　Description： Leaf spots circular or irregularly suborbicular, 1-8 mm (mostly 2-4 mm) in diameter, grey brown at center with a dark reddish brown margin, dead tissues may drop out leaving the leaf with holes. Fruiting amphigenous. Secondary mycelium absent. Stromata absent or a few brown cells. Conidiophores arise singly or 2-4 (rarely up to 10) in a fascicle, deep olivaceous brown to pale brown, paler towards the apex, irregular in width, curved or crooked, not geniculate, not branched, multiseptate, sometimes slightly constricted at the septa, subtruncate at the apex, 60-180 × 4-7 μm, conidial scars thickened conspicuously. Conidia acicular, hyaline, curved or undulate, indistinctly multiseptate, subacute at the apex, truncate at the base with a thickened hillim, 100-300 × 3-4 μm.

　Note： Cercospora houttuymae Togashi & Katsuki (Bot. Magazine Tokyo 65: 21, 1952) differs from this fungus by the presence of stromata and by its densely fasciculate conidiophores which are uniform in colour and width with dimension 10-55 μm × 3-4.5 μm; and by its conidia which are obclavate and pale olivaceous brown in colour.
