Oclirosporae 



F. fla'vida Schaeff. (Pers. ) flamdus, light yellow. Pileus fleshy, 

 thin, broadly convex or nearly plane, glabrous, moist, pale yellow. 

 Flesh whitish or pale yellow, taste bitter. Lamellae moderately close, 

 adnate, pale or yellowish becoming rust-color. Stem equal, often more 

 or less curved, hollow, fibrillose, whitish or pale yellow, with a white 

 mycelium at the base. Spores 8x5/x.. 



Pileus 1-2 in. broad. Stem 1-3 in. long, 1-3 lines thick. 



Decaying wood of various trees. Commonly in wooded or moun- 

 tainous districts. Summer and autumn. 



Our specimens were found on wood of both coniferous and deciduous 

 trees. The plants are sometimes cespitose. The pileus becomes more 

 highly colored in drying. The spores are pale rust-colored approach- 

 ing ochraceous. In Sylloge the spores of this species are described as 

 pale yellowish. Peck, 5oth Rep. N. Y. State Bot. 



Spores broadly elliptical, 6-8x5ft Massee.

F. flavida is a frequent species, gregarious and tufted on decaying 

 vood, either standing, fallen, or as roots in the ground. The texture 

 and substance are good. The slight bitter when raw disappears in 

 cooking. The caps, only, are tender. 



SAPIN'EI. Gills and spores yellowish, etc. 



F. hy'brida Fr. hybrida, a hybrid. Pileus about 2 in. broad, at 



first tawny-cinnamon, then tawny-orange, fleshy, hemispherical with the 

 margin involute, then expanded, obtuse, regular and well formed, even, 

 smooth, moist. Flesh moderately compact, pallid. Stem 2-3 in. long, 

 4-5 lines thick, at first stuffed with a soft pith, then hollow, attemiated 

 (almost conico-attenuated) upward, whitish with adpressed silky-hairy 

 down (becoming tawny when the down is rubbed off) slightly striate, 

 with white hairs at the base, and somewhat mealy at the apex. Veil 

 manifest in the form of an annular zone at the apex of the stem, white 

 or at length colored with the spores. Gills adnate, somewhat crowded, 

 light yellow then tawny, not spotted. Fries. 



Spores elliptical, tawny-ochraceous, 7 8x4-5 /u, Massee; 6x4/1, W. P.
