[Von. Ill, No. 5, 
Tilletia cerebrina, E. & E.—In ovaries of Beschampsia ccespitosa 
has globose, dark brown spores, 22—28 P in diam., outer hyaline coat 
about 21 p thick, bareJy covering the projecting edges of the thick-walled, 
irregular, subcerebriform reticulations Differs from all the three pre¬ 
ceding species in its larger spores. 
Ustilago Mexicana, E. & E.—In the ovaries of some undetermin¬ 
ed species of Muhlenbergia . Collected on the mountains near Bato- 
pilis, Mexico (alt., 8,850 ft.), by Dr. E. Palmer. Spores black or 
violet-black, smooth, globose, 5—6 p or subelongated, 6—8 x 5 p. 
ISTearly every ovary on the affected plants is filled with the dusty mass 
of spores. 
Ustilago Uniol^e, E. & E.—In ovaries of Uniola gracilis , from 
Texas. Spores subglobose, echinulate-tuberculose,' 7—10 P , of a dull 
black color seen in mass. The affected ovaries are considerably 
swollen. 
Ustilago viridis, E. & E.—On Setaria , Louisiana. Rev. A. B. 
Langlois, Xo. 56. Forming a yellow-green coating on the outside of the 
seeds, which are swollen and become white and soft within ; spores 
globose or nearly so, 4—5 P , rough warted. 
Sorosporium consanguineum, E. & E.—In ovaries of Aristicla 
Busbyi , Scribner. Collected in Northern Arizona by Mr. Rusby. Spore 
masses globose or subelongated, 50—70 p in diam., composed of small 
(6—8 p), polygonal spores with the epispore smooth or nearly so. Differs 
from S. Ellisii , Winter, in its smaller, smooth spores. 
Uromyces Aristide, E. & E.—On leaves of Aristida , New Mexico. 
III. Sori linear, 1—2 millim. long,naked (when mature), dark ferrugin¬ 
ous-brown ; spores loosely compacted in the sori, elliptical or obovate, 
25—35 x 18—22 P , smooth, yellowish-brown, on long (80—100 /■*), stout but 
deciduous pedicels, epispore not distinctly thickened above. Differs 
from U. Poce , Rabh., and from 17. Dactylidis, Otth., in its elongated sori 
and larger spores. 
Puccinia subcircinata, E. & E. (N. A. F., 1,840.)—On living 
leaves of Senecio triangularis , Mt. Paddo, Wash. Terr., August, 1885. 
W. N. Suksdorf, No. 197, I and III. 
I. Aecidia gregarious, mostly surrounded by the sori of the teleuto- 
spores, mostly hvpophyllous, shallow, about one half millim. in diam., 
with a spreading, toothed margin; spores globose, 12—15 p or sub¬ 
elliptical, 20 x 12—15 P, or subangular or otherwise irregular. 
III. Mostly hypophyllous and arranged in a ring around the clusters 
of secidia, but also more or less scattered and forming groups unaccom¬ 
panied by aecidia or extending down on the petiole of the leaf ; sori sub- 
liemispherical, lead-color, about one half millim. in diam., opening above 
in a circumscissile manner, with a distinct round opening, as if the top 
had been cut away, and discharging through this opening the abundant
