Description

Saprobic on dead petiole of Livistona chinensis. Sexual morph Undetermined. Asexual morph: Hyphomycetous. Colonies sporodochial, punctiform, gregarious, raised, dark brown to black. Mycelium mostly immersed, smooth, consisting of septate, thin-walled, hyaline to pale brown hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 5–10 × 3–5 μm (x̅ = 6.8 × 4 μm, n = 30) holoblastic, monoblastic, integrated, determinate, terminal, obconical, pale brown, smooth. Conidia 15–20 × 18–23 μm (x̅ = 18 × 20 μm, n = 30), acrogenous, solitary, dry, thin-walled, smooth-walled, irregular-shaped, mostly subglobose, 2–3-transversely septate, 1–2-longitudinal septate, clathrate, muriform, dictyoseptate, slightly constricted at septa, brown to dark brown, with 1–2 small, subround, depressions on the surface of each cell.
