Ceucospora chamjecrista, Ell & Kellerman.—On leaves and pods 
of Cassia chamcecvista. Manhattan, Kans., October, 1887, Kellerman <fc 
Swingle (1126). Ilypophyllous; hyphse loosely fasciculate, coarse, pale 
brown, sparingly septate, 50—70 x 5-6 /'-, abruptly bent and subnodulose 
above; spots none, tufts effused and soon spreading over the entire lower 
surface of the leaf, which then assumes a brown, scorched look; conidia 
subcylindrical, smoky-hyaline, 1—3-septate and sometimes constricted at 
the septa, 35—55 x 5—7 /'-. 
Cercospora paciiypus, E. & E. Journ. Mycol., Ill, p. 104.—A 
form of what appears to be this species has been found in Kansas (Keller¬ 
man & Swingle, No. 112) on leaves of Helianthus lenticularis , having the 
conidia 1—3-septate, the tufts of hyphse rather larger and longer and the 
pallid-yellowish spots at first distinctly visible on both sides of the leaf. 
The following may also be added to the list of North American

Cercospora lateritia, Ell. & Halsted.—On living leaves of Sam- 
bncus pubens. Ames, Iowa, September, 1887, B. D. Halsted. Hypo- 
phyllous, in indefinite, pale, brick-colored patches, which soon become 
confluent, covering the greater part of the lower surface of the leaf, 
which is variegated above with brownish spots, which become more or 
less conliuent and darker and finally nearly black; hyphse coarse, 50—70 
x 8—10 /'-, branching and septate, arising in spreading tufts through the 
stomata of the leaf and more or less interwoven and matted together; 
conidia mostly cylindrical and straight, with ends obtuse, 2—6-septate 
and generally constricted at the septa, reddish-brown, 50—80 x 6—8 p, 
occasionally longer (100 :>■ or over) and then attenuated above. This is 
closely allied to C. ferruginea , Fckl., and C. racemosa , E. & M., but is a 
coarser species than either of these, though in color and general appear¬ 
ance it much resembles the latter. 
Cercospora Lycii, Ell. & Halsted.—On Lgcium vulgare. Ames", 
Iowa, September, 1887, B. D. Halsted. Spots amphigenous, yellowish- 
brown, becoming thin and white in the center, 2—4 millim. in diameter, 
discoid, with a definite, raised margin; hyphse mostly epipliyllous, yel¬ 
lowish-brown, paler above, septate, 80—120 x 4 nearly straight, but 
more or less shouldered and toothed above, forming erect tufts arising 
from a small tubercular base; conidia slender, 80—150 x about 4 /*, hyaline, 
continuous or faintly 5—4 or more septate.
