O. Pycnia amphigenous, in oval groups 1-2 mm. long, usually surrounded by or among the 
aecia, deep-seated and often erumpent, globoid, about 200 w in diameter, honey-yellow; ostiolar 
filaments compact, about 35 u long. 
I. Aecia amphigenous, gregarious, in small roundish or oval groups 1-4 mm. long on 
brownish spots; peridium white, delicate, deeply lacerate, recurved, soon falling away, leaving 
the ruptured epidermis conspicuous; peridial cells terete or slightly rhomboidal in longitudinal 
section, 16-27 by 40-60 y, the outer wall coarsely verrucose-striate, 4-5 y thick, the inner wall 
2-3» thick, rather sparsely and coarsely verrucose; aeciospores globoid, broadly ellipsoid 
or obovoid, 23-27 by 24-34 u; wall colorless, 2-3 » thick, finely verrucose. 
III. Telia amphigenous, scattered or arising about or within the aecia, oval or oblong, 
rupturing by a longitudinal slit, rather tardily naked, blackish, slightly pulverulent; telio- 
spores ellipsoid or oblong, 27~34 by 42-58 yu, very slightly or not constricted at septum, usually 
rounded at both ends, occasionally truncate above and narrowed below; wall blackish when 
mature, rather uniformly 2.5-3.5 » thick, occasionally thickened 5 « above, very coarsely and 
prominently verrucose; pedicel hyaline, fragile, up to length of spore. 
Urediniospores occurring sparingly in the telia, broadly ellipsoid or obovoid, 27-35 by 
32-42 »; wall golden-yellow or cinnamon-brown, about 1.5 thick, finely and moderately 
verrucose-echinulate, the pores 12-15, scattered.

O. Pycnia amphigenous, crowded in small orbicular groups, honey-yellow, deep-seated 
in the tissues, depressed-globoid, 160-200 by 130 y; ostiolar filaments rarely protruding above 
the epidermis. 
J. Aecia amphigenous, gregarious, in orbicular or oval groups 1-5 mm. long, often en- 
circling the pycnia, prominent, cylindric, about 0.5 mm. high; peridium colorless, erect, the 
margin finely erose or somewhat lacerate; peridial cells slightly rhomboidal in longitudinal 
section, 25-32 by 32-40 yn, the outer wall thick, 10-14 y, conspicuously striate, the inner wall 
thinner, 6-8 yu, rather coarsely verrucose; aeciospores globoid, 18-23 by 24-33 4; wall colorless, 
moderately thick, 2-2.5 », closely and distinctly verrucose. 
III. Telia amphigenous, scattered, oblong, 1-3 mm. long, tardily naked, chestnut-brown, 
somewhat pulverulent, ruptured epidermis membranous, conspicuous; teliospores broadly 
ellipsoid, angular, 20-30 by 35-40 u, cells often unequal in size and shape, rounded or oblique 
at both ends, very slightly constricted at septum; wall dark cinnamon-brown, of uniform 
thickness, 1.5~—2 y, finely rugose, with a few prominent irregular longitudinal ridges; pedicel 
hyaline, delicate, short, rarely as long as spore.
