 Description: Leaf spots suborbicular to irregular, 1-5 mm wide, grayish brown with a dark margin, paler on the lower surface. Fruiting amphigenous. Stromata well developed, erumpent, subglobose to elongated, 30-100 μm wide, olivaceous brown to dark brown. Conidiophores dense to very numerous in a fascicle, in mass darkly coloured, singly pale olivaceous to pale olivaceous brown, uniform in colour, indistinctly 0-2 septate, slightly constricted at the septa, branching absent, 0-1 geniculate, straight to curved, bluntly rounded at the apex, 10-25 × 1-3 μm; conidial scars unthickened. Conidia subhyaline to very pale olivaceous, acicular or narrowly obclavate, some cylindric or longer one may be linear, straight to slightly curved, 1-6 indistinctly septate, conic or blunt at the tip, truncate or obconically truncate at the base with an unthickened hilum, 20-55 × 1.5-3 μm.

 Note: The amphigenous fruiting, well developed stromata and very densely fasciculate conidiophores of this fungus separate this species from others on Cassia spp. However, Cercospora sphaeroidea Spegazzini (Anal. Soc. Scient. Argentine 16:169, 1883) is much similar to this fungus but differs only by its relatively wider (4-5.5 μm) conidia.
