Synonyms: Catillaria alba Coppins & Vězda; Coppinsidea alba (Coppins et Vězda) S.Y. Kondr., Farkas & Lőkös
Description: Thallus crustose, very thin, effuse, usually poorly evident. Apothecia biatorine, round, 0.15-0.4 mm across, white to pale brown or pale pinkish brown, with a strongly convex, often pruinose disc, without a distinct margin. Proper exciple colourless, poorly developed, of conglutinated, radiating, thick-walled hyphae; epithecium pale yellow-orange, with minute crystals dissolving in K; hymenium colourless, 25-35 μm high; paraphyses simple or sparingly branched in upper part, 1-1.5(1.7) μm thick at mid-level, the apical cells up to 3 μm wide; hypothecium colourless. Asci 8-spored, clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I– apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by an I+ red-brown, K/I+ blue outer layer, the ocular chamber relatively small, Biatora-type. Ascospores 1-septate, hyaline, (6.5-)8-10(-11.5) x 2.3-3 μm. Pycnidia conspicuous, sessile to short-stalked, white-pruinose, 80-120 μm across, 80-150 μm high. Conidia 1-celled, hyaline, bacilliform, 3-4 x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV-. Chemistry: unknown, probably without lichen substances.
