Saprobic on submerged decaying wood. Asexual morph: Colonies on wood effuse, hairy, dark brown, scattered or in small groups, glistening. Mycelium partly immersed, partly superficial, composed of septate, smooth, pale brown to hyaline hyphae. Conidiophores macronematous, mononematous, erect, solitary or caespitose, straight or slightly flexuous, cylindrical, slightly narrower at the apex, smooth-walled, septate, unbranched, dark brown, 50–130 × 3.4–5 µm ( = 95 × 4.2 µm, n = 15). Conidiogenous cells monoblastic, integrated, terminal, determinate, cylindrical or lageniform, brown, 11.5–22 × 4.5–6 µm, truncate and with a darkened scar at the apex, sometimes elongating percurrently. Conidia acrogenous, ovoid to obpyriform, with a conical apical cell, mostly 3-septate, rarely 4-septate, smooth-walled, brown, with apical cell pale brown to subhyaline, 19–25 × 8.5–11.5 µm ( = 22 × 10 µm, n = 20), rostrate, guttulate, truncate at the base, thickened and darkened at the septa, rarely with a mucilaginous sheath at the apex. Sexual morph: Undetermined.
