Suh.-Gen. 8. Mycexa. Fr. S. M. i. p. 140. 



Pileus more or less membranaceous, generally striate, with the 

 margin always straight, and at first pressed to the stem, never 

 involute, expanded, campanulate, and generally umbonate (not 

 depressed, as in Omphalia) ; stem externally cartilaginous, tubu- 

 lar, not stufied when young, confluent with the hymenophore, 

 but heterogeneous from it ; gills never decurrent, though some 

 species have a broad sinus near the stem. — (PZ. II., Jig. 8.) 



Hab. Mostly epiphytal. 



Most of the species are small, beautiful, and inodorous, but some which 

 have a strong alkaline odour are probably poisonous ; none are known to be 

 edible. They appear after rain in summer and autumn.
