in Frolov & al., J. Syst. Evol. 59, 3: 468, 2020. Basionym: Caloplaca soralifera Vondrák & Hrouzek - Graphis Scripta, 18: 8, 2006.
Synonyms:
Distribution: N - TAA (Thor & Nascimbene 2007).
Description: Thallus crustose-areolate to subsquamulose, episubstratic, dark to pale grey, often whitish-pruinose. Areoles flat to convex, 0.2-0.8 mm wide, (50-)150-250 μm thick, with dark grey to violet-grey marginal soralia which, albeit rarely, may finally cover the whole thallus surface. Soredia dark violet grey, (22-)26-42(-50) μm in diam. Cortex either inconspicuous, almost completely obscured by colorless crystals insoluble in K and soluble in N, or well-developed, up to 35 μm thick, paraplectenchymatous, pale greyish toward the surface (K+, N+ violet), with a 5–8.5 μm thick epinecral layer; algal layer continuous, without crystals. Apothecia zeorine, 0.2-0.7(-1) mm across, with an orange to brownish orange disc, a yellow to orange proper margin, and a pale grey, usually white-pruinose thalline margin. Thalline exciple with abundant algae, indistinctly corticate, with colourless crystals insoluble in K and soluble in N; proper exciple well-developed, of long and narrow, thin-walled cells; epithecium brownish orange, K+ red; hymenium colourless, 68–77(−110) μm high; paraphyses sparingly branched and rarely anastomosing, 1.5-3 μm thick in middle and lower parts, the apical cells swollen, up to 6.5 μm wide; hypothecium colourless, often inspersed with oil droplets. Asci 8-spored, clavate, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 11-15(-17) x 4-8(-10) μm, the equatorial thickening (“septum”) (3.5-)4-5.5(-7.5) μm. Pycnidia immersed, the wall grey in section, K+ violet. Conidia ellipsoid, 2.5–3.5 x c, 1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ violet-red, C- (epithecium weakly and slowly C+ orange-red), P-. Chemistry: low amounts of sedifolia-grey pigment in thallus and especially pycnidial walls; apothecia with parietin (major), fragilin, emodin, emodial, emodic acid and 7-chloremodin (minor).
Note: a species with a grey but often whitish pruinose, areolate thallus, the areolae with marginal soralia, found on concrete, mortar or siliceous pebbles in manured sites; hitherto known especially from eastern Europe, but probably more widespread, at least in the continental Alpine valleys.
Growth form: Crustose
