Cups subsessile, irregular, 1 to 2 inches in diameter; hymen- 

 ium bright orange, externally whitish; asei cylindrical; spor- 

 idia 8, elliptic, 2-guttulate, rough with the projections of 

 the net-like reticulations, 15 to 17 by 8 microns; paraphyses 

 slender, enlarged upwards, filled with orange granules. 



Habitat — In a grassy place at the base of a large oak stump, 

 also in clamp places in woods, among leaves and moss, in the 

 fall; Iowa City. 



The finest specimens were found at the base of a large stump 

 in open woods near Iowa City. When growing alone the 

 plants are quite regular but when crowded, become irregular 

 in form. Those forms found in damp shady woods were more 

 regular in outline but much smaller in size. They are recog- 

 nized at once on account of their large size and bright orange 

 color.
