obscure beneath; hyphse in sparsely-scattered tufts, brown, septate, more 
or less bent and subdenticulate above, about 100 x 3 /•*; conidia hyaline, 
slender, rnultiseptate, mostly recurved above, very long (250—300 x 3 p). 
Cercospora LIelianthi, E. & E., has also been found by W. T. 
Swingle on H. rigidus (1085) and H. doronicoides (1073) differing from the 
Missouri specimens (Journ. Mycol., Ill, p. 20) in being amphigenous 
and having the conidia longer (100—150 
Cercospora Menispermi, Ell. & Holway.—On living leaves of M. 
Canadensis. Decorah, Iowa, June, also at Manhattan, Kans., July, 1887, 
by W. T. Swingle. Hypopliyllous, appearing at first on small, indefi¬ 
nitely-limited, dark brown spots, which finally become orbicular (3—5 
millim. in diameter), mostly concave below and more or less confluent, so 
that the leaf appears more or less blackened and dead; hypha3 nearly 
straight, pale brown, mostly continuous, 75—80 x I p, with a few shoul¬ 
der-like notches above, forming tufts arising from a subspherical, tuber¬ 
cular base about 35 a in diameter; conidia obclavate, 40—60 x 5—7/*, pale 
brown, nucleate, becoming 3—5-septate. Many of the conidia are much 
shorter, obovate or oblong elliptical (15—25 x 5—7 ,"-), 1—3-septate, resem¬ 
bling the conidia of a Cladosporium. 
Cercospora Callas, Pk. & Clinton.--This has been sent by Mr. 
Commons from Delaware, on Peltandra Virginica, agreeing well with 
authentic specimens on Cnlla palustris. In Journ. Mycol., I, p. 22, the 
hyphae are said to be ‘■short.” In the specimens from Prof. Peck, they 
are 60—90 x 6 /'-, and in the Delaware specimens, they are 70—110 p long. 
Cercospora tabacina, E. & E.—On Eudbedda triloba. Ames, 
Iowa, Dr. 13. D. Halsted. Mostly liypophyllous, forming tobacco-brown 
patches limited by the veinlets of the leaf; hyphae tufted (tufts sub¬ 
effused), brown, slender, septate, abruptly bent, often with one or more 
rudimentary branches above, 100—150 x 4 /'-; conidia with a brownish 
tint, varying in size and shape from oblong, 25 x 4—5 P and one-septate to 
obclavate, 50—75 x 4—5 /'-, three-septate. This differs from Cercospora 
HeUanthi , E. & E., in its tobacco-brown color and in being limited by 
the veinlets. 
Cercospora Daleae, Ell & Kellerman.—On dead stems of Dalea 
laxijlora. Kansas, July, 1887, Kellerman & Swingle (954). Hyphae sim¬ 
ple, brownish, straight, subdenticulate above, 25—30 x 4—5 p, forming 
dense, sphaeriaeform tufts subseriately arranged or gregarious in elon¬ 
gated patches; conidia obclavate-cylindrical, brownish, 1—2-septate, 
30—40 x 3—4 p. The part of the stem occupied by the fungus becomes 
cinereous-brown. 
Cercospora Asclepiadoras, Ell. & Kellerman.—On fallen leaves 
of Asclepiodora viridis. Kansas, July, 1887, Kellerman & Swungle, 954 bis. 
Amphigenous; hyphae simple, dark brown, short (15—25 /•*), fasciculate in 
densely crowded tufts, which form nearly black patches, indefinitely 
limited or bounded partly by the veinlets; conidia sublanceolate, brown, 
rnultiseptate, 70—80 x 4—5 p.
