70 THE AGARICACEAE OF MICHIGAN 



of M. varicosus seems to secrete a dark-red juice, but it is quite dif- 

 ferent from Mycena haematopoda. 



**gtem, at least when dry, everywhere pruinose-velvety.

Gillet, Champignons de France, No. 441. 



Patouillard, Tab. Analyt., No. 577. 



Patouillard, Tab. Analyt., No. 125 (as M. calopus). 



PILEUS 1-2.5 cm. broad, bemispberic-campanulate, then plane, 

 obtuse or subumbonate, pruinate, dark rose-madder, darker on disk, 

 rugulose when dry, margin at first incurved. FLESH white, thin. 

 GILLS narrowly adnate, seceding, subdistant, ventricose, rather 

 broad, white or tinged ochraceus, scarcely intervenose, edge very 

 entire. STEM 4-5 cm. long, 1-1.5 mm. thick, equal, horny, stuffed 

 then hollow, dark reddish-brown to blackish below, tough, flexuous. 

 pallid at apex, minutely pruinose, with an enlarged mycelioid base. 

 SPORES elliptical-lanceolate, curved-apiculate, 7-9x3.-3.5 micr. 

 CYSTIDIA none. ODOR and TASTE mild. 



On decaying leaves and twigs, on the ground in frondose woods, 

 especially of beech. Ann Arbor. July-September. Rare. 



This approaches M. glabellas and M. calopus Fr. ; from the former 

 it is separated by its different spores and gills, from the latter by 

 its pruinose stem. Some specimens seem to have an entirely glab- 

 rous stem, thus being close to M. calopus. The color of pileus does 

 not change. The pileus is not sulcate as in M. siccus. It departs 

 from the descriptions of European authors in the spore-size and 

 the less distant gills.

''PILEU/S 1.5-3.5 cm. broad convex or expanded, glabrous, gray-

 branaceus. GILLS very narrow, crowded, whitish or gray. STEM
