Fusoidiella depressa  

Leaf spots at first small yellowish angular areas without a definite margin, later becoming brown, angular and vein-limited.
Anamorph: clusters of conidiophores hypophyllous, usually deep brown but occasionally paler, punctiform, evenly and on old spots densely distributed over the spot. Stroma substomatal, composed of a fairly dense aggregation of pale olivaceous hyphae. Conidiophores numerous, in a dense somewhat divergent fascicle arising from the stroma, slightly or often strongly incurved; 20-70 (-100) µm long, 4-8 µm diam., olivaceous, not geniculate, often somewhat rough-walled towards the apex. Conidial scars fairly conspicuous, moderately thickened, 1.5-2.5 µm diam., the old ones lying flat against the side of the conidiophore or on slight and not very conspicuous shoulders. Conidia 20-78 x 6·5-11 µm, concolorous with the conidiophore tips (somewhat paler than most of the conidiophore), mostly obclavate-fusiform but some shorter ones broadly fusiform or ovoid, straight or slightly curved, minutely roughened, thin-walled, obtuse or sometimes broadly rounded at the apex, shortly and roundly tapered at the base to a truncate, conspicuous and moderately thickened scar, mostly 1-septate, sometimes aseptate or 2- or 3-septate.
Teleomorph: not known.
