O. Pycnia unknown. 
I. Aecia epiphyllous, gregarious on pale spots, 2-4 mm. across, opening by a pore, definitely 
globoid, 190~220 y» in diameter, surrounded and overarched by the host-tissue; peridium want-

III. Telia epiphyllous or amphigenous, few, at first surrounding the aecia, later occasion- 
ally concentric in circular groups on round or irregular pale spots, minute, 0.5 mm. in diameter, 
early naked, compact, brown, becoming cinereous upon germination; teliospores ellipsoid, 
obovoid, or clavate, 16-20 by 24-32 u, rounded above, rounded or narrowed below, germinating 
at maturity; wall colorless, thin, about 1», 3-44 thick at apex, smooth; pedicel hyaline,

dark cinnamon-brown, 1.5-2 » thick, thickened at apex into a 3~6y4 thick colorless papilla, 
conspicuously longitudinally verrucose-rugose when dry, somewhat inconspicuous when wet;
