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, diifers in 

 the superficial ascophore and the 3 many-septate spores. 

 Finally the present genus approaches Phacidium in having 

 the ascophore at first immersed in the substratiim and 

 erurnpent, but differs in the ascophore protruding from the 

 substratum, ' k arid not remaining immersed at maturity. 

 Coccomyces and Coccophacidium differ in having the spores 

 arranged in a parallel fascicle in the ascus.

 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-seriatc 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 p.; paraphyses hyaline, rather stout, sometimes 

 branched.

On living clover leaves. 



The ascophores are situated on the under surface of the 

 leaves, and resemble the pustules of a Puccinia in appearance, 

 being surrounded by the ruptured epidermis.
