Asheville, on or around well decayed wood in mountain woods; rather 



rare. Beardslee. 

 Middle district (Schw.), woods. Curtis. 



2. Collybia butyracea Bull. 



Plates 5, 6, and 23 



Cap up to 6 cm. wide, convex, sometimes umbonate, smooth, 

 shining, color pinkish-buff, darkest in center. Flesh 2. 5 mm. thick 

 at stem, very thin towards margin, soft. 



Gills deeply depressed and angled at stem, nearly free, close, none 

 forked, many short, up to 5.5 mm. wide near stem; white, margin 

 strongly eroded. 



Stem up to 6 cm. long, usually flattened and channelled, up to 5 mm. 

 thick at cap, enlarging downward, smooth except near base which is 

 incrassated with white mycelium, more or less obviously marked all 

 over with longitudinal striations, color of cap, darkest below, flesh 

 firm, elastic, fibro-cartilaginous, quite hollow. 



Spores (of No. 1902) not white, exactly light buff of Ridgway, 

 subpip-shaped, smooth, 3-3.7 x 5-6 [i.. 



On earth in woods, rare. There is a greasy look to the cap, which 

 gives the plant its name. 



I cannot find any quality that will hold good between this and all 

 the forms of C. dryophila. In Chapel Hill forms occur with greasy- 

 looking caps and slender equal stems, and Beardslee 's photo, of C. 

 dryophila on earth shows the stem enlarged below just as in C. butyra- 

 cea. Also the slender stemmed plants of C. dryophila often show the 

 stem distinctly lined when a lens is used. The spores of the two 

 species as we have distinguished them here are identical.

 2431. Under shrubs in Mr. Woollen's yard, July 25, 1916. Spores elliptic,
