Agaricaceae 



ciitocybe. C. viles'cens Pk. vilesco, of little value. Pileus convex, then plane 

 or depressed, often irregular, glabrous, slightly pruinose on the in- 

 volute margin, brown or grayish-brown, becoming paler with age, often 

 concentrically rivulose. Gills close, adnate or decurrent, cinereous, 

 sometimes tinged with dingy-yellow. Stem short, solid, sometimes 

 compressed, grayish-brown, with a whitish tomentum at the base. 

 Spores subglobose or broadly elliptical, 5-6. 5/x; flesh whitish-gray, 

 odor slight. 



Plant gregarious, 1-2 in. high. PiletlS 1-1.5 in. broad. Stem 

 12 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 iK 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, 7-8x4^. 



Damp places among mosses in pine woods, etc. Distinguished by 

 the blackish color of the almost flat pileus, and the very slightly decur- 

 rent gills. Somewhat allied to C. clavipes, but firmer, smaller and in- 

 odorous. Massee. 



Rather rare. Found in New Jersey among pines; in Pennsylvania 

 in mixed woods. 



Edible. Good texture and flavor. 



** Violet or reddish. 



C. cyanophse'a Fr. Gr. blue. Pileus 3-4 in. broad, becoming 

 bluish-dusky-brown, compact, convex then plane, obtuse, smooth.
