in Kondratyuk & al., Acta Bot. Hung., 61, 1-2: 158, 2019. Basionym: Patellaria varia Hoffm. - Descr. Adumbr. Pl. Crypt. Lich., 1: 102, 1790.
Synonyms: Lecanora subvaria Nyl.; Lecanora varia (Hoffm.) Ach.; Lecanora varia var. denudata Bagl.
Description: Thallus crustose, episubstratic, coarsely granulose, rimose-areolate to warted, ecorticate, yellowish green to ochraceous green, more rarely greenish grey, without a distinct prothallus, the areoles irregular in outline, 0.15-0.3(-0.5) mm wide, weakly convex. Apothecia lecanorine, round to irregular in outline, sessile and constricted at base, 0.4-1.5(-2) mm across, urceolate when young, with a yellowish green to orange-brown, flat, dull, often white-pruinose disc and a prominent, often inrolled, sinuous, persistent thalline margin. Thalline exciple corticate, the cortex 25-80 µm thick laterally, 90-150 µm near base, the hyphae with 1.5-2.5 µm wide lumina, the medullary part rich in algae; epithecium colourless to pale brown, 5-15 µm high, with many small yellow-brown granules soluble in K; hymenium colourless, 50-90 µm high; paraphyses simple or sparingly branched and anastomosing, 1.5-2 µm thick at mid-level, the apical cells hardly swollen; hypothecium colourless in upper part, pale yellow in lower part, 30-40 µm high. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (8-)10-12(-14) x 4-7(-9) µm, 2.1-2.5 times as long as wide. Conidia thread-like, often curved, 12-22 µm long. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly yellow, C-, KC- or KC+ pale yellow, P+ bright yellow, UV+ dull orange. Chemistry: usnic, psoromic and 29-O-demethylpsoromic acids, sometimes with additional diffractaic acid.
