　Description： Leaf spots angular to suborbicular, vein-limited, 1-4 mm wide, often confluent, yellowish brown with a narrow darker brown margin. Fruiting chiefly hypophyllous, grayish, velutinous. Secondary mycelium external, copious: hyphae pale olivaceous brown, septate, branched, arcuate, intertwining and climbing up the stellate leaf hairs, bearing secondary conidiophores as erect lateral branches. Stromata a few brown cells or up to 30 μm wide, substomatal. Primary conidiophores densely fasciculate, emerging through the stomata, moderately olivaceous to pale brown, paler towards the apex, curved or tortuous, simple or branched, 1-3 septate, 0-2 geniculate, rounded or truncate at the apex, 35-60 × 4-5.5 μm; conidial scars visible but not conspicuously thickened. Secondary conidiophores borne terminally and laterally on the external secondary mycelial hyphae, pale olivaceous brown, 0-1 septate, straight or sinuous, not branched, rounded or truncate at the apex, 10-25 × 4-5 μm; conidial scars invisible. Conidia yellowish to pale olivaceous brown, cylindric to linear, straight to curved, 1-11 septate, obtuse at the apex, short obconically rounded or truncate at the base, 20-115 × 4.5-6 μm; hilum unthickened.

　Note： Mycovellosiella solani-torvi (Frag. & Cif.) Deighton (Mycol. Pap. 137:14-17, 1974) differs from this fungus by its conspicuously thickened conidial scars. Pseudocercospora trichophila (F. L. Stevens) Deighton (1976) differs from this fungus by its relatively paler external mycelial hyphae and paler conidiophores and by its paler conidia which are clavato-cylindric in shape with the basal cells more abruptly tapered towards the small unthickened hilum.
