Description: Thallus crustose, very thin, usually endosubstratic in the esorediate parts, whitish grey to dark grey, continuous, sorediate, forming regular to irregular, up to a few cm wide patches, unzoned and without a distinct prothallus. Soralia whitish or faintly yellow-white, mostly discrete, sometimes concentrically arranged, more or less orbicular and excavate-ulcerose to flat, rarely somewhat convex, to 0.5(-0.8) mm across. Soredia mostly farinose, up to 40 μm in diam., sometimes gathered into larger, rounded to elongate up to 80 μm wide consoredia. Apothecia rare, lecanorine, immersed in thalline warts, usually 1 per wart, with a brown-black, epruinose disc and a prominent, sometimes sorediate, often finally excluded thalline margin. Epithecium olive-green, K+ violet; hymenium and hypothecium colourless. Asci 8-spored, broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, subglobose to broadly ellipsoid, 10-14 x 7-11 µm, the wall c. 1 µm thick. Pycnidia convex, the ostiolum blackish, becoming widely gaping, the pigment green, K+ violet. Conidia bacilliform, 4-6 x c. l μm. Photobiont chlorococcoid. Spot tests: soralia K+ yellowish then dirty brown-red, C-, KC- or KC+ yellow-red, P+ orange-red to rust-red, UV+ faintly whitish blue. Chemistry: fumarprotocetraric acid (major), protocetraric acid (trace).
Growth form: Crustose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
