Epiphyllous, on pale yellowish, indefinite spots at first, but 
soon spreading over the entire surface of the leaf, forming a 
thin, mouse-colored stratum, the spots now being scarcely recog¬ 
nizable. Hyphae in dense tufts, 15-20x3 fx, subnodulose, contin¬ 
uous, or faintly septate, obtuse at the apex, subolivaceous, Conidia 
slender, obclavate, with a slight oblivaceous tinge, slightly curved, 
50-80x2^-3 n , faintly 3-5-septate. 
Cercospora sessilis E. & E.—On (dead) ? leaves of Popu- 
lus monolifera. Beloit, Ala. Sept. 1901. 
Epiphyllous; conidia fasciculate, sessile (or nearly so) on 
a minute, sphaeriform base, curved or undulate, 20-60x3 /x, oliva¬ 
ceous, guttulate, becoming 3-or more-septate. 
On the same leaves are many small grayish-white spots but. 
the Cerocospora is on the dark colored part of the leaf and not 
on the spots though it may partly overrun some of them. 
C. populina E. & E. (Jour. Mycol. 3:20) is on definite spots 
and is different from this. 
Cercospora graticlae E. & E.—On Gratiola pilosa. 
Hyphae cespitose, short (25-35x3 /a), continuous, brown* 
somewhat crisped and toothed above, tufts effused, forming an 
olivaceous layer over the lower side of the leaves, but not on 
any spots. Conidia cylindrical, olivaceous, nucleate, becoming 
about 5-septate, 60-75x3^-4 / 1. 
Cercospora hydrangeae E. & E.—On leaves of Hydrangea 
cult. 
Spots amphigenous, subangular, more or less confluent s© 
as to cover a greater part of the leaf, rusty-brown becoming 
dark brown. The brown spots become pale silver gray in the 
center on both sides of the leaf and on these gray spots the 
tufts of hyphae are sparingly scattered. Hyphae nodulose and 
geniculate, brown, simple, continuous or 1-2-septate below, sub- 
dentate at the tips, 40-60x3^-4 fx. Conidia slender obclavate, 
hyaline, faintly septate towards the thick end, 60-80x3^-4 /x. 
Cercospora oxydendri E. & E.—On leaves of Oxydendrum 
arboreum. 
Leaves at first mottled with dull red, more distinctly so 
above, the red areas bounded at first by the veinlets, soon con¬ 
fluent over a great part of the leaf, here and there forming 
distinct, indefinitely limited spots of a deep-brown color, one 
or more centimetres in extent. Hyphae tufted, short, the tufts 
becoming almost black, especially above, of a lighter color but 
not so abundant below. Conidia slender, obclavate-cylindrical, 
3-5-septate, subolivaceous, 50-75x3-4 /x, mostly a little curved. 
Cercospora brachypus E. & E.—On leaves of Vitis rotund- 
ifolia.
