In 1901 Arthur (Qiour: Myc: 8:54. 1902) first bégan culture 
work showing that aecia which occur commonly on Aster, Solidago and 
related hosts are genetically connected with uredinia and telia on 
various species of Carex. The culture work conducted by Arthur is 
extensive and extends over a period of years from 1901-1914. In this 
series of culture work aecia have been produced on various species of 
Aster, Solidago, Erigeron, Leptilon and Euthamia, using telia from 
Dulichium and from many species of Carex from various parts of 
North America our. Miyec. 854° 1902; Ir: 58.> 19055 "12eaSs
