Synonyms: Pertusaria fallax var. rupicola f. sterilis Garov.; Pertusaria rupicola var. coralloidea (Anzi) Croz.; Pertusaria sulphurea A. Massal. non Schaer.; Pertusaria sulphurea var. coralloidea (Anzi) Jatta

Description: Thallus crustose, episubstratic, rather thick, yellow-ochre to yellowish green, sometimes delimited by a thin, dark prothallus, either mostly sterile and densely covered by subcylindrical, to 0.5 mm thick and to 2 mm high isidia-like papillae containing a pycnidium, or abundantly fertile and verrucose. Apothecia lecanorine, immersed in 0.4-3.0 mm wide, basally slightly constricted thalline warts, crowded and locally fused (2-4) in mutually deformed groups, at first almost perithecioid, but the disc soon expanding to 0.3-0.6(-1) mm, forming a pseudolecanorate, blackish brown, often grey-pruinose disc. Epithecium dark brown to black, K+ violet; hymenium colourless; paraphyses lax, branched and richly anastomosed; hypothecium colourless or yellowish. Asci (4-)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, broadly ellipsoid, 70-110 x 30-50 µm, double-walled, the wall smooth, 10-15 µm thick. Photobiont: chlorococcoid. Cortex : K+ yellow, C+ orange, KC+ yellow-orange, P-. Chemistry: thiophaninic and stictic acids (major), norstictic, and cryptostictic acid (minor or accessory), sometimes with traces of atranorin.
Note: a mild-temperate lichen of siliceous rocks, most frequent in Tyrrhenian Italy near the coast, but also occurring in the mountains. Isidiate and fruiting specimens are often found together, and intermediate specimens are frequent, the isidiate morphs (those with isidioid papillae bearing pycnidia) are better treated at the rank of forma.
Growth form: Crustose
Substrata: rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
