rigid; not fnsiformly rooting, distinguished from allies by

Mycena dissiliens. Fr. 



Strong-scented. Pilens about 1 in. across, almost mem- 

 branaceous, acorn-shaped then conico-campanulate, not be- 

 coming flattened, but the margin becomes upturned, sulcate 

 to the middle, dr}-, greyisli-fuscous, becoming whitish at 

 the margin ; gills rounded behind, seceding and becoming 

 almost free, broadest in front, apex very obtuse, soft, watery, 

 whitish base, tinged grey, the shorter ones crisped ; stem

Among grass, &c.
