Other species of Gleosporium attacking members of the genus 
Ribes, the genus to which the cultivated currants and gooseber- 
ries belong, are G. curvatum Oud. on leaves of R. nigrum, the 
black currant; G. tuwbercularioides Sacc. on leaves of R. aureum, 
the Missouri currant; and G. ribicolum E. & E. on fruit of the 
English gooseberry. 
AMOUNT OF DAMAGE DONE. 
Although the fungus Gleosporium ribis is widely distributed 
over Europe, Asia, Australia and North America, and has long 
been known to mycologists, it seems to have attracted very little 
attention as a fungus of economic importance. While it is fre- 
quently mentioned in works on fungi, it is not often spoken of 
as doing any serious damage to currants. 
The first mention of its occurrence in this country seems to 
have been that made by Berkeley,’ in 1873, who reported it on 
leaves of black currant collected in Connecticut. In 1884 Peck? 
found it on the leaves of the fetid currant, Ribes prostratum, in 
the Adirondacks. According to Dudley” and also Peck" there 
was a serious outbreak of the disease in New York State in the 
season of 1889. Prof. Dudley, at that time Cryptogamic Botanist 
of the Cornell Experiment Station, made the disease the subject 
of a two-page article which was published as a part of Bulletin 15 
of that Station and also inthe Annual Report of the same Station 
for 1889. Although so brief that Prof. Dudley himself called it 
a note, the article is, even to the present time, the most compre- 
hensive published account of currant anthracnose as it occurs in 
America. He reports the disease abundant on white currants at 
Ithaca and destructive to red currantsin thevicinity of Rochester.
