O. Pycnia epiphyllous, in small groups, honey-yellow, becoming brownish, globoid or 
conic, 70-80 w in diameter; ostiolar filaments 30-40 uy long. 
II. Uredinia of the primary form grouped about the pycnia, otherwise similar to the 
secondary form; secondary uredinia amphigenous, scattered, round or elliptic, 0.3-1 mm. 
across, early naked, pulverulent, cinnamon-brown, ruptured epidermis conspicuous; wuredinio- 
spores of both forms oblong, oblong-ellipsoid, or oblong-obovoid, 16-25 by 27-42 4; wall 
cinnamon-brown, 1.5-2.5 uw thick, closely and rather prominently echinulate above, less con- 
spicuously so or smooth below, the pores 8, in two transverse bands of 4 each, the upper super- 
equatorial or sometimes equatorial, the lower subequatorial. 
III. Telia amphigenous, scattered or somewhat crowded, round or ellipsoid, 0.8—1.5 mm. 
across, early naked, pulverulent, brownish-black, ruptured epidermis noticeable; teliospores 
ellipsoid or oblong-ellipsoid, 23-30 by 37-55 yw, rounded or slightly narrowed above and below, 
not or only slightly constricted at septum; wall dark chestnut- or chocolate-brown, thick, 
2.5-~4 uw, thickened at apex, 5—7 u, closely and finely verrucose, often appearing smooth when 
wet; pedicel colorless, inflated, fusiform-oblong, 27-39 » broad, 65-96 uw long.

O. Pycnia amphigenous, fairly numerous on yellowish or purplish spots with the uredinia, 
small, punctiform, noticeable, honey-yellow becoming cinnamon-brown, flattened-conic, 130- 
160 » wide by 65-76 » high; ostiolar filaments short. 
IE. Uredinia of the primary form epiphyllous, circinating about the pycnia in groups

globoid, 20-26 by 22-29 4; wall pale-yellow or colorless, 2-3 » thick, moderately and promi- 
nently echinulate, the pores 3 or 4, equatorial, rather indistinct.
