Orig. Descr. " II and III. Sori amphigenous or mostly epiphyllous, 

 sparsely scattered, very small, sublinear to linear by confluence. Ure- 

 dosori soon appearing through the ruptured epidermis, which falls 

 away leaving the spore-mass mostly superficial. Uredospores sub- 

 globose or ovate, 16-20 X 14-16//, epispore smooth but irregular, thick 

 (about 2-3^), hyaline; nucleus consisting of coarse, bright golden-yel- 

 low, granular matter. Teleutosori almost wholly superficial. Teleuto- 

 spores bright yellowish-brown, short-elliptical, rounded, slightly con- 

 stricted, nearly equal, lower cell sometimes wedge-shaped, not thickened 

 at apex, 25-30 X 15-18/*. Pedicels hyaline, short, weak and shriveled, 

 inclining to fall away. Differs from Puccifiia buchloes Schaf. on the 

 same host, in its smaller teleutospores, not thickened at the apex, and 

 in its weak, shriveled, hyaline pedicels."

This species has very small spores, without apical thicken- 

 ings. The uredospores have colorless walls and orange-yel- 

 low contents when fresh. The surface is minutely and 

 densely verrucose with occasional slight echinulation. The 

 pores are minute, obscure, and scattered over the surface 

 without order. 



The species has not yet been reported from any locality 

 outside the state of Kansas. The type was collected Sept. 

 18, 1894.
