species; it is marked by the resupinate-reflexed habit of most 

 fructifications; only rarely is a fructification attached by its 

 vertex. The dried specimens are externally minutely fibrillose 

 under a lens but do not show hairs in microscopic preparations. 

 When the fructifications are moistened the hymenium shows 

 two or three minute wrinkles radiating from an eccentric point. 



Specimens examined:

 respectively. 



Fructifications scattered, rarely in clusters of two or three, 

 sessile, cup-shaped, somewhat globose, externally mineral gray 

 and obscurely tomentose, the margin incurved; hymenium 

 concave, even, fuscous; basidia clavate, 20-25 x 4-6 ju, having 

 2-4 sterigmata which become finely attenuated ; spores colorless, 

 angular, 4^-6 x 4| m- 



Fructifications | mm. high, |-1 mm. broad. 



On bark of Juniperus virginiana. South Carolina and Georgia. 



The hairiness of the exterior of the pileus is due to the irregu- 

 larly curved and interwoven hyphse which form the surface 

 layer of the pileus ; these hyphse are colorless and about 3 m in 

 diameter, and they bear scattered but large incrusting granules. 

 The angular spores of this species are often octahedral in form 

 and are noteworthy for Cyphella; at maturity, they are attached 

 to the basidium by sterigmata becoming 6 ij. long and so finely 

 attenuated that the attachment of the spores to the basidia is 

 made out with difficulty. This species may be readily known 

 by its occurrence on bark of Juniperus virginiana and by its 

 angular spores.
