 According to Dietel this is ^Scidium album Clint. (scidt'um 



porosumPk.). 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 sEcidium 

 porosum.

Arthur's recent experiment f although too incomplete to be 

 conclusive indicates strongly that Uromyces euphorbia is an au- 

 toecious Euuromyces.
