SeptoriA convolvuli, Desm. Prof. Hitchcock sends this from 
Iowa on Calystegia sepium. It is distinguished from #. calystegice , Desm. 
and 8. flagellar is, E. & E. by its more numerous perithecia and larger 
spots, and from the latter also by its shorter (20-35//) sporules. 
Spii^eronemella carnea, n. s. On ash bark, Lake Skaneateles, 
New York, July, 1872. Rev. J. L. Zabriskie, 119. Perithecia gre¬ 
garious, erumpent, flesh-colored, subulate, 2 millimeters long, swollen 
at the base, which contains the sporigenous nucleus. Sporules oblong, 
hyaline, continuous, about 15 by 4//, rounded at the ends. 
Spii^ronemella ROSiE, n. s. On dead twigs and old calyx tubes 
of Rosa lucida , Newfield, N. J., June, 1889. Perithecia erumpent, 
membranaceous, ovate, yellowish, becoming black, about £ millimeter 
in diameter ; narrowed above into a short, cylindrical, membranaceous, 
pale ostiolum, crowned with spherical yellow globule of exuded, nar¬ 
row, elliptical, hyaline, continuous, 44-5J by 24-3// sporules. The peri¬ 
thecia are loosely bordered by the ruptured epidermis and white inside 
from the mass of sporules. This approaches Cytispora , but the perithe¬ 
cia are Simple. 
ASTERINULA nov. gen. of SPHiEROPSIDEiE Pam. LEFTOSTRO- 
MACEJE. 
Perithecia dimidiate, scutelliform, submembranaceous, radiate-cel¬ 
lulose; sporules ovoid or oblong, 1-septate, hyaline. Differs from Lep- 
tothyrium in its uniseptate sporules, from Asterina in the absence of 
asci, and from Ascochyta in its superficial perithecia. 
Asterinula Langloisii, n. s. On living leaves of Magnolia grandi- 
flora , Louisiana, January, 1889. Rev. A. B. Langlois, 1656. Hy- 
pophyllous. Perithecia scattered or gregarious, not on any definite 
spots, dimidiate, superficial, radiate, cellulose, pierced above, 100-112// 
in diameter mostly with a short fringe of brown mycelium around the 
margin. Sporules oblong or obovate-oblong 2-nucleate, becoming 
1- septate, hyaline, 18-22 by 7-8//, ends rounded and obtuse. Proba¬ 
bly the spermogonial stage of some Asterina. 
Diplodina ramulorum, n. s. On bleached stems of Smilax and 
Lycium , Newfield, N. J. Perithecia subcuticular, black, minute, gre¬ 
garious. Sporules oblong, elliptical, smoky hyaline, 1-septate, 5-8 by 
2- 3//. 
Discula xantiioxyli, n. s. On dead stems of Xanthoxylum , St. 
Martinsville, La., January, 1889. Rev. A. B. Langlois, 1000. Perithe¬ 
cia gregarious, on bleached spots 2-3 centimeters long by J centi¬ 
meter broad, subdiscoid, about 150// in diameter, of rather coarse 
cellular texture, with a small circular opening above. Immediately 
around this opening the perithecium is more compact and nearly opaque, 
but around this dark center it is thinner and translucent. Sporules 
abundant, oblong-cylindrical, hyaline, continuous, 12-20 by 3-3J//, 
arising directly from the cells of the proligerous layer, which are some-
