Description:Colonies on OA reaching 52 – 55 mm after 14 d at 25 °C, olive brown (4E3/F8), flat, velvety to granular, with regular margin; reverse olive brown (4E3/F8) to black. On PDA attaining 50–56 mm diam after 14 d at 25 °C, olive brown (4F4/F8), with a raised or umbonate centre and radially folded towards the periphery, velvety to dusty or granular, with regular margin; reverse dark green (30F8) to black. On SNA reaching 37– 40 mm after 14 d at 25 °C, olive brown (4D4/F6), flat, velvety, with lobulated margin; reverse olive brown (4D4/F6) to black. Mycelium superficial and immersed, composed of septate, branched, 1.5 – 3 μm wide, pale olivaceous brown, with smooth and thin-walled hyphae. Conidiophores erect, cylindrical, non-nodulose, septate, septa darkened, branched, frequently branching near the base in a 90° angle, up to 150 μm long, 3–4 μm wide, pale brown, smooth and thin-walled. Conidiogenous cells terminal or intercalary, cylindrical, 8 – 46 × 2 – 3.5 μm, bearing up to four conidiogenous loci of 1–1.5 μm diam, darkened and refringent. Ramoconidia aseptate, subcylindrical, straight, 24.5–46 × 2–3.5 μm, pale brown, finely roughened, with scars protuberant, thickened and darkened. Conidia forming long branched chains with up to 14 conidia in the terminal unbranched part, pale olivaceous brown, smooth and thin-walled, with protuberant conidial hila, not darkened; small terminal conidia aseptate, obovate to nearly cylindrical, 3.5–4.5 × 2–2.5 μm (av. (± SD) 4.1 (± 0.3) × 2.3 (± 0.3)); intercalary conidia aseptate, ellipsoidal, 4 – 6 × 2 – 3 μm (av. (± SD) 5.3 (± 0.6) × 2.4 (± 0.4)); secondary ramoconidia 0 –1-septate, usually constricted at septum, subcylindrical, 8 –17 × 2.5–3 μm (av. (± SD) 12.2 (± 2.6) × 2.8 (± 0.3)).
Cardinal temperature for growth — Optimum 25 °C, maxi- mum 35 °C, minimum 15 °C.
