Stem solid, but pithy; white,, generally crooked, one and a half inch high, 
not quite so thick as a goose quill. 
(Shaded Agaric. E.) Ag. parasiticus. Bull. Bedrock plantation, Edg-

Bat sch 109. 
Gills fixed, pale dead brown, narrow, not crowded, four in a set. 
Pileus pale cool uniform brown, rather glossy, flat, the edge turned down 
and very thin: one and a half to two inches over. Flesh hardly any. 
Stem solid, whitish brown, straight, one and a half to two inches high, 
quarter of an inch diameter, thickest adjoining to the pileus. 
The whole plant has a tough leathery texture. The name given by Batsch 
has likewise been applied by Bolton and Bulliard to Ag. alneus and 
Ag. hetuKnus, but improperly. All the specimens we found had their stems 
perfectly flat, and the gills readily separating from the top of the stem, 
but not without taking with them its outer skin.

The conical pointed boss in the centre of the pileus is the most striking 
feature in this plant.
