This common subepidermal species, as here considered, includes 

 nearly if not all the forms having aecia on Ranunculaceous hosts. 



Dietel (Oesterr. bot. Zeitschr. 42: 261. 1892) was apparently 

 the first to culture this species. Klebahn (Die Wirtsw. Rostpilze 292. 

 1904) has presented a summary of Dietel's work together with that of 

 other European investigators. 



In America, Arthur has conducted extensive culture work beginning 

 in 1904, using telial material from various parts of the country, on five 

 different genera of grasses representing ten species, and has success- 

 fully cultured them on five genera of Ranunculaceae. His work indi- 

 cates the presence of a number of well-marked races. (Jour. Myc. 11 :
