Tussilago farfara. He infected the fecial host by sowing with telio- 

 spores from P. anmm. 



Additional observations and culture work have been recorded by 

 various European authors, which has been summarized by Klebahn (Die 

 Wirtw. Rostpilze 290. 1904).

 The Aecidium on Fraxinus known as A. Fraxini Schw. was first 

 shown by Arthur (Bot. Gaz. 29:275. 1900) to have telia on Spartina 

 cynosuroides. He obtained the development of aecia on F. viridis fol- 

 lowing sowings of telial material from Iowa and Nebraska. In 1904, 

 1905, 1907 and 1909 (.Jour. Myc. 11:57. 1905; 12:16. 1906; 14:14. 1908; 

 Mycol. 2:225. 1910) similar results were obtained on F. lanceolata using 

 telia from Iowa, Kansas, Nebraska and North Dakota. 



In 1908 the writer sent telial material collected at Lewes on S. cyn- 

 osuroides and S. stricta to Dr. Arthur for culture work. Successful 

 infection of F. lanceolata with development of aecia was obtained from 

 cultures with telia from both hosts.
