Colonies on PDA are moderately fast-growing, reached approximately ¾ th of the 9 cm plate in two weeks at 28–30 0 C, black, reverse black but turned greyish with aging, irregular, margin undulate, appearance flat, granular ( Figure 5d, e ). Conidiophore 1.5–2.5 mm (x̄=2.4) in length and 10–12 μm (x̄=11.2) in width, aseptate, rough-walled, hyaline with rounded vesicle. Conidial head large 750–850 μm (x̄=810), black, globose, with radial phialides. Conidia brown, thick-walled, spherical ( Figure 5f .)
