Small, fragile, inodorous, juioeless, not caespitoso. Stem 

 fistulose, 1-2 in. long, not exceeding 1 line thick, equal, 

 often curved and ascending, even, glabrous, livid becoming 

 pale. Pileus membranaceous, campanulate, obtuse, 1 in. across, 

 glabrous, hygropbanons, grey, livid-reddish or brownish- 

 parple, pale when dry. Gills aduate, with a decurrent tooth, 

 distant, distinct, not ventricose, whitish then grey, margin 

 purple-brown, not evidently toothed. Differs from M. san-
