THE DISCOMYCETES OF EASTERN IOWA. 26 1 



The hairs, with which the exterior is covered, are more num- 

 erous and much longer near the margin, forming a fringe 

 which especially in the young specimens projects inward. The 

 cups are often 1 inch in diameter but generally smaller.

Cups scattered or gregarious, fleshy, sessile; externally as 

 well as the elevated margin, brown, clothed with rather long, 

 septate, brown, sharp pointed hairs; hymenium at first concave 

 then plane, bright red; asci cylindrical; sporidia 8 elliptic, 

 smooth, when fresh, often fitted with numerous guttulae and 

 granules, generally with 2 or 3 large guttulae, 20 to 22 by 12 

 to 14 microus; paraphyses simple or branched, enlarged at 

 their apices, often spirally marked, filled with orange granules. 



Habitat — On decaying wood in the fall; Iowa City. 



The plants of this species are very closely related to one or 

 two other common species which are not described in this 

 paper, but may be easily distinguished by the bright red disc 

 and the smooth spores which are filled with numerous gran- 

 ules. The hairs on the exterior are long and dark colored. 

 The planis are common in the late fall on much decayed wood 

 in wet places.
