Colony diameter, 7 days (mm): CYA 25°C 35–37; CYA 37°C 50–51; MEA 25°C 25–37; MEA 37°C 26–47; OA 25°C 32–37; YES 25°C 37–50; CREA 25°C 30–37; DG18 25°C 30–45.

Colony characters: CYA 25°C, 7 days: Colonies moderately deep, sulcate; margins irregular; mycelium white; texture velvety; sporulation moderately dense, conidia en masse white; soluble pigments absent; exudates clear droplets; reverse dark brown to light yellow. MEA 25°C, 7 days: Colonies moderately deep, plane to slightly sulcate; margins entire to irregular; mycelium white; texture velvety; sporulation moderately dense, conidia en masse white; soluble pigments absent; exudates clear droplets; reverse light yellow at center, white at edge. YES 25°C, 7 days: Colonies moderately deep, slightly sulcate; margins irregular; mycelium white; texture velvety; sporulation moderately dense, conidia en masse white; soluble pigments absent; exudates clear droplets; reverse light yellow to brown. DG18 25°C, 7 days: Colonies moderately deep, slightly sulcate; margins irregular; mycelium white; texture velvety to floccose; sporulation moderately dense, conidia en masse white; soluble pigments absent; exudates absent; reverse light yellow. OA 25°C, 7 days: Colonies moderately deep, plane to sulcate; margins entire to irregular; mycelium white; texture velvety; sporulation moderately dense, conidia en masse white; soluble pigments absent; exudates clear droplets; reverse yellow. CREA 25°C, 7 days: Acid production absent.

Micromorphology: Conidiophores with smooth stipes, hyaline, 150–400 × 3–6 μm; vesicles hyaline, hemispherical, 8–13 μm wide, fertile over the upper half; metulae hyaline, 4–8 × 2–3.5 μm; phialides hyaline, 5–8 × 1–3 μm. Conidia globose to subglobose, 2–3 μm.
