Description: Primary thallus crustose, grey, white or pale pinkish, thick, areolate, usually with soft, rounded, white, more or less shiny, warty schizidia which are up to 1 mm wide in sterile thalli, 0.1-0.3 mm wide in fertile thalli. Apothecia frequent, globose also when young, often hollow inside, pink, 1-4 mm broad, emarginate or with a narrow margin, brought on erect, subfruticose, smooth, ecorticate, white stipes (podetia), which are 2-5 mm tall and to 3 mm wide. Epithecium with colourless crystals (present also in the hymenium); hymenium 120-140 µm high, K/I+ blue (reaction ephemeral!); hypothecium colourless; paraphyses simple, not anastomosing, only slightly thickened above. Asci 8-spored, unitunicate, cylindrical, thin-walled, slightly thickened above, I+ blue, the tip I+ deep blue, Icmadophila-type. Ascospores hyaline, mainly 1-celled (some 2-celled), fusiform, 10-26 x 2-3 µm. Pycnidia 0.1-0.2 mm across, immersed in warts, mostly laminal, with a colourless wall (brownish near the ostiole). Conidia shortly bacilliform, 3.5-5 x c. 1 µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow-orange, C-, KC+ orange, P+ yellow to orange, UV+ orange; medulla P+ yellow to orange, UV+ orange. Chemistry: baeomycesic acid, and variable amounts of squamatic and barbatic acids and atranorin.
Note: on humid, disturbed clay soil, often in Calluna-heaths, most frequent in upland areas. For further details see Gierl & Kalb (1993).
