275 
fluent for l cm or more long, so very abundant as to blacken the leaf, 
hypopliyllous, black, at first covered by the epidermis, but soon bare, 
not prominent. Teleutospores ovate or elliptical, 25-50 by 15-22//, sessile 
or nearly so, moderately constricted at the septum, apex rounded or 
flattened, sometimes obliquely flattened, strongly thickened, but not 
papillate, darker colored and mostly shorter and broader than in 
P. rubigo-vera. The sori are mostly surrounded by parapliyses. The 
habit also is different. 
Puccinia subcoleapsa n. sp.—Ow leaves and stems of some plant 
of the order Asclcpiadacccc , collected in South America by Thomas H. 
Morong. (Communicated by Mrs. E. G. Britton.) (hi.) Sori amphigen- 
ous, hemispherical, chestnut-colored, in diameter, thickly and 
quite evenly scattered over the leaves and stems. Teleutospores ovate, 
elliptical or subglobose, 18-22 by 12-15//, slightly constricted in the mid¬ 
dle,-pale brown. Epispore thin and smooth, often collapsing at the 
apex and sometimes also at the base, causing the two cells to appear as 
if pressed together and giving the spore a subcubical shape. Pedicels 
slender, about GO-75// long, attenuated below and hyaline, slightly 
colored above. Some of the spores are without septa. Differs from 
P. heterospora B. & C. in habit and in its thin-walled, after collapsed 
teleutospores. 
Uredo eriocom^e 7i. sp .—On leaves of Eriocoma cccspitosa. Mohave 
Desert, Kern County, Cal., May, 1892. (D. W. Coquillett.) Sorihypo- 
phyllous, oblong, l-4 ,mn long, pulvinate, soon naked, dark chestnut 
color. Uredospores globose, 20-25// in diameter, or ovate 22-30 by 20- 
25//, hyaline at first, soon becoming chestnut brown. Epispore thick, 
nearly equally so all round, short tubercular-spinulose; pedicels short, 
equal, hyaline. Differs from U. boutelouce Arthur in the absence of 
any spots, the larger sori, and equally thickened epispore. 
Uredo similis n. sp .—On leaves of Lyciurn vulgare. Brookfield, 
Ind., November, 1890. (E. M. Pisher, No. 417.) Sori ampliigenous, 
orbicular, J mm in diameter, yellow, becoming pale brown, scattered, 
flattened, not on spots. Spores obovate, 22-35 by 15-20//, rounded and 
slightly thickened and aculeate above, narrowed and smooth below, 
hyaline, becoming yellow. Pedicels very short. Differs from the Uredo 
of Puccinia lycii Kalcli. in the absence of any spots and in its larger, 
obovate spores. P. afra Winter has uredospores aculeate above and 
smooth below, but oblong and larger. P. tumidipes Pk. also has larger 
uredospores aculeate at both ends. Possibly our Uredo may prove to 
belong to Puccinia globosipes Pk., of which the uredoform is as yet 
unknown. 
Tilletia rugispora n. sp. —In ovaries of Paspalum plicatulum. 
College Station, Brazos County, Tex., 1889. (T. L. Brunk.) Mass of 
spores snuff-gray, filling the ovaries. Spores globose, rather pale 
brown, 15-22// in diameter, tuberculose reticulate, the reticulations 
about 1 p high and 14 u broad. The affected ovaries are scarcely changed 
in outward appearance.
