　Description： Colonies diameter on Oat Meal Agar 40 mm in 57 days at 25°C, effuse, velvety to hairy, present fasiculate, olive brown to yellowish brown; reverse olive brown to dark brown. Mycelium mostly superficial, composed of branched or anastomosis, septate, smooth or verrucose, subhyaline to pale yellowish brown hyphae. Conidiophores macronematous, mononematous, straight or flexuous, septate, often in dense fascicles or directly raising from the creeping hyphae, simple or branched, subhyaline to pale yellowish brown or reddish brown, 24.0-208.0 X 5.0-8.4 μm. sometimes swollen at the base. Conidiogenous cells sympodial, with short denticle scattered. Conidia acropleurogenous, helicospore, hyaline to subhyaline or pale yellowish brown, smooth, rounded at the end conico-truncate at the base, coiled into 1 1/4 spirals, (4)5-8-septate, 19.2-24.2 μm in diameter, 7.9-9.2 μm wide.
