NOLANEA. 257 



first straight and pressed to the stem ; gills adnexed or free, 

 never decurrent ; stem central, cartilaginous, hollow, the 

 cavity sometimes filled with a floccose pith; spores with 

 a pink or salmon tinge. 



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



Nolanea corresponds in structure with Psathyrella, 

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

 tinguished by the margin of the pileus being straight and 

 pressed to the stem when young, and not incurved, and by 

 the usually papillate or slightly umbonate pileus.

Pileus membranaceous, conical, then more or less ex- 

 panded, smooth, hygrophanous, f-1 in. high, about the same 

 across, livid bistre, paler when dry and silky, shining; 

 gills rather crowded, almost free, salmon-colour, margin

In pastures. 



Inodorous. The above description covers the most general 

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

 booty and more or less fibrillose, stem bimilarly coloured, and 

 gills greyish-pink. The distinctly fibrous stem is always 

 constant, and at once separates this from every other species 

 of Nolanea.
