mens on Andropogon Virginicus , described by Dr. Winter in Bull. Torr. 
Club, X p. 7, and distributed iu X. A. F., 1099, in its more regular- 
shaped spores, with a thicker epispore and its larger spore glomerules 
subglobose, 35-150 p, or oblong, 100-200 by 75-80 p. The cylindrical 
mass of spores, also with an elongated bundle of libers (the remains of 
the enveloping sheath)*?, is inclosed in a light-colored membranaceous 
sack, which protrudes above, while in the typical form this sack is less 
distinct and is entirely concealed. 
Sorosporium Eyerhartii, n. s. In florets of Andropogon Vir¬ 
ginicus. Xewfield, X. J., October (X. A. F., 2265 b.). Glomerules com¬ 
pact, opaque, 50-120/q iu diameter, globose or oblong, composed of 100- 
300, or more closely-compacted spores, which do not easily separate 
and vary from subhyaline to brown and from subglobose 8-10 p in 
diameter to oblong, 10-12 by 8-10/q with a nearly smooth epispore of 
medium thickness. The t-ips of the glumes in the affected florets be. 
come bleached, and open in a bifid manner, the lobes more or less 
reflexed, allowing the subcylindrical mass of spores to protrude. This 
differs from 8. Ellisii , Winter in its smaller spores, more compact glom¬ 
erules, and in attacking single florets instead of involving the entire 
inflorescence. 
Didymosphasria denudata, n. s. On bark of dry dead oak limbs 
from which the epidermis had fallen off. Xewfield, X. J., March, 1889. 
Perithecia scattered, ovate, suberumpent, minute (one-quarter milli¬ 
meter), with comparatively thick membranaceous walls, the erumpent 
apex (about one-third part) roughish, black, with a papilliform ostio- 
lum. Asci cylindrical, about 50 by 7/q abruptly contracted below into 
a short stipe-like base. Sporidia 1-seriate, elliptical, 1-septate, brown, 
6-7 by 4 p. This differs from B. cupula , E. & E., in its perithecia not 
collapsing and smaller, and in its smaller sporidia and shorter asci. It 
is found on the upper exposed side of the limb which is usually more 
or less bleached. 
Opiiionectria Eyerhartii, n. s. On old Biatrype stigma and on 
the decaying bark of oak limbs. Xewfield, X. J., January, 1889. Gre¬ 
garious, Perithecia ovate-globose, about one-sixth millimeter in diame¬ 
ter; granular-pruinose, except the rather acutely papilliform ostiolum 
dull dirty-yellow. Asci oblong-cylindrical, 75-80 by 12-14 p, with 
rather indistinct parapliyses. Sporidia crowded-biseriate, fusoid, yel¬ 
lowish-hyaline, nucleate becoming faintly multiseptate, straight w r hile 
lying in the asci, curved when free, 35-50 p long and 3-3 \p thick in 
the middle, gradually tapering towards each end. 
Glceosporium paludosum, n. s. On leaves of Peltandra Virginica. 
Virginia, August, 1889. D. G. Fairchild ; Wilmington, Del., October, 
1889. A. Commons, Xo. 977. Spots amphigenous, orbicular, or ellip¬ 
tical, J-l centimeter in diameter or by confluence larger, dirty brown, 
subzonate; margin darker and subindefinite. Acervuli minute (65-75yu), 
mostly erumpent above. Spores oblong, granular, 18-22 by 6-7 p.
