Leaf spots none or merely indistinct tan suborbicular to subangular areas on the upper surface, 2-10 mm wide. Fruiting hypophyllous, scantily effuse, olivaceous. Secondary mycelium external, well developed: hyphae subhyaline to very pale olivaceous brown, 1-4 um wide, emerging through the stomata, repent or arcuate and climbing up the leaf hairs, indistinctly septate, branched, bearing secondary conidiophores terminally and laterally. Stromata lacking or sometimes up to 25 μm wide, brown. Primary conidiophores up to 15 in a fascicle, pale olivaceous to pale olivaceous brown, slightly wavy, more or less cylindrical, 0-2 septate, not branched, not geniculate, rounded or truncate at the apex, 10-30 × 3-4 μm; conidial scars unthickened and inconspicuous. Secondary conidiophores borne terminally and laterally on the external mycelial hyphae, pale to very pale olivaceous brown, straight to curved, sometimes strongly tortuous, 0-2 septate, sometimes slightly constricted at the septa, simple or with a short branch, occasionally once abruptly geniculate, rounded or conically truncate at the apex, 6-50 × 3-4 μm. Conidia pale olivaceous, narrowly cylindro-obclavate or subacicular, shorter ones may be cylindrical, straight to slightly curved, 3-12 septate, not constricted, subobtuse at the apex, obconically truncate at the base, 35-115 × 3-3.5 μm. | |||
