Description: Thallus crustose, fully endolithic, usually covering large surfaces, white to pale grey, smooth or most often with long cracks radiating from some of the perithecia, often bordered from adjacent thalli by a black prothalline line. Upper cortex (lithocortex) densely prosoplectenchymatous, of conglutinated hyphae intermingled with microcrystals; algal layer discontinuous, photobiont cells in clusters; medulla prosoplectenchymatous, without oil cells (macrospheroids) in the lower part. Perithecia completely immersed in the rock and leaving pits when they fall off. Involucrellum absent; excipulum subglobose to broadly pyriform, 0.2-0.45 mm wide, black throughout, the pigment dark reddish brown, K+ dark grey-brown; hymenium colourless, K/I+ blue; hamathecium of periphyses in the ostiolar canal, and short periphysoids in the half upper part of the perithecial cavity. Asci 8-spored, two-layered, fissitunicate, with a thin tholus reacting I-, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (18-)23-27(-29) x (8.5-)10-13(-15) μm. Photobiont chlorococcoid. Spot tests: all negative. Chemistry: no lichen substances.
Note: on limestone, dolomite, and other calciferous rocks, often associated with Circinaria calcarea.
