  Thallus endolithic to epilithic or epiphloeodal, rimose to areolate, greenish white, pale grey or pale or medium grey-green, matt, smooth, 50–150 (–250) µm thick, ecorticate; prothallus not apparent. Algae Trentepohlia; cells 7–23 × 7–17 µm. Perithecia superficial, subglobose to globose, 0.4–0.8 (–1.4) mm diam., often overgrown almost to the apex by a thalline layer with a rugose to verrucose surface; apex plane or rounded, dark grey to black; ostiole inconspicuous or in a shallow depression. Involucrellum dark brown, grey-black or black, extending from the apex to the base of the perithecium as a 20–40 µm thick K+ reddish brown layer, subtended by fungal hyphae, algal cells and crystals. Exciple 20–30 µm thick, hyaline to pale yellow-brown. Centrum 0.18–0.55 mm wide. Asci elongate-cylindrical, 103–141 × 7–10 µm. Ascospores fusiform to narrowly ellipsoidal, 3-septate, 19–23 × 3–6 µm; perispore thin or not apparent. Pycnidia semi-immersed to almost completely immersed, 60–180 µm diam. Conidia narrowly ellipsoidal, bacilliform or fusiform, 2.5–4 × 1–2 µm.
  Occurs in south-western W.A., south-eastern S.A., southern Vic. and Tas.; grows on limestone, basalt and bark in coastal areas. Also in South Africa and New Zealand.
