464 PROCEEDINGS OF THE ACADEMY OF [1893. 



Cercospora atrogrisea E. &E. 



On dead stems and pods of Raphanus sativus, Newfield, N. J. 

 Oct., 1893. 



Hyphae cespitose on a small tubercular base, pale brown 1-2-sep- 

 tate, torulose and subuudulate above, 60-70 x 4/jl, forming slaty 

 black, elliptical patches 2-4 mm. long, covered with the minute scat- 

 tered tufts. Conidia slender- obclavate, hyaline, 80-110 x3?-4//, 

 6-12-septate (mostly about 6-septate). The mature conidia are so 

 abundant as to whiten the patches of hyphae. Besides the absence 

 of any spots, and its growth on pods and stems, this differs from C. 

 Nasturtii Pass, in its multiseptate conidia, which are not bacillary as 

 in C. Armoraciae Fckl. , and are narrower and with fewer septa than 

 those of C. Crudferarum E. & E. The hyphae are also shorter 

 than in the last named species. The specc. are overrun with Macros- 

 porium fasciculatum C. & E. 



Macrosporium Nelumbii E. & E. 



On leaves of Nelumbium luteum, Belvue, Kansas. Oct. '93. 

 (Bartholomew, No. 1180). 



Spots dirty brown, suborbicular and subindefinite, 1-6 mm. diam., 

 thickly scattered over the leaf and more or less confluent. Hyphae 

 epiphyllous, scattered and solitary or 2-3 connected at base, brown, 

 3-4-septate, 60-80 x 5—6//, the upper cell mostly swollen. Conidia 

 clavate, 3-5-septate, with a few faint, partial longitudinal septa, pale 

 brown 35-50 x 10-15//, attenuated below into a slender stipe 12-15// 

 long. 



Macrosporium esculentum E. & E. 



On dried up fruit of egg plant (Salanam esculent tan), Newfield, 

 N. J. March, 1893. 



Forms a dense, olive-brown coating, on the dried up fruit. Hyphae 

 subfasciculate, erect, 15-25x4//, rather closely septate, yellowish- 

 brown. Conidia terminal, variable in shape and size, from subglo- 

 bose 8-15//. to oblong-elliptical, 12-22 x 10-15//, or obovate 10-15 x- 

 7-12//., pale yellow-brown, 3-septate becoming more or less distinctly 

 muriform, the globose conidia often sarcinulate- septate, i. e., with 

 septa crossing each other at right angles, running entirely across. 



This differs from M. tomato Cke. in its shorter hyphae and differ- 

 ently shaped, paler conidia.
