Hyphae strongly appressed tothe host surface, crooked, branching alternate toirregular at acute to wide angles, closely reticulate andforming almost solid mycelial mat, cells 38–56x6–8 µm.Appressoria scattered, alternate to unilateral, antrorseto reflexed, curved variously, 26–50 µm long; stalk cellscylindrical, flexuous, usually elongated, usually 8–22 µmlong; head cells ovate, versiform, angulose, entire tolobate, straight to curved, 18–22x14–18 µm. Phialidesfew, mixed with appressoria, conoid to ampulliform, 12–26x4–8 µm.

Hyphae straight to flexuous, branchingmostly opposite at acute angles, loosely reticulate,cells 19–24x4–6 μm. Appressoria alternate, antrorse toclosely antrorse, 12–18 μm long; stalk cells cylindricalto cuneate, 3–7 μm long; head cells ovate, globose,slightly attenuated to truncate at the apex, mostlyentire, rarely sublobate, 9–12x8–10 μm. Phialides mixedwith appressoria, alternate to opposite, ampulliform,16–22x8–12 µm. Mycelial setae scattered to mostlygrouped around perithecia, simple, straight, curved,acute to obtuse at the apex, up to 600μm long.
