Sori in the seeds, showing when the legumes are broken open as 
reddish brown dusty spore masses which have destroyed most of 
the seeds; spore balls reddish brown, ovoid to spherical, rather firm, 
composed of 3-25 (usually 7-12) spores, chiefly 27-60 p in length ; 
spores in optical section triangular to polygonal or when free also 
showing irregular oblong forms, on free surface provided with 
usually prominent papillae that sometimes vary to spiny processes, 
15-25 p, chiefly 15-20 p, in length.

As considered here the various species reported on leguminous

the available European and American specimens there did not seem 
to be any reliable basis for distinguishing these species on the dif¬ 
ferent hosts. The specimens on Astragalus showed as great
