=C. fumo´sa= Pers.—_fumus_, smoke. =Pileus= 1–3 in. across, fleshy, margin thin; convex, often gibbous when young, regular or wavy, even, pellicle not separable, glabrous, sooty-brown, soon livid or gray when dry. =Gills= adnate in regular forms, but often decurrent when the pileus is irregular, crowded, distinct, grayish-white from the first. =Stem= 2–3 in. long, 3–6 lines thick, almost equal, often twisted or curved, glabrous, dingy-white, apex mealy, solid, fibrous. =Spores= subglobose, 5–6µ diam. In woods. Autumn. Gregarious, somewhat cespitose, tough, rather cartilaginous. Pileus truly obtuse, never streaked, often regular. Smell none. _Fries._ Var. _po´lius_. Densely and connately cespitose. =Pileus= convex, then plane, obtuse, smooth, gray. =Stem= flexuous, smooth. =Gills= crowded, whitish. Edible. _Cooke_, 1891. Var. polius found growing in large quantities in Boston navy yard in stone barn. Determined by Professor Peck. A fair edible. _R.K. Macadam._ This woods-growing Clitocybe has been many times found by me in a hot-house in Haddonfield, N.J. Professor Peck confirmed my identification. Either its spores or mycelium had evidently been carried thither in the wood-earth used by florists. The hot-house crops appeared in March, and continued until June. Several of the plants showed an effort to comply with some condition unusual to them, by producing gills upon the upper side of the pileus. Those below were venose and crisped. This wild species had thus been brought into cultivation. The cultivated plants were much more tender than the wild. Both are excellent. =C. connex´a= Pk.—_connexus_, joined. From its relation to Tricholoma. =Pileus= thin, convex or expanded, subumbonate, clothed with a minute appressed silkiness, white, the margin sometimes faintly tinged with blue. =Gills= crowded, narrow, white inclining to yellowish. =Stem= equal or tapering downward, solid, whitish. =Plant= 2–3 in. high. =Pileus= 2–3 in. broad. =Stem= 2 lines thick. Ground in woods. Croghan. September. The gills sometimes terminate rather abruptly and are not strongly decurrent, hence it might easily be mistaken for a Tricholoma. The margin of the pileus is sometimes marked with slight ridges as in Ag. laterarius. The odor is weak but aromatic and agreeable. _Peck_, 26th Rep. N.Y. State Bot. Found in plenty in oak woods near Philadelphia, and in West Virginia; a few specimens in southern New Jersey. Autumn. Edible, and quite equal to most of the Clitocybes. =C. tumulo´sa= Kalchbr.—_tumulus_, a mound. Cespitose. =Pileus= 1–2 in. across, disk fleshy, margin thin; conico-convex then expanded, obtusely umbonate or obtuse, even, glabrous, brownish-umber, becoming pale, margin drooping. =Gills= more or less decurrent or slightly emarginate, crowded narrow, white, then grayish. =Stem= 3–5 in. long, unequal, usually thicker below, minutely downy, pallid, solid.
