 * Gills Iroad, lax, usually more or less distant. 



CoUybia coUina. Scop,

In grassy places. 



Usually gregarious. With the habit of a Mycena, but the 

 margin incurved at first. Somewhat resembling a small 

 form of C. radicata, but differing in the abrupt, and not 

 rooting base of stem. 



CoUybia thelephora. Cke. & Mass. 



Pileus f— 1|- in. across, flesh rather thin ; campanulate, lax, 

 with a small but acute papillate umbo, margin incurved at 

 :first, then expanded and wavy, glabrous, slightly striate, 

 pale dingy ocliraceous, the disc darker ; gills adnate, 1^ line 

 broad, narrower in front, thin, rather crowded, whitish ;
