Description: Thallus crustose, thinly episubstratic, continuous, granulose-farinose, white to pale pinkish grey, the colour rapidly fading in the herbarium, sometimes poorly visible. Perithecia globose, 0.4-0.5(-0.7) mm across, pale pink to pinkish white, immersed in thalline warts, not flattened but with a punctiform, depressed, darker ostiole. Exciple colourless, of short-celled hyphae, with stiff periphyses around the ostiole; hymenium colourless, I+ blue-green, rapidly turning reddish-brown; paraphyses simple, flexuose, not anastomosing, not apically thickened, free. Asci 8-spored, unitunicate, narrowly cylindrical, tapering apically, without apical thickening or apparatus, with uniseriately arranged spores. Ascospores muriform, hyaline, broadly ellipsoid, (20-)22-25(-28) x 12-14(-16) μm, with a thin, often inapparent perispore. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mainly Mediterranean-Atlantic lichen found on calcareous rocks, over soil and moribund bryophytes in shaded-humid situations.
