a stem-like base below; asci cylindrical operculate; sporidia 8 

 elliptic, smooth, 20 to 22 by 10 microns, granular within; 

 paraphyses slender, enlarged upwards, filled with grannies. 



Habitat — On rich ground and dung heaps in the fall, Iowa 

 City. 



This species has been found but once in a large mass grow- 

 ing on a dung pile which was mixed with straw. The plants 

 were at first hemispherical but in older species the margin 

 becomes wavy. The flesh is very brittle and resembles wax 

 as is indicated by its specific name. Especially when young, 

 the plants have a mealy appearance on the outside, and cups 

 are sometimes produced into a short stem below. 



Genus VI— G A L A C T I N I A Cooke. 



Receptacle sessile, cup-shaped, entire, fleshy, when wound-
