[Vol. Ill, No. 2, 
Cercospora ZiziiE, E. & E.—On leaves of Zizia cordata, West 
Chester, Pa. B. M. Everhart. Spots brown, fading to gray in the 
center, nearly round, 3—5 millim. broad; fertile hyphse erect, smoky- 
brown, nearly straight, entire, • csespitose, mostly epiphyllous, 3—8 in 
a tuft, 50—GO x 6—7 y; conidia hyaline, cylindric-clavate, multiseptate, 
100—130 x 4 IK 
Cercospora Hy'drocotyles, E. & E.—On leaves of Hydrocotyle 
interrupta , Louisiana. Langlois, No. 681. Spots amphigenous, reddish- 
brown, 2—3 millim., definite, convex above, concave beneath; hyphse 
amphigenous, in minute tufts, thickly scattered over the spots and 
giving them a granular appearance, pale brown, short and spreading, 
about 20 x 3 continuous, nearly entire ; conidia subcylindrical, subhy¬ 
aline, 30—40 x 3 y\ nucleate. 
Cercospora Lini, E. & E.—On fading leaves of Linum Vir- 
ginianum, Faulkland, Delaware, August, 1886. A. Commons, No. 248. 
Tufts effused, not on definite spots, affected leaves turning yellow; 
hyphse simple, subolivaceous, continuous, forming small but dense tufts 
35—40 y high; conidia slender, 40—60 x 21—3 y, nucleolate, smoky- 
hyaline, slightly curved, gradually attenated above. 
Note.— We have also received a specimen of Cercospora Nasturtii , 
Pass., from Delaware, collected by Mr. Commons on Sisymbrium offici¬ 
nale. Hyphse tufted, brown, 70—85 x 31—4 y ; conidia 60—75 x 4 />-, 
3-septate or more, on pale, orbicular, rather indefinite spots, 3—4 millim. 
in diam. Specimens of Cercospora Galii , Ell. & Holway, from Delaware, 
on G. pilosum, have the conidia 60—90 x 3 y, nucleolate, but not distinctly 
septate. 
Cercospora Rhamni, Fckl.—Specimens of this species, collected by 
John Hogue at Makanda, Ill., October, 1884, have been sent us by Prof. 
A. B. Seymour. This is distinguished from C. aeruginosa , Ck., by its 
longer hyphse and conidia and its hypophyllous growth. 
Graphium clayisporum, B. & C., with difficulty distinguished from 
Cercospora viticola (Ces.) Sacc., has been received from Maryland, sent 
by Prof. F. Lamson Scribner. 
Cercospora platyspora, Ell. & Holway.—On leaves of Zizia inte¬ 
ger rima, Racine, Wis. Leg. Dr. J. J. Davis, June, 1886. Spots amphig¬ 
enous, small (1—2 millim.), irregular, partly limited by the veinlets, 
wood-colored, brown ; tufts hypophyllous, black, lax, quite thickly scat¬ 
tered over the spots, but not confluent; hyphse rusty brown, entire or 
faintly or sparingly septate, spreading and subundulate, 50—70 x 5—6 y ; 
conidia subhyaline, oblong, granular, with an indistinct septum across 
the middle, mostly 35—40 x 6—7 /•*, ends obtuse. The hyphse often have 
the tips subuncinate-recurved, and mostly have lateral, shoulder-like 
projections, which apparently bear conidia. 
Cercospora Melia^, E. & E.—On living leaves of Melia Azedarach, 
Louisiana, September, 1886 Langlois, No. 791. Spots irregular, sub¬ 
confluent or mostly in groups, small (2 millim.), dirty brownish or 
whitish, with a darker border above, much more indistinct and ill-defined
