 Description: Leaf spots angular to irregular, vein-limited, 1-5 mm wide, at first pale reddish brown on the upper surface, pale grayish brown on the lower, later becoming grayish brown in the center with a dark reddish margin on the upper surface whereas on the lower surface dingy grey with indefinite brownish border. Fruiting amphigenous but mostly hypophyllous. Secondary mycelium absent. Stromata rudimentary or up to 30 μm wide, irregular, dark olivaceous brown. Conidiophores 3-20 in a fascicle, divergent, very pale olivaceous to pale olivaceous brown, paler towards the apex, cylindric, substraight to mildly curved or undulate, not branched, indistinctly 0-3 septate, 0-1 geniculate, truncate or rounded at the apex, 5-35 × 2.5-4 μm; conidial scars unthickened. Conidia subhyaline to very pale olivaceous, cylindric to cylindro-obclavate, almost all straight, indistinctly 2-4 septate, obtuse at the apex, sub-truncate at the base, 20-45 × 2.5-3.5 μm, hilum unthickened.

 Note: Pseudocercospora terminaliae (H. Syd.) Deighton (1976) differs from this fungus by its conidiophores and conidia which are relatively wider, thick-walled and dark-coloured. Two species of Cercospora have been recorded in Taiwan, i.e. Cercospora catappae P. Hen-nings (Yamamoto, 1934a) and Cercospora terminaliae (Sawada, 1942b), and they are pos-sibly synonymous.
