2.5. Diagnostic Notes

Symptoms: Leaf spots circular, coalescing, dark brown to blackish-brown, 5-10 mm diameter, occasionally a yellow halo appearing in mature spots (Mulder & Holliday 1974).

Pathogen: Fruiting amphigenous, stroma globular, brown to black. Conidiophores in dense to very dense fascicles, pale fuliginous or olivaceous brown, uniform in colour and fairly so in width, straight to slightly curved, very sparingly septate, longest ones 1-3 mildly to abruptly geniculate, not branched although some abrupt geniculations appear almost like incipient branches, medium spore scar at bluntly rounded tip, 3—5 x 10—70 µm; conidia medium dark olivaceous, cylindric to slightly spindle shaped, straight to mildly curved, 1—8 septate, mostly 2—5, ends bluntly rounded or base sometimes long obconically truncate, 5—7.5 x 20—70 µm (Chupp 1954). For additional information see Deighton (1967), Ellis (1976), Hsieh & Goh (1990), Mulder & Holliday (1974), Sivanesan (1984) and Shin & Kim (2001).
