III. Sori scattered or circinate, mostly hypophyllous, small 
(7% mm.), naked, nearly black. Teleutospores obovate or ellipti- 
cal, becoming chestnut-brown, 22—28%18-—22 », epispore smooth, 
rather thick, moderately thickened at the rounded apex. Pedicels 
35-50 » long, stout, hyaline. There was no indication of any

UROMYCES CARICINA E. & E. 
On leaves or culms of Carex scoparia, Alcove, N. Y., July, 
1893 (C. L. Shear, No. 81). I. & III. 
_ Sori scattered, oblong, %-1 mm. long by about % mm. wide, 
covered by yellowish epidermis, not confluent. Uredospores 
sparingly mixed with the teleutospores in the same sori, ovate or 
elliptical, pale, tuberculo-echinulate, 20-22X14-16. Teleuto- 
spores obovate, pale below, rounded at the apex, or often with a 
distinct hyaline papilla, epispore smooth, strongly thickened and 
dark colored at the apex, 19-23+14-16. Pedicels yellowish, 
about as long as the spores.

I. Aecidium on the slightly swollen stems and _ petioles. 
Erumpent, closed at first, soon open and cup-shaped, about 
mm. diam., thin, margin toothed. Spores ovate or subglobose, 
15-20 » diam., yellowish, epispore slightly echinulate, ampht- 
genous. 
Il. Uredo sori small, pale cinnamon color, y%-Y% mm. diam., 
naked above. Uredospores obovate or globose, 15—22 / in the 
longer diam., rather closely echinulate, hyaline, becoming pale 
brown. 
III. Teleutospores in larger (1 mm.) nearly black naked 
sori, elliptical, 22~-3515—20 », pale chestnut brown, rounded at 
each end, contents granular, scarcely constricted at the septum, 
epispore scarcely thickened at the apex, and when examined dry, 
under a high power, covered with a network of raised lines. 
Pedicels very short, almost wanting. : 
Differs from the other related species on Ziare//a and Sasifrag@ 
in the presence of Uredo and also in other particulars.
