Hyphomycetous. Sexual morph: Unknown. Asexual morph: Aerial hyphae coarsely verrucose, olivaceous-green, thick-walled, 4–5.0 µm wide, with thin septa. Conidiophores not discerned from vegetative hyphae, reduced to conidiogenous cells. Conidiogenous cells 10−11.5 × 2.0−3.1 µm (x̄ = 10.2 × 2.2 µm, n = 5), integrated, mainly terminal, at times lateral, erect, arising from aerial hyphae, straight to somewhat flexuous, subcylindrical to cylindrical, pale brown, proliferating sympodially forming crowded, clearly pigmented scars that are thickened and refractive. Conidia 8.5−13 × 3.5−4.7 µm (x̄ = 11.3 × 4.1 µm, n = 10), ellipsoidal, subcylindrical to cylindrical, fusiform or sometimes irregular shaped, verrucose, obovate to obconical, pale brown, with truncate base, with a conspicuous, slightly pigmented, refractive hilum.
