Description:Leaf spots mostly epiphyllous, rarely amphigenous, irregular, dark brown, 1–2 mm diam, turning pale grey in centre with age. Conidiomata pycnidial, solitary, immersed, breaking through the epidermis by irregular rupture, 100–200 m diam; wall of 3–6 layers of medium brown textura angularis, exuding a slimy conidial cirrhus. In culture sporulating via large dark brown to black sporodochia, producing a dark brown conidial mass. On OA: Stroma consisting of brown, verruculose cells that give rise to aggregated conidiophores. Conidiophores medium brown, verruculose, subcylindrical, 0–1-septate, 15–20  4–7 m. Conidiogenous cells terminal, verruculose, medium brown, subcylindrical, proliferating sympodially and percurrently, 7–15  4–7 m. Conidia solitary, medium brown, verruculose, subcylindrical, apex obtuse, base truncate, 4–5 m diam with marginal frill; hilum unthickened not darkened, 5–8-septate, (30–)40–52(–55)  (5–)6(–7) m. Culture characteristics — Colonies flat, spreading, surface folded, with moderate aerial mycelium and feathery, lobate margins, reaching 8 mm diam after 2 wk at 25 C. On MEA surface olivaceous grey, reverse iron-grey. On PDA surface pale olivaceous grey, reverse olivaceous grey. On OA surface olivaceous grey.
