Three forms were found growing together. The first and 

 most abundant has the mature pileus glabrous or slightly silky 

 on the margin only; the second has the grayish or reddish gray 

 pileus adorned with appressed fioccose scales ; the third differs 

 from the second only in the dark chestnut color of the pileus.

 partly in fragments to the margin of the pileus and partly as an 

 annulus to the stem. The cavity of the stem is very small. A

 belongs to the section Indusiati. The variety differs from the 

 type especially in its strongly developed veil.

 pores. It grows on hemlock bark and forms small patches rarely 

 more than one inch in diameter. Alcove. September. Shear.

 ruptures in a stellate manner. Menands. November.
