EXSIC: 

 Kellerman and Swingle, Kansas Fungi, 44. 



Not a very abundant or widely distributed species. The 

 uredospores have golden yellow walls, that are thin, and are 

 minutely and closely verrucose. The pores are small and 

 difficult to count, but are certainly more than four, and scat- 

 tered over the surface without order.

Orig. Descr. " Uromyces Brandegei. — Spots none; sori scattered, rarely 

 slightly confluent, prominent, orbicular, elliptical or oblong, black; 

 spores subglobose or broadly elliptical, rough with minute warts or 

 papillae, .0012-. 0016 of an inch long, .001 1-. 0015 broad; pedicel hyaline, 

 usually equal to or exceeding the spore in length." — Peck, 1. c. 



Second Descr. "The two-celled spores are oval, obtuse at both ends, 

 smooth or somewhat roughened in the upper part, and measure from 

 30-38// X 19-24//. The one-celled spores are dark brown, like the two- 

 celled, obovate, distinctly papillate or roughened in the upper part, and 

 of about the same dimensions as the two-celled, perhaps a trifle smaller." 

 Farlow, 1. c.
