leaves ; others are saprophytes, and occur on fading leaves, 

 dead or dying herbaceous stems, wood, &c. 



Closely allied to Mollisia, in fact to be distinguished only 

 by being truly erumpent, a primitive habit from which those 

 species at present constituting the genus Mollisia have 

 emerged. Belonidium, another closely allied genus, differs in 

 the superficial ascophore and the 3-m any-septate spores. 

 Finally the present genus approaches Phacidium in having 

 the ascophore at first immersed in the substratum and 

 erumpent, but diifers in the ascophore protruding frpm the 

 substratum, [and not remaining immersed at maturitj'. 

 Coccomyces and Coccophacidium differ in having the spores 

 arranged in a parallel fascicle in the ascus.

Pseudopeziza trifolii. Fckl., Symb. Myc, p. 290; 

 Sacc, Syll., viii. n. 2970. 



Epiphyllous, sessile, gregarious in small clusters on dark 

 spots, erumpent and girt by the ruptured epidermis, soon 

 plane, dingy yellow, glabrous, about |- mm. across ; exci- 

 pulum parenchymatous, margin somewhat irregular; asci 

 clavate, 8-spored ; spores 2-seriate or sometimes almost 

 obliquely 1-seriate, hyaline, elliptic-oblong or sometimes 

 inclined to be broadest at the apex, usually 2-guttulate, 

 10-15 X 5-6 /*; paraphyses hyaline, rather stout, sometimes 

 branched.

On living clover leaves. 



The ascophores are situated on the under surface of the 

 leaves, and resemble the jpustulesof a Piica'm'a in appearance, 

 being surrounded by the ruptured epidermis.
