0.2-0.8 mm. across, round, early naked, pulverulent, cinnamon-brown, ruptured epidermis 
noticeable; urediniospores flattened laterally, globoid or broadly ellipsoid when pores are

naked, ruptured epidermis noticeable; teéliospores broadly ellipsoid or oblong, 26-40 by 
32-58 4; rounded or obtuse above, rounded or occasionally slightly narrowed below, slightly 
or not constricted at septum; wall chestnut-brown, smooth, 3-6 » thick, slightly thickened 
at apex and over pore of lower cell near septum by a low or frequently somewhat abrupt 
subhyaline umbo; pedicel colorless, 5~9 » thick, fragile, flexuose, the wall thin, once to several 
times length of spore, often deciduous.
