PILEUS 8-10 mm. broad, at first ovate or conical, then broadly 

 convex, squamulose, finely striate to the disk, white becoming gray- 

 ish-brown, membranaceous, margin generally splitting and becom- 

 ing recurved. GILLS narrow, crowded, reaching the stipe, brown 

 with a ferruginous tint. STEM 16-20 mm. long, slender, glabrous, 

 hollow, slightly thickened at the base, white. SPORES 7.5x5 

 micr., elliptical, brown. On decaying stems of cabbage and other 

 vegetable debris. 



Occasional upon vegetable debris of various kinds. Palmyra, 

 Ann Arbor. We have found this fungus upon corn stalks, weed 

 stalks and dead grass. 



It seems very probable that this is the plant figured and de- 

 scribed as ('. tigrinellus, Boudier, Table 139, and C. friesii Quel.
