Description:

Foliar epiphytes appearing as “sooty moulds” involving black mycelium masses on surface of leaves. Sexual morph: Unknown. Asexual morph: Mycelium comprising dense, brown to dark brown, friable, branched, septate hyphae, which are deeply constricted at the septa, thick-walled, moniliform, and anastomosing, having cells of 17–20 × 12–16 μm. Conidiophores 15−20 × 10−15 µm (x̄ = 16.2 × 10.2 µm, n = 10), arising from hyphae, erect, simple or branched, pubescent, brown, septate, cylindrical. Phialides develop on moniliform hyphae, which are more or less subsphaerical, ellipsoidal to cylindrical, tapered or slightly flared, pale brown to brown, phialides occurring in groups on hyphae or globose, pale brown to brown, with collarette. Phialoconidia 16−20 × 7−8 µm (x̄ = 19 × 7.5 µm, n = 10), brown, 1-3 septate, smooth-walled.

Material examined: Puerto Rico, Maricao, on Vitex sp. (Lamiaceae), 18 November 1913 (ILL00081779).
