Omphalia Epichysium Pers. 

 Overspreading Omphalia. 



(Hym. Europ. p. 158. Syl. Fung. vol. V, p. 314) 



Pileus membranous, soft, nearly plane, umbilicate, hygro- 

 phanous, sooty-gray and striate when moist, paler when dry and 

 silky or flocculose; lamellae narrow, subdistant, slightly decur- 

 rent, whitish or cinereous ; stem equal, somewhat hollow, 

 glabrous, cinereous ; spores elliptical, .0u03 in. long, .00016 broad. 



Pileus 6 to 12 lines broad; stem about I inch long, I line thick. 



Decaying wood and dead trunks of trees. Adirondack moun- 

 tains. August. 



Omphalia Gerardiana Pk. 



Gerard's Omphalia. 



(Agaritus (Jerardianus. Rep. 26, p. 54 ) 



Pileus thin, nearly plane or soon funnel-form, generally umbil- 

 icate, fragile, dotted with minute blackish points, hygrophanous, 

 brown or grayish-brown and striatulate when moist, paler when 

 dry ; lamellge narrow, subdistant, decurrent, sometimes forked, 

 whitish or cinereous ; stem long or short, glabrous, stuffed or 

 hollow, colored like the pileus ; spores oblong or ovate-oblong, 

 .0003 to .00045 in. long, about .00016 broad. 



Pileus 8 to 12 lines broad; stem 1 to 2.5 in. long, .5 to 1 

 line thick. 



Growing in Sphagnum. Rensselaer, Ulster and Seneca 

 counties. June. 



This fungus was formerly referred to the subgenus Clitocybe, 

 but later observations indicate a closer relationship to Omphalia. 

 It is closely related to such species of Omphalia as 0. affricata, 

 O. telmatioia, 0. sphagnicola and O. philonotis. From all these it 

 differs in the peculiar adornment of the pileus. 



Omphalia montana Pk. 



Mountain Omphalia. 



(Report 27, p. 94.) 



Pileus thin, umbilicate, glabrous, blackish-brown ; lamellae dis- 

 tant, decurrent, whitish, darker on the edge, stem equal, glabrous, 

 colored like the pileus ; spores broadly elliptical, about .0003 in. 

 long.
