Colonies on PDA covered the entire 9 cm plate in 10 days at 28–30 0 C, grey-black floccose, reverse black, irregular, margin undulate, exudates present, appearance velvety, dull, umbonate ( Figure 3d, e ). Conidiophore 600–800 μm (x̄=752) in length and 4–6 μm (x̄=5.2) in width, subhyaline, pseudo septate, branched, basal cell swollen and darker. Conidia 14–15.5 μm (x̄=14.7) ellipsoid, obclavate or slightly curved, hyaline arranged on rachis, distinct conidiogenous nodes ( Figure 3f .).

Notes: The isolate ( MZ277275 ) from Oryza sativa showed 100% similarity to KU715234 (identity: 566/566, gaps: 0/566).
