to Saccardo's Sylloge it is found that the genus is included in the 

 group Tubercularieae, where it ranks first in the section Amer- 

 osporae, characterized by having the conidia continuous or one- 

 celled. Now, as a matter of fact, most of the species have many- 

 celled conidia and technically should be included in section Dic- 

 tyosporae, only three or four species, including, the one under 

 consideration, having one-celled conidia. The sum-total of close 

 affinity between the various species appears to have been too ob- 

 vious to admit of their separation into two genera, placed miles 

 apart, as would have been the case if numbers and arrangement 

 of septa had prevailed. Saccardo, however, temporarily solved 



Epicoccum torquens Massee 

 I. Capsule of IVeisia viridula showing the parasite in situ. 2. Conidiophores 

 originating from peripheral cells of the stroma. 3. Free conidia of E. torquens, side 

 and basal views. 4. The epispore is described as minutely warted, and it appears to 

 be so under a mag. of 400 diam. ; the apparent warting is however in reality due to 

 the epispore becoming rigid at an early stage of development, and being afterwards 

 torn into areolae by the continued increase in size of the spore, as shown in the figure. 

 5. Conidium (many-celled) of E. purpurascens Pers. i, slightly magnified; 2, 3, 

 and 5, X 400 ; 4, X 1200. 



the problem by describing the many-celled conidia as having the 

 surface "reticulated," such reticulations being in reality the lines 

 of septa dividing the spore into several cells. 

 The species may be defined as follows : 



Epicoccum torquens sp. no v. 



Stromata almost circular, convex, isolated or sometimes more 

 or less confluent, about 350// diam., brownish; conidia globose, 

 sessile, i -celled, brown, minutely warted, 15-20 fi diam. ; conid-
