PILEUS 2-5 cm. broad, convex, obtuse, grayish-fcroww (moist), 

 hygrophanous, edge incurved, minutely tomentose-silky. FLESH 

 thin, white, fragile. GILLS adnexed, broad, subdistant, liexuose, 

 pale flesh color. STEM 4-7 cm. long, 4-8 mm. thick, equal or sub- 

 equal, stuffed soon hollow, pruinose at apex, slightly fibrillose, 

 whitish. SPOKES angular, ovate, angles not definite except the 

 very marked angle at the oblique prominent apiculus, S-10 micr. 

 long (with apiculus), <i-7 micr. wide; flesh color. ODOR strongly 

 acid or alkaline. 



Solitary. On mosses, in a sphagnum bog. Ann Arbor. Septem- 

 ber. Rare. 



Differs from the type in the obtuse to subumbonate cap, less 

 slender habit and by not being entirely glabrous. The European 

 plan! is said to have an umbilicate or depressed pileus and slender 

 stem.

PILEUS 3-8 cm. broad, campanula te then plane, subumbonate, 

 grayish-brown (moist), fading, paler to creamy-buff or whitish

 striatulate (moist) elsewhere even, glabrous, silky-shining (dry), 

 surface scarcely differentiated, margin at length splitting or re- 

 curved. FLESH thin, concolor, scissile. GILLS narrow, narrow- 

 ed to a point in front, moderately close, thin, adnexed becoming 

 emarginate, white at first, maturing slowly, at length pale flesh 

 color, edge rather eroded. "STEM long and somewhat slender, 5-10 

 ••in. long, 5-10 nun. thick, pure shining white, variously curved, ob- 

 scurely undulate, innately silky-striatulate but glabrous, equal or
