in Poelt & Leuckert, Nova Hedwigia, 52: 56, 1991.
Synonyms:
Distribution: N - Frl (Tretiach & Hafellner 2000), TAA.
Description: Thallus crustose, episubstratic, areolate-verrucose, pale to dark yellowish brown, often delimited by a black prothallus, forming orbicular patches to 1-2 cm across on the thalli of Aspilidea myrinii. Areoles contiguous, strongly convex to subpedicellate, 1-3 mm wide. Cortex 30-80 µm thick, with a brown upper layer overlain by a colourless epinecral layer; medulla white, I-. Apothecia not always present, lecanorine, at first immersed, later sessile, up to 1 mm across, with a chestnut brown to dark brown, flat to slightly convex disc, and a thin, entire, finally excluded thalline margin. Thalline exciple eucorticate; proper exciple thin, brownish in outer part, colourless within; epithecium olive-brown; hymenium colourless, 45-70 µm high, I+ blue; paraphyses coherent, 1.5-2 µm thick in lower part, pale brown at tips; hypothecium colourless. Asci 8-spored, clavate, approaching the Lecanora-type, with a well-developed amyloid tholus and a distinct, non-amyloid axial mass. Ascospores 1-celled, hyaline, oblong-ellipsoid to oblong, blunt at both ends, 8-12(-15) x (4-)5-7 µm. Pycnidia rare, immersed, dark around the ostiole. Conidia filiform, curved, 15-31 x 0.5-0.71 µm. Photobiont chlorococcoid. Spot tests: (best observed in sections) K- or K+ yellow turning red (needle-like crystals), C-, KC-, P+ yellow or orange, UV-; apothecial margin always K+ yellow turning red. Chemistry: norstictic acid.
Note: on acid siliceous rocks near and especially above treeline; probably much more widespread in the Alps. The species does not belong to Protoparmelia s.str.
