cannot be well defined. The conidia are stouter than 

 described by Cooke (Grev. XII, p. 30) and Ellis (Jour. My- 

 col. I, p. 34) and many times more septate, but the septa- 

 tion of long conidia is very variable. It is probably only 

 a variation of Cooke's species. 



8. Cercospora Diode.e Cke. Spots amphigenous, light 

 brown with narrow raised border bounded by dark brown 

 above, suborbicular or semicircular on edge of leaf. Hy- 

 phse epiphyllous, rarely hypophyllous also, in dense tufts 

 from a tuberculate stroma, short, 10 — 30 X 4 — 5, reddish 

 brown, longer ones septate and toothed. Conidia slender, 

 terete, fuscidulous, 3 — 5 — septate, 30 — 100 X 2, 5 — 3.

9. Cercospora Tephrosl^ n. sp. Spots amphigenous, 

 small, angular or suborbicular, i — 2 ;«///., elevated, black- 

 ish brown. Hyphse epiphyllous, fasciculate, fascicles 

 crowded, reddish, flexuous or dentate, 50 — 100 X 4, 5 — 5. 

 Conidia obclavate, subhyaline and tinge of same color as 

 hyphae, 5 — 8 — septate, usually straight, 70 — 130 X 4 —

10 Cercospora truncatella n. sp. Spots amphigenous, 

 suborbicular, whitish with narrow light brown border, 

 2 — 4 mm. Hyphse amphigenous, fasciculate, reddish 

 brown, septate, geniculate or nearly straight, conidial scars 

 distributed along at geniculations, 70 — 250 X 4, 5. Coni- 

 dia hyaline, faintly septate, tapering very gradually from 

 truncated base to obtuse apex, rarely rounded at base, 50 — 

 150 X 3, 5 — 4. Very different from C. fiisco-virens.
