with some uncertainty on account of the lack of culture evidence. 

 They are included on the grounds of morphological similarity. 

 The collection of C. oligocarpa is from Wisconsin and is further 

 east than any of the others or any of the aecial collections but 

 appears to belong here. With the exception of a single collec- 

 tion of pyenia on Artemisia from Iowa this stage of the species 

 is not known to extend east of the Dakotas and Nebraska.

II. Urediniospores obovoid or broadly ellipsoid, 13-18 X i&- 

 23 fi; wall light cinnamon-brown, 1-1.5/x thick, finely and rather 

 inconspicuously echinulate, the pores 2, in the upper part. 



III. Teliospores clavate oblong, 12-18 X 2 9~45 roundish or 

 obtuse above, usually slightly narrowed below, slightly constricted 

 at the septum; wall chestnut-brown, 1-1.5/x thick, much thicker 

 above, 7-13 n; pedicel nearly colorless, about length of spore.

Distribution : In the telial stage known only from Madison, 

 Wis., and Valentine, Nebr., the aecia have been collected also in 

 Iowa, South Dakota, and New York.

This is a restricted species as to hosts both for the aecial and 

 telial stages. The urediniospores are very like those of Puc. 

 asterum but differences in the teliospores and the interval between 

 the aecial host families seem sufficient to maintain this as a good 

 species.
