Description. Saprobic on submerged decaying wood in freshwater habitats. Sexual morph: Undetermined. Asexual morph: Colonies effuse, brown to dark brown, hairy, glistening. Mycelium partly superficial, partly immersed in the substratum, composed of hyaline to pale brown, septate, branched hyphae. Conidiophores 37–55 × 3–4 μm ( = 46 × 3 μm, n = 15) macronematous, mononematous, solitary or in a small group of 2–4, cylindrical, straight or slightly flexuous, 3–8-septate, dark brown, paler at the apical part, rounded at the apex. Conidiogenous cells 6–8 × 3–4 μm ( = 7 × 3 μm, n = 15), integrated, terminal, monoblastic, cylindrical, brown. Conidia 400–568 × 13–16 μm ( = 484 × 15 μm, n = 20), 6–7 μm at the narrowest apical region, acrogenous, solitary, elongate, obclavate, rostrate, distoseptate, tapering towards the apex, truncate at the base, rounded at apex, dark olivaceous to dark brown, straight or slightly curved, guttulate, thick-walled, smooth, conidia percurrent proliferation which forms another conidium at the apex.
