ellipsoid, 26-35 by 35-50, rounded at both ends, not or slightly constricted at septum; 
wall dark chocolate-brown, uniformly 3-5 » thick, rather obscurely reticulate, the areolae 
about 2-3 » across; pedicel colorless, up to 50 long, in water swelling next to the spore

O. Pycnia hypophyllous, crowded in circular groups 1-1.5 mm. across, noticeable, yellowish 
or whitish, globoid, 110-130 w in diameter; ostiolar filaments up to 90 p long. 
II. Uredinia of the primary form circinating about the pycnia upon brilliant red spots, 
0.2-0.7 mm. in diameter, otherwise similar to the secondary form; secondary uredinia mostly 
hypophyllous, scattered, causing smaller reddish discolorations, circular or oval, 0.2-0.8 mm. 
across, somewhat tardily naked, cinnamon-brown, ruptured epidermis noticeable; uredinio- 
spores of both forms broadly ellipsoid or globoid, 32-35 by 34-43 4; wall pale golden-brown, 
very thick, 4-7 , sometimes showing a thin outer colorless layer, 1 « or less, sparsely and 
prominently echinulate, the pores 4, equatorial, rather indistinct. 
III. Telia hypophyllous, scattered, round, 0.3-0.8 mm. in diameter, early naked, com- 
pact, blackish, ruptured epidermis noticeable; teliospores broadly ellipsoid, 37-41 by 50-58 n, 
rounded or obtuse above, rounded below, not constricted at septum; wall chestnut-brown, 
very thick, 4-7 yu, thicker and paler at apex, 8-10 u, closely pitted, the pits 2-3 » in diameter; 
pedicel colorless below, yellowish-brown next to spore, up to 70 » long, roughened and slightly 
swollen at the base.

noticeable, dark-brown, globoid, 70-128 » in diameter; ostiolar filaments up to 40 u long. 
II. Uredinia hypophyllous, few, circinating about the pycnia, oval or oblong, 0.2-0.8 
mm. long, originating deep within the tissues and remaining partly covered by them, opening 
by slit or large pore, somewhat pulverulent, dark cinnamon-brown; urediniospores broadly 
ellipsoid or obovoid, 25-32 by 39-45 »; wall dark cinnamon-brown, 2~2.5 » thick, strongly 
and very sparsely echinulate, the echinulations colorless, 2—2.5 4 long, the pores 2, equatorial. 
III. Telia hypophyllous, crowded about the uredinia on more or less irregular, light- 
colored areas, oval or oblong, 0.3-1 mm. long, long covered by the overarching tissue, whitish 
or pale-brown, somewhat pulverulent; teliospores oblong or oblong-clavate, 18-26 by 35-48 p, 
rounded above, rounded or slightly narrowed below, somewhat constricted at septum; wall 
colorless, uniform in thickness, 1.5-2.5 4, smooth; pedicel colorless, about half length of 
spore, 13-15 « wide.
