  Thallus endolithic, continuous or faintly rimose near the perithecia, pale grey to pale greyish green. Algae globose, 6–12 µm diam. Prothallus usually not apparent, occasionally dark brown (not in Australian specimens). Perithecia almost completely immersed in the substratum, 0.3–0.6 mm diam., leaving black pits in the rock following their decay (pits lined with the blackish basal part of the exciple); apex 0.2–0.3 (–0.4) mm diam., plane to slightly convex; ostiole inconspicuous. Involucrellum absent. Exciple 20–35 µm thick, dark brown to black. Centrum 0.25–0.5 mm wide. Periphyses 35–55 µm long. Asci 80–120 × 25–35 µm. Ascospores narrowly to broadly ellipsoidal, 20–48 × 10–25 µm.
  Occurs on limestone in southern S.A. and southern Vic. Also throughout Europe and in North Africa and East Asia; there is a doubtful record from New Caledonia.
