in Zhao Xin & al., Fungal Divers., 78: 301, 2016. Basionym: Lichen peltatus Ramond in Lamarck & de Candolle - Fl. Franç., éd. 3, 2: 377, 1805.

Synonyms: Lecanora peltata (Ramond) Steud.; Lecanora rubina var. heteromorpha Ach.; Psoroma concinnum Bagl. & Carestia; Rhizoplaca peltata (Ramond) Leuckert & Poelt

Distribution: N - Piem (Isocrono & al. 2004), VA (Valcuvia 2000).

Description: Thallus foliose-umbilicate, usually monophyllous, up to 3 cm wide, entire to coarsely crenate or lobulate, often with down-rolled margins. Upper surface greenish yellow to yellowish grey, turning orange-brown in the herbarium, continuous to cracked, sometimes partially pruinose; lower surface yellowish brown, often bluish-black near edges, more or less strongly cracked towards center, erhizinate, attached by a central holdfast. Apothecia lecanorine, usually abundant, 1-5 mm across, immersed to broadly adnate, finally subsessile, with a concave to finally slightly convex, orange yellow to yellowish brown disc, and a smooth to coarsely crenate, persistent thalline margin. Epithecium brown, densely inspersed with crystals penetrating into the upper part of the hymenium; hymenium colourless; paraphyses coherent, clavate, the apical cells clearly swollen; hypothecium colourless. Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid to subglobose, 8-13 x 5-8 µm. Pycnidia dark, immersed. Conidia thread-like, 20-40 µm long. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow turning red, C-, KC+ yellowish, P+ orange, UV-. Chemistry: upper cortex with usnic and norstictic acids; medulla with zeorin, and variable amounts of psoromic, lecanoric, or hypoprotocetraric acids.

Note: a chemically variable species also known from Africa, Asia, and North America, found on exposed siliceous rocks above treeline.
