over-wintering leaves of this grass were found to bear telia. On June 1 

 at the same place this grass was found in fruiting condition bearing 

 fresh telia (2239). The grass proved to be Eatonia pallens. Examina- 

 tion showed the rust to be that described by Arthur on P. Eatoniae.

 Arthur conducted culture experiments in 1905 (Jour. Myc. 12:23. 

 1906) showing that an aecidium resembling in every way the common 

 one on Eupatorium species could be induced by sowings with teliospores 

 from Eleocharis. He used teliospores on Eleocharis palustris from Wis- 

 consin to successfully infect Eupatorium perfoliatum, with subsequent 

 development of aecia — two trials. These results were confirmed in 1906 

 and 1908 by the same author (Jour. Myc. 13:197. 1907; Mycol. 1:233. 

 1909) when typical aecia were produced on Eupatorium perfoliatum 

 following infection by teliospores from E. palustris collected in Kansas 

 and Indiana.
