286 NATURAL HISTORY BULLETIN. 



hymenium bright scarlet, whitish externally and clothed with 

 a dense covering of straight or somewhat flexuose, hyaline 

 hairs, erect and longer near the margin; asci cylindrical; spor- 

 idia 8, elliptical granular within, 20 to 25 by 11 to 12 

 microns; paraphyses filiform, slender. 



Habitat — On sticks half buried in the ground in spring; 

 Iowa City. 



The cups are stipitate, the length of the stem varying ac- 

 cording to the depth at which the sticks from which they grow 

 are buried. This is a common species in the woods in spring, 

 and recognized on account of the bright colored hymenium 

 and the dense covering of white hairs on the exterior.
