ter I reported in the April (1891) number of the Agricul- 

 tural Journal, Montgomery, Ala. Two species, one cred- 

 ited to Cooke & Ellis and the other to Ellis & Everhart, 

 are, I believe, also described for the first time. One other 

 species is added by reducing Hebninthosporium Petersii 

 B. & C. to synonymy. 



One other species, heretofore described as Cercospora 

 persica Sacc. and later as Cercosporella persica Sacc. (Fung. 

 Ital., tab. 67; Sylloge Fung., Vol. IV, p. 218), is excluded. 

 During September, 1890, I collected it at Gold Hill and 

 recognized it as a Fusarium. It should read F. persicuin 

 (Sacc). 



The measurements of conidiophores and conidia are 

 given in terms of the micromillimetre. 



There are a few references to numbers of specimens col- 

 lected by Langlois in Louisiana. These specimens were 

 deposited in the herbarium of the Ala. Polyt. Inst, by C. 

 L. Newman, who received them as exchanges. 



Mr. J. B. Ellis has kindly favored me with several 

 specimens for comparison and has examined notes and 

 specimens of a few species. Like favors from others are 

 mentioned in connection with the species. 



I. Cercospora cerasella Sacc. Spots amphigenous, rustv 

 brown, brighter above with dark border, 2 — 4 mm. 

 Hyphse amphigenous, fasciculate, fascicles clustered in 

 center of spot or in two or three clusters in different places, 

 olive reddish brown, continuous, subgeniculate or dentate 

 toward apex, 30 — 50 X 3.5 — 4. Conidia same color but of 

 a lighter shade, obclavate to acuminate, 5 — 10 — septate, 

 guttulate, 40—75 X 3-5— 4- 5- 



I have compared my specimens with No. 16 fascicle i of 

 Brioso et Cavara's Funghi Parassiti delle Piante Coltivate 

 od Utile, and they agree in all essential respects except 

 that the spots in the latter are not well defined, but this 

 may be due to the fact that the leaf in the fascicle I have
