Description:Phytopathogenic, associated with small red-brown leaf spots. Mycelium consisting of brown, verruculose to warty, septate, branched, thick-walled, 4 – 5 μm diam hyphae, at time encased in mucoid layer and forming a brown stroma of pseudoparen- chymatal cells; hyphae becoming prominently constricted at septa, cells swelling, becoming muriformly septate, up to 20 μm diam. Conidiophores solitary, erect on hyphae, geniculous- flexuous, 2–8-septate, dark brown, thick-walled, roughened, 15–90 × 3–5 μm. Conidiogenous cells terminal, integrated, medium brown, smooth, consisting of a rachis of sympodial loci, 15 – 30 × 4 – 5 μm; scars round, thickened, darkened, 1–1.5 μm diam. Conidia solitary, aseptate, medium brown, guttulate, verruculose, ellipsoid, apex obtuse, tapering in lower third to truncate hilum, 1–1.5 μm diam, thickened, darkened, (5 –) 6 –7(– 9) × (4–)5(–5.5) μm.

Culture characteristics — Colonies erumpent, spreading, sur- face folded, with moderate aerial mycelium and even, lobate margins, reaching 10 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface olivaceous grey, reverse iron-grey.
