in Kondratyuk & al., Index Fungorum, 466: 1, 2020. Basionym: Imbricaria demissa Flot. ex Körb. - Syst. Lich. Germ.: 80, 1855
Synonyms: Caloplaca demissa (Körb.) Arup & Grube; Lecanora demissa (“Flot.”) Zahlbr.; Lecanora incusa (Flot.) Vain.; Rinodina castanoplaca (Nyl.) H. Olivier; Squamaria elaeina var. saxicola Beltr.
Description: Thallus crustose-placodioid, episubstratic, firmly attached, pale to dark brown to almost black in sunny situations, often greyish-pruinose in central parts, up to 0.15 mm thick, forming regular to irregular, up to 1 cm wide rosettes, several thalli often merging to cover larger surfaces. Lobes 1-1.5(-2) mm long, (0.1-)0.3-0.5(-0.8) mm wide, flat to weakly convex, divided into 2-3 secondary lobules towards the tips. Soralia mainly in the centre of thallus, laminal, at first punctiform, then irregularly rounded, concave, 0.3-0.5 mm wide, finally sometimes elongated and fissure-like, brownish to brownish green, those in the central parts of thallus often coalescing. Soredia 30-50 μm thick, becoming blastidiate-isidioid, grey-brown to dark brown or brownish green. Cortex 30-40 µm thick, with a brown pigment which dissolves in K forming colourless crystals; medulla white, prosoplectenchymatous. Apothecia not known. Pycnidia rare. Conidia bacilliform to narrowly ellipsoid, 3.5-5 × c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: thallus with vicanicin and caloploicin.
Growth form: Crustose placodiomorph
