Psathyra. 



Subge7ins XXXIII. PSATHYRA (i^a0J5pJr, friable). Veil 

 none or onlv universal, and floccoso-fibrillose. Stem somewhat 



cartilaginous, fistulose with a tube, 

 polished, fragile. Pileus conical or 

 campanulate, 7nejnbrajiaceous, the 

 margiji at the first straight and ad- 

 pressed to the stem. Gills becoming 

 purple or fuscous. Slender, fragile, 

 hygrophanoiis. [The series of tough 

 species does not exist among the 

 Psathyrae ; the analogous farms will 

 be found among the tough species 

 of Psilocybe.] Sojne of the last spe- 

 cies of Hypholoma and Psilocybe are 

 very closely allied to them. The 

 Coprinarii are readily distinguished 

 by the gills being white or cinereous 

 then black, not fuscous nor becoming 

 purple. Fr. Hym. Eur. p. 304.

 Psathyrella. All the species grow on the ground or on trunks,
