Description: Thallus leprose, episubstratic, whitish to cream-coloured, clearly delimited, usually rosette-forming, often falling off in the central parts, consisting of a soft mass of soredia-like, up to 200 µm wide granules. Medulla white, well-developed and thick. Apothecia extremely rare, lecanorine, partly immersed to almost superficial, mostly 0.5-1 mm across, with a pinkish, pruinose disc reacting C+ and KC+ yellow and a more or less distinct, sorediate thalline margin.
