Cultural characteristics: Colonies on MEA at 25 ºC attaining about 50−90 mm diam after 14 days, appearing smooth and slimy due to abundant sporulation, pinkish white. Within first 5 weeks’ colonies filamentous developing into white, setae-like mycelia becoming brown initially and then black at the irregular margin. Vegetative hyphae hyaline, transversely septate, smooth, sometimes becoming brown to dark brown when mature, smooth, thin-walled, 2−9 μm wide, transversely septate. Conidiogenous cells undifferentiated, intercalary or terminal on hyaline hyphae or arising as short lateral branches. Conidia 5.5−18 × 3−6 µm ( x = 10.2 × 4.8 µm, n = 20), produced synchronously in dense groups from small denticles, and also formed percurrently on short lateral denticles, hyaline sometimes becoming brown, ellipsoidal, aseptate, smooth. Endoconidia are produced by an intercalary cell. Sexual morph: Unknown.
