Lamelle attenuate-attached or nearly free, distant, whitish. 
Growing on dead leaves in woods, common throughout the summer. 
Pileus 4-#ths of an inch in diameter, the stipe 2-3 in. long. Thisis avery 
elegant species, flourishing abundantly, and growing quite rank in our 
rich woods, I find specimens sometimes with a pinkish tint.

On dead sticks in woods. Pileus 2 lines broad, stipe 1 in. long. 
The stipe is attached by a minute bulb. The species is remarkable

Growing among leaves and on the ground in wouds. Stipe 1} in. 
in length, black but wholly covered over with a white meal which may 
be easily rubbed off. It is closely related to M. alliaceus, Jacq., but is 
inodorous. I am indebted to Mr. Stevenson for the copy of the 
original description. ‘ 
EH. Pileus soon umbilicate.
