FUNGI 47 



mostly whitish or pallid at and near the base, blackish toward and on 

 the margin. They are probably white or whitish when fresh and 

 assume the blackish color with age or in drying. Though inhabiting 

 mosses, the species may be distinguished from C. muscigenus by the 

 zoneless and differently colored pileus, by the entire absence of a dis- 

 tinct stem, and by the smaller spores. In one specimen the pileus is 

 slightly fibrillose.

Omphalia semivestipes Peck.t 



Orca (Trelease, 522, 524). 



These specimens have the stems longer than they are in the type, 

 but they are evidently the same species.

Omphalia sphagnophila Peck, sp. nov.f 



Pileus at first narrowly obconic and centrally depressed, becoming 

 tubiform or subinfundibuliform, thin, glabrous, whitish or pale yellow ; 

 lamella? moderately broad, distant, very decurrent, yellow, the inter- 

 spaces sometimes venose ; stem short, solid or stuffed, pruinose or 

 minutely downy, whitish with a white mycelium at the base ; spores 

 broadly elliptic, 6-7 fi long, 4-5 p. broad. 



Pileus 1-2 cm. broad; stem 1-2 cm. long, 2-4 mm. thick. 



Port Clarence (Trelease, 558). Growing among and attached to 

 the stems and branches of Sphagnum. 



This species is closely related to O. umbcllifera, of which it may 

 possibly be a variety, but it is easily separated by its peculiar shape, 

 especially when young, and by its more narrow and much more decur- 

 rent lamellae.
