row raised border, hyphae tufted (25-30x4/^), crooked and subden- 
tate above, continuous, brown; conidia clavate-cylindric, multisep- 
tate, 75-100x3-4//. The spots are at first purplish, with a purple 
shaded border but soon whiten out. . 
On leaves oi Isanthtis, Manhattan, Ks. Aug. No. 610. 
Cercospora tuberosa. — Hypophyllous, on spots (.75-5*'"**) ^t 
first gray and imperfectly defined, but at length dirty brown and of 
irregular outline, angular, elongated and partly limited by the vein- 
lets of the leaf, hyphse arising from' a small tubercular base, nearly 
straight and more or less toothed above, septate, brown, 35-45 M/^! 
conidia subcylindric, slightly tapering downwards, subfuscous, 5-10- 
septate, 80-110x3.5-4//. 
The spots are darker and more distinctly defined on the upper 
side of the leaf. This differs from the preceding chiefly in the char- 
acter of the spots. 
On leaves of Apios tuberosa. No. 613. 
Cercospora oculata, — Mostly epiphyllous, on dirty brown spots 
(•25-75''"'*), with a definite, slightly raised, narrow, darker border; 
hyphoe casspitose, short (25-30x4//) obtuse, simple, brown, continuous 
entire or sHghtly denticulate and obtuse above; conidia at first oblong 
and i-septat'e, 20-30// long, at length attenuated below and becoming 
30-60x3-4// and faintly 3-septate. 
The spots are often concentrically wrinkled and sometimes con- 
fluent, forming patches 2-3*^"^ across. This differs from C Vernoni^, 
E. & K., in the different character of the spots, as well as'in its shorter 
and less distinctly septate conidia.

CEROCpSPORA Teucrii.— Epiphyllous, on brown (mostly i-2"'"'-) 
spots which soon become dirty white, with dark or purple shaded 
border; hyphae tufted, brown, crooked and sub-denticulate above, 
7.5-120x3-4//, faintly septate.

Notes on Corema Conradii. 
In July, 1879 I lound Corema Conradii gxow'mg quite abundantly 
at Grand Lake, Nova Scotia. It was limited, however, to a bare 
promontory on the eastern shore of the lake, and was associated with 
Myrica Gale.

To Mr. Redfield's interesting and comprehensive list of 
localities of Corema Conradii, in the last number of the Bulletin, I 
have one addition to make. On the summit of Blue Mountain, just 
back of Camden, Maine, perhaps eight hundred feet in height, and 
within a half hour's climb from the village, I have found several large 
patches of this interesting species. The dates of flowering are noted 
in my herbarium as Mav i8th, 1859, and May 2nd, t86o.
