Description: Thallus crustose-placodioid, episubstratic, orange-yellow, closely attached, forming regular rosettes to 3.5 cm diam. Lobes 0.5-2 mm long, 0.5-1.2 mm wide, adjacent, often pruinose, the central ones with marginal or terminal, lip-shaped to capitate, concolorous soralia bearing minutely granular soredia. Cortex cellular, 20-40 µm thick, with granules insoluble in K; medulla white, prosoplectenchymatous. Apothecia not always present, adnate, 0.4-1 mm across, orange, with a persistent, slightly raised, thick thalline margin. Epithecium orange, K+ red; hymenium colourless; paraphyses with swollen apical cells which are 2-6 µm wide; hypothecium colourless. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, thin-walled, 10-16 x 5-8 µm, the septum thin, 1.5-3 µm. Pycnidia immersed, the ostiole orange. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin, fallacinal, emodin, and teloschistin.
Note: a temperate, somehow subcontinental species found on calciferous substrata, especially on mortar walls, not common in most of Italy, perhaps because of its subcontinental character, but abundant, and locally extremely abundant in some dry Alpine valleys, and along the eastern slopes of the Apennines, mostly on walls in small villages, much rarer in natural habitats. The record from Venezia Giulia is at Rocca di Monrupino near Trieste, that from Friuli in the surroundings of Tarcento (UD). For further details see Gaya & al. (2001).
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)
Subcontinental: restricted to areas with a dry-subcontinental climate (e.g. dry Alpine valleys, parts of Mediterranean Italy)
