 Description: Leaf spots suborbicular to irregular, 1-4 mm wide, pale brown to ferruginous, without distinct margin. Fruiting amphigenous, densely effuse or punctiform, dark olivaceous. Stromata amphigenous, well developed, dark olivaceous brown, 20-55 μm wide. Secondary mycelium external: hyphae pale olivaceous, septate, 1.5-2.5 μm wide, bearing secondary conidiophores as side branches. Primary conidiophores densely fasciculate on the stromata, pale olivaceous brown, straight to curved, 0-3 septate, rarely branched, 0-2 mildly geniculate, conically truncate or rounded at the apex, 10-35 × 3-4.5 μm; conidial scars unthickened. Secondary conidiophores borne singly on the external secondary mycelial hyphae, similar in respect to the primary conidiophores, 7-45 × 3-4.5 μm. Conidia subhyaline to pale olivaceous brown, cylindric to obclavato-cylindric, mostly straight, 1-7 septate, not constricted at the septa, subobtuse to rounded at the apex, obconic to obconically truncate at the base, 8-65 × 2.5-4 μm; hilum unthickened.

 Note: This fungus differs from Cercospora latens EII.& Ev. (Jour. Mycol. 4:3, 1888) (Syn. C. lespedezae Ellis & Dearness) by its amphigenous fruiting, big stromata, cylindric conidia, and by the presence of external secondary mycelium.
