Apparently intermediate between l/. prolifera and I/, inclinatq, 

 concerning whose microscopic characters little is known. h is 

 allied to the former by its broad and dark umbo' and t<> the latter 

 by the character of the stem, the cernuous pileus which is a1 flrsl 

 much incurved and the stronglj fuscescenl colors <>r cap ;in>l stem. 

 The narrow gills are still more aarrowed and broadlj Binuate 

 behind. The pileus often undulates from umbo to margin, and 

 remains obtusely conic-campanulate. No tendency of the stem 

 io proliferate was observed. Ii is very distincl from i/. galericu 

 lata. The figure <>r Gillel does aol appear to agree ;n ;ill with the 

 description of Fries.

PILEUS 1.5-4 cm. broad, firm, campanulate, broadly umbonate, 

 gibbous, dark brown, dark umber <><■ blackish-fuscous, ruguh 

 margin at first straight. FLESH concolor or paler. GILLS ad 

 nexed by an abruptly much oarrower portion, elsewhere rather 

 broad, ventricose, subdistant, thickish, pallid then tinged brownish. 

 STEM short, 2-3 era. Long, 2-4.5 mm. thick, equal, floccose-flbrilh 

 glabrescent, stuffed then hollow, rigid, toughish, often twisted,
