 N. Y. State Mus. Rep't 42, p.i8 



Pileus thin, convex or nearly plane, umbilicate, 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 ix.

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

 and its broader paler lamellae.
