later abundantly and irregularly branched, the branches usually 
straight and slightly tapering upward, terminated by a small cluster of 
oval-oblong 3-5 by 1 2-2J// hyaline conidia. 
Ovularia Carletoni, n. s. On Lactuca , Mitchell County, Kans., 
June, 1886 (M. A. Carleton, 141). Hypophyllous forming patches more 
or less distinctly limited by the veinlets 2-4 millimeters in diameter and 
of a pale yellowish color. The leaf is also marked on the upper side 
with pale yellowish indefinite spots. Hyphse hyaline, 25-35 by 4—5//, with 
offsets or shoulders on the sides marking the points where the conidia 
were attached, closely aggregated in minute tuberculiform masses. 
Conidia oblong-elliptical, hyaline, continuous, 12-15 by 6-7//. 
Ceecospora Bartholomew n. s. On Rhus toxicodendron , Rooks 
County, Kans., September, 1888 (E. Bartholomew, 183 and 248a). Hy¬ 
pophyllous in inconspicuous, indeterminate, smoky-colored, scattered 
or subcontinent patches. Hyphae fasciculate, straight or subundulate, 
nucleate, continuous or sparingly septate, reddish brown (under the 
microscope) 20-40 (mostly 24-34) by 4-6/* sometimes branched from 
near the base, tips entire or subdentate. Conidia nearly hyaline, vary¬ 
ing from oblong to slender obclavate and from 20-120// long and 2£-3// 
wide,nucleate becoming 3-8-septate, the shorter ones straight, the longer 
ones a little curved. This is very different from C. toxicodendri , Ell. 
Macrospoeium baccatum, n. s. On old nuts of zEsculus arguta , 
Manhattan, Kans., March 1888 (Kellerman & Swingle 1239). Forms 
a dark olive thin but compact velvety coat on the nut. Fertile hyphse 
sparingly branched or simple ; torulose, 5-8// in diameter, the joints oc¬ 
casionally swollen at intervals, nucleate. Conidia terminal, composed 
of rather loosely aggregated sub-globose cells, having an irregularly 
lobulated outline, somewhat resembling the fruit of a blackberry, very 
variable in shape and size, 16-40 by 8-27//, usually without pedicels. 
Zignoella diaphana, (C. & E.). Sacc. var gracilis, ii. var. On 
decayed log, Manhattan, Kans., June, 1888 (Kellerman & Swingle 1249). 
The sporidia are acutely elliptical, 3-4-nucleate, hyaline 11-12^ by 5-6//, 
and like those in our specimens of Z. diaphana (although Saccardo, in 
Syll. II, 220, gives the size as 20 by 7£//), but the asci, which are 75-87 
by 6-9//, are larger; and the perithecia, which are mostly 120-240// in 
diameter, and globose-conic or subrostrate, are smaller and more acute. 
Possibly it should be assigned specific instead of varietal rank.
