Pileus thin, convex or nearly plane, umhilicate, glabrous, hygro- 

 phanous, grayish brown and striate on the margin when moist, paler 

 when dry, flesh concolorous, odor and taste farinaceous ; lamellae 

 broad, close, adnate, whitish or pale cinereous; stem equal, glabrous, 

 hollow, colored like the pileus ; spores ellipsoid, 5-6 x 3-4 fi.

 which it may be separated by the umhilicate pileus, its striate margin 

 and its broader paler lamellae.
