Paraphyses hyaline, septate, dissolving at maturity. Asci 8-spored, unitunicate, clavate, 80–140 × 10–14 µm, with a refractive ring. Ascospores parallel in ascus, long fusiform to filiform, straight or slightly curved, 5–8(–12)-septate, not constricted at septum, hyaline, smooth, 36–75 × 3–5 µm. Asexual state phialophora-like. Conidiophores branched, hyaline to brown. Conidiogenous cells phialidic, terminal to intercalary, cylindrical to lageniform, straight or curved, hyaline, with a cylindrical, refractive collarette. Conidia straight to curved, 5–12.5 × 3–5 μm. Hyphopodia slightly lobed, brown, up to 20 μm diam.
On PDA or MEA, hyphae branched, septate, hyaline to brown, smooth, 1–5 μm diam. Colonies on PDA 6.2 cm diam after 7 days at 25 °C; surface olivaceous black; marginal hyphae straight or curling back strongly towards center of colony, hyaline (Description from Wong, 2002).
