=Plant= gregarious, 1–2 in. high. =Pileus= 1–1.5 in. broad. =Stem= 1–2 lines thick. Grassy pastures. Jamesville, August. _Peck_, 33d Rep. N.Y. State Bot. A pale form of this species grows on sandy soil, in which the pileus is smoky white, but it becomes grayish-brown in drying. The mycelium binds together a mass of sand, so that when the plant is taken up carefully a little ball of sandy soil adheres to the base of the stem. The stem is sometimes pruinose. The flavor is mild and agreeable. _Peck_, 50th Rep. N.Y. State Bot. Sometimes plentiful about Philadelphia. Edible. Caps tender, slight flavor. =C. comitia´lis= Fr.—belonging to an assembly. =Pileus= about 1½ in. across, fleshy, convex, then plane, obtuse, even, glabrous, rather moist but not hygrophanous, every part colored alike, sooty-umber, almost black. =Flesh= firm, white. =Gills= very slightly decurrent, horizontal, plane, thin, crowded, white. =Stem= 2–3 in. long, 3–4 lines thick, equally attenuated upward from the base, glabrous, sooty, elastic, stuffed. =Spores= elliptical, 7–8×4µ. Damp places among mosses in pine woods, etc. Distinguished by the blackish color of the almost flat pileus, and the very slightly decurrent gills. Somewhat allied to C. clavipes, but firmer, smaller and inodorous. _Massee._ Rather rare. Found in New Jersey among pines; in Pennsylvania in mixed woods. Edible. Good texture and flavor.

CLITOCYBE MONADELPHA. ] ** _Violet or reddish._ =C. cyanophæ´a= Fr. _Gr._—blue. =Pileus= 3–4 in. broad, becoming bluish-dusky-brown, compact, convex then plane, obtuse, smooth. =Stem= 3 in. long, 1 in. thick at the base, attenuated upward, robust, solid, smooth, _becoming azure-blue_ when young, _abruptly white at the apex_. =Gills= deeply decurrent, crowded, violaceous, then becoming pale. New York, Albion. In woods. October. Edible. _Dr. E.L. Cushing._ Specimens sent to me by Dr. Cushing are the first and only ones of the species I have seen. The description is accurate. The spores were cream color. =C. monadel´pha= Morg.—_monas_, single; _adelphos_, a brother. From its cespitose habit. (Plate XXVII.) Densely cespitose. =Pileus= fleshy, convex then depressed, at first glabrous, then scaly, honey color, varying to pallid-brownish or reddish. =Stem= elongated, solid, crooked, twisted, fibrous, tapering at the base, pallid-brownish or flesh color. =Gills= short, decurrent, not crowded, pallid flesh color. =Spores= white, a little irregular, 7.5×5.5µ. On the ground in wet woods, spring to late autumn. =Pileus= 1–3 in. =Stem= 3–7 in. _Morgan._
