Distribution:
Description: Thallus crustose, episubstratic (rarely poorly developed and immersed), grey, epruinose, verrucose. Cortex 11-22 µm thick, consisting of intricately interwoven, gelatinized hyphae. Apothecia immersed in thalline warts, black, (0.3-)0.5-0.7(-1) mm across, the warts constricted or widened at base, epruinose. Mazaedium 0.2-0 4 mm in diam.; proper exciple thin throughout, not or only very slightly thickened at base, 25-34 µm wide laterally, consisting of intricately interwoven, brown, sclerotized hyphae; hypothecium very thin, poorly pigmented. Asci 8-spored, dissolving early, 21-27 x 5-7 µm , with 2-3 seriately arranged spores. Ascospores 1-septate, constricted at septum, soon turning green, then brown, broadly ellipsoid, 20-23 x 10-13 µm, smooth-walled. Photobiont chlorococcoid. Spot tests: thallus K- or K+ weakly reddish brown, C-, KC-, P-, UV-. Chemistry: without lichen substances,
Note: a rare, lignicolous, critical species. It could be confused with rare, rhizocarpic acid-deficient specimens of C. tigillare, which have slightly narrower spores, that are (6-)7-10(-11) µm wide.
