CORTINARIUS. 87 



C. (Inoloma) pulchrifolius. Pk. 



Pileus, convex, expanded, silky fibrillos, whitish or red- 

 dish gray, the margin often white by the veil. 



Gills, emarginate, distant, bright purple, and last rusty 

 from the spores. 



Stem, solid, bulbous, fibrillose, white, often tinged with 

 violet, violet within. 



Found specimens on Koch's Island. Not common in the Valley. 



Tribe IV. Dermocybe. 



Pileus thinly and equally fleshy, at first silky with somewhat 

 innate villous down, but becoming smooth when old, dry and 

 not hygrophanous. Flesh watery when moist or colored. 

 Stem equal or attenuated, externally more rigid, elastic or 

 brittle, internally stuffed or hollow. Veil single, fibrillose, 

 forming a zone in C. caninus. A natural group easily distin- 

 guished from Inolomata by the thinness and substance of the 

 pileus and by the stem ; and from the following tribes by 

 the pileus not being moist or hygrophanous, and by its short 

 floccose or atomate covering, its brighter color. 



The species of this tribe are very changeable, and not 

 easily defined on account of the changeable color of the gills. 

 It comprehends two primary types ; first of C. anomalus with 

 the flesh of the pileus white, and secondly that of C. cinna-- 

 momeus with the flesh scissle and colored. — Stevenson' s British
