| Description： |
Leaf spots dark brown, visible on both surfaces, 0.5-5 mm wide, angular to irregular, confluent. Fruiting amphigenous, but usually more abundant on the upper surface. Stromata small or up to 25 μm wide, substomatal, pale olivaceous. Conidiophores densely fasciculate, emerging through the stomata, and also produced as lateral branches from the secondary mycelial hyphae, pale olivaceous, smooth, clavate, variously curved or crooked, 0-2 septate, constricted at the septa, rarely branched, conically rounded at the apex, 7-40 × 3-4.5 μm; conidial scars unthickened and inconspicuous. Secondary mycelium external, arising from among the fascicle of conidiopores or occasionally as proliferations of the conidiophores, sometimes epiphyllous but sometimes only hypophyllous sometimes plentiful: hyphae pale olivaceous, repent, smooth, septate, branched, 1.5-2,5 μm wide, bearing secondary conidiophores (similar) to the primary ones) as short lateral branches. Conidia subhyaline to very pale olivaceous, narrowly obclavate or linear, shorter ones may be cylindric, straight, slightly curved or undulate, 3-11 septate, subacute to subobtuse at the apex, long obconic or obconically truncate at the base, 25-80 × 2-3 μm; hilum unthickened and inconspicuous. |
