 Description: Colonies diameter on Oat Meal Agar larger than 60 mm in 38 days at 25°C, effuse, plane, with more or less floccose at the center, brownish grey to greyish brown; reverse greyish brown to brown or dark brown. Mycelium mostly immersed, composed of branched, septate, smooth, subhyaline to pale brown or middle brown, 1.4-7.0 μm hyphae. Conidiophores macronematous, mononematous, single or cluster, simple or branched, straight or slightly curved, septate, smooth, brown, paler towards the apex, 39.0-210.0 X 5.4-9.0 μm, often elongated- proliferation.
