hollow, minutely squamulose or furfuraceous, easily splitting, 

 often curved, whitish ; spores subglobose, .00016 to .000^ in. in 

 diameter.

 thick. 



Prostrate trunks of hemlock in woods. Adirondack moun- 

 tains. August. 



The dark colored umbilicus is a noticeable feature. Tfcie plant 

 has not been found since its discovery in 1869. The species is 

 evidently rare. It is apparently closely related to Collybia 

 abundans, from which it is distinguished by its more decided 

 darker umbilicus and squamulose pileus.

Pileus convex, umbilicate, glabrous, olive-green ; lamellae sub- 

 distant, arcuate-decurrent, pale-yelloio ; stem equal, short, glab- 

 rous, hollow, colored like the pileus; spores subglobose or 

 broadly elliptical, .00025 to .00028 in. long, about .0002 in. broad. 



Pileus about 1 in. broad ; stem about 1 in. long, 1 line thick.
