Description: Thallus crustose-placodioid, episubstratic, forming continuous, irregular, up to 8-10 cm wide patches, the central parts glaucous grey-green, the marginal lobes up to 1 mm wide, white-pruinose at margins. Central part of thallus with raised lobules producing blastidia or breaking into soralia-like structures. Apothecia infrequent, lecanorine, up to 1.5 mm across, with an initially flat, then strongly convex, brown, pruinose or epruinose disc, and crenulate, then often excluded thalline margin. Epithecium brownish; hymenium colourless, 60-70 µm high, K/I+ blue; paraphyses simple, coherent; hypothecium colourless, 80-100 µm high. Asci 8-spored, cylindrical-clavate, with a K/I+ blue outer coat and a K/I+ uniformly blue apical dome, approaching the Catillaria-type. Ascospores (0-)1-septate, hyaline, narrowly ellipsoid, (10-)14-18 x 2.5-4 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla C-, K-, KC-, P-. Chemistry: medulla with terpenoids and unidentified substances, rarely with atranorin.
Note: on calcareous rocks in open to sheltered situations; for further details see Guttová & al. (2014).
Growth form: Crustose placodiomorph
Substrata: rocks
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)
