tions, but I have been able to distinguish only M. corticola within 

 our area. 



845. Mycena setosa (Sow.) Fr. 



Hymen. Europ., 1874. 

 Illustration: Cooke, 111., PL 193. 



PILEUS 1-2 mm. broad, minute, very thin, hemispherical, obtuse, 

 glabrous, becoming fuscous. GILLS distant, narrow, white. 

 STEM delicately filiform, 10-12 mm. long, inserted, capillary, every- 

 where shaggy with distant spreading hairs. 



On fallen leaves and pine needles, in woods of white pine and 

 beech. New Richmond. September. Rare. 



Section VI. Adonidae. Stem dry and usually growing from 

 the ground. Gills of one color, neither darker on edge, nor becom- 

 ing ashy nor fuscous. 



The plants in this section are usually brightly colored or white, 

 not with ashy or fuscous shades on cap and gills. Those of the 

 following sections often have white gills at first but become tinged 

 with cinereous or fuscous color, although this character is in some 

 cases scarcely determinable in fresh specimens.
