Description: Thallus leprose, consisting of a soft mass of soredia-like granules, whitish to usually cream-coloured, sometimes clearly yellowish, usually poorly delimited, always without lobes and without a raised edge. Granules coarse, (80-)100-200(-280) μm in diam., sometimes with short projecting hyphae. Medulla white, very poorly developed to absent. Photobiont chlorococcoid. Spot tests: K- or K+ yellow slowly turning dirty orange, C- or C+ dirty orange, KC- or KC+ yellow to dirty orange, P+ yellow-orange to brownish red, UV-. Chemistry: 4-oxypannaric acid 2- methylester (major), 4-oxypannaric acid (minor to trace), pannaric acid methylester, pannaric acid 2-methylester, pannaric acid and other dibenzofurans (traces).

Note: in niches and fissures of calcareous or dolomitic boulders, but also on soil, mosses and plant debris in dry grasslands, mostly on surfaces sheltered from rain; probably occurring throughout the country.

Substrata: rocks, bark, soil, terricolous mosses, and plant debris

Photobiont: green algae other than Trentepohlia
