80. ERYTHEA. 
58 x 38u, the single-celled from 23 x 25 to 45 x 33 and even 
more. The two-celled spores are usually rounded at both 
ends and slightly constricted at the septum. Membrane 
verrucose, not thickened at the apex, pedicels short and 
deciduous. 
On Borrichia frutescens. Corpus Christi, Texas, April, 
1894, leg. A. A. Heller. 
Puccinia graminella (Speg.), D. & H. Spots yellow or 
purplish. Aicidia and teleutospores epiphyllous. Aicidia 
arranged to oblong groups or lineally extending along the 
veins of the leaves. Pseudoperidia persistent, irregularly 
bursting, composed of oblong cells. AXicidiospores elliptical 
or ovoid, 21-29 x 18-21, epispore thick, colorless, verrucose 
or striolate. Teleutospores: sori elongated, pulvinate, dark 
brown; spores hardly constricted at the septum, thickened 
above, smooth, brown, 35-48 x 22-28u. Pedicels stout, 
longer than the spores.

1894, leg. Holway and Blasdale 
This curious fungus bears only ecidia and teleutospores 
on the same host plant and both often from the same 
mycelium. The ecidial stage has been described by Spe- 
gazzini from Buenos Ayres under the name Acidium 
g) llum; the teleutospore stage was hitherto unknown. 
Puccinia Panici, D. Uredo: spots yellowish, indefinite; 
sori epiphyllous, very minute, oblong, surrounded by the 
burst epidermis, brown. Uredospores broadly elliptical 
or globose, densely echinulate, brown, 25-31 x 25-294. Tel- 
eutospores: sori epiphyllous, pulvinate, black, small, oblong 
or linear. Teleutospores oblong or clavate, apex thickened, 
rounded or conical, base rounded or attenuated, central con- 
striction slight, 29-48 x 15-21, brown. Pedicels of different 
length, on an average as long as the spores. 
On Panicum virgatum. 
This is the well known, widely spread Puccinia on 
Panicum virgatum, which has been united hitherto with
