Mycobank MB 517743
Thallus 3–5 cm wide or aggregated in larger colonies, crustose, distinctly areolate, dull pink, dirty whitish pink to pinkish orange or dull brownish orange; areoles 0.3–0.8 mm wide, somewhat smaller in the centre, but 1.0–1.5 mm wide in the peripheral zone, angular or more or less rounded with somewhat raised and slightly darker coloured edges, upper surface dull pink. Apothecia (0.2–)0.3–0.6 mm diam., immersed at first then slightly raised above the level of the areole, usually 1–3(–5) per areole, rounded to distorted by mutual pressure, rarely aggregating in irregular, compound apothecia, often with a very thin, obscure, paler pinkish thalline rim ca. 40–50 µm wide; disc plane to subconvex, dark reddish brown to dark brick orange, sometimes with a sparse whitish pruina; hymenium ca. 50 µm high; uppermost cells of paraphyses swollen, to 4 µm diam.; asci (7–)8–spored, very small, 27–30(–40) x 12–15 µm, various sized ascospores sometimes present in the same ascus; ascospores broadly ellipsoid, slightly widened at the septum, (8–)9–11(–14) x (5.5–)6–7 µm in water and (9–)10–13(–14) x 7–9 µm in K, septum 3–5 µm wide in water and 3–5(–6) µm wide in K. Secondary chemistry: parietin (major), gyrophoric acid (major), ovoic acid (minor/trace), lecanoric acid (minor), xanthorin (minor), erythroglaucin (minor).
