5. Cercospora person ATA (B. & C. ) Ell. Spots am- 

 phigenous, circular, dark brown, ususally darker below, 

 frequently arched below, 2 — 4 mm. Hyphse mostly hypo- 

 phyllous, frequently also epiphyllous, densely fasciculate, 

 reddish brown, usually short and continuous, toothed, or 

 50 — 70 long, septate and subgeniculate 5 — 7 in diameter. 

 Conidia obclavate, 30 — 50 X 5 — 7, or up to 70 long, pale 

 olive brown, 3 — 10 — septate. Agrees in all respects with 

 X. A. F. 2480. 



On leaves oi AracJiis Jiypogea^ 2157, Auburn, September 

 7, 1 89 1, Atkinson, also collected at Columbia, S. C. , 

 November 17, 1888. 



6. Cercospora Occident alis Cooke. Spots much as in 

 C. persoiiata^ hyphae amphigenous, paler than in specimens 

 o{ personata. Conidia vary more, being up to 170 long, 

 paler also in color and frequently cylindrical. The oblong 

 spores are not all uniseptate as stated by Berkely (Grev. 

 Ill, p. 106) but frequently 3 — 5 or more septate and the 

 long obclavate ones are multiseptate. Thiimen's specimens 

 (1964, C. personata var. CassicF Thiim. ]\Iyc. Univ.) also 

 agree with mine, the oblong spores not being one septate, 

 but usually several times septate. I consider it quite 

 distinct from C. personata. 



On leaves of Cassia occidentalism ^547^ Auburn, Julv, 

 1890, Atkinson; 2128, Duggar. In the latter the clusters 

 of hyphge are in small patches or widely diffused, no dis- 

 tinct spots. In this respect all the specimens I have seen 

 differ more or less from those of C. personata on Arachis 

 hypogea. 



7. Cercospora moricola Cke. Spots brown, large, 

 irregular. Hyphae hypophyllous, fasciculate, few in a 

 cluster, reddish brown, septate, denticulate toward apex, 

 40 — 70 X 4, 5 — 5. Conidia hyaline, long, slender, terete, 

 10 — 20 — septate, straight or curv^ed, 70 — 200 X 4.
