Nolanea, Fries, Syst. Myc, i. p. 204; Cke., Hdbk., p. 132. 



Nolanea corresponds in structure with Psaihyrella, 

 Psaihyra, Galera, and Mycena. Allied to Leptonia, but dis- 

 tinguished by the margin of the pileus being straight and 

 ]iressed to the stem -when young, and not incurved, and by 

 the usually papillate or slightly umbonate pileus.

In pastures. 



Inodorous. The above description covers the most general 

 form, but the species is variable ; sometimes the pileus is 

 sooty and more or less fibrillose, stem ^imilarly coloured, and 

 gills greyish-pink. The distinctly fibrous stem is always 

 constant, and at once separates this from every other species 

 of Nolanea.
