In 1901 Arthur (Jour. Myc. 8: 54. 1902) first began 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 

 Ditlichium and from many species of Carex from various parts of 

 North America (Jour. Myc. 8: 54. 1902; 11 : 58. 1905; 12: 15. 

 1906; 14: 13. 1908; Bot. Gaz. 35: 15, 21. 1903; Mycol. i: 233. 

 1909; 2: 224. 1910; 4: 15, 16. 1912; 7: 70, 81. 1915). Eraser in 

 191 1 (Mycol. 4: 181. 1912) confirms Arthur's results in part by 

 successfully infecting Aster aciiminatiis using telial material from 

 Carex trisperma L.
