Ciri dan struktur
Saprobic on submerged decaying wood. Sexual morph: Undetermined. Asexual morph: Colonies on the substratum superficial, effuse, hairy or velvety, black. Mycelium mostly immersed, composed of branched, septate, smooth, pale brown hyphae. Conidiophores (17.5–)20–44.5 (–65.5) × 2.5–4.0 μm (x ‒ = 32.2 × 3.4 μm, n = 20), macronematous, mononematous, erect, straight or slightly flexuous, thick-walled, smooth, orange-brown or brown, 3–7-septate. Conidiogenous cells monoblastic, integrated, terminal. Conidia 16.5–24 × 11–15 μm (x ‒ = 20.3 × 13 μm, n = 30), solitary, dry, acrogenous, broadly oval to subglobose, muriform, transversely and longitudinally septate, with transverse septa typically spanning the whole conidial width, with longitudinal septa typically incomplete, short; dark-blackish brown to black, smooth, narrowly truncate at the base. Conidia germinating on PDA within 24 h. Germ tubes produced from the basal cell. Colonies on PDA reaching 3 cm diameter in 30 days at 20–25 °C, pale brown, with dense, tight mycelia on the surface, sparse at the margin, reverse dark brown, with smooth margin. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, monoblastic, integrated, hyaline to pale brown, smooth. Conidia broad oval to subglobose, muriform, strongly constricted at all the septa, hyaline when young, brown to grayish-brown when aged, smooth-walled.
