iia. On Aster macrophylliis. has the sori scattered, mostly 

 not confluent, with the spores dark brown, 16-20 by 32-40,". 



I lb. On . \ster c/iamissom's, has the sori more densely crowd- 

 ed, the spores paler, longer, and narrower, 12-16 by 40-52^. 

 This is the form called Puccinia gerardiae Pk., but there 

 seems no good reason for separating it, as both forms have 

 been found on the same leaf on Aster sagittifolius. 



lie. On Seiiecio sp. The sori occur on dead spots, which 

 fall out. leaving more or less round holes. The sori are smalL 

 brown, with spores poorly developed, the walls thin, and the 

 apices much less thickened.
