PSATHYRA. 361 



Stem fistulose, 1-1 in. long, 1-2 lines thick, equal, 

 villous, apex rather powdery, silvery. Pileus submem- 

 branaceous, ovate then campanulate, i in. high and broad, 

 1 in. broad when expanded, not striate, but densely covered 

 for a long time with white feathery scales, at length naked, 

 changing from livid to white, or in the young stage brownish- 

 bay. Gills adnexed, crowded, ventricose, broad, livid then 

 blackish-brown. (Fries.)

 tose then smooth, margin striate ; gills adnexed, ventricose, 

 rather broad, white then brownish-black ; stem about 2 in.

 rather wavy ; spores elliptical, 10 x 6 //,.

On the ground and on fragments of twigs in woods. 



Often subcaespitose, fragile, distinguished from Psathyra 

 pennata by the striate margin of the pileus. 



From the habit was once considered as a Coprinus, but 

 evidently a Psathyra, allied to P. pennata, from which it 

 differs more especially in the loose floccose covering of the 

 pileus (veil) being more tomentose, and which densely 

 clothes the young fungus, the colour also differs in being 

 ochraceous clay-colour. When adult the pileus is glabrous 

 and pale. Gills livid, then fuscous. The rest as in P. pen- 

 natus. (Fries.) 



Psathyra noli-tangere. Fr. 



Pileus - in. across, membranaceous, campanulate then 

 expanded, everywhere striate, hygrophanous, squamulose 

 about the margin, pale umber, becoming pale when dry ; 

 gills adnate, broad, pale brown ; stem about 1| in. long, 

 1 line or more thick, very fragile, nearly naked, apex even ; 

 spores elliptical, 12 x 5 p..
