VATRICOSOID INOCYBE 



Pileus thin, convex becoming nearly plane, slightly viscid when 

 moist, obtuse or subumbonate, fibrillose on the margin from the 

 abundant whitish webby veil, whitish, often reddish in the center, 

 flesh whitish, odor like that of radishes; lamellae close, broadly 

 sinuate, adnate with a decurrent tooth, whitish becoming brownish 

 ferruginous, white crenulate on the edge; stem equal, flexuous

Damp ground under willows. Ulster co. September. 



This species is closely allied to Inocybe v a t r i c o s a Fr. 

 to which it was referred in New York State Museum Report 41, 

 page 67, but from which it is here separated because of its well 

 developed webby veil, its radishlike odor, its adnate lamellae, its 

 silky fibrillose stem and its larger spores.

NEW YORK SPECIES OF HEBELOMA 



Hebeloma Fr. 



Veil ])artial, fibrillose or obsolete; stem fleshy fibrous, somewhat 

 mealy at the apex ; margin of the pileus at first incurved, the cuticle 

 continuous, glabrous, subviscid ; lamellae sinuate, adnexed, usually 

 whitish on the edge ; spores subargillaceous. Syllogc 5 1791 



This genus formerly included the species now referred to Inocybe. 

 It differs from it specially in its partial veil and in its continuous, 

 subviscid and glabrous cuticle. Some of the species have a peculiar 

 radishlike odor. The spores in all our species are even. As in the
