Porphyrosporse 



PSA'THYRA Fr. 



Gr. friable. 



Veil none or only universal, and 

 floccoso-fibrillose. Stem somewhat 

 cartilaginous, fistulose with a tube, 

 polished, fragile. PileilS conical or bell- 

 shaped, membranaceous , the margin at 

 the first straight and adpressed to the 

 stem. Gills becoming purple or brown- 

 ish. Slender, fragile, hygrophanous. 



Some of the last species of Hypho- 

 loma and Psilocybe are very closely 

 allied to them. The Coprinarii are 

 readily distinguished by the gills being 

 white or ash-color, then black, not 

 dusky-brown nor becoming purple. 



Psathyra corresponds with Mycena, 

 Nolanea, Galera and Psathyrella. All 

 the species grow on the ground or on 

 trunks. Stevenson.
