Crepidotus mollis Gray Crepidotus 



Cap 2-8 cm. wide, usually shelving, but sometimes with a short, lateral hairy 

 stem, pale or grayish, smooth, more or less ovoid or kidney-shaped, often lobed ; 

 gills decurrent, brown, narrow and crowded ; spores dark-brown, ellipsoid, 8- 

 9 X 5-6/x. The name refers to the soft texture. 



On decaying wood, stimmer and autumn; probably edible, but not tested. 



PAXILLUS 



Distinguished among ocher-spored forms by the readiness with which the gills 

 are separated from the cap. The gills are decurrent and often fork and unite, so that 



tliey are more or less pore- 

 like. Related to Go m- 

 p h i d i u s among the 

 black-spored forms. Our 

 species grow on the ground 

 and are edible. The name 

 has no evident application. 



Paxillus involutus

 yellowish, tawny or rust- 

 colored, smooth, sticky 

 when moist, convex to 

 plane, finally depressed, 

 the margin downy and in- 

 rolled, more or less striate 

 and furrowed when un- 

 rolled ; stem 5-8 cm. by 

 1-3 cm., pale yellow or 

 rust-colored, smooth, solid,
