Anamorph: conidiomata pycnidial. Pycnidia initially immersed in the host, becoming superficial, ellipsoidal, 80-125 µm high and 50-90 µm diam., with setae near the ostiole. Setae dark brown, thick- and smooth-walled, 30-70 µm long and 3.5-5 µm diam., 3- to 5-septate, the terminal cell being paler and finely verrucose. Pycnidial wall composed of several layers of polyhedral to subspherical cells, 4-7 µm thick. Conidiophores elongated, filiform, with several septa, hyaline, lining the pycnidial cavity, 4-18 × 1-1.8 µm. Conidiogenous cells enteroblastic, integrated, appearing as very short lateral branches just below each septum of the conidiophores, hyaline, smooth-walled. Conidia hyaline, simple, smooth-walled, ellipsoid, 3-3.5 (-4) × 1.4-1.8 (-2) µm.
