Description: Thallus squamulose to areolate-verrucose, olive-grey to almost black in sun-forms. Squamules crowded, often imbricate, 0.3-1 mm wide, smooth. Cortex cellular; medulla white, without granules. Apothecia zeorine/lecanorine, adnate, 0.5-1.5 mm across, with an orange, flat, 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, 55-70 µm high; paraphyses sparingly branched in upper part, the uppermost cells slightly swollen, 2-3 µm wide; hypothecium colourless. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, 9-16 x 4-8 µm, the septum (2.5-)3-4(-5.5) µm thick (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+ violet, 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 predates Lecanora peludella (often spelled pellodella). The species is related to C. conversa (Vondrák in litt.).
