spores elliptical, .(»(»(>24: to .00028 in. long, .00012 to .00016 broad. 

 Pileus 4 to 8 lines broad ; stem about 1 in. long, scarcely 1 line 

 thick. 



Much decayed wood of coniferous trees. Very common. May 

 to November. 



This ])retty little species occui-s everj'U'liere in woods and 

 shaded places where there are ])rostiate, much decayed trunks of 

 hemlock, spruce and pine. It makes its appearance as soon as 

 the weather is moderately warm in spring, and successive crops 

 develop till all growth is stopped by the return of the cold 

 weather of winter. Rarely it grows on ground well filled with 

 decaying vegetable matter. It usually grows in large flocks or 

 dense clusters but sometimes is more scattered. It is the most 

 frequent and most abundant of our species of Omphalia and is 

 easily recognized by its yellowish-red pileus, dark-brown stem and 

 the little ball or tuft of tawny-colored coarse hairs at the base of 

 the stem. The pileus varies some in the intensity of its color but 

 all the hues of the moist plant appear to be mixtures of yellow and 

 dull red in different proportions. In the dry plant, the yellow 

 predominates. The mycelium of this species is regarded as 

 destructive to the wood of coniferous trees.

 Button-like Omphalia. 



(Report 34, p. 03.) 



Pileus thin, convex, deeply umblicate, glabrous, hygrophanous, 

 dull orange and striatulate when moist, paler when dry ; lamellae 

 rather close, arcuate strongly decurrent, white, the interspaces 

 venose; stem equal, glabrous, hollow, colored nearly like the 

 pileus; spores elliptical, .0003 in. long, .0o02 broad. 



Pileus 6 to 10 lines broad ; stem 1 to 2 in. long, scarcely 1 line 

 thick. 



Burnt, mossy ground. Lewis and Sullivan counties. September. 



It is closely related to Omphalia Fibula, which it resembles in 

 color, but from which it may easily be distinguished by its much 

 larger size, more robust habit and venose interspaces. Its spores 

 also are larger than in that species.
