 92-94. 19 1 7) has also conducted very extensive cultures and proven 

 the genetic connection with aecia on many hosts. 



In 1915, Arthur (Mycol. 8: 135. 1916), using telial material 

 sent by the writer collected by Mr. C. C. Cate at LaGrand, Ore., 

 obtained the development of aecia on Chenopodium album. This is 

 the only culture made with material from the Pacific coast. 



The aecia on Sarcobatus are included here on the strength of 

 culture work conducted by Arthur, in which he obtained aecia on that 

 host using telial material on Distichlis from Nevada. The matter is 

 complicated by the fact that Bethel (1. c.) finds that the aecia on this 

 host in Colorado go to P. luxiiriosa (cf. 124) and P. siibnitens can not 

 be made to infect Sarcobatus. It is possible that the two species repre- 

 sent closely related biological forms.

This micro-form is exceedingly abundant in western Oregon. This 

 species is morphologically correlated with the telial stage of P. abun- 

 dans (cf. 59), which has aecia on the same host, as has been pointed 

 out by Travelbee (Proc. Ind. Acad. Sci. 1914: 233. 1915).
