| Description： |
Leaf spots none or merely indefinite yellowish discoloration on the upper surface. Fruiting chiefly hypophyllous, distinct as effuse sooty olivaceous layer forming roundish spots, 1-5 mm in diameter; sometimes epiphyllous fruiting is visible as minute black pustules scattering over the spot. Stromata a few brown cells or up to 25 μm wide. External hyphae sometimes present, arising from the fascicle bearing secondary conidiophores as side branches, 2-3.5 μm wide, pale olivaceous brown. Conidiophores chiefly fasciculate, emerging through the stomata, dense, pale olivaceous brown, substraight to curved or flexuous, geniculate, branched, sometimes nodulose, 1-5 septate, with constrictions at the septa, rounded or subtruncate at the apex, 15-110 × 3-5 μm; conidial scars inconspicuous. Conidia olivaceous to pale olivaceous brown, cylindric, obclavate or cylindro-obclavate, straight to slightly curved, 2-14 indistinctly septate, sometimes constricted at the septa, acute or obtuse at the apex, obconically truncate at the base with an unthickened hilum, 20-100 × 3-5 μm. | |||
