ited and finally more or less confluent. The leaf is marked above with 
yellowish blotches, .which finally become dark brown. Conidia oblong , 
pale tobacco-brown, nucleate becoming 1-septate, 20-35 by 5-6/*. The- 
mode of growth is like that of C. clavata , Ger. Both this and C. gger 
atoides , E. & E., differ from C. eupatorii , Pk., which is on definite spots. 
Cebcospoba sid-ZECOLA, n. s. On living leaves of Sida spinosa 
St. Martinville, La., December, 1888. Eev. A. B. Langlois, No. 1555. 
Forming smoky black indefinitely effused velutinous patches on the 
under side of the leaf, the upper side remaining green or only slightly 
discolored. Hyphse scarcely tufted, simple, multiseptate, reddish- 
brown (under the microscope), repeatedly shouldered above, slender, 
150-225 by about 4/*. Conidia slender, obclavate, hyaline, granular 
and nucleate, becoming faintly 5-7-septate, 70-100 by 4-5/*. 
Cercosfora fusco-virens, Sacc. Prof. S. M. Tracy finds this at 
Madison, Miss., on Passiflora incarnata with hyphse 40-50 by 4-5/*. 
Conidia 80-120 by 3-4/*. Are the measurements in Sylloge transposed 
It would appear so from these specimens, which agree otherwise with 
Saccardo’s description. 
Sporidesmium insulare, n . s. On bark of living oak. Flatbush, 
L. I., N. Y., December, 1888. Bev. J. L. Zabriskie, 52. Forming small, 
black, scattered patches, about as large as a pin-liead, or more or less 
confluent, bursting through the sterile, granular thallus of some lichen. 
Conidia arising from slender, subhyaline inconspicuous creeping threads, 
at first globose, and as in S. sarcinula , B. & C., marked by two septa 
at right angles, soon enlarged by the addition of a margin of peripheric 
cells and becoming 12-15/* in diameter; when growing beyond this 
size they usually become oblong 25-40 by 15-20/*, more or less irregular 
in shape. The component cells are about 3/* in diameter. We have 
not seen S. epicoccoides , B. & C., from which possibly this is not dis¬ 
tinct. The conidia under the microscope remind one of Gheirospora 
botryospora , Fr. 
Dendrodochium nigrescens, n. s. On bark of Acer negundo . Sand 
Coulee, Cascade County, Mont., November, 1888. F. W. Anderson. 
Sporodochia erumpent, about l mm across, flesh color, becoming nearly 
black. Basidia dichotomously or subverticillately branched, mostly 
curved. Conidia oblong, hyaline, 5-7 by 14-2/*,

Sacidium ulmi-GtALLAE, n. s. Spots none; pseudo-peritheciaoccupy¬ 
ing indefinite blackened portions of the outside of the gall, rather few, 
subgregarious, indistinctly limited, black or dusky black, oval, elliptical 
or irregularly linear, J-2 by J-A mm , at first irregularly inflated, then 
depressed and corrugated, very early splitting nearly the whole length
