Type: Foliicolous Fungi; Description: Mycelium both internal and external. Hyphae of internal mycelium smooth, hyaline, 1–4 μm wide, connected with the external mycelium by hyaline hyphae passing through stomata; hyphae of external mycelium pale olivaceous brown, finely verruculose, 1–2 μm wide. Conidiophores mostly single, arising from the external mycelium, simple, erect, dark brown, smooth or very finely verruculose, up to 200 μm long, with numerous conidial scars towards the apex. Conidia subcylindrical, 1–5-septate, 12–170 × 3–4 μm, finely verruculose, hyaline, base truncate with a distinct scar. Leaf spots yellow brown with no distinct margin; external mycelium visible as a darkish, hairy colony on the lower surfaces of leaves.
