KAMULARIA AND CERCOSPORA 
Cercospora coffetcola, 13. & C.— On living coffee leaves. Guate¬ 
mala, Comm. Prof. F. L. Scribner. Spots amphigenous, 2—3 millim. in 
diameter, with a white or at least light-colored center and reddish-brown 
margin; hyphse mostly epiphyllous, tufted on the small tubercular base, 
50—75 x 4 with 2—3 septa, fuscous but also elongated to 100 or even 350 
/'-, nodulose and toothed above; conidia only sparingly observed; the few 
seen were hyaline, 2—4-septate, 75 x 3 !>■ (at the thickest end). 
Cercospora brachiata, E. & E.—On leaves of Amarantus retro - 
flexus. Faulkland, Del., August, 1887, A. Commons. Maculicolous ; 
spots amphigenous, dark brown (darker above), becoming whitish in the 
center, rather indefinitely limited, 3—5 millim. in diameter; hyphse 
amphigenous, tufted on a small tubercular base, pale brown, straight, 
cylindrical, faintly septate, spreading, 100—200x34—4/'-; conidia slender, 
faintly multiseptate. hyaline, often reaching 200 !>■ long and about 3 or 3£ 
:>■ thick below. In the early stage of growth, the tufts of hyphse appear 
like minute, black perithecia thickly scattered over the spots, but when 
the conidia appear, they assume a more effused appearance, like a dark 
gray, velutinous pubescence. The species is allied to C. canescens , E. & M. 
Cercospora obesa, E. & E.—On leaves of Cnicus. Manhattan, 
Ivans., July, 1887, \Y T . T. Swingle. Maculicolous; spots irregular, gray- 
brown, 2—5 millim. in diameter, soon confluent, obscured below by the 
white, wooly tomentum; hyphse oblong-cylindrical, simple and contin¬ 
uous, hyaline (or nearly so), 45 x G—7 /'-, nearly entire above, densely 
csespitose in large, crowded, cinereous tufts, covering the upper side of 
the spots; conidia oblong-obclavate, obtuse at each end, mostly one- 
septate, but a few were seen with 4—5 septa, constricted at the septa, 
50—GO x 5—6 /'-. 
Cercospora Heliotropii, E. & E.—On leaves of Heliotropium 
curassaviacum. Albuquerque, New Mexico, S. M. Tracy, No. 384. Am¬ 
phigenous; hyphse loosely fasciculate, short (15—20 /-'•); tufts effused, 
giving the leaf at length a dirty brownish color; conidia oblong-cylin¬ 
drical, 1—3-septate and sometimes constricted at the septa, 20—50 x 4—G 
/'-, subhyaline, with an olivaceous tinge. There are no definite spots, but 
the leaves at first are blotched with yellow in the alfected parts, whisli 
are mostly the upper half of the leaf, though the fungus also attacks the 
stems. 
Cercospora Ceph acanthi, Ell. & Kell.—Fine, well-matured 
specimens of this species were collected at Faulkland, Del., Oct. 3, 1887, 
by Mr. Commons and show that the mature conidia are olivaceous-brown, 
5—7-septate, 35—50 x 4 /'-; the hyphse olive-brown (almost black under the 
hand lens) form erect, compact tufts mostly confined to the upper side of 
the leaf. 
Cercospora Deutzi^e, E & E.—On leaves of Deutzia gracilis. 
Faulkland, Del., September, 1885, Commons, No. 199. Spots amphigen¬ 
ous, small (1—2 millim.), white above, with a thick, raised border, more
