Mycologia 



The type species, Discina ancitis, a large and conspicuous 

 fungus, is frequently collected from New York State west to 

 Washington. A number of specimens have been received from 

 J. R. Weir to whom the writer is indebted for the accompanying 

 photograph. Peziza Warnei was described by C. H. Peck from 

 material collected at Oneida, New York, by H. A. Warne. Ex- 

 amination of some of this material in the herbarium of the New 

 York Botanical Garden shows it to be identical with Discina 

 an c His. 



Discina leucoxantha is also a large and attractive species but 

 is less frequently collected. It is readily recognized by its light 

 color and by the truncate appendages which mark the spores. 

 Several specimens have been received from Stewart H. Burn- 

 ham, collected at Hudson Falls, New York. Other specimens 

 from New York and Maryland have been examined. Discina 

 convolnta differs in its extremely convolute hymenium. Whether 

 this character is constant must be determined by future col- 

 lections. 



Peziza apiculate of Cooke also doubtless belongs to Discina as 

 here treated although the occurrence of this species in North 

 America is somewhat doubtful. A very small specimen collected 

 by B. O. Dodge in Bermuda has been doubtfully referred to this 

 species. Also Peziza elaeodes of Clements seems to agree al- 

 though no specimen has been seen. Doubtless other apiculate 

 spored species of cup-fungi occur in North America and it is 

 hoped that more will come to light. A synopsis of the North 

 American species follows : 



37. Discina Fries, Summa Veg. Scand. 348. 1849 



Apothecia medium to large, sessile or short-stipitate, fleshy or 

 waxy, light or dark-colored ; asci cylindric or subcylindric, very 

 long, usually showing a tendency to become spirally twisted; 

 spores ellipsoid, appendiculate and often sculptured, hyaline or 

 faintly colored ; spore appendages apiculate or truncate ; paraph- 

 yses rather stout. 



Type species, Discina perlata Fries. 



Apothecia dark-colored ; spore appendages apiculate. 



Apothecia large, 6-7 cm. or more in diameter. 1. D. ancilis.
