Description: Thallus crustose, episubstratic, rimose to weakly rimose-areolate in the thickest parts, <2 mm thick, forming large, 4-7 cm wide patches, with dispersed to crowded, convex, verrucose or rugose, 0.2-0.3 mm wide areoles, esorediate or sometimes with 0.1-0.2 mm wide isidia-like granules bearing distinctly capitate soralia, whitish grey to pale yellowish green, the granules paler than the non-granular parts. Apothecia common, round to irregular in outline, adnate, up to 0.8 mm across, with a scarlet-red to deep rusty red, flat to convex disc and a thin, finally often excluded thalline margin. Proper exciple c. 90 µm thick, with small crystals visible under polarized light; epithecium deep red, encrusted with crystals, K+ blue-violet; hymenium colourless to reddish in upper part, 40-50 µm high; hypothecium colourless, but appearing grey by the presence of small crystals. Asci 8-spored, clavate, with a shallow, uniformly K/I + blue apical dome, lacking a distinct ocular chamber or apical cushion, with spirally arranged spores, Ophioparma-type. Ascospores 3(-4)-septate, hyaline, narrowly fusiform, straight or curved, 25-38 x 3-3.5 µm. Pycnidia black, developing on or among the areoles, with a blue-black, wall reacting K-. Conidia simple, hyaline, bacilliform, 5-8 x 0.7-1 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC+ pale yellow, P-. Chemistry: thallus with usnic, divaricatic and nordivaricatic acids, plus low concentrations of atranorin; apothecia with haemoventosin.Note: the record from Sardinia (samples collected on an old specimen of Juniperus oxycedrus), was the first from Europe of this western North American epiphytic species, which has been later recorded also in Norway (Timdal & Spribille 2026).
