If. Uredinia mostly hypophyllous or caulicolous, numerous, scattered or in concentric 
circles on discolored spots, sometimes crowded into irregular patches, round or irregular, 
0.2-1.5 mm. in diameter, rather early naked, somewhat pulvinate becoming pulverulent, light 
chestnut-brown, ruptured epidermis conspicuous; urediniospores globoid, obovoid, or broadly 
ellipsoid, 16-24 by 21-30; wall cinnamon- or light chestnut-brown, 1.5-2.5 » thick, finely 
and closely echinulate, the pores for the most part 2 and equatorial, sometimes 3 and placed 
irregularly. 
III. Telia mostly caulicolous and hypophyllous, usually occurring on stems late in season, 
not particularly numerous, scattered, elliptic, 0.5-1.5 mm. long, tardily naked, pulvinate, 
becoming somewhat pulverulent, blackish-brown, ruptured epidermis conspicuous; teliospores 
usually oblong or clavate-oblong, 18-29 by 36-55 », sometimes broadly ellipsoid, smaller, 
18-26 by 29-45 y, rounded or acute above, rounded or narrowed below, moderately constricted 
at septum; wall chestnut-brown above, somewhat lighter below, 1.5—2.5 » thick, thickened to 
7-10 » above, smooth; pedicel pale-yellow or colorless, up to three times length of spore.
