This common form having aecia on Ribes sp. was first cultured 

 by Klebahn in 1892. The species has since been extensively studied 

 by the culture method in both Europe and America (Klebahn, Die 

 Wirtsw. Rostp. 295-302. 1904) under various names. 



In America, Arthur began culture work in 1901 and has reported 

 the results of numerous cultures (Jour. Myc. 8: 53. 1902; 10: 11. 

 1904; 11:59. 1905; 12:65. 1906; 13:196. 1907; 14:13. 1908; 

 Mycol. 4: 13. 1912; 7: 67. 1915; 7: 78. 1915). The species is 

 doubtless represented by several biological strains and further culture 

 work will need to be conducted in order to determine their limits. 

 Considerable confusion has resulted on account of the variable number 

 and position of the germ pores in the urediniospores.
