According to Dietel this is 4czdium album Clint. (4cidium 
Porosum Pk.). No experiments indicating this are cited. The 
specimen reported below differs from Dietel’s description in 
that the teleutospore sori are found on the leaves (not on 
the stem), and the color of the sori is not black but dark 
brown. 
This material (Holway 25) was reported by Arthur * as 
Uromyces orobi (P.) Wint. (II), and (Holway 14) as 4cidium 
porosum.

Arthur’s recent experiment ¢ although too incomplete to be 
conclusive indicates strongly that Uromyces euphorbze is an au- 
teecious Euuromyces.
