Colonies on PDA are fast-growing, reached approximately ¾ th of the 9 cm plate in two weeks at 28–30 0 C, black, reverse black initially, turned greyish, or brownish black with aging (Figure 1h, q, 2b, h, 5k), irregular, margin undulate, flat, mycelia concentric, granular (Figure 1 g, p, 2a, g, 5j.). Conidiophores 1.5–3.0 mm (x̄=2.7) in length and 10–14 μm (x̄=12) in width, aseptate, thick-walled, smooth and hyaline with round vesicle. Phialides columnar with radial chains covering the entire surface of the vesicle; Conidial heads large 750–850 μm (x̄=824), black, globose (Figures 1i, r and 2c, i), Conidia brown, thick-walled, spherical or sub-spherical, 2.5–10 μm (x̄=6.5) diam., produced in large number (Figure 5l.)

Notes: The Aspergillus niger recovered from Arachis hypogea kernel (MZ314419 and MZ331798) showed similarity to KT898605 (identity: 378/388, gaps: 0/388) and MH091025 (identity: 587/588, gaps: 1/588) respectively. Those isolates from the seed coat (MZ277273 and MZ314420) were 99% similar to HQ285532 (identity: 600/602, gaps: 1/602) and EU440778 (identity: 551/553, gaps: 2/553) respectively. The isolate from Vigna sinensis (MZ323689) showed 98.48% similarity to MT316340 (identity: 584/593, gaps: 3/593).
