in Zhao Xin & al., Fungal Divers., 78: 301, 2016. Basionym: Placodium garovaglii Körb. - Parerga Lichenol.: 54, 1865.
Synonyms: Lecanora cascadensis H. Magn.; Lecanora garovaglii (Körb.) Zahlbr.; Lecanora nevadensis H. Magn.; Placodium peruvianum Müll. Arg.; Squamaria garovaglii (Körb.) Anzi
Description: Thallus crustose-placodioid, episubstratic, areolate and 0.5-2(-3) mm thick in central parts, rather loosely attached, epruinose to patchily pruinose, greenish yellow to grey-yellowish green, often darker at lobe-tips and grey-green in central parts, forming rosettes to 6 cm and more in diam., but often several thalli merging to cover larger surfaces. Central areoles contiguous, 0.3-1.5 mm wide, slightly to strongly convex; marginal lobes 4-8 mm long, 0.5-1.5 mm wide, strongly and irregularly convex, sinuous, often with transversal cracks, partially hollow inside. Upper cortex 15-50 µm thick, inspersed with yellowish granules soluble in K; medulla white, very loose, often becoming hollow in center. Apothecia lecanorine, sessile and constricted at base, 0.7-2 mm across, with a reddish brown to finally rarely blue-black, flat, epruinose disc and a 0.1-0.2 mm thick, finally excluded thalline margin, with a conspicuous parathecial ring. Thalline exciple corticate, paraplectenchymatous, the algal layer extending below the hypothecium; proper exciple colourless, prosoplectenchymatous, 15-25 µm thick; epithecium pale orange to dark brown, inspersed with fine granules soluble in K and insoluble in N, 10-25 µm high; hymenium colourless, 50-65 µm high, I+ blue; paraphyses coherent, with clavate, 2-3 mm wide apical cells; 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 broadly ellipsoid, 7-12 x 5-7 µm. Pycnidia immersed, dark around the ostiole. Conidia filiform, (20-)25-35 µm long. Photobiont chlorococcoid. Spot tests: K- or K+ pale yellow, C-, KC+ pale yellow, P-. Chemistry: cortex with usnic acid (major), placodiolic and/or isousnic acids (minor); medulla usually with zeorin and unidentified terpenoids.
