Description: Thallus leprose, consisting in a thick and soft, uneven-folded mass of soredia-like granules, bluish white to pale blue-grey, usually well-delimited, the margin sometimes indistinctly lobed, but without raised edges. Granules mostly coarse, up to 60-120 μm in diam., with a loose surface but without projecting hyphae. Medulla very thin, poorly evident. Lower surfaces folded, white to yellowish brown, easily detached from the substrate. Photobiont chlorococcoid. Spot tests: K-, C+ red, KC- or KC+ red, P-, UV+ bright bluish white. Chemistry: divaricatic acid, nordivaricatic acid (major, rarely trace), zeorin (major to minor).
