　Description： Leaf spots distinct on the lower surface, angular, vein limited, grayish brown to dark, appearing as slightly raised irregular dark spots on the corresponding upper surface, 0.5-2 mm wide or confluent to form larger spots. Fruiting strictly hypophyllous. Stromata well developed, subimmersed, olivaceous brown, mostly elongated, up to 45 μm wide. Secondary mycelium external: hyphae from the base of the fasciculate conidiophores, septate, branched, repent, bearing secondary conidiophores as side branches, pale olivaceous to very pale olivaceous brown, 1.5-4 μm wide. Conidiophores chiefly fasciculate, dense, pale olivaceous to very pale olivaceous brown, sometimes almost colourless at the apex, straight or 1-2 abruptly geniculate, not branched, 0-2 septate, attenuated, rounded or subtruncate at the apex, 10-30 × 2.5-5 μm; conidial scars unthickened. Conidia obclavate or cylindro-obclavate, concolorous with the conidiophores, mostly straight, 2-8 plainly septate, subobtuse or narrowly rounded at the apex, obconically truncate at the base, 25-65 × 3-4 μm.
