riigosa (?) and S. hicolor by sowing teliospores from Carex defiexa from 

 Nova Scotia. Similar results were obtained on Eutliaviia gramiyiifolia 

 when infected with teliospores from C. scojiaria and on Soli dago sp. 

 from C. intumescens. 



Arthur in 1912 (Mycol. 7:75. 1915) reports infection of Aster 

 paniculatus and S. canadensis following sowings of teliospores from 

 C. intumescens collected in New York and in 1914 (Mycol. 7:83. 1915) 

 on A. T weedy i from C. tribnloides collected in Indiana. 



The aecia obtained in these cultures are indistinguishable from the 

 aecia resulting from sowings of the correlated Puccinia. Field collec- 

 tions of aecia on Aster, Solidago, etc., can be properly referred only 

 when close observations of the source of infection are made.

When teliosporic material from 5. cynosuroides collected in Ne- 

 braska was used by Arthur to inoculate Steironema ciliata (Jour. Myc. 

 12:25. 1906; 14:17. 1908) aecia developed. In 1909 Arthur (Mycol. 

 2:229. 1910) confirmed the results with S. ciliata and also records 

 successful infection of S. lanceolata. In 1910 (Mycol. 4:29. 1912) the 

 development of aecia was obtained on Polemonium reptans following- 

 sowings of teliospores from S. cynosuroides collected in North Dakota 

 and Colorado. 



Fraser in 1911 (Mycol. 4:186. 1912) obtained infection re.sulting
