named by Fuckel was at hand its exact status cannot be determined. 

 The material from Germany on Melica uniflora and Calamagrostis epigeum 

 which was distributed by Sydow belongs to Colletotrichum cereale. The 

 conidia average about 20 x 3.5ju. 



7. Vermicularia sanguinea Ellis & Halsted 



This species is based on material collected at Ames, Iowa, by Dr. B. D. 

 Halsted, on a cultivated species of Panicum of European origin. The 

 original spore measurements of 20 to 22 x Q/x is entirely too large, as the type 

 specimen shows a range of 18 to 22 x 4 to 6/*. While the spores are a trifle 

 broad in proportion to their length the discrepancy does not appear to be 

 sufficient to warrant its retention as a distinct species. The chief distinc- 

 tion appears to be the reddish margin of the infected area, which may be 

 due rather to the chemical composition of the leaf than to a difference in 

 the parasite. Other specimens so named are on Panicum Crus-galli (Kan- 

 sas) and on Sorghum sp. (Alabama). The species was later transferred 

 to Colletotrichum. 



8. Vermicularia graminicola Westend. 



The cotype material of this species which was examined was not in a 

 condition to warrant an opinion as to the identity of the fungus, as no 

 acervulae were found. However other European material issued by 

 Allescher and Schnabl and by Roumeguere under this name is a true 

 Vermicularia. American material which was placed under this name, but 

 which is in reality identical with Colletotrichum cereale, was examined on 

 Anthaenantha rufa (Florida), on Cenchrus tribuloides (Delaware), and on 

 Poa sp. (New Jersey). 



9. Vermicularia affinis Sacc. & Briard 



The type of this species was collected in France on some undetermined 

 species of grass. As no authentic material was at hand for study its 

 identity has not been established, but the description would indicate a 

 true Vermicularia. Material so named from Mississippi on both An- 

 dropogon Hallii and Panicum Crus-galli is a Colletotrichum which agrees 

 in every respect with C. cereale. 



10. Vermicularia sp. 



Undetermined material so labeled on Dactylis glomerata (Mississippi) 

 and on Arundinaria sp. (Alabama) evidently belong to the species of 

 Colletotrichum under consideration. While setae and conidia agree in
