, the hymenium is seen cover- ing the spines or needle-like processes which take the place of gills in this order, and which project from the under surface of the cap. These spines may be divided or entire, simple or ramified, and are formed of the substance of the cap. lu the early stages of development they appear like small projecting points or papillae, those on the margin of the cap and at the apex of the stem being always less developed, frequently re- maining iu this rudimentary state. They are rounded in the species Hydnum imbricatum, sometimes compressed in Hydnum repandum, some- times terminating in hairs or filaments, as in Hydnum barba Jo vis, or very much divided, as in Hydnum fimbriatum. In the Clavarei, the whole plant consists of solid fleshy masses without any stem of a distinct substance, sometimes club-shaped, sometimes branched with the hymenium smoothly covering the entire surface, never inrrustii)<4- or coriaceous. In the Thclephorei, the lower surface of the cap presents neither gills, pores, nor spines, but instead the hymenium covers an uneven or slightly wrinkled surface, partially striate, sometimes obscurely papillose. The plants of this order assume a great variety of shape, from that of a per- fect cup with a central stem to an irregularly and much branched frond. They are generally dry and tough. Very few are recommended as edible. Prof. Peck says of this order that probably no edible species will be found in any of its genera outside of the genus Craterellus. In the order Tremelliui we have a great departure from the character of the substance, external appearance, and internal structure of the other orders of the Hymenomycetes. The substance is gelatinous ; the form is lobed, folded, or convolute, often resembling the brain of some animal. It is uniformly composed throughout of a colorless mucilage, with no ap- preciable texture, in which are distributed very fine, diversely branched, and anastomosing filaments. Towards the surface the ultimate branches of this filameutose network give birth to globular cells, both at their summits and laterally, which attain a comparatively large size. These cells are filled with a protoplasm, to which the plant owes its color. The fertile threads are not compacted into a true hymenium. Representative types of the above-described orders of the Hymenomy- cetes are shown in Plate B. The various genera, and species of these orders, will be described more in detail in connection with the species illustrated. CLASSIFICATION. Owing to the fact that botanists of various countries, writing in diverse languages, have for more than a century been engaged in describing the fungi of their respective countries, with their work frequently unknown to one another, it is not surprising that there has been constant revision, or that many changes have been made in the way of classification and nomenclature which to the amateur student are often confusing. The classification by the pioneer mycologist, Elias Fries, as presented in his several works on fungi, ignored all microscopical characters, and Saccardo's classification, as presented in his Sylloge F'uiigoruni, was the first complete system offered in its place. Saccardo, in 1882, commenced his Sylloge, of which not less than twelve volumes have been published. In Saccardo's system of clas- sification the six orders of the Hymenomycetes are not essentially dif- ferent in their arrangement from that of Fries, although Saccardo has raised all the subgenera of Agaricus to the rank of genera, and then altered their sequence so as to bring them into four sections, distinguished by the color of their spores. Having raised the old subgenera of Fries to generic rank, Saccardo found it necessary to limit the application of 8 I the term Agaricus to the g-roup of fungi to which it was originally ap- plied by Liunseus, viz., the common field mushroom Agaricus campester, and its allies, represented by Agaricus arvensis, Agaricus Rodmani, etc., or, as Prof. Peck more definitely states it, " to those of the gilled mush- rooms which have brown spores, free gills, a stem bearing a ring, gills generally pink- colored in the early stage, and brownish black when fully matured." M. C. Cooke, the distinguished English mycologist, prefers to retain the geJius Agaricus with its original subgenera intact, succeeded by the other genera of Agaricini, as in the Hymenomycetes Europei of Fries, giving as his reason the belief " that for purposes of classification features should be taken which are present and evident in the specimens themselves, and are not dependent on any of their life-history which can- not be presented in the herbarium." In a work such as the present, which is designed to be popular in char- acter rather than purely technical, it is deemed advisable to select as a basis for classification that system which is most accessible to reference by the general reading public. Saccardo's Sylloge, while exhaustive in character and of inestimable value to the mycologist, is written in Latin, and is, moreover, a very expensive work — facts which render it practically unavailable to the general public. In the compilation of this series of pamphlets I have adopted the classi- fication of M. C. Cooke, which, as regards the Hymenomycetes, the family containing most of the fleshy fungi, is, with exceptions noted, in accord with that of Saccardo. M. C. Cooke's hand-book of fungi is of conve- nient size and form for ready reference. For the convenience, however, of those who may wish to familiarize themselves with both systems, a synopsis of Saccardo's Genera of Hy- menomycetes will be given later. STRUCTURAL CHARACTERISTICS OF THE AGARICINI. Bj'- far the greater number of the Agaricini have both cap and stem. The form of the cap, as well as that of the stem, varies somewhat in the different genera and species. Those which are terrestrial in habit are generally of an umbrella-like shape, while those which grow upon trees and decayed tree-stumps are apt to be one-sided or semi-spherical. In many of the parasitical mushrooms the stem is absent. Where the stem is present it is either an interrupted continuation of the hymen- ophore or fleshy substance of the cap, or else is supported separately as a pillar on which the cap rests, a more or less distinct line of demarcation showing where the fibers terminate. Sometimes it is quite easily de- tached from the cap socket, as in the Lepiota procerus. It may be hollow or stuffed, solid or fibrillose. It varies in length and thickness. In some species it is smooth and polished, in others rough and hairy, reticulated, etc., sometimes tapering, sometimes distinctly bulbous at the base. The spores of the species differ in color and are usually globular or ob- long in shape. All of these characteristics assist in determining the species. MUSHROOM GILLS. Mushroom gills, or lamelljo, anatomically considered, are composed, tirst, of a central portion, a prolongation of the bymenopbore or flesh of the cap, more or less dense, sometimes so thin as to be scarcely per- ceptible; second, the hymenium or sporo-bearing membrane covering the surfaces of this prolonged bymenopbore. Tliey are vertical, simple, ecjual, respectively, or more frequently alternating with shorter gills. They are often evanescent and putrescent, sometimes liquefying alto- gether. Their color is usually ditterent from the upper surface of the cap, not always similar to that of the spores borne upon them, at least in youth ; with age, however, they usually assume the color of the mature spore. The cliange of color of the gills according to the age of the plant is very important in the study of the Agaricini ; it accounts for the white gills of certain species in youth, the pink in maturity, and the brown when aged. The end of the gill nearest the stalk of the plant is termed the pos- terior extremity ; the opposite end, the anterior extremity. In most of the Agaricini the gills are unequal. Some extend from the margin to about half the space between it and the stem ; others are still shorter. THE VOLVA. The volva is a membrane which envelops the entire plant in embryo, giving it the appearance of an egg. It originates at the base of the mushroom and furnishes it, during its foetal life, with the means of sup- port and nourishment. Its texture is so delicate that it generally disap- pears, leaving very little trace of its existence on the adult plant. In many of the volvate species this organ exists only so long as they are under gi'ound, and some mycologists restrict the term '• volvati " to such only as retain it afterwards. As the young plant expands it breaks through the top of this volva or wrapper, and, emerging, carries with it patches of the membrane on the upper surface of the cap. These are more or less prominent, numerous, and thick, sometimes irregularly dis- posed, sometimes regularly in the form of plates, warts, etc. At the base of the stem of the mushroom the remains of the volva are seen in the form of a sort of wrapper. This is more or less ample, thick, and ascend- ing. It is called free when it is loose or easily detached from the stem, and congenital when it cannot be separated from it without laceration. In some species it is distinctly membranous, and in others floccose, and friable in character, sometimes appearing in ridges as a mere border, at others broken up into scales, and, as the plant matures, wholly disappear- ing. The volva is a feature of great importance in the study of the Agaricini, of the sub-generas Amanita, Volvaria, etc. THE MUSHROOM VEIL. The veil is not a constant feature in the Agaricini, at least it is not always visible. When present it consists of a membrane which extends from the margin of the cap to the stem, veiling or protecting the gills. This membrane, called the cortina, has given its name to a numerous and 10 important class of mushrooms (the Cortinarias) . It is generally white, soft, slightly spongy, cottony, at times fibrillose or even slightly fibrous, again in texture comparable to the spider's web, and may be even powdery or glutinous. It exists intact only in the youth of the plant. It is not visible in the developing mushroom, at least while the cap is closely pressed against the stem, but as the cap expands the membrane extends and finally breaks, leaving in some species its remnants upon the margin of the cap and upon the stem in the usual form of a ring or a mere zone. When the stem is not ringed the veil rises high upon the stalk, sti'etches across to meet the edges of the cap, and is afterwards reflected back over its whole surface. MUSHEOOM SPOEES AND MTCELITJM. The spore is the reproductive organ of the mushroom. It differs from the seed of the flowering plant in being destitute of an apparent embryo. A seed contains a plantlet which develops as such. A spore is a minute cell containing a nucleus or living germ, the rei^roductive cell germ called by some authors the germinatiug granule. This in turn throws out a highly elongated process consisting of a series of thread-like cells branch- ing longitudinally and laterally, at length bifui'cating and anastomosing the mass, forming the vegetative process known as mycelium or mush- room spawn. On this mycelium, at intervals, appear knob-like bodies, called tuber- cles, from which the mushrooms spring and from which they derive their nourishment. See Fig. 5, Plate A. Where the conditions have been unfavorable this mycelium has been known to grow for years without bearing fruit. Mushroom spores are very variable in size, shape, and color, but are generally constant at maturity in the same genus. Their shape, almost always spherical in the yoang plant, becomes ovate, ellipsoidal, fusiform, reniform, smooth, stellate, sometimes tuberculate, or remains globose. This feature, varying thus with the age of the plant, should be studied in the mature plant. MYCELIUM. De Leveille has thus defined mycelium : " Filaments at first simple, then more or less complicated, resulting from the vegetation of the spores and serving as roots to the mushroom." The mycelium of mushrooms or the mushroom spawn is usually white, but is also found yellow, and even red. It is distinguished by some writers as nematoid, fibrous, hymenoid, scleroid or tuberculous, and malacoid. The nematoid mycelium is the most common. Creeping along on the surface of the earth, penetrating it to a greater or less depth, developing in manure among the debris of leaves or decayed branches, always protected from the light, it presently' consists of very delicate filamentous cells more or less loosely interwoven, divided, anasto- mosing in every direction and often of considerable extent. Its presence is sometimes difficult to detect without the use of the 11 niicroscopo, eitlier ou account of its delicacy or because of its being inter- mingled with tli§ organic tissues in which it has developed. Soniotinics mycelium unites in bundles more or less thick and branched. This has been called the fibrous mycelium. Where the filaments inter- cross closely, are felted, and inclined to form a membrane, it is hymeuoid mycelium. Where the filaments are so small and close that they form very compact bodies, constituting those solid irregular products called sclerotium, it is scleroid or tuberculous mycelium. With malacoid myce- lium Ave have nothing to do in this paper. It is a soft, pulpy, fleshy mycelium. Systematists have divided the Agaricini into groups according to the color of their spores. These groups are defined as follows by various authors : According to — Elias Fries, 5 groups : Leucospo7'us, white ; Hi/porhodms, pink ; (Jortinaria, ochra ceous ; Denninus, rust ; Pratelln, purplish bhxck. Rev. J. M. Berkeley, 5 groups : Very frequeutly pure white, but presenting also pink, various tints of brown, from yellowish and rufous to dark bister, purple-black, aud finally black; Leucospori, white; llyporhodli, salmon; Dermini, ferruginous; Prati'UiT, brown ; Coprinajius, black. Dr Badham, 6 groups ; Pure white or a yellow tinge ou drying ; brown ; yellow ; pink ; purple ; purple-black ; some pass successively from pink to purple and from purple to purple-black. Mrs.Hussey.il shades : White; rose; pale ocher; olivaceous-ocher ; reddish-ocher ; ochraceous ; yellowish olive-green ; dull brown ; scarcely ferruginous ; snuff-color ; very dark biowu.

These shades are somewhat different from the colors of the mushrooms' gills, so that, when it is of importance to determine exactly the color of the spore in the identification of a species, we may without recourse to the microscope cut off the stem of an adult plant on a level with the gills aud place the under surface of the cap upon a leaf of white paper if a dark-spored species, aud upon a sheet of black paper if the spores are light. At the expiration of a few hours we will find, on lifting the cap, 12 a bed of the slied spores which -svill represent then- exact shade. These may be removed to a glass slide and their size and form determined by means of the microscope. In the present work Dr. M. C Cooke's grouping of the spore series is adopted. ETYMOLOGY OF THE WORD "MUSHROOM." Various opinions have been offered as to the derivation of the word " mushroom." According to Hay, it probably had its origin in a combina- tion of the two Welsh words maes, a field, and rhttm, a knob, which by gradual corruption have become mushroom. Some writers on the other hand regard it as a corruption of tnoKSseron, a name specifically applied by the French to those mushrooms which are found growing in mossy places. But it seems to be of older usage than such a derivation would imply, and therefore the first explanation seems the more likely to be correct. In England the term " mushroom " has been most commonly aj^plied to the " meadow mushroom," that being the one best known ; but English- speaking mycologists now apply it generically very much as the French do the term " champignon," while the name " champignon " is restricted in England to the Marasmius oreades, or " Fairy Ring " mushroom. Berkeley says the French word " champignon " was originally scarcely of wider signification than our word " mushroom," though now classical in the sense of fleshy fungi generally. The German word J^ilz (a corruption of Boletus) is used to denote the softer kinds by some German authors. Constant and Dufour, in their recently published Atlas des Champignons, include types of a great variety of mushrooms. Hay contends that the pernicious nick-name " toad-stool " has not the derivation supposed, but that the first part of the word is the Saxon or old English " tod," meaning a bunch, cluster, or bush, the form of many terrestrial fungi suggesting it. The second sj'llable, " stool," is easily sup- pHed. " The erroneous idea of connecting toads with these plants," says Hay, " seems to be due to Spenser, or to some poet, possibly, before his time." Spenser speaks of the loathed paddocks, " paddock " then being the name given in England to the frog, afterwards corrupted to " paddic," and once received, readily converted by the Scotch into " puddick-stool." It would seem, therefore, from the foregoing, that the term " toad-stool " can have no proper relation to mushrooms, whether edible or poisonous. The three mushrooms illustrated and described in this pamphlet. Plates I, II, and III, are of the order Agaricini or gilled mushrooms. They are well-defined types and of wide geographical distribution. FOOD VALUE OF MUSHROOMS. Rollrausch and Siegel, who claim to have made exhaustive investiga- tions into the food values of mushrooms, state that " many species deserve to be placed beside meat as sources of nitrogenous nutriment," and their analysis, if correct, fully bears out the statement. They find 13 in 100 parts of dried Morchella esculenta 35.18 per cent, of protein ; in Jleloellit esciileiitd, 2(J.31 per cent, of protein, from 4(5 to 41) per cent, of potassium salts and phosphoric acid, 2.3 i)er cent, of fatty matter, and a consideral)le (juantity of sugar. The Boletus edults tliey represent as containing in 100 parts of the dried substance 22.82 per cent, of protein. The nitrogenous values of difterent foods as compared with the mush- room are stated as follows : " Protein substances calculated for 100 parts of bread, 8.03 ; of oatmeal, !).74 ; of barley bread, G.39 ; of leguminous fruits, 27.05; of potatoes, 4.85 ; of mushrooms, 33.0." According to Sehlossberger and Deppiug, in 100 grams of dried mush- rooms they found the following proportions of nitrogenous substances : Varieties. Chanterelles Certain llnssulas.... Lactarius deliciosns Boletus edulis Meadow mushroom. Grains. 3 22 4 25 4 68 4 25 7 .26 But all chemists are not agreed as to these proportions. For instance, Lefort has found 8.51 grains of nitrogenous matter in the cap of Agari- cus eampestris, 2.1 grains in the gills and only 0.34 of a grain in the stem. Payen has found 4.68 grains in Agaricus eampestris, 4.4 grains in the common Morel {Morchella esctilenta), 9.96 grains in the white truffle, and 8.76 grains in the black. A much larger proportion of the various kinds of mushrooms are edible than is generally supposed, but a prejudice has grown up con- cerning them in this country which it will take some time to eradi- cate. Notwithstanding the occurrence of occasional fatal accidents through the inadvertent eating of poisonous species, fungi are largely consumed both by savage and civilized man in all parts of the world, and while they contribute so considerable a portion of the food product of the world we may be sure their value will not be permanently over- looked in the United States, especially when we consider our large accessions of population from countries in which the mushroom is a familiar and much prized edible. In Italy the value of the mushroom as an article of diet has long been understood and appreciated. Pliny, Galen, and Dioscorides mention various esculent species, notably varieties of the truffle, the boletus and the puffball, and Vittadini writes enthusiastically of the gastronomic qualities of a large number of species. Of late years large quantities have been sold in the Italian markets. Quantities of mushrooms are also consumed in Germany, Hungary, Russia, France, and Austria. Darwin speaks of Terra del Fuego as the only country where crypto- gamic plants form a staple article of food. A bright-yellow fungus allied to Bulgarin forms, with shellfish, the staple food of the Fuegiaus. In 14 EnglaBd the common meadow mushroom Agarieiis campestris is quite well known and used to a considerable extent aniong the people, but there is not that general knowledge of and use of other species which obtains in Continental Europe. In the English-speaking countries much has been done by the Rev. M. J. Berkeley, Dr. M. C. Cooke, Worthington G. Smith, Rev. John Steven- son, Prof. Hay, Prof. Chas. H. Peck, Prof. W. J. Farlow, and others, including the various mushroom clubs, to disseminate a more general knowledge on this subject. Late investigations show that nearly all the species common to the countries of Continental Europe, and of Great Britain, are found in differ- ent localities in the United States, and a number of sjpecies have been found which have not been described in European works. The geographical distribution of many species of the mushroom family is very wide. We have had specimens of the Morel, for instance, sent to us from California and Washington, on the Pacific coast, and as far north as Maine, on the Atlantic, as well as from the southern and the midwest- ern States, and the same is true of other species. The season of their appearance varies somewhat according to the latitude and altitude of place of growth. Mushrooms are rarely seen after the first heavy frosts, al- though an exception is noted in this latitude in the species Hypholoma sublatertium, which has been found growing under the snow, at the roots of trees in sheltered woods. Frozen mushrooms of this and closely allied species have revived when thawed, and proved quite palatable when cooked. At the present time only two species, Agaricus campester and Agaricus arvensis, are cultivated in America. Some attempts have been made by an amateur mushroom club in Ohio to cultivate the Morel, but the results have not, so fai', been reported. In the meantime, however, it is well to utilize the wild mushrooms as fast as the collector can satisfactorily identify them. The woods of all moist regions of this country abound with edible varieties. Prof. Curtis, of North Carolina, gives a list of over one hundred edible species found in that State alone, and nearly all of these occur in our Northern States as well. It is not contended that this list includes all the species which may be eaten, nor have all of these equal value from a gastronomic point of view. Some are insipid as to flavor, and others are too tough or too slimy to please the popular taste. CAUTIONARY SUGGESTIONS. Befoi-e collecting for the table mushrooms found growing in the woods or fields, it would be well for inexperienced persons to consult carefully some work on the subject in which the characteristics of edible and poi- sonous varieties are described and illustrated. Considering that an opinion seems to prevail that the discoloration of the silver spoon or small white onions when brought into contact with mushrooms during the culinary process is an infallible test of the poison- 15 OUB species, I quote from a French autbor on mushrooms the following in relation to this supposed test : * * * We iHiiy not dispute the fact that a silver spoon or article of brass, or ouious, inuy not become discolored ou coutact with the poisonous i)rinciple, but this discoloration is not reliable as a test for deciding the good or bad (piality of mush- rooms. In fact, we know that in the decomposition of albuminoids sulphuicted hy- drogen is liberated which of itself discolors silver, brass, and onions. I have deemed it advisable to publish this as one of the best moans of answering those correspondents who have made inquiries as to the relia- bility of this test. It is by some supposed that high colors and viscidity are indications of non-edible species, but there are numerous exceptions here. Mussula alutacea — the pileus of which is often a purplish red — Amanita C(£sarea, and other species of brilliant coloring are known to be edible. As to vis- cidity, two very viscid species, when young, are among the highly prized esculents by those who know them, viz., FlstuUna hepatica, or the ox tongue, and llygrophorvs ehurneus, the ivory mushroom. The method of deciding the character of mushrooms by their odor and flavor is not to be relied upon. Edible mushrooms are usually charac- terized by a pleasant flavor and odor ; non edible varieties have sometimes an unpleasant odor, and produce a biting, burning sensation on the tongue and throat, even in very small quantities, but several of the Amanitas have only a slight odor and taste, and certain species of mushrooms, acrid otherwise, become edible when cooked. In fact there is no general rule by which the edible species can be dis- tinguished from the unwholesome or poisonous ones. The safest as well as the most sensible plan, therefore, is to apply the same rule as that which we adopt in the case of the esculents among the flowering plants, viz., to learn to know the characteristics of each individual species so as to distinguish it from all others. With regard to the mushrooms which have been designated as poison- ous, it should be remembered that the term " poisonous " is used relatively. While some are only slightly poisonous, producing severe gastric irrita- tion and nervous derangement, but without fatal results, others, if eaten in even very small quantity, may cause death. Happily, however, the most dangerous species are not numerous as compared with the number that are edible, and with careful attention on the part of the collector thej^ may be avoided. Since the Amanita group is made responsible by competent authority for most of the recorded cases of fatal poisoning, we would recommend the amateur mycophagist to give special study to this group in order to learn to separate the species authentically recorded as edible from the poison- ous ones. Some writers, as a measure of precaution, counsel the rejection of all species of Amanita. But this is, of course, a matter for individual prefer- ence. There would seem to be no good reason why the observant stu- dent should not learn to discriminate between the edible and the poison- 16 ous species of the Amanita as of any other group, and they should not be eaten until this discriminating knowledge is acquired. Saccardo describes fifteen edible species of this group of mushrooms. We have tested three of this number, which, on account of their abun- dance in our locality and their good flavor, we would be loth to discard, viz., A. rubescens, A. Caesarea, and A. strobiliformis. A type of the Amanita group, which is named first in the genera of the order Agariciui, is shown in Fig. 1, Plate B. By reference to this figure some of the special characteristics of the grouj) can be observed. There are mushrooms in other genera which show a volva or sheath at the base of the stem, and which contain edible species, but in these the stem is ringless. The Volvarise, for instance, show a conspicuous volva, a stem that is ringless, and pinkish spores. The Amanitopsis vaginata carries a volva, but no ring. The spores are white, as in the Amanita. In gathering mushrooms either for the table or for the herbarium, care should be taken not to leave any portion of the plant in the ground, so that no feature shall be lost that will aid in characterizing the species. In the careless pulling up of the plant the volva in the volvate species is often left behind. AGAEICINI. Fries. Ledcospoki (spores white, oe yellowish). Genus Mussula Fr. The Mussulm bear some resemblance to the iMCtars, their nearest allies, but are at once distinguished from them by their want of milk. They are very abundant in the forests and open w^oods. The genus is cited by some authors as the most natural of the agarics, but, as many of the species very closely resemble each other, it requires careful analysis to determine them. The plants of this genus are not volvate, and have neither veil nor ring. The hymenophore is not separate from the trama of the gills. Although some are pure white, the caps are usually brilliant in coloring, but the color is very susceptible to atmospheric changes, and after heavy rains the bright hues fade, sometimes only leaving a slight trace of the original coloring in the central depression of the cap. The cap in youth is somewhat hemispherical, afterwards expanding, becoming slightly depressed in the centre, somewhat brittle in texture ; gills rigid, fragile, with acute edge ; stem thick, blunt, and polished, usually short. The spores are globose, or nearly so, slightly rough, white or yellowish, according to the species. In R. virescens the spores are white, while in R. alutacea the sjDores are an ochraceous yellow in tint. A number of the species are of pleasant flavor, others peppery or acrid. Out of seventy-two described by Cooke', twenty-four are recorded as acrid. With some of these the acridity is said to disappear in cooking, and a few mycophagists claim to have eaten all varieties with impunity. We have recorded, however, some well autheiiticated cases of serious gastric dis- turbance, accompanied by acute inflammation of the mucous membrane.

The genus Jlnssnla has been divided into the following tribes or o-roups : — Compactie, Furcatst), Eigidie, Heterophylla, and Fragiles. The species Ruasida {Ri(/id(e) virescens, illustrated in Plate II, belongs to the tribe Rigidfe. In the plants of this group, the cap is absolutely dry and ri'^id, destitute of a viscid pellicle ; the cuticle commonly Ijreaking up into flocci or granules ; the flesh thick, compact, and firm, vanishing near the margin, which is never involute, and shows no striations. The gills are irregular in length, some few reaching half way to the stem, the others divided, dilated, and extending into a broad rounded end, stem solid. Plate I. Russula virescens Fries. ''The Verdette'^ or " Greenish Mtissula.''^ Edible. The cap of this species is fleshy and dry, the skin breaking into thin patches. The margin is usually even, but specimens occur which show striations. The color varies from a light green to a grayish or moldy green, sometimes tinged with yellow ; gills white, free from the stem or nearly so, unequal, rather crowded ; stem white, stout, solid, smooth, at first hard, then spongy ; spores white, nearly globose. One writer speaks of the " warts " of the cap, but the term warts, used in this connection, refers merely to the patches resulting from the split- ting or breaking up of the epidermis of the cap, and not to such excres- cences called warts, as are commonly observed on the cap of Amanita muscaria, for instance, which are remnants of the volva. The R. virescens is not as common as some others of the Russulae, in some localities, and hitherto seems to have attracted but little attention as an edible species in this country, although highly esteemed in Europe. It has been found growing in thin woods in Maryland and in Virginia from June to November, and we have had reports of its growth from New York aud Massachusetts. The peasants in Italy are in the habit of toasting these mushrooms over wood embers, eating them afterwards with a little salt. Vittadini, Roques, and Cordier speak highly of its esculent qualities and good flavor. We have eaten quantities of the virescens gathered in Washington, D. C, and its suburbs, and found it juicy and of good flavor when cooked. , Explanation of Plate I. Plate I exhibits four views of this mushroom {R. virescens) drawn and colored from nature.

COPEINAKII (spokes BLACK OR NEAELY SO). Genus Coprinus Fries. Hymenophore distinct from the stem. Gills membranaceous, at first coherent from the pressure, then dissolving into a black fluid. Trama obsolete. Spores, oval, even, black. M. C. Cooke. J| The plants of this genus have been divided into two tribes, viz., Pelli- culosi and Veliforniis. In the Felliculosi the gills of the mushrooms are covered with a fleshy or membranaceous cuticle, hence the cap is not furrowed along the lines of the gills, but is torn and revolute. In this tribe are included the Comati, Atrmnentarii, Picacei, Tomentosi, Micacio and Glahrati. In the tribe 'Veliforniis the plants are generally very small, and the cap much thinner than in those of the Pelliculosi, soon showing distinct furrows along the back of the gills, which quickly melt into very thin lines. The stem is thin and fistulose. Cordier states that all the species of Coprinus are edible when young and fresh. This is probably true, but most of them have so little sub- stance and are so ephemeral as to be of small value for food purposes. C. comatus, C. atramentarius, C. viieaceus, and C ovatus have the preference with most mycophogists, but even these soon melt, and should be gathered promptly and cooked immediately to be of use for the table. Plate II. Coprinus comatus Fries. Maned or Shaggy Coprinus. Edible. Cap at first oblong or cylindrical, then campanulate, the cuticle break- ing into shaggy fibrous scales, color whitish, the scales generally yellow or yellowish, margin revolute and lacerated, soon becoming black. Gills linear, free, and close together, at first white, then pink or purplish, turning to black. Stem hollow or slightly stuffed, nearly equal, some- what fibrillose, with bulb solid; the ring movable or very slightly adherent, generally disappearing as the plant matures. Spores oval, black, .0005 to .0007 in. long. This species is found in abundance in different parts of the United States, generally in rich soil, in pastures, by roadsides, in dumping lots, etc. Of late years quantities have been gathered in the lawn surrounding the Capitol grounds, and in the parks of the District of Columbia, as well as in the debris of the wooden block pavements used for surface soiling gardens in vicinity of the capital. They have been offered for sale in oj)€u market as low as 25 cents per pound. A correspondent from Eochester, New York, states that in a patch of his grounds which had been quarried out and filled with street sweepings the Coprinus comatus appeared in such cjuautities as to make it impossible to walk over the space without stepping upon them, and that he was able to gather from this small space from one to two bushels at a time in the spring and the fall. In flavor the C. comatus resembles the cultivated mushroom, though perhaps more delicate. Report of Microscopist, U.S. Department of Agriculture 1893. Plate II. L Krieger Pinx. COPRINUS COMATUS FR.

The Coprinus atnt- nieiiteen kept twenty-four hours before being cooked. I have not been fortunate in securing a sufficient quantity of fresh specimens to test its edible qualities personally, but the testimony received from those who have eaten it seems to point to the necessity for modera- tion in eating and care in securing fresh specimens to cook. Fig. 5. Helvella crispa. ''Crixp Ilelvella.''^ Genus Helvella Linn. The plants of this genus are usually small, though a few of the species are of good size. They are not plentiful, but they are very generally regarded as edible, the flavor bearing a resem- blance to that of the Morel. The cap has a smooth, not polished, surface, and is very irregular, revolute, and deflexed, not honeycombed like the Morel, nor showing the brain-like convolutions of the Gyromitras. Color brownish pale tan, or whitish. The stem in the larger species is stout, and sometimes deeply furrowed in longitudinal grooves, usually white or whitish. The species Helvella crispa is white or pallid throughout, cap very irregular, sometimes deeply concave in the centre, with margin at first erect, then drooping ; again it is undulating, much divided and deflexed ; in fact, so irregular is the shape that scarcely two specimens will show the cap the same in outline ; stem stout and deeply channelled. Spores elliptical, transparent. Habitat woods, growing singly or in groups, but not coespitose. Fig. 6, the ascus or spore sack and paraphesis. Genus Mitvula Fries. Soft and fleshy, simple capitate, stem distinct, hymenium surrounding the inflated cap; head ovate, obtuse, inflated. — M. C. Cooke. Cooke says of this genus that it is scarcely so well characterized as many with which it is associated, and that some of the species are evi- dently so closely allied to some of the species of the genus Geoglossum that it is difficult to draw the line of demarcation between them, particu- larly so with the species ^liivwlix pistUlaris B. from Louisiana. The plants are very small, and though none are recorded as poisonous, only one or two have any value as esculents. 8 Fig. 7. Mitrula sclerotipes Boudier. The cap in this species is small, and the stem long and slender. The spores are transparent, the asci club-shaped. The plants of this species are always found springing from an oblong sclerotium ; hence the name sclerotipes. Fig. 8 represents the sporidia enclosed in their asci with paraphyses and individual spores, the latter magnified 800 diameters. Fig. 9, sec- tional view of mature plant. Fig. 10. Mitrula vitellina Saac, var. irregularis Peck. Saccardo, in his Sylloge Fungorum, includes in this genus those having a club-shaped cap, which brings into it, with others, the species Mitrula vitellina Sacc, formerly classed in the genus Geoglossum, and its variety irregularis Peck. The latter was first described in 1879, in Peck's Thirty-Second Report, under the name Geoglossum irregulare. Prof. Peck now gives preference to the name assigned to it by Saccardo, and it is so recorded in Peck's later reports. Prof. Peck records this species as edible, and recommends it as having tender flesh and an agreeable flavor. It sometimes grows in profusion in wet mossy places, in woods, or swampy ground. It is bright yellow in color, clean and attractive. The cap is much longer than the stem, often deeply lobed, extremely irregular in outline, and tapers to a short yellowish or whitish stem. The spores are narrowly elliptical and trans- parent. The specimen illustrated is from a small one figured by Peck. The plants sometimes reach two inches in height. They are most abun- dant in temperate climates. Plate D. In Plate D are represented four species of the genus Morchella, viz., M. semilibera, M. bispora, M. conica, and M. deliciosa. Morchella esculenta is figured in Plate C. Fig. 1. Morchella semilibera De CandoUe. " Half Free MoreV Edible. Cap conical but half free from the stem as the name of the species indicates. The ribs are longitudinal, forming oblong pits ; stem hollow, much longer than the cap, white ; spores elliptical. Peck says that this species has been described by Persoon under the name Morchella hyhrida, and this name is adopted in Saccardo's Sylloge Fungorum, but most English writers prefer the first. Fig. 2.

A characteristic of this species which distinguishes it from others of the same genus is found in the number of its sporidia, spores as seen in the ascus or spore sack. In the plants of the genus Morchella the spore sacks, with one or two exceptions, contain eight spores. In the species M. hispora the spore sacks contain but two spores and these are much larger than the sporidia of those which contain eight. This characteristic, however, can only be determined by the aid of the microscope. Cooke figures a specimen taken from those published by Sorokin in Thumens Exsiccata, and calls it a variety of Morchella Bohemica Kromb. He says that it is not unusual to find M. Bohemica with two or four sporidia in some of the asci, mixed with others containing more, some specimens being entirely tetrasporus, and some, as the variety Jnspora, usually containing but two sporidia. Cooke contends that M. bispora is simply a bisporous form of Morchella Bohemica^ and calls it M. Bohemica var. hispora. It is not as common as other species. Fig. 9 represents asci of M. bispora showing the two spores in each ascus. Fig. 4. Morchella conica. ''Conical MoreV Ediblk.

AGAEICINI. Fries. Leucospori (spores white or yellowish). Genus Lactarius Fries. The plants of this genus have neither veil nor volva. They somewhat resemble the Hussuke, but can be readily distinguished from them by the greater fleshiness of the stem and by the milky juice which exudes from the flesh. The latter is a characteristic feature of the Lactars^ giving to the group its name. The species were originally arranged by Fries into groups according to the color and quality of the milk, and of the naked or pruinose character of the gills. Prof. Peck, however, considering the latter character not sufficiently constant or obvious to be satisfactory, in his early reports makes the color of the milk alone the basis of the primary grouping of the American species. Saccardo, in his Sylloge, follows Fries in his classification of the species of the genus Lactarius. In some sj)ecies the milk is at first bright colored and continues un- changed ; in others it is always white or whitish, and in others again it is at first white, changing to different hues on exposure to the air, becoming pinkish, pale violet, or yellow. lu one species (C. indigo) both plant and milk are of indigo blue. The taste of the milk varies, as does that of the flesh, according to species. Sometimes it is mild or very slightly acrid, and again it resembles Cayenne pepper iu its hot, biting acridity.

The plauts usually present a fleshy cap, the llesh quite brittle, aud breaking in clean, even fractures. In a number of the species the upper surface of the cap shows bands or zones of warm coloring, not found in any of the species of the allied genus Russula. The gills are sometimes even, more often forked, acute on the edge, color white or whitish, but changing to yellowish or reddish tints as the plants mature, or when cut or bruised. While they are at first adnate they become, with the expansion of the cap, somewhat decurrent, showing in this particular a resemblance to the plants of the genus Clitocybe. The stem is central, except in a few spe- cies, where it is eccentric or lateral, notably the latter in L. obliquus ; spores white or yellowish, according to species ; Cooke says, "rarely turn- ing yellow." They are globose, or nearly so, and slightly rough. This genus is a large one, and contains many acrid species. Out of fifty-three described and figured by Cooke, more than half are given as having the milk more or less acrid. More than forty species have been recorded as growing in this country, and many of these are extremely acrid in taste. A number of the species are edible, while others have been recorded as deleterious, poisonous, etc. L. torminosus, L. piperatus, and L. insulsus are species about which there seems to be difl'erence of opinion among authors as to their wholesomeness or edibility, some contending that, in spite of their extreme acridity, they are edible when cooked, and others that they are deleterious in their effects. L. delielosus and L. colenius have a good reputation in this country as well as abroad, and are quite abun- dant in some localities. They are more frequent in temperate climates than in northern latitudes or in the tropics. Plate V. Lactarius deliciosus Fries. '■'■Delicious Laetarhis,'" or '• Orange Milk Mushroom." Edible. Cap fleshy, viscid, at first convex, then nearly plane, becoming much depressed in the centre, funnel-shaped, marked in the adult plant with rings or rust-colored zones. Color of the cap dull orange, turning paler, aud grayish or greenish yellow when old or dried ; margin at first turned inwards; flesh whitish or tinged with yellow; gills decurrent, crowded rather thick, sometimes slightly forked at the base, pale yellow, sometimes a sattVou yellow, exuding when bruised a saft'ron-red or orange-colored liquid, hence the popular name of '' Orange Milk Mushroom ; " stem smooth, somewhat spotted, stout, stuffed with a yellowish pith, event- ually becoming hollow' ; color about the same as that of the cap. Spores subglobose, yellowish. Taste mild or very slightly acrid when raw. 12 Mycopbag-ists generally concur in the opinion that it is of very pleas- ant flavor when cooked, and some speak very enthusiastically of its escu- lent qualities. Over-cooking is apt to make it tough. I find steaming in the oven with butter, pepper, and salt, and a very small quantity of water, as oysters are steamed, a very good method of preserving the juices and flavor. It is found in Maryland, under the pines and sometimes in mossy and swampy places. Prof. Underwood, President of the New York Myco- logical Club, reports it as fairly abundant in Connecticut. Lactarius volemus Fries, the " Orange-Brown Lactar," somewhat re- sembles the L. deliciosus in shape and size, but the cap is dry and glabrous and the skin is apt to crack in patches in somewhat the same manner as does that of the Russula virescens. It is a warm orange-brown in color, varying slightly with age, and is not zoned. The gills are white or yel- lowish and crowded, adnate in the young specimens, and decurrent in the mature, exuding a white milk when bruised. The spores are globose, and white. It is found in open woods. The flavor is much like that of L. deliciosus, although perhaps not so rich. One author states it as his experience that the Lactars which have bright-coloved milk, unchanging, are usually edible and have a mild taste. L. indigo Schwein has been recorded as less abundant than some other species, but edible. The plant is a deep blue throughout, the milk of the same color and unchanging. The taste of both flesh and milk is mild. Specimens of this species were sent to me from western New York several years ago by a correspondent who found it growing in quantities In a corn field. He had cooked several dishes of it, and reported its flavor as very agreeable. L. vellereus AndJj. 2yi2^eratus are very common in fir woods. The plants are large and stout, white throughout, the milk white and excessively acrid ; gills decurrent, unequal and narrow. The milk in vellereus is apt to be scanty but copious in piperatus. Of 1j. piperatus, Woxihmgion Smith says: "So strongly acrid is the milk that if it be allowed to trickle over tender hands it will sting like the contact of nettles ; and if a drop be placed on the lips or tongue the sensation will be like the scalding of boiling water." He records it as " poisonous." Fries and Curtis say that, " notwithstanding its intense acridity, it is edible when cooked." Cordier, while recording it as edible, says thac the milk, and butter made from the milk of cows fed with it, are bitter and nauseous, although cows eat it with avidity. Gibson, while quoting one or two authors as to its edibility when cooked, says : " Its decidedly ardent tang warns me not to dwell too enthusiastically upon its merits in a limited selection of desirable esculents." The Secretary of the Boston Mycological Club, writing in the Club bulletin, says " it has been eaten as a sort of duty after the acridity was cooked out," Plate V Spores. becrion Agaricus ( Armillaria) Melleus Group from Hynesboro Park, Md., U.S. K MAYO. del CKlEM*aV/ilh«tfrHLiu%9.-Ttphv;9r:e f* 13 but does not commend it. It is spoken of as " an unattractive funp^us wbi("h usurps in the woods the place that mi^ht well be occupied by something better." In this opinion I fully concur. L. to7')ninosi/s, " Wooli/ Lactarius,'^ sometimes called the '^'^ Colic. LacUi- rins^'' has been termed acrid and poisonous by Badham. Cordier and Letellier, on the other hand, say that it can be eaten with impunity when cooked. Gillet declares it deleterious and even dangerous in the raw state, constituting a very strong and drastic purgative. One author states that, although it does not constitute an agreeable article of food, it is eaten in some i)arts of France and in Russia. Considering the difter- ences of opinion which exist with regard to this and other extremely acrid species, it would seem the part of prudence for persons with deli- cate stomachs to avoid the use of very acrid species, for, though the ac- ridity may be expelled by cooking, there would seem to be no necessity for risking unpleasant or dangerous results while the range of unques- tionably wholesome and agreeable species is sufficiently wide to satisfy the most enthusiastic mycophagist. AGARICINI. Ledcospori (spores white or yellowish). Armillaria Fries. Cooke places Armillaria in the order Agaricini, genus Agarlcus, making of it a sub-genuB. Saccardo, in taking it out of Agar- icus, elevates it to the position of a separate genus. The name Armillaria is derived from a Greek word, meaning a ring or bracelet, referring to its ringed stem. In the plants of the Armillaria the veil is partial in infancy, attaching the edge of the cap to the upper part of the stem ; the stem furnished with a ring. Below the ring the veil is concrete with the stem, forming scurfy scales upon it. The gills are broadly adnexed. In abnormal specimens the ring is sometimes absent, or appearing only in scales, run- ning down the stem. Spores white. The species are few ; eight are re- corded as growing in the United States. Cooke describes twelve species found in Great Britain. Plate VI. Ag. (Armillaria) melleus Vahl. '■'■ Honey -Coloi'eH Armillaria." Edible. Cap fleshy, rather thin at the margin, at first subcorneal, then slightly rounded, or nearly plane, clothed with minute hairy tufts : margin some- times striate, color varying, usually a pale-yellowish or honey color or light reddish brown ; tiesh whitish. Gills whitish or paler than the cap, grow- ing mealy with the shedding of the profuse white spores, and often spotted with reddish-brown stains, adnate, ending with decurrent tooth. Stem fibrillose, elastic, stuffed or hollow, ringed, and adorned with floccose scales which often disappear with age ; in some varieties distinctly bulbous 14 at the base, in others showing tapering root. Specimens occur in which the ring is wanting or only traces of it appear in the form of scales en- circling the stem. Veil usually firm, membraneous, and encircling the stem in a well-pronounced ring or collar, but sometimes filmy as a spider's web, in very young specimens hiding the gills, but breaking apart as the cap expands. Manner of growth csespitose, generally on decayed tree stumps, al- though the group figured in the plate was found growing on moist sand, mixed with clay, on a roadside in Hynesbury Park. Authors differ wideh' as to the value of this species as an esculent. I have only eaten the very young and small specimens when cooked, and found them very palatable. A Boston mycophagist records it as " very good," fried after five minutes' boiling in salted water. Prof. Peck, having tried it, considers it " a perfectly safe species, but not of first-rate quality." It is very common in Maryland and Virginia, and in the mountain districts prolific. I have talked with Bohemians and with Germans who have gath- ered it inbasketfuls in the vicinity of the District of Columbia, who speak well of it, considering it a valuable addition to the table. Its prolific growth makes it valuable to those who like it. There are no species re- corded as dangerous in this group. Ag. (Armillaria) robustus, a very stout species, with a fleshy, compact, smooth cap, bay color or tawny, occurs in the Maryland woods, and in the open woods of the Massachusetts coast. AGAKICINI. Fries. Genus CanthareUus Adans. In the plants of this genus the hymeno- phore or fleshy substance of the cap is continuous with the stem. They are fleshy, membranaceous, and putrescent, having neither veil, ring, nor volva. The stem is central, except in a few species, where it is lateral. A characteristic of the genus which separates it from other genera of the Agaricini is the vein-like appearance of the gills. They are very shallow and so obtuse on the edges as to present the appearance of a network of swollen branching veins. They are usually decurrent and anastomosing. It is a small genus. Cooke figures nineteen species. Among the de- scribed species C. cibarius is the only one whose edible qualities have been highly recommended. C. umbonatus, a very small plant, found in eastern Massachusetts is commended by those who have eaten it. The}' are usually found in woods, and amongst moss. One species, C. carhonatus, is found upon charred ground. Plate VII. CanthareUus cibarius Fries. "77tc Edible Ohantarelle." Edible.

European authors esteem it very highly, and some speak of the odor as like that of ripe apricots. The plant as found in Maryland and Virginia has a slightlj' pungent but agreeable taste when raw, and a pleasant odor when cooked. It is ranked as one of the best of the wood mushrooms by those who have eaten it in this locality (District of Columbia). It is found here in abundance, after light rains, in fir woods. Berkeley states that it is somewhat rare in England, where it is held as a delicacy, but quite common on the continent. We have had specimens from various localities throughout the States. Cooke says the spores are white. Peck and Gibson record them as yellow. I find them white, sometimes slightly tinted wdth yellow. The Chantarelle takes its name from a Greek word signifying a cup or vase, referring to its shape and possibly also to its rich golden color ; ciha- rius refers to its esculent qiialities. The variety rii/ipes Gillet closely resembles C. ciharius, but is darker, with the stem rufous, reddish, at the base. C. aurantiacus Fries bears a sufficient resemblance to C. elharlus to be sometimes taken for it, although the cap is tomentose and of a much deeper orange in tint, the gills more crowded, darker than the cap, and the stem less stout. In the variety pallidus the whole plant is very light or bufl' yellow, and the gills nearly white. C. aurantiacus has been re- corded as poisonous or unwholesome by some of the earlier authors, others say that they have eaten it, but do not commend it. RECEIPTS FOR COOKING. Stiif'td Morels. — Choose the freshest and lightest colored Morels, open the stalk at the base, fill with minced veal and bread-crumbs, secure the ends of the stalk and place between thin slices of bacon. The Morel should not be gathered immediately after heavy rains, as it becomes insipid wdth much moisture. The flavor is said to grow stronger in drying. E&calh>ped Mushrooms. — (From Mr. Frank Cay wood, Fredericktown, Ohio, November 14, 1893.) Season as directed in the usual methods for mushrooms and add a small (quantity of vinegar to hasten the cooking. Cook slowly until tender; raj^id boiling evaporates the flavor. When done, put in from a })int to a quart of sweet milk and heat. Take a pud- ding dish and put in a layer of broken crackers ; light milk crackers are the best. Put lumps of butter and pepper and salt over the crackers. Next a layer of the tender mushrooms with some of the hot gravy and milk. Continue these layers until the dish is full, having a layer of 16 crackers on top. Place the dish in the oven and bake slowly until the crackers ai'e browned. Mushroom Fritters. — Take nice large tops, season, and dip into batter and fry in hot butter as other fritters. Mushrooms en ragout. — Put into a stewpan a little " stock," a small quantity of vinegar, parsley, and green onions chopped up, salt and spices. When this is about to boil, the cleaned mushrooms are put in. When done i-emove them from the lire and thicken with yolks of eggs. The Lactarius deliciosus may be served with a white sauce or fried. Badham says the best way to cook them is to season first with pepper, salt, and small pieces of butter, and bake in a closely covered pie dish for about three quarters of an hour. The Cantharellus, being somewhat dry, requires more fluid sauce in cooking than the juicier mushrooms, and is best minced and slowly stewed until quite tender. Some advise soaking it in milk a few hours before cooking. The Italians dry or pickle it or keep it in oil for winter use. Persoon gives the following recipes for cooking the Morel : 1st. Wash and cleanse thoroughly, as the earth is apt to collect between the ridges ; dry and put them in a saucepan with pepper, salt, and parsley, adding or not a piece of bacon : stew for an hour, pouring in occasionally a little broth to prevent burning ; when sufficiently done, bind with the yolks of two or three eggs, and serve on buttered toast. 2. Morelles a V Italienne. — Having washed and di'ied, divide them across, put them on the fire with some parsley, scallion, chives, tarragon, a little salt, and two spoonfuls of fine oil. Stew till the juice runs out, then thicken with a little flour ; serve with bread crumbs and a squeeze of lemon. Mushroom Growing.* To France is due the credit of being the first country to cultivate mushrooms on a lai'ge scale, and France still supplies the markets of the world with canned mushrooms. The mushroom which is cultivated in the caves and quarries of France, to the exclusion of all others, is the agaricus arvensis (the "Snowball"), a species of field mushroom. Of late years France has found a formidable competitor in the culture of mushrooms in Great Britain. The English market gardeners find their moist, equable climate favorable to outdoor culture, and abundant crops are grown by them in the open air, chiefly, howevei', for the home market. That mushroom growing can be made a lucrative business is shown by the experience of a well-known English grower, Mr. J. F. Barter, who on one acre of ground has produced in the open air, without the aid of glass, an average of from ten to twelve thousand pounds of mushrooms annu- ally ; the price obtained for them varying according to the season, but averaging ten pence, or twenty cents, per pound for the whole year. The * A part of the matter presented under this caption was contributed by the author to the Health Magazine and appeared in the March number (1897) of that period- ical. 17 value of twelve thousand pounds of mushrooms at ten pence per pound would be .£500 sterling- or $2,500. For the purposes of (•om])!irisoii the following n,ro quoted from the Fall Mall Gazette, as exceptional prices realized in England for other fruits and vegetables in recent years : Pounds sterling per statute acre : Very early gooseberries, 100 : onions, 192 ; early lettuces, 100 ; plums, 100 ; potatoes, 100 ; strawberries, 150 : black currants, 168 ; filberts, 200. It will be seen that onions and filberts head the list, but the product of an acre of mushrooms has been shown to be worth more than double that of either filberts or onions. In the localities speciallj' favorable to hop growing 30 cwt. of hops to the acre is considered exceptional, while the average price has been quoted at 3 pounds sterling, or about one-fifth of the sum obtained from Mr. Barter's acre of mushrooms. Three months in the year the weather does not favor outdoor culture, and these months Mr. Barter spends in manufacturing brick spawn, which he exports to this and other countries. Among those who have been very successful in indoor culture are Mr. William Robinson, editor of the " London Garden," and Mr. Horace Cox, manager of the " Field." In America, where mushroom culture is still comparatively in its infancy, there have already been obtained very encouraging results by painstaking growers. Most of the cultivation has been in the northern and mid-western States, where the climatic conditions seemed most favorable to indoor culture. A few figures as to the revenue obtained in this way may be interesting to readers. An experienced Pennsylvania grower states that from a total area of 5,500 square feet of beds, made up in two mushroom houses, he obtained a crop of 5,000 pounds of mushrooms in one season, or about one pound to the square foot. These sold at an average of a little over 50 cents per pound. A third house, with 19,000 square feet of beds, produced 2,800 pounds, or one and one-half pounds to the square foot. This house yielded a net profit of one thousand dollars. This, however, can be quoted only as showing the possibilities of careful culture by experienced growers under very favorable circumstances. Amateurs could scarcely expect such good results. Three-fourths of a pound to the square foot would probably come nearer the average. A Philadelphia grower gives the average price secured from fifty shipments of mushrooms in one season at 54 cents per j^ound. New York dealers report higher rates than this. A Washington fiorist who utilizes the lower shelves of his propagating houses for the purpose of mushroom growing informed me that during two seasons he received 60 cents per pound wholesale, ship- ping to New York, and that he sold one thousand dollars worth in one season. Mr. Denton, a market gardener of Long Island, who cultivates in houses built for the purpose, markets from 1,700 to 2,500 pounds per year. Thus far the market is in the hands of a comparatively few dealers in the neighborhood of large cities, but there is certainly no good reason why the growing of mushrooms should not be more generally undertaken by the farming community. Certainly no one has better facilities than are at the command of the enterprising American farmer. On most farms the conditions are favorable or could easily be made so for mushroom cul- ture, on a moderate scale, at least. Generally there are disused sheds, old barns, etc., which with a small outlay could be transformed into mush- room houses, and where timber is plentiful the cost of building a small 18 mushroom house would be repaid by the profits accruing from the busi- ness. In the culture of mushrooms there are open, to the enterprising with small capital, four sources of profit : first, the sale of the fresh mush- rooms ; second, the manufacture of mushroom catsup ; third, the canning of the small button mushroom for exportation ; and, fourth, the manufac- ture of spawn. It is well in this, as in all new industries, to begin in a small way, and if success is attained it is easy to extend operations on a larger scale. My advice to amateu.rs is to begin with one or two beds in a well-drained cellar or shed where good ventilation and even temperature can be secured at moderate cost. In the underground cellar economy is secured by the saving in fuel. The beds can be made on the floor, flat, ridged or banked against the wall, ten or twelve inches deep in a warm cellar, and from fifteen to twenty inches in a cool cellar. The boxing for the sides and ends may be built six or eight inches higher than the beds to give the mushrooms plenty of head room. DIEECTIONS FOE PREPARING THE COMPOST FOR THE BEDS. Procure not less than a cartload of clean, fresh stable manure. Place it under cover, to protect it from rain and drain water, mix well and heap up the whole mass into a mound three feet high then beat the mound firmly down to prevent undue heating. Repeat this operation every other day until its rank smell is gone, taking care that on each turning the outside dry manure is placed in the centre of the mound. By this means the stable odor is dissipated while its heating properties are equally distributed. Add to this from one-fourth to one-fifth of clean, rich garden mould. Mix well. After this careful handling, the mass may be considered fit for bedding purposes. When placed in the beds the mass should be compacted again by beating with the back of a spade or trowel. The bed surface should appear moist but not wet, smooth and of firm consistence. From day to day it will be necessary to test its general temperature by means of a thermometer. To this end make at various places at different depths openings safii- ciently large to admit the use of a thermometer. It will be found that the temperature is highest nearest the bottom. Test at various points. At first the temperature will run high ; 105° to 120° Fahrenheit is probably as high as it will reach, but in a few days it will fall to 85° or 80° Fahren- heit. At this point spawn the bed. For this purpose make holes in the top of the bed about six inches apart and two inches deep with a blunt dibble or broom handle. Place in these holes or openings a piece of brick spawn about the size of a hen's egg, and cover the holes with ma- nure ; finish by packing the same, keeping the surface of the bed smooth and moist. The spawn should be slightl}' moistened before using. Should the surface of the bed become dry, use water from a fine spriuk- ling pan. The temperature of the cellar or house in which the bed may be placed should range between 55° and 75°, and should not be lower than 50°. If the spawn is good and all conditions attended to, the white filaments should appear spreading through the bed within eight or ten days after spawning. When the white spawn is observed on or near the surface, cover the whole surface with from one to two inches of garden loam well pulverized. A good general rule for spawning the bed is to wait until the heat of the bed is on the decline and has fallen to at least 90° Fahrenheit. If the heat in the middle of the bed runs too high the spawn is killed. Tlic experience of ;i niiinbcr of growers has shown that a bed s])awned at (10" to 80'^ and kept at 55° after the inubhrooms appear gives better results than one spawned at *.)0°. The (piality of the manure makes some difference in its temperature. That obtained from stables where horses are grass fed will be of lower normal tempeiature and will chill quicker than that obtained from corn or oat fed stock. A solution of saltpeter in proportion of about fifteen grains to a c|uart of water, occasionally spread over the bed Avith a line hose, helps to accel- erate the growth of the mushrooms. The proper condition of the manure as regards dryness or moistness can be readily ascertained by squeezing it in the hand ; it should be unct- uous enough to hold together in a lump, and so dry that you cannot squeeze a elrop of water out of it. Excessive moisture in the manure has been often a cause of failure. It should be remembered also that when the heat of the manure is on the decline it falls rapidly, five, often ten de- grees a day, till it reaches about 75°, and between that and 65° it may rest for weeks. One of the principal causes of the failure of mushroom culture in this country is the use of old or poor spawn. Good spawn should have a fresh, mushroomy odor, and a bluish-white appearance on the surface. In buying spawn one should always go to reliable seedsmen. Compost foe Mushroom Beds. Sawdust has been used in England for mushroom beds, after having been used for stable bedding, with very good results. It has also been used successfully in the District of Columbia. In fact, the very large models of cultivated mushrooms exhibited by the Division of Microscopy of the Department of Agriculture at the World's Fair in Chicago were moulded from mushrooms which were grown on the writer's premises, in a composition of sawdust stable bedding, combined with about one-fourth garden mould, but I am confident, at the same time, that much depends on the kind of timber the sawdust is made from. In this case the saw- dust came from spruce. Mushroom Culture in Canada. A Canadian correspondent informs me that he, with others, has been very successful in growing mushrooms in the open air during the summer months in Canada, and gives the following directions for preparing the beds in the colder latitudes : Place under a shed such amovmt of clean stable manure as may be re- quired for the beds, turning it over and over until all free ammonia has escaped and the tendency of undue fermentation and evolution of high temperature has greatly modified. To effect this, it is necessary to heap up the manure each time in a mound, say three feet high after turning, and beat it firmly down (the exclusion of free air prevents overheating). To put the manure in proper condition for use in the beds, from two to four weeks' treatment may be required, but much depends on the (quality of the manure and temperature of the atmosphere. Before making the beds, and several daj'S after the last turning, test the internal tempera- ture of the mound in the following manner : Make a hole with a broom- stick through the mound from top to bottom, and suspend a thermom- eter half way down in the hole for, say, an hour. The temperature may 20 be as liigb as 150° F. After tlie lapse of the time stated, beat the mound more firmly down to prevent rise of temperature. Test again two days after in the same manner. If the temperature has risen several degrees the mound must be again taken down, turned over, and remade. If, on the other hand, the temperature has fallen to 100° F., the perma- nent bed may be made. If indoor growth is desired, such as a cellar, out- building, or cave, the atmosphere must not fall below 50° F., nor be over 80° F. Air drafts cannot be permitted. The floor must be dry and the atmosphere moist. The cellar may be dark, or moderately light. Growers differ in oj^inion in this respect. Growers generally add to the the manure about one-fourth or one-fifth garden soil, but success has been attained without the use of garden soil, except as surface dressing after spawning the bed; an excessive use of loam, in any case, tends to lower the temperature too rapidly. Having prepared a box or frame-work for the bed twelve inches deep, fill it up to within two inches of the top ; beat gently down with a board, or a brick, until it is even and compact. On the following day make holes in the bed, with a dibble, ten inches deep, in which suspend a thermometer half way down for an hour. Should the temperature have fallen to 90° F., cover lightly with straw and test on the following day. Should the temperature prove to be going down, say to 80° F., or 85° F., it is safe to plant the spawn ; but should the temperature be on the rise, wait until it is falling. One grower has stated that his greatest success has been when the spawn was planted at the temperature of 75° F. Should the temperature fall too quickly and the surfare be too dr}^, sprinkle with water at blood heat, using a very fine hose, and cover the bed with straw. The spawn brick should be cut into pieces, about the size of an egg, and planted in holes made in the bed, about two inches deep and about six inches apart. The holes are then filled up and about two inches of garden soil sifted over the surface of the bed. Tamp the bed surface gently with the back of a spade. Mushrooms may be exjoected for table use in about six or seven weeks, provided the spawn is good and the tem- perature has not fallen below 50° F. In outdoor culture the beds must be well covered with straw or canvas, and had better be under a shed roof with southern exposure. The spawn used by this grower is the " brick " spawn, imported from Carter & Holborn, London, England. Cultivation or Mushrooms in Japan. The Japanese are very successful in cultivatirg a mushroom which they call " Shiitake " or " Lepiota shiitake." China also produces the same mushroom, but of an inferior quality. The Chinese therefore prefer the mushroom cultivated by the Japanese, which they import from Japan in large quantities. It is cultivated on a variety of trees, b)ut is said to grow best on the "■ Shiinoki," a species of oak (Quercus cuspidata). There are three varieties of "Shiitake,'' the spring, summer, and autumn crops differing somewhat in quality. The method of growing the " Shiitake " is given by the Japanese Commissioner of Agriculture as follows : " Trees of from twenty to fifty years' growth are cut down at the ap- proach of winter when the sap has ceased to run, and after the lapse of twenty or thirty days, according to the condition of the drying of the wood, are sawed into logs of 4 or 5 feet in length. Into each of these logs incisions are made with a hatchet, at intervals of about 6 inches, and they are piled regularly upon a frame-work erected at a height of about 21 1 foot above the ground, under the trees. The location of the ground selected for piling the logs should be the slopes of a forest, facing south- east or southwest. After keeping the logs as above described for from two to three years, they are immersed in water for twenty-four hours in the middle of November, and again laid one upon another for about four (lays ; if it is in a cold district, the pile is covered with straw or mats. At the expiration of the fourth day the logs are oblitpiely tilted against l>(iles fixed horizontally to the trees at a height of about 4 feet in a well- \ ( utilatod and sunny situation. The mushrooms soon appear in quantity, and, after twenty or thirty days' growth, are ready for harvesting." Recent reports of the Japanese Agricultural Department show the total value of the annual exjjort of " Shiitake " to be nearly five hundred thou- sand "yen " (silver). Manufactuke of Spawn. As many tons of artificial spawn are yearly imported into this country, it would seem that the manufacture of spawn in the United States might prove a profitable form of investment. "Brick Spawn." For commercial purposes the English method of making the spawn into bricks has some advantages over the French " Hake " process. Its com- pact and uniform shape makes the brick more convenient for storage and general handling, and greatly facilitates its transportation to l»ng dis- tances. Brick spawn is made in the following manner : Clean horse drop- pings, cow manure, loam, and road sweepings are beaten up in a mortar- like consistency and then formed into bricks, moulds being used, slightly differing in shape with different makers, but usually thinner and wider than common building bricks. The following proportions are given: (1) Horse droppings the chief pai't ; one-fourtli cow dung ; remainder loam. (2) Fresh horse droppings mixed with short litter for the greater part ; cow dung, one third; and the rest mould or loam. (3) Horse dung, cow dung, and loam, in equal parts. When about half dry, depressions are made in the bricks, sometimes in the centre, and sometimes in each corner, and small pieces of good spawn are placed in these depressions, and plas- tered over with the material of the brick. The cakes are then laid out to drj^ standing on their edges, and when nearly dry are piled in pairs with the spawn-larded surfaces face to face. The bricks are then stacked away, and covered with sweet fermenting litter, sufiiciently to cause a heat of 60" F. It should not be over 70° F. One spawn manufacturer says that the most rapid and successful growth of the mycelium is attained when the temperature is from 63° F. to 67° F. The bricks are examined frequently during the process, and when the mycelium of the old spawn has permeated the whole mass like a tine white mould, the bricks are taken out and dried in a well-ventilated dark place. They are then placed in a cool, dark storehouse, where they are not subject to dampness and where the temperature is about 50° F., not over 65 " or below 35° F. Slight ven- tilation is necessary, but not enough to make the bricks dust-dry. Keep- ing the spawn dry merely suspends its growth ; as soon as it is again submitted to favorable conditions of moisture and heat, its pristine activity returns. Dampness, combined with heat, stimulates the growth of my- celium : frost also destroys the vitality of the spawn. It is evident, there- fore, that these conditions should not exist in the store-room. One manufacturer advocates piling the bricks, after spawning, on a clay floor, packing closely four bricks deep, and covering them with sifted 22 loam. By this method it is claimed that danger of " fire fang " will be avoided, as the bricks will be kept at a perfectly uniform temperature of about 60° or 66°, which causes the spawn to run quickly and uniformly. In from four to sis weeks they are ready to take out and dry for use or storage. The French or " Flake " spawn comes in light masses of loose, dry litter. It is obtained in the following way : A bed is made up as if for mushrooms in the ordinary way, and spawned with " virgin " spawn, and Avheu the bed is thoroughly impregnated with spawn, it is broken up and set aside to dry. This spawn is usually sold in small boxes, containing from two to five pounds, but it also can be obtained in bulk when it is purchased by weight. The French or " flake " spawn is much more ex- pensive than the English or " brick " spawn. It is claimed by some very successful growers, who have tried both, that the brick spawn produces heavier and fleshier mushrooms than the French " flake.'' " Mill Track " Spawn. ' " Mill track " spawn was formerly considered the best in England, but since horse power has given jjlace to steam power in the mills there is now no further supply of mill track, and it is practically superseded by the "brick" spawn. The real " mill track " is the natural spawn that has spread through the thoroughly amalgamated horse drojjpings in mill tracks, or the sweepings from mill tracks. Spawn Peoduged in a Manure Heap. During the past year I have made some experiments in the pine and oak woods of Hynesboro' Park, Maryland, with relation to spawn culture, an account of which may prove of interest to students in this line of in- vestigation. Several loads of stable manure and oak-leaf bedding were well mixed and formed into a mound about three feet in height, having a diameter of six feet, and tapering to about four inches in depth at the outer edge. The mass was quite moist and slightly tamped to give it general consistency. It was exposed to the open air, without protection, during the months of September, October, and November. In the mean- time, frequent rains occurred. On examination it was found that the rains did not penetrate to a depth of more than four inches. On opening up the centre of the mound, it was observed that the portion thus exposed consisted of highly decomposed leaves, and presented a white mass of matted, " burned " mycelium. It was evident that the temperature at that point had risen considerably above 100° Fahr. The mycelium was, doubtless, produced in abundance before the temperature reached 100 Fahr. and became scorched as the temperature increased. On examining the outer edges, where the depth was only twelve inches, I found an abundance of mycelium which did not show any appearance of having been scorched by undue temperature. Since no mycelium had been added to the mound, it is evident that the spores which produced it must have been present, although unobserved, and awaiting only the proper conditions for development, i. e., for budding and the production of myce- lium. At the end of the third month, groups of the common meadow mushroom, Agaricus campestris, together with some fine examples of Tricholoma terreum, an edible mushroom, common to these woods, ap- peared on the edges of the mound.

Fasciculares. — Pileus smooth, tough, bright colored when dry, not hygrophanous. Examples, Ag. (Hypholoma) .nchhtteritbis and Ag. (Hypiholoma) fascicular is. 2. Yiscidi. — Pileus naked, viscid. Example, Ag. (Hyj^holoma) ///'//iii/ii/\. Fries .vanely iiiiii/ii\ Peck. Figured from specimens collected in the District of Columbia arisiug from the attucbment to it of fragmonts of the veil, but usually it is ringless. The typical sj^ecies of Hyplioloma have the fleshy part of the cap con- fluent with the stem, but in H. uieertnm the stem is not confluent and is easily separated from the cap as in the Lepiotas. This mushroom was iirst recorded by Peck in his early reports as the variety " incertus " of the species Agaricus (Hypholoma) Candolliauus, but has since been re- corded by Saccardo as a distinct species, Hypholoma incertum. Two species of Hypholoma have the same habit and sufficiently resem- ble incertum to be taken for it, if not carefully examuied as to points of difference. These are H. Candolliauinn, named in honor of A. De Can- dolle, and H. uppendicnlatum. In the first named of these two species the cap is whitish, the gills at first violet in color, changing to dark cinna- mon browu. In H. appeudiculatum the pileus is rugose when dry, and sprinkled with atoms. It is darker in color than that of H. incertum ; Cooke says tawny or pale ochre ; Massee says bay, then tawny. The gills are sub-adnate, in color resembling those of H. incertum ; stem slender, smooth, and white. From the foregoing it will be seen that H. incerUmi agrees more nearly with H. Candollianum in the color of the cap, but more nearly with H. appendicidatUDi in the color of the gills. Saccardo recognizes the three as " distinct species of the genus Hypholoma^ As all are edible, the slight differences observed are interesting chiefly to the mycologist. The mycophagist will And them equally valuable from a gastronomic point of view. In taste they resemble the common mushroom. They are more fragile, however, and require less cooking than the cultivated mushroom. Broiled on toast or cooked for ten minutes in a chafiing dish, they make a very acceptable addition to the lunch menu. The specimens figured in Plate IX were selected from a crop of thirty or more growing in the author's garden, in very rich soil at the base of a plum-tree stump. For several seasons past small crops have been gath- ered from the same spot, as well as around the base of a flourishing peach tree. Quantities of all three species have been gathered in the short grass of the Capitol grounds for a number of seasons, and in the various parks of the District of Columbia. Specimens have been received from western New York and Massachusetts. Those growing upon soil very heavily fertilized are apt to be somewhat stouter and shorter stemmed than those coming up through the short grass in the parks. ANALYTICAL TABLE. The following compendious analytical table showing prominent charac- [teristics of the leading genera and subgenera of the order Agariciui, ac- 1 cording to Fries, Worthington Smith, and other botanists, which appears [in Cooke's Hand Book, revised edition, will be found helpful to the col- I lector in determining the genus to which a specimen may belong. 6 Order Agaeicini.

Gills decurrent GOMPHIDIUS Gills not decurrent. Pileus striate P.mthyrdla Pileus not striate PcdkvoIus In the Friesiau classification which, with modifications, has prevailed for many years among- mycologists, the c/enus Agaricus included in its subgenera the greater part of the species of the order Agaricini. The 8 subgenera, printed in the above table in italics, were included in this genus. The genera are printed in capitals. In the Saccardian system, all the subgenera of Agaricus having been elevated to generic rank, the term Agaricus is limited to a very small group which includes the sub- genus Fsalliota of Fries, the si^ecies being characterized by fleshy caps, free gills, ringed stem, and dark brown or purplish brown spore-s. As restricted, it naturally falls into the spore series Melanosporece. In the white-spored section, Leucospori, the recorded edible species occur in the following genera : Marasmius, Cantharellus, Lactarius, Russula, Hygrophorus, Collybia, Pleurotus, Clitocybe, Tricholoma Armillaria, Lepiota, and Amanita. The plants of Marasmius are usually thin and dry, reviving with moisture. Cantharellus is characterized by the obtuseness of the edges of the lamellse, Lactarius by the copious milky or sticky fluid which exudes from the plants when cut or bruised. Russula is closely allied to Lactarius, and the plants bear some re- semblance in external appearance to those of that genus, but they are never milky, and the gills are usually rigid and brittle. In Hygrophorus the plants are moist, not very large, often bright colored, and the gills have a waxy appearance. The Collybias are usually csespitoso, the stems exteriorly cartilaginous, in some species swelling and splitting open in the centre. In Pleurotus the stem is lateral or absent. The plants are epiphytal, usually springing from the decaying bark of trees and old stumps. In Clitocybe the plants are characterized by a deeply depressed, often narrow cap, with the gills acutely adnate, or running far down the stem, which is elastic, with a fibrous outer coat covered with minute fibres. Many of the species have a fragrant odor. The Tricholomas are stout and fleshy, somewhat resembling the Russulas, but distinguished from them by the sinuate character of the gills, which show a slight notched or toothed depression just before reaching the stem (represented in Fig. ■1, Plate IV). Typical species of Armillaria show a well-defined ring and scales upon the stem, the remains of the partial veil, and the plants are usually large, and csespitose. The Lepiotas are recognized by the soft, thready character of the fleshy portion of the cap, and the fringed scales formed by the breaking of the cuticle. The ease with which the ringed stem is removed from its socket in the cap is another character- istic which distinguishes the plants from those of other genera. The Amanitas are distinguished by the volva, which sheathes the somewhat bulbous stem at its base and the ring and veil which in the young plant are very distinct features, the whole plant in embryo being enveloped in the volva. The Amanita group, besides containing some very good edible species, is also credited with containing the most dangerous species of all the mushroom family, and some which are undoubtedly fatal in their effects.* "A more detailed description of this group will appear in No. 5 of this series. I 9 The Nyc-tali are miuute mushrooms parasitic on other mushrooms. In OmpliaHa, the plants are (juite small, with membranaceous caps, gills truly decurrent, and cartilaginous stems. The Mycene;e are generally very small, slender, and fragile, usually cn'spitose, with bell-shaped caps, sinuate gills, not docurrent, and car- tilaginous stems. In some species the ]ilants exude a milky juice. In the gcnei-a Panus, Lentinus, Leuzites, Sehizophylluni, Xerotus, and Trogia, the plants are leathery or cori.ceous, dry and tough, and though none are recorded as poisonous, they are too tough to be edible. The mushrooms having pink or salmon colored spores, section Rhodo- sporhii, form the smallest of the four primary grouj^s of Agaricini, the number of known species not exceeding 400, and most of these are taste- less, or of disagreeable odor, while some are recorded as unwholesome. The species are pink-gilled when mature, though often white or whitish when very young. The recorded edible species are found in Volvaria, Clitopilus, and Pluteus. The Volvarise are characterized by the very large and perfect volva which wraps the base of the stem in loose folds, the ringless stem, and the pink, soft, liquescent gills, which are free and rounded behind. The cap is not warted : in some species it is viscid, and in honihychms, recorded by several authors as edible, and by some as doubtful, it is cov- ered wdth a silk}' down. In Clitopilus the odor of the edible species is more or less mealy. The cap is fleshy, and the margin at first involute. Two edible species which closely resemble each other — viz., Clitopilus prunulus, " Plum mushroom," and Clitopilus oi'cella, " Sweetbread mushroom," — are highly recom- mended for their delicacy of flavor. In Leptonia most of the species are small, thin, and brittle, correspond- ing with Mycena in the w'hite-spored series, and with Psathyra and Psathyrella in the dark-spored series. Eecilia corresponds with Omphalia. Claudopus corresponds Avith Pleurotos in its habit of growth and lateral stem, difl^ering in the color of the spores. Annularia includes only a few small species having a ringed stem, no volva, and free pink gills. Cooke says of this subgenus that no British species are known. The recorded species of Pluteus have their habitat on tree stumps, sawdust, or upon fallen timber. One species, Pluteus cervhnis, is recorded as edible, but not specially commended. Of Entoloma, Worthington Smith says, " It is allied to Tricholoma, though most of the species are thinner and often brittle. It agrees also in structure with Hebeloma and Hj'pholoma." None of the species are recorded as having value as escu- lents. The genus Bolbitius is described by Cooke as a small genus inter- mediate between Agaricus and Coprinus on the one side, and Coprinus and Cortiuarius on the other. The species are small and ephemeral. 10 Saccardo places Bolbitius in his division Melanospoi'Be, although the spores are ochraceous. In the section Pratelli Psalliota and Hypholoma contain mushrooms which are of exceptionally fine flavor. In the first of these is found the common field mushroom Agaricus campester and its allies. The black-spored section Coprinarii contains two genera which include a few recorded edible species, viz., Coprinus and Gomphidius. The Psa- thyrellas correspond in size to the Mycenas in the white-spored series and to the Psathyras in the purjole-spored section ; the gills are free or adnate and turn black when mature. None of the species are edible. In Paneolus the plants are somewhat viscid when moist, the gills are described as " clouded, never becoming purple or brown." They are usually found on manure heaps near cities. None are edible. Saccardo in his Sylloge combines the Pratellse and Coprinarii, making of them one section which he calls MelanosporecB. G. Massee, the British mycologist, makes of the black-spored and the purple and purplish-brown spored series two divisions, calling them, re- spectively, Porphyro&porem and Melanosporeoe. The recorded edible species of the spore section Dermini are found in Pholiota, Cortinarius, and Paxillus. The larger proportion of the Pholiotas grow upon tree stumps. They have a fugacious, persistent friable ring, and are liable to be confused with the Cortinarii, unless at- tention is paid to the spidery veil and the iron-rust tint of the spores of the latter. Only a few of the species are recorded as edible, but none are known to be poisonous. Cortinarius is a large genus. It contains a larger pi'Ojjortion of edible species than Pholiota, and none are recorded as poisonous. The cobweb-like veil which extends from stem to margin of cap in the young species, and the rust-colored spores which dust the gills as the species mature, distinguish the genus from all others. A characteristic feature of Paxillus, and one which makes it easily dis- tinguishable from others of the same group, is the ease with which the gills as a whole can be separated from the substance or fleshy portion of the cap. There is an exception to this in the species Paxillus involutus, recorded by Peck as edible. POLYPOREI. Hymenium lining^ the cavity of tubes or pores which are sometimes broken up into teeth or concentric plates. — Berkeley's Outlines. The plants of this second primary group or order of the family Hy- menomj'cetes exhibit a greater dissimilarity of form and texture than do those of the Agaricini. Some of its genera consist almost wholly of coriaceous or woody plants. A few contain flesh}'^ ones. Some of the species have a distinct stem, while others are stemless. With regard to the receptacle in the plants of the genera Boletus, Stroblloniyces, etc., it forms a perfect cap, like that of the common Agaric, a cushion of tubes taking 11 the place of gills on the imhureus Fries is perhaps the one most likely to be selected for table use, the others becoming very quickly indurated or tough, and this should be gathered when very young, as in maturity it loses its fleshy consistency and becomef iry and tough. It is common on old tree stumps and is often found on the dead wood of living trees, the bright yellow and vivid orange red tints which characterize the young plant making it very conspicuous. It is easily recognized by its irregular, closely overlapping frond-like caps, white flesh, and the very small sulphur-yellow tubes. The sj)ores are white, elliptical. The flesh of young specimens is somewhat juicy. The geograjihical distribution is wide, and in places where a moist, warm temperature prevails plants of this species often attain very large proportions, sometimes completely encircling the trunk of a tree at its base.

Of the genus Fistulina but one species, Fistulina hepatica, figured in Plate X, is recorded as edible aud indigenous to this country. Plate X. Fistulina hepatica Bull. ''Beefsteak Mushroo7n,'^ ^' Live)- Fiiriffus.^^ Edible. Genus Fistulina Bull. Hymeuophore fleshy, hymenium infei'ior, that is, on the under surface of the cap, at first papillose ; the papilhe at length elongated, and forming distinct tubes. Besides Fistulina hepatica, five species of this genus are recorded in Saccardo's Sylloge, viz., F. radieata Schw., F. spathidata B. & C, F. pal- lida B. & R., F. rosea Mont., and F. antarcUca SjDeg. ; the last indigenous to Patagonia. F. hepatica is the only species with which I am familiar. The plants of this species are very irregular in form, rootless, epyphytal, often stem- less, and sometimes attached to the matrix by a very short stem. This fungus is frequently found upon old oak, chestnut, and ash trees, develop- ing in the rotting bark. It apj^ears first as a rosy pimp)le, or in a series of red granules. In a very short time it becomes tongue- shaj^ed, some- times kidney-shaped, assuming the color of a beet root. As it increases in size it changes form again, becoming broad in proportion to its length, and changing in color to a deep blood-red, and finally to a dull liver tint. Its lower surface is often paler than its upper, it being tinged with yellow and pinkish hues. One author states that it requires about two weeks to attain its highest development, after which it gradually decays. It varies in size from a few inches to several feet in circumference. Eev. M. J. Berkeley mentions one which weighed thirty' pounds. It has been styled the '■^poor 7na)is fungus,'" and in flavor resembles meat more than any other. The substance is fleshy and juicy in the early stage. The j^ileus is papillose, the papillpe elongated, and forming distinct tubes as the pileus expands. These tubes are separable from each other, and with age be- come approximate and jagged at their orifices. The tubes are at first yellowish, with a pink tinge, becoming dingy with age. The fleshy sub- stance, or hymenophore, is often veined in light and dark red streaks. The juice is pellucid, red, and slightly acid. Spores at first nearly round, becoming elliptical, salmon color. 4> 14 This fungus is esteemed in Europe, where it is eaten prepared in a va- riety of ways. When young and tender it can be sliced and broiled or minced and stewed, making a delicious dish. When too old the stock is rather tough for good eating, but the gravy taken from it forms a rich flavoring for a vegetable stew or a meat ragout. The following recipe for cooking this mushroom has been recommended : Slice and macerate it, add pepper and salt, a little lemon, and chopped onions or garlic : then strain and boil the liquid, which makes most excellent gravy, resembling that of good beefsteak. The Fistulina hepatica is well known in Europe, and is found in differ- ent parts of the United States, in some places growing abundantly. I have gathered some fine specimens in Maryland and Virginia, but none as large as that described by Dr. Berkeley. KECIPES FOE COOKING MUSHKOOMS. To Pot Mushrooms. — The small oj)en mushrooms suit best for potting. Trim and rub them ; put into a stewpau a quart of mushrooms, 3 ounces of butter, 2 teaspoonfuls of salt, and half a teaspoonful of cayenne and mace, mixed, and stew for ten or fifteen minutes, or till the mushrooms are tender ; take them carefully out and drain them jjerfectly on a slojjing dish, and when cold press them into small pots and pour clarified butter over them, in which state they will keep for a week or two. Writing- paper placed over the butter, and over that melted suet, will efl:ectually preserve them for weeks in a dry, cool place. To Pickle Mushrooms.— Select a number of sound, small pasture mush- rooms, as nearly alike as possible in size. Throw them for a few minutes into cold water, then drain them, cut off the stalks, and gently rub off the outer skin with a moist flannel dipped in salt ; then boil the vinegar, adding to each quart two ounces of salt, half a nutmeg grated, a dram of mace, and an ounce of white pepper corns. Put the mushrooms into the vinegar for ten minutes over the fire ; then pour the whole into small jars, taking care that the spices are equally divided ; let them stand a day, then cover them. Baked Mushrooms. — Peel the tops of twenty mushrooms ; cut off a portion of the stalks and wipe them careful!}' with a piece of flannel dipped in salt. Lay the mushrooms in a tin dish, put a small piece of butter on the top of each, and season with pepper and salt. Set the dish in the oven and bake them from twenty minutes to half an hour. When done, arrange them high in the centre of a very hot dish, pour the sauce around them, and serve quickly and as hot as you possibly can. Mushroooms with Bacon. — Take some full-grown mushrooms, and, having cleaned them, procure a few rashers of nice streaky bacon and fry them in the usual manuer. When nearly done add a dozen or so of mush- 15 rooms and fry them slowly until they are cooked. In this process they will absorb all the fat of the bacon, and with the addition of a little salt and popper will form a most appetizing; breakfast relish. JlKs/irootii l*le. — A very good mushroom pie is made in tlie following manner : Chop a quart of mushrooms into small pieces, season to taste, and add one pound of round steak chopi^ed line and seasoned with a small i^iece of onion. If the steak is lean, add a small piece of suet, unless butter is preferred to give flavor. Put the chopped steak and mush- rooms in deep saucepan with cover, and stew slowly until tender. jMake a crust as for beefsteak pie and put in a deep earthern dish, lightly brown- ing the under crust before adding the stew, and cover with a crust lightly punctured. In some parts of Russia mushrooms form an importatnt part of the diet of the people, especially during the Lenten season, when the fast of the Greek church is yexj strictly kept, and meat, fish, eggs, and butter are forbidden. Provision is made for this season in the securing of quantities of dried and salted mushrooms, which are cut up in strij^s and made into salads with a dressing of olive oil and vinegar. The poorer classes to whom the olive oil is unattainable use the rape seed and other vegetable oils in the cooking of their mushrooms. The following recipes are translated from a recently published Russian work on the subject of mushrooms, cultivated and wild : Select fresh, sound Boleti, cut off the caps, and, after wiping clean with a napkin, place them in a sieve, pouring over them scalding water ; when thoroughly drained, leave them where there is a free current of air until perfectly dry. Next string them upon stout twine, leaving spaces be- tween to allow of free circulation of air. If convenient, they can be dried artificially by placing in a not too hot oven with the door open. Dried by either method, they can be kept all winter. Before using, they should be soaked in water or milk until soft. In this condition they make very good flavoring for soup or gravy, and can also be used as filling for pies. 3fns/iroo)>iS Cooked in Butter. — Wipe the mushrooms clean and dip in dry flour. Heat a quantity of butter to boiling temperature in a sauce- pan, seasoning with a small piece of onion. Drop the flour-covered mushrooms into the boiling butter, shaking the pan constantly over the fire. When the mushrooms are cooked add sour cream to taste. Before serving, sprinkle with grated muscat nut. J/ushrooin Vickie. — Select only young button mushrooms. Put them for a few moments in boiling water lightly salted and vinegared. Boil vinegar (only the best should be used), spicing it according to taste. Al- low the vinegar to cool. Put the mushrooms in layers in a jar and pour over them enough spiced vinegar to cover. Seal tightly. Salted Piperltes. — Only the caps are taken of the Lactarius piperites. They are placed first in salted scalding water for several minutes. The water is then gently pressed out with a napkin, the mushrooms are 16 placed on sieves and cold water poured over them. They are then placed in layers in a jar, each layer sprinkled with salt, and whole pepper and minced onion scattered over the layer. When the jar is full a thin round board is placed upon the top layer and pressed down with weights, and as the mass gives way mushrooms are added until the jar is compactly filled. The jar is then covered with parchment or otherwise tightly sealed. Eight gallons of mushrooms require from one to one and a half glasses of salt. This makes a good salad when treated with oil. Note. — L. piperites is an extremely acrid mushroom when in the raw- state, and the Russians do not stew it, but prepare it in the above way, taking the precaution to scald thoroughly with salted water before putting away. The precaution of scalding through several waters is a wise one to use in the preparation of all mushrooms inasmuch as the poisonous principle of most mushrooms is soluble in scalding water. Dilute vinegar is frequently used in the same manner. Vinegar should not be used in metal vessels unless porcelain-lined. LIST OF THE GENERA OF HYMENOMYCETES.

Dr. Brefield's exhaustive investigations into the life-history of fungi in general have been such as to entitle his views to consideration, although the system presents some inconsistencies which may prevent its adoption in its entirety. According to the Brefield system, as summarized by his colleague Dr. Von Tavel, Fungi are divided into two primary classes : (1) the Phycomy- cetes, or lower fungi nearest like the algse, consisting of a one-celled thai- las vnth sexual as loell as nonsexual modes of rejyroductioot, and (2) the Mesomycetes and the Mycomycetes, having a divided or many celled thallus, propagated by non-sexually formed spores. The Phycomycetes are further divided into two large sections, based on their methods of reproduction, termed, respectively. Zygomycetes and Oomycetes. These include the old typical Mucors, the Peronosporese or " rotting moulds," once classed with the Hyphomycetes, the SajDrolegniacese, " Fish Moulds," of aquatic habit, the Entomophthoracese, " Insect Moulds," together with some minor groups. The Mesomycetes connect the Phycomycetes with the Mycomycetes. The class Mycomycetes is primarily divided into two sections, viz., Ascomycetes and Basidyomycetes, with the Ustilaginese, " Smut Fungi," in Mesomycetes, forming a transitional group between Phycomycetes and the Basidiomycetal group of the higher fungi. The Ascomycetes are primarily subdivided into Exoasci and Carpoasci, groups based on the character of the asci. In the first, JExoasci, the asci are naked and borne directly on the myceluim : in the second, Carp>oasci, they are enclosed in a wrapper composed of fertile hyphse and sterile threads, having also accessory fruit forms. The first includes Endomy- cetes and Taphrinefe. In the second are included the groups Gymnoasci, Perisporacese, Pyrenomycetes, Hysteriaceae, Discomycetes, and Helvel- lacese. The Basidiomycetes characterized by the possession of basidia are arranged in two groups, based on the character of the basidia: (1) the Protobasidiomycetes, in which the basidia are septate, divided, and (2) the Autobasidiomycetes, in which the basidia are not divided, and bear a definite number of spores. The first of these (Protobasidiomycetes) includes the following dis- tinct groups: (1) the Uredinese, "Rust Fungi," which have horizontally divided basidia, always free, never enclosed : (2) the Auriculariese, having basidia somewhat resembling those of the Uredinese, but which are borne in fruit bodies with open hymenia ; (3) Pileacrese, having horizontal septate basidia in closed receptacles ; and (4) Tremelline?e, having verti- cally divided basidia borne in gymnocarpous receptacles — that is, those in which the hymenium is exposed while the spores are growing. The Autobasidiomycetes are characterized by undivided basidia, bear- 19 ing spores only at the apex. This group is subdivided into liiree sec- tions : (1) Dacyromycetes, which iiichides the lowest of the Treraelloid forms, with club-shaped basidia, nearly approaching the true Hynieno- niycetal type, together with several groups of minor import ; (2) Gastero- mycetes ; and (3) Hymenomycetes, with Phalloidea; placed in the group as a subsection of Gasteromycetes. The above can only be considered as a very brief abstract of the system of classitication proposed by Dr. Brefield, but it will serve to give some idea of the principle on which the system is based, which is sufficient for our present purpose. Those who wish to study the system in detail will find it treated in a comprehensive manner in Dr. Von Tavel's summary as it appears in the Vergleichende Morphologie der Filze^ Jena, 1892. CONIOMYCETES AND HYPHOMYCETES. In the original classification of Fries two of the primary divisions of the sporiferous Fungi were termed, respectively, Goniomycetes and Ily- phomycetes. This arrangement was accepted by Berkeley, the term Coiii- omycetes being applied to all fungi in which the naked spores, appearing like an impalpable dust, were the principal feature of the jjlant, and the term Hyphomycetes to fungi in which the threads or hyphae bearing the spores were the most conspicuous feature. Goniomycetes, as broadly interin-eted by Berkeley and other mycolo- gists of his day, included the Uredineae or " rust fungi," the Ustilagines or " smut fungi," the Sphaeropsidete, and the Melanconieae. This arrange- ment was very unsatisfactory on account of the distinctively different character of the methods of reproduction of the respective groups, and they have since been disassociated and by some authors ranked as dis- tinct orders or families. Others combine Urediuei and Ustilaginei in one group under the name Hypcdermei. Familiar examples of Urediuei are seen in the rust of the Barberry leaf, etc., and of the Ustilaginei in the " smut " of corn and the " bunt " of wheat. Some authors combine the Sphaeropsidese with the closely allied Melan- conieae. M. C. Cooke contends that the Sphmropsidem should be con- sidered apart from the Alelanconiece, on the fundamental basis that the former possess a distinct perithecium, while the latter do not. The Sphmropsidem as recently defined by Cooke are " Fungi possessed of a peritheciwtn, hut vnthout asci, the sporules or stylospores being pro- duced internally at the apex of more or less distinct supporting hyphae or pedicels, termed sporophores." The Sphaeropsideae somewhat resemble the Pyrenomycetejc in external characteristics, but differ from them in the absence of asci and paraphy- ses. Saccardo retains all the species in his Sylloge, but relegates them to an inferior position as imperfect fungi. The group Pyren omycetes, or Sphierlacel, as at first recognized by Fries, included not only the Sphtfiriacei and the Perisporacei, but also 20 the ^^phmropsidei and Melanconiacem. Later, when ascigerous fungi were separated from stylosporous fungi, this group was revised, the as- cigerous species only being retained. As at present limited, the Pyrenomy- cetes are " ascigerous fungi having the fructification enclosed within a perithecium." They constitute a very large group, the described species, according to Cooke's Census of Fangi, numberiog not less than 10,500, or at least 1,000 more than all the recorded species of Hymenomycetes. The plants are microscopic in size, and grow upon vegetable or animal substances. HYPHOMYCETES. With regard to the Hyphomycetes, Cooke takes the ground that in their internal relations to each other, and their external relations to the remain- ing orders, the Hyphomycetes are undoubtedly a well-defined and natural group, and should have place as such in a systematic work. It is a large order, containing nearly 5,000 species, mostly parasitic on dead animals and vegetable matter. The spores, termed conidia, are free, as in Hymen- omycetes. The species are microscopic in size, and the hyphae are strongly developed. They have no hymenium and no true basidia, and are non-sexual in their reproduction. The four primary sections are the Mucedinese, or " white moulds ;" the Dematiese, or "black moulds ;" the Stilbea, with the hyphae or thi'ead-like filaments pallid or brown, and densely cohering, and the Tubercularieae, with the hyphae densely compacted in wart-like pustules of somewhat gelatinous consistency. The divisions called Melanconiese, Sphseropsideee, and Hyphomycetese are not recognized in the Brefield system of classification as distinct groups. Massee and Cooke, with other mycologists, take exception to this omission and its implication, in their discussion of the subject, giving consistent reasons for the retention of these groups in systematic works. PHYCOMYCETES OK PHYSOMYCETES. As originally defined by Berkeley', this group was composed chiefly of the old typical Mucors and their allies, and was then termed Physomy- cetes. In the newer system of classification its original definition has been extended so as to include a number of groups somewhat dissimilar in their habits and characteristics, but '' united under the conservating bond of a dimorphic reproduction," and the name has been changed to Phycomycetes. As at present recognized " the Phycomycetes are charac- terized by a unicellular mycelium, often parasitic on j)lants or animals, sometimes saprophytic, developed in the air or in water. Reproduction sexual or asexual." As thus interpreted, Phycomycetes includes the Mucoracei ; the Peronosporaceae, or " rotting moulds " ; the Cystopi, or " white rusts " ; the Saprolegniaceae, or " fish moulds " ; the Entomo- thoraceiB, or " insect moulds," together with a few minor groups of doubtful natural affinity.

Although some writers apply the terms spore, sporidia, sporophore, sporules, and conidia somewhat indiscriminately to all spore bodies, in order to avoid confusion, it is now recommended l)y the best authorities that certain distinctive limitations should be adhered to in the use of these terms. Saccardo, in defining the terms which he employs, accepts the term spores as applicable exclusively to the naked spores sup- ported on basidia, as found in the Basidiomyceteai. The term sporidia he limits to spores produced or enclosed in an ascus, as in the Ascomycetea?. The term sporules he ajiplies to the spores of imperfect fungi, where they are enclosed in perethecia (microscopic cups or cells), such as the Spharopsidea. The term conidia he uses to designate the spores of imperfect fungi without perethecia or asci, such as the Tlypho- mecetea and the Melanconiea'. This arrangement is in accordance with M. C. Cooke's published views on the subject, except in the case of the spt)re bodies of the Melau- coniea% which he |)refers, for well-defined reasons, to call spoi'ules. In accordance with these limitations, the terms spermatia, stylospores, and clino- sjwres are merged iu sporule. Other terms appropriate to their development are employed to designate the spores of Ure
