 fuscous on disk, fading, glabrous. FLESH membranaceous. GILLS 

 adnate, joined in a collar behind, thin, crowded, distinct, whitish 

 or obsoletely incarnate. STEM filiform, 2-3 cm. long, tough, gla- 

 brous, shining, striatulate under a lens. SPORES 8-10 x 4-6 niicr. 

 (Sacc. and Berk.)." 



Not yet found in the State. I have seen specimens on decayed 

 logs in a neighboring State and it doubtless occurs in Michigan. It 

 has the stature and appearance of M. vulgaris, but the cap is not 

 viscid.

PILETJS 1-2 cm. broad, ovate to convex, viscid when young, gla- 

 brous, striatulate on margin, bright blue when young, becoming 

 .pale and whitish in age or fuscous in the center. GILLS free, 

 narrow, close, white then grayish-white, edge minutely fimbriate. 

 STEM 6-9 cm. long, 1-1.8 mm. thick, slender, hollow, faintly purple 

 when young, becoming whitish or flesh color, flexuous or nearly 

 straight, even, rooting. SPORES globose, smooth, 6-9 micr., white 

 or with a delicate bluish tinge. 



Gregarious, subcaespitose or solitary, on decayed wood, debris, 

 etc. Marquette, Bay View. Not rare in the north. 



A slender, delicately tinted plant, so far found in our northern 

 regions only. It differs from .1/. cyaneobasis in its thinner sub- 

 stance, free gills and brighter colors.
