Aspergillus flavus Link , Mag. Gesell. naturf. Freunde, Berlin 3 (1–2): 16 (1809)

Index Fungorum registration number: 209842

Colonies on PDA are fast-growing, reached approximately ¾ th of the 9 cm plate in ten days at 28–30 0 C, black, reverse black, irregular, margin curled, appearance granular, flat, mycelia less concentrated concentric turning filamentous on maturation ( Figure 5g, h ). Sclerotia dark brown to black. Conidiophore 400–830 μm (x̄=520) in length and 8–12 μm (x̄=10) in width, smooth-walled, stout with dichotomous or trichotomous branching, rhizoids at the base, globose vesicles of 20–50 μm (x̄=36) diam. ( Figure 5i ).

Notes: The Aspergillus flavus isolate ( MZ314421 ) was 99.63% similar to MH329787 (identity: 536/538, gaps: 2/538).
