| Thallus yellow to orange or whitish, with rusty brownish patches, lacking pseudocyphellae, corticate. Ascomata simple, subglobose, erumpent from the substratum, often partly or almost completely covered by the thallus, c. 0.4–0.6 mm diam. Ascomatal wall lacking crystals, to 100 μm thick; ostiole apical, pale to brown. Hamathecium not inspersed with oil droplets, IKI+ orange. Ascospores 8 per ascus, irregularly biseriate, submuriform, with c. 4 rows of 2–4 locules, ellipsoidal, with rounded ends, grey, 12–25 × 8–13 μm; lumina mostly rounded to slightly angular. CHEMISTRY: Thallus and, frequently, apothecia with yellow to orange, UV+ red and KOH+ violet anthraquinone. Its chemistry was elucidated by J.A.Elix (in P.M.McCarthy, Lichenologist 32: 31–32, 2000). |
