Hyphae straight to substraight, branching opposite alternate at acute to wide angles,loosely to closely reticulate, cells 11-24 x 4-7 µm. Appressoria opposite alternate, antrorse, subantrorse to retrorse, 8-15 µm long; stalk cells cylindrical to cuneate, 2-6 µm long; head cells ovate, globose, entire to angular, straight to curved, 6-11 x 6-8 µm. Phialides few, mixed with appressoria, opposite to alternate, ampulliform, 9-16 x 4-7 µm. Mycelial setae simple, straight, acute, dentate to furcate at the tip, up to 350µm long. Perithecia scattered to grouped, up to 196µm in diameter; ascospores obovoidal, 4-septate, slightly constricted at the septa, 25-37 x 8-13 µm.
