Perithecia semi-immersed to one-third immersed, hemispherical to subglobose, (0.27–) 0.38 (–0.52) mm diam., black; apex rounded; ostiole usually in a shallow 60–100 (–140) µm wide depression. Involucrellum usually contiguous with the exciple, 60–100 µm thick. Exciple 20–30 µm thick, hyaline at the base, darkening towards the apex. Centrum 0.2–0.35 mm wide. Periphyses 30–60 × 1.5–3.5 µm. Asci 90–128 × 26–35 µm. Ascospores elongate-ellipsoidal to broadly ellipsoidal, occasionally subcylindrical or clavate, 26–47 × 11–20 µm.
