Other species of Glceospm^ium attacking members of the genus 

 Rihes, the genus to which the cultivated currants and gooseber- 

 ries belong, are G. curvatum Oud. on leaves of R. nigrum, the 

 black currant; G. iiibercularioides Sacc. on leaves of R. aureum, 

 the Missouri currant j and G. riUcolum E. & E. on fruit of the 

 English gooseberry. 



AMOUNT OF DAMAGE DONE. 



Although the fungus Glceospw'ium 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 in the 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^^ i\^q disease abundant on white currants at 

 Ithaca and destructive to red currantsin the vicinity of Rochester. 

 Peck^2 says: "A currant-leaf fungus, GlooospoHum ribis, has also
