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; I0: II. 
EQOA; EL: 59. “1905; 12: 65: 1906; 13: 196. 40077 14712. 1008; 
Mycol. 4-132. 1912; 72> 67; TO15; 7:78: TOES). he 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.
