differs only in its rather shorter spores, -which are also more distinctly 
thickened at one end. In both they are 3-septate. 
Glceosporittm (Septoglceum) ampelopsidis, n. s. On fading leaves 
of Ampelopsis quinquefolia , Racine, Wis., September, 1888, Dr. J. J. 
Davis, 09. Spots amphigenous, angular, limited by the veinlets of 
the leaf, 2-3 millimeters in diameter, greenish. Acervuli erumpent on 
both sides of the leaf, prominent. Spores clavate-cylindrieal, 5-9-sep- 
tate, 30-35 by 4-44/./. 
Glceosporium lagenariijm, Pass. var. Musarum, E. & E. On 
banana rind, Lincoln, Nebr., Roseoe Pound, 23, does not differ es¬ 
sentially from the forms on various species of Cucurbitacece. A folii- 
colous form of this species has proved very destructive around New- 
field, N. J., this year on water-melon and musk-melon vines. 
Cylindrosporium? oculatum, n. s. On leaves of Populus monil- 
ifera , Put-in-Bay, Ohio, August, 1888, Dr. J. J. Davis, 14. Spots 
amphigenous, round, 3-5 millimeters in diameter, grayish white, with a 
darker margin and a narrow raised border. Acervuli innate, amphig¬ 
enous, yellowish (finally blackish), rather large (| millimeter). Spores 
clavate-cylindrical, curved, 30-50 by 3// nucleate (becoming 3 or more 
septate). 
Cyxindrosporitjm clematidis, E. & E. J. M. Ill, p. 22. Mr. 
Galloway sends some leaves of Clematis Jackmanii collected at Geneva, 
K. Y., June 20, 1889, in which the tubercular masses of exuded spores 
are black , but the spores themselves are hyaline as in the original speci¬ 
men on C. Virginiana. In the Geneva specimen the spots are less dis¬ 
tinct and definite, and the acervuli are not confined to the spots, thus 
differing considerably from the original description. It may, however, 
be doubted whether the specimens on C. Jackmanii are specifically dis¬ 
tinct, and we have for the present at least placed them as a variety, C. 
clematidis, E. & E., var. Jackmanii. 
Cylindrosporium viridis, n. s. On living leaves of Fraxinus viri¬ 
dis, St. Martinsville, La., May, 1889. Langlois, 1712. Spots (on the 
upper side of the leaf) numerous, dark purple, suborbicular, 3-4 milli¬ 
meters in diameter, with a subindefinite margin and a small (1 milli¬ 
meter or less) rusty-brown center. On the lower surface of the leaf the 
purple color is entirely wanting, only dirty brown 1-2 millimeter subin¬ 
definite spots opposite the center of those on the other side. Acervuli 
innate, 3-6, in or near the center of the spots, prominent below, but 
opening above and discharging snow white heaps of cylindrical fusoid, 
30-35 by 2£//, nucleate spores curved nearly to a semicircle. The 
measurement is from tip to tip as the spores lie curved. Readily distin¬ 
guished from C. fraxini , E. & K., by the purple spots and shorter 
spores. What appears to be the same, but without fruit, has also been 
sent from Ohio (Morgan, 405).
