Description: Thallus squamulose to areolate-verrucose, grey, lead-grey to almost black in sun-forms, olive-grey when wet, the areoles/squamules crowded, often imbricate, 0.3-1 mm wide, smooth. Cortex paraplectenchymatous, K+ faintly violet; medulla white, without granules. Apothecia zeorine/lecanorine, adnate, 0.5-1.5 mm across, with a yellow-orange to dark orange, flat to convex, epruinose disc, a brown to black (devoid of anthraquinones) proper margin forming a dark excipular ring between disc and thalline margin, and a usually persistent, slightly raised, often lobulate-crenulate thalline margin. Proper exciple of elongate to oval cells, K+ violet; epithecium orange, K+ red; hymenium colourless, 55-75 µm high; paraphyses sparingly branched in upper part, the apical cells slightly swollen, 2-3 µm wide; 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 2-celled, polarilocular, hyaline, ellipsoid, 9-16 x 4-8 µm, the equatorial thickening (“septum”) (2.5-)3-4(-5.5) µm (c. 1/3 of spore length). Pycnidia black, totally immersed. Conidia 4-6 x c. 1 µm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly violet in section, C- or C+ violet, KC-, P-; disc of apothecia K+ red. Chemistry: thallus with the Sedifolia-grey pigment; disc of apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor).
Note: a Mediterranean to xeric subtropical species of base-rich siliceous rocks, often growing with species of Peltula, and starting the life-cycle on other crustose lichens; mostly Mediterranean, but also found, although very rarely, in dry-continental Alpine valleys. For further information see Wetmore (1996). See also note on C. furax. The epithet Callopisma conglomeratum Bagl. predates Lecanora peludella Nyl. (often spelled pellodella). The species is related to Pisutiella conversa (Vondrák in litt.).
