1 9 *>] BISB I — UROM \ 'CES 2 I 3 



The Sydows (Monog. Ured. 1:3. 1909) misapplied Lager- 

 heim's name to the species with uredinia, now called Uromyces 

 bidenticola (P. Henn.) Arth. The situation in regard to these two 

 rusts is discussed by Arthur (Mycologia 9:71. 1917), and he also 

 (Mycologia 10:127. I 9 I 8) suggests that it is possible that a 

 fixity of life cycle may not occur in these Bidens rusts. U. Bidentis 

 is correlated with U. Bidenticola, differing only in the life cycle 

 and in the characters of the telia, which are coalescent and thickened 

 into cushions in U. Bidentis. Specimens are at hand also from 

 South America; Lagerheim's collection from the type locality 

 has been examined.

This rust, first described upon Sophora sericea from Colorado, 

 and made the type of the genus Telospora, has been found to possess 

 uredinia. Olive, in his paper on intermingling of perennial sporo- 

 phytic and gametophytic generations, etc. (Ann. Myc. 11:309. 

 1913), mentions that Arthur has called attention "to the fact 

 that Uromyces Sophorae -seems to possess a similar habit [that is, 

 an intermingling of mycelial to the perennial rusts under dis- 

 cussion." In any event, the presence of uredinia, in some cases 

 at least, suffices to exclude this species from the short cycle forms.
