116 FUNGUS-FLORA. 



Small, fragile, inodorous, juiceless, not caespilose. Stern 

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

 often curved and ascending, even, glabrous, livid becoming 

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

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

 purple, pale when dry. Gills aduate, with a decurrent tooth y 

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

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

 ffuinolenta in size and in the juiceless stem. Allied to 

 M. metata, which differs in growing on ihe ground, 

 pileus silky-atomate when dry, margin of gills not dis- 

 coloured. (Fries.)

 Hdbk., p. 369 ; Cke., Illustr., pi. 959A.
