occasionally confluent, early naked, pulverulent, or compact in germinating sori, ruptured 
epidermis not conspictious, cinnamon-brown, becoming cinereous by germination, more rarely 
solitary or gregarious and then usually larger, 0.5-0.8 mm. across, pulverulent, with ruptured 
epidermis conspictious; teliospores ellipsoid or somewhat fusiform, 14-18 by 24-34 y, rounded 
or obtuse above, rounded or narrowed below, not or slightly constricted at septum; wall 
golden- or light cinnamon-brown, thin, 1-1.5 4, thickened 3-5 « above, smooth or very mi- 
nutely verrucose-rugose, best observed when dry; pedicel colorless, short, deciduous, or in 
pulvinate sori twice length of spore.
