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 View FIGURE 1 , 2b, h View FIGURE 2 , 5k View FIGURE 5 ), irregular, margin undulate, flat, mycelia concentric, granular ( Figure 1 g, p View FIGURE 1 , 2a, g View FIGURE 2 , 5j View FIGURE 5 .). 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 View FIGURE 1 and 2c, i View FIGURE 2 ), Conidia brown, thick-walled, spherical or sub-spherical, 2.5–10 μm (x̄=6.5) diam., produced in large number ( Figure 5l View FIGURE 5 .)

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