at all, or very slightly constricted at the septum, base 
generally rounded, smooth, brownish, 26— 36 X 15— 26 p, 
pedicel short, deciduous. 
The sori are much larger, crust-like, and cause more swel¬ 
ling and deformation of the host-plant, than in the case of 
Puccinia bulbocastani, Fuckel. 
This species is represented in Cooke, Fung. Brit, i. No. 
39a, and in 2, No. 327.
