Type: Foliicolous Fungi; Description: Mycelium both internal and external. Hyphae of internal mycelium smooth, hyaline, 1–2 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 single or in small groups, arising from the external mycelium, simple or with 1–2 branches, erect, dark brown, smooth, up to 110 μm long, with numerous conidial scars towards the apex. Conidia cylindrical to elliptic, 0-septate, 5–12 × 1–3 μm, finely verruculose, pale olivaceous brown. Leaf spots as such are not formed, but the external mycelium appears as a darkish colony on the lower surfaces of leaves.
