| Description： |
Leaf spots amphigenous, indefinite pale brown discoloration on upper surface, distinct on lower surface as grayish brown, somewhat floccose angular patches, 2-7 mm wide. Fruiting amphigenous, more abundant on lower surface. Stromata only epiphyllous, dark brown, irregular, up to 65 μm wide. Secondary mycelium only hypophyllous, external hyphae pale olivaceous to pale brown, 2.5-4 μm wide, septate, branched, bearing secondary conidio-phores terminally and laterally, entangled between leaf hairs. Conidiophores sometimes fasciculate on epiphyllous stromata, but chiefly borne terminally and laterally on hypophyllous external hyphae, pale olivaceous brown, cylindric to sinuous or irregular in width, continuous when short, septate when longer, simple or occasionally branched, up to 70 μm long, 4-5 μm wide; conidial scars thickened slightly, scarcely visible on a shoulder or lying flat against the side of the conidiophore. Conidia cylindric, subhyaline to very pale olivaceous brown, mostly straight, some curved, 1-7 septate, sometimes constricted at the septa, catenulate, apex broadly obtuse, base rounded or shortly tapered to a slightly thickened hilum, 20-100 × 4-5 μm. |
