The aecidiospores of this species are readily distinguished from those of 
P. Stohaeae by the presence of the large prismatic warts on the surface 
of the spores, whereas the spores of P. Stohaeae are delicately verruculose. 
This very evident difference between the aecidiospores does not appear 
to have been noted before.

Uredospores. — Sori generally hypophyllous, on irregular pallid-yellow or 
brown spots, scattered or in clusters, about 1-li mm. diam., frequently 
circinate, pulverulent, cinnamon ; spores globose, subglobose, or ellipsoid, 
echinulate, brown, 24-32 x 17-27 /x. 
(Teleiitospores. — Mixed with the uredospores, ellipsoid or oblong-ellipsoid, 
rounded at the apex, slightly thickened, scarcely constricted, usually rounded 
at the base, minutely warted, chestnut-brown, 35-43 x 20-25 /x ; pedicel 
stout, hyaline, persistent, 35-60 /x long ; mesospores subglobose or pyriform,
