Mycologia 



Thelocarpon fimicola Fink sp. nov. 



Superficial thallus absent, or not readily distinguishable from the 

 layer of algae .growing over the surface of the substratum ; apo- 

 thecia minute and spheroidal, 0.05 to 0.15 mm. in diameter, pale 

 within and surrounded by a thin thalloid veil; asci at first cylin- 

 drical, but becoming variously ventricose as the spores mature, 

 most commonly distended toward the center and tapering toward 

 both ends ; paraphyses inconspicuous and disappearing as the fruit 

 matures; spores one-celled, minute, hyaline, spheroidal to oblong, 

 2 to 4 by 1.5 to 2 mic, very numerous in each ascus. 



Growing with algae on cow dung, in a damp wood, near Conway, 

 Rockcastle County, Kentucky. The algae which were growing 

 on the substratum gave it a coloration which could be detected from 

 a standing position, but there is little evidence of the presence of 

 algae in the dried specimens.

Another Green-spored Genus of Gill-fungi 



While working over specimens of Pilosace for the article on 

 dark-spored agarics, published earlier in this number, I discovered 

 some interesting things which did not properly belong under that 

 title, so I have set them apart here. 



Chlorophyllum Mass., based on the plant known as Lepiota 

 Morgani, was published in 1898 and discussed in N. Am. Flora 10 : 

 64. 1914. It differs from Lepiota in having green spores. 



Chloroneuron Murrill, based on the tropical American species, 

 Neurophyllum viride Pat., was published in Mycologia 3: 25. 

 191 1 and discussed in N. Am. Flora 9: 172. 1910. The spores 

 are green and the lamellae fold-like, as in Chanter el. 



In the new genus here described the spores are green and the 

 lamellae adnate or adnexed, as in Hypholoma or Psathyra. 

 Schulzeria Bres. is a "Lepiota without an annulus," having free 

 gills and hyaline spores. Massee's S. Eyrei, however, has green 

 spores and an appendiculate veil, with free gills. 



Chlorosperma gen. nov.
