=M. allia´ceus= Fr.—_allium_, garlic. =Pileus= 1–1½ in. broad, whitish inclining to fuscous, often milk-white when young, somewhat membranaceous, campanulate then expanded, somewhat umbonate, even, at length striate and sulcate, smooth, dry. =Stem= as much as 8 in. long, _horny_, rigid, fistulose, attenuated upward, _pruinato-velvety, blackish_, rooted at the base where it is somewhat incurved and naked. =Gills= adnexed in the form of a ring, then _free_, slightly ventricose, arid, slightly distant, fuscous-whitish, crisped when dry. Odor strong, of garlic, persistent. _There is nothing of a reddish tinge in the whole plant._ The stem is not tomentose at the base as in the Tergini. _Fries._ Among leaves and on rotten wood. Frequent. August to October. _Stevenson._ =Spores= 14–16×8µ. _Massee_. North Carolina, _Schweinitz_, _Curtis_; Pennsylvania, _Schweinitz_; Minnesota, _Johnson_; Novia Scotia, _Somers_. Edible. Bull. Boston Myc. Club. [Illustration] =HELIOMYCES= Lev. _Helios_, the sun; _myces_, a fungus. =Pileus= membranaceous, between leathery and gelatinous, radiately sulcate. =Gills= equal, edge acute. =Stem= somewhat woody, cylindrical, central. Allied to Marasmius, but differing in its sub-gelatinous substance. None reported edible. ---------- =LENTI´NUS= Fr. _Lentus_, tough or pliant. (Plate LII.) [Illustration: SECTION OF LENTINUS.] =Pileus= fleshy-coriaceous, pliant, tough and hard when old, persistent. =Gills= becoming dry, tough, simple, unequal, thin, margin acute, _toothed_, more or less decurrent. =Stem= when present central, excentric or lateral, hard and firm, continuous with the flesh of the pileus. Growing on wood. =Spores= somewhat round, even, white. Distinguished from other coriaceous genera by its serrated and torn gills. “The genera Lentinus and Lenzites are found in every region of the world; their principal center, however, is in hot countries, where they attain a splendid development. On the contrary, toward the north they rapidly decrease in number.” Fungi. _Cooke and Berkeley._ In habitat and mode of growth Lentinus closely resembles Pleurotus, and parallel genera with colored spores. When young the species are inviting, and when well cooked are meal-giving. They are not delicacies, but substantials. They dry well. Grated they make soups, and give their pleasant flavor to any dish. ANALYSIS OF TRIBES. MESOPODES (_mesos_, middle; _pous_, a foot). Page 229. Stem distinct. PLEUROTI (_pleura_, a side; _ous_, an ear). Stem lateral or absent. None known to be edible I.—MESO´PODES (center-stemmed). =L. Lecom´tei= Fr. =Pileus= coriaceous, funnel-shaped, regularly reflexed, hairy, tawny. =Gills= crowded, pallid. =Stem= short, hairy, tawny. Common to the states.
