rigid; not fusiformly rooting, distinguished from allies by 

 the tumid, inflated, hairy base of the stem. (Fries.) 



Mycena dissiliens. Pr. 



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

 branaceous, aoorn-shaped then conico-oampanulate, not be- 

 coming flattened, but the margin becomes upturned, sulcate 

 to the middle, dry, greyish-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 

 short, 2 in. long, 1-2 lines thick, attenuated from the strigose 

 base, glabrous or slightly pruinose, juiceless, finely striate 

 under a lens, grey, splitting into flaps that curve outwards 

 when compressed or bent.

On trunks, subcaespitose, or on the ground among fallen 

 branches, &c. 



Very fragile, smell unpleasant. In shady places the pileus 

 is generally covered with a spidery silkiness. Distinguished 

 by the greyish-brown sulcate pileus, and by the split 

 portions of the stem curling outwards. 



Mycena; plicosa. Fr. 



Fragile, pileus very thin, campanulate then expanded, 

 margin sulcate, greyish-brown when moist, opaque and buff 

 when dry; gills distant, thick, broadest in front, adnate^ 

 connected by veins, grey; stem smooth, even, shining, 

 hollow, often rather flexuous, 1^-2 in. high, slender, equal,

Among grass, &o. 



Stem rather rigid (not soft as in M. metata), rather fragile,
