Prothallus absent. Thallus white, grey or pale brown, endolithic, rarely epilithic (two sequenced specimens), thin, continuous, algal cells 5-8 mm, occasionally (three sequenced specimens) contiguous conspecific thalli separated by dark brown lines, 0.13-0.22 mm wide. Perithecia 0.13-0.40 mm in diam., (1/4-)1/2-1-immersed, leaving shallow to deep pits in the rock, few perithecia occasionally not leaving pits, often surrounded by a thalline collar, sometimes thinly thalline covered; 50-140 perithecia/cm2. Ostiole usually inconspicuous, pale or dark, plane or depressed, ca. 20-50 mm wide. Involucrellum absent or apical, short, rarely covering half of the exciple (two sequenced specimens), (40-)50-80 mm thick, appressed to the exciple or diverging from the exciple. Exciple 0.20-0.35 mm in diam., wall dark brown or black, ca. 27-40 mm thick, apex thickened to ca. 50-100 mm thick if the involucrellum is absent. Periphysoids ca. 30-50(-60)
