O. Pycnia amphigenous, few in groups surrounded by telia, or entirely wanting, notice- 
able, honey-yellow turning to dark-brown, globoid, 95-110 4 in diameter; ostiolar filaments 
forming a column 80-110 » high. 
III. Telia hypophyllous or caulicolous, round, 0.5-1 mm. in diameter, becoming confluent, 
and often covering considerable areas, firm, pulvinate, early naked, blackish-brown, becoming 
cinereous from germination, ruptured epidermis not conspicuous; teliospores ellipsoid, oblong, 
or obovate, 20-28 by 38-75 pn, rounded or obtuse above, rounded or narrowed below, not 
or slightly constricted at septum; wall golden- or light cinnamon-brown, 2-4 » thick, thickened 
above, 5-10 4, smooth} pedicel colorless, firm, persistent, up to 200 » long. 
This species is correlated with the heteroecious Allodus graminella (Speg.) Arth. and 
the autoecious Allodus interveniens (Peck) Bethel, the morphological characters of like stages 
in the three species being similar or identical, and there being a significant correspondence 
in hosts. This agreement doubtless indicates 2 common origin for the three species.
