in Arup & al., Nord. J. Bot., 31: 72, 2013. Basionym: Lecanora subbracteata Nyl. - Flora, 66: 534, 1883.
Synonyms: Caloplaca subbracteata (Nyl.) Lettau; Fulgensia subbracteata (Nyl.) Poelt
Description: Thallus crustose-placodioid, episubstratic, yellow to orange-yellow, sometimes yellowish-white-pruinose, the central parts verrucose-areolate, forming orbicular to irregular, to 3-4 cm wide, often confluent rosettes. Lobes 0.5-1 mm broad and to 3 mm long, flattened, contiguous, radiating from the central part of thallus, which is densely covered in flattened, scale-like, often elongate schizidia. Cortex paraplectenchymatous, 20-50 µm thick, including an up to 40 µm thick epinecral layer; medulla white, 40-135 µm thick. Apothecia rare, lecanorine, sessile, 0.5-1.2 mm across, with an orange to brownish-orange, flat, smooth disc, and a thin, orange-yellow margin which at maturity separates into an internal, darker and thinner proper margin, and an external, paler thalline margin. Epithecium orange-brown, K+ purple-red; hymenium colourless, 60-70 µm thick; hypothecium colourless. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 1-celled, hyaline, ovoid to slightly pyriform, thin-walled, 9-12 x 3.5-5 µm. Pycnidia orange-yellow, immersed. Conidia narrowly ellipsoid. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-, UV+ pale orange. Chemistry: fragilin dominant, with smaller amounts of emodin and parietin and other anthraquinones (minor).
Growth form: Crustose placodiomorph
Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
