 Description: Leaf spots angular to irregular, vein limited, without distinct margin, 0.5-4 mm wide, brown on upper surface, grey-brown on lower surface, leaf tissue around the spots discolorated. Fruiting amphigenous. Secondary mycelium external: hyphae pale olivaceous to pale oliva-ceous brown, bearing secondary conidiophores laterally, 2.5-3.5 μm wide. Stromata a few brown cells or up to 40 um wide, substomatal or erumpent. Conidiophores either up to 20 in a fascicle or arise singly as side branches from the external hyphae, pale olivaceous to pale olivaceous brown or in mass appearing darker, uniform in colour and width, sometimes branched, straight below and slightly sinuous towards the apex, tip subtruncate or rarely with slight geniculation, 1-3 septate, 25-90 × 3-4 μm; conidial scars inconspicuous. Conidia subcylindric or cylindro-obclavate, straight to mildly curved, concolorous with the conidio-phores, 2-10 septate, tip obtuse, base shortly tapered to a truncate unthickened hilum, 40-90 × 4-5 μm.
