Schizonella subtrifida, n. s. N. A. F. 2266. Tn flowering beads 
of Cirsium ochrocentrum. Wet Mountain Valley, Colo., July 25, 1888* 
Rev. C. H. Demetrio. No. 162. Spores violet or purple brown, subglo- 
bose or elliptical, soon becoming uniseptate and finally separating into 
two hemispherical segments. Epispore strongly tubercular-roughened, 
12-20 by 12-16,a. Occasionally spores are seen with a triradiate septum 
much the same as in the spores of Triphragmium clavellosum , Berk., 
and in this case the spore separates into three parts iusteadof two, but 
the great majority of the spores are bifid. The fungus occupies the whole 
interior of the flowering heads, which become hollow and abortive. 
Ustilago diplospora, ii. s. In ovaries of Panicum sanguinale , 
Holly Springs, Miss., September 1890. Tracy No. 1551. Mass of 
spores dark brown. Spores of two kinds, the smaller ones globose, 
rough, brown, 7-8,a diameter, the larger ones 12-15,a smooth, globose, 
pale, nearly hyaline. 
Ustilago Montaniensis, ii, s. On Muhlenbergia glomerata , Sand 
Coulee, Mont., December 1887. Leg. Anderson. In the inflorescence 
which is rendered abortive and remains inclosed in the sheaths of the 
leaves. Mass of spores dark brown, nearly black. Spores subglobose, 
10-14,a diameter or oblong or ovate oblong, 12-16 by 10-12,a epispore 
subtubercuiose-reticulated, pale-brown. 
.Ecidium micropuncTUM, ii. s. On Castilleia from Pine Ridge, 
Nebr., July, 1890. Prof. T. A. Williams. Hlcidia gregarious in oblong 
groups or patches 3-5 mm long and 2-3 mm wide, small sunk in the 
substance of the leaf, which is only slightly thickened, border narrow, 
erect, sublacerate. Spores subglobose or suboblong, more or less an¬ 
gular, smooth, 18-20,a in the longer diameter, orange yellow, approach¬ 
ing orange red. 
JEcidium eurotias, ii. s. On Eurotia Janata , Helena, Mont., Rev. 
F. D. Kelsey, June 1889, Com. F. W. Anderson. No.514. JEcidia hypo - 
phyllous , arranged along each side of the midrib, short cylindrical, about 
| mra high and J mlu broad, with a thin, suberect, sublacerated margin. 
Spores orange-yellow, subglobose, smooth, 15-20,a diameter. 
TJromyces scaber,ii.s. III. On leaves of some grass. Swift Creek, 
Custer County, Colo., October 1S88. Cockerell, No. 62. Sori elliptical, 
bare, dark chestnut color, nearly black, £-l mm long by i-| mni wide, pul- 
vinate, gregarious or subconfluent. Spores globose 20-22,a or elliptical 
22-25 by 20-22,a, densely echinate-scabrous, epispore scarcely thickened 
at the apex, pedicels subequal, hyaline, 40-50 by 4. 
Puccinia arabicola., ii. s. On Arabis sp. Ottawa, Canada. Dr. 
J. Macoun, I and III. 
I. iEcidia amphigenous, collected in patches or groups 2-4 mra across, 
hemispheric and closed at first, then open, small, shallow, margin slightly 
spreading and minutely denticulate. The spores having mostly disap¬ 
peared from the rather scanty specimens, we can not now accurately 
describe them. 
III. Sori amphigenous,scattered, small, black-brown, covered at first
