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

Micromorphology: Conidiophores with smooth stipes, hyaline, 300–700 × 4–8 μm; vesicles hyaline, subglobose, 12–26 μm wide, fertile over the upper half; metulae hyaline, 5–7 × 1.5–3 μm; phialides hyaline, 6–8.5 × 1.5–3 μm. Conidia globose to subglobose, 1.5–2.5 μm.
