| Thallus whitish to pale grey, greenish grey or dark brownish grey, dull or slightly glossy, to 10 cm wide, 20–300 µm thick, ±smooth or irregularly areolate and rimose, scabrid, minutely papillose to verruculose, often eroding with age but lacking soredia and isidia, ecorticate or with a poorly differentiated cortical layer 20–30 µm thick. Prothallus absent. Photobiont cells 8–15 µm wide. Apothecia sessile or basally constricted, round to ±irregular, scattered or crowded, 0.1–1.2 mm diam.; disc bright orange-red to red-brown, glossy, ±plane to strongly convex, epruinose; margin thin, often flexuose, soon becoming excluded. Exciple densely inspersed with orange-red K+ reddish purple pigment. Epihymenium 12–15 µm thick, orange-red, K+ purple-red. Hymenium 35–60 µm thick, inspersed with orange K+ reddish purple pigment, densely so in the upper part, faintly pigmented to colourless below. Hypothecium colourless or inspersed with orange K+ reddish purple pigment, 40–100 µm thick; subhypothecium colourless to pale brown, to 15 µm thick, K–. Paraphyses simple or occasionally branched, rather robust, 2–3 µm thick; apices tapered or rounded, not noticeably swollen. Asci 25–38 × 9–12 µm. Ascospores ellipsoidal to fusiform-ellipsoidal, 7.0–14.5 × 2.5–4.0 µm. Conidia filiform, curved or hook-shaped, 10–20 × c. 0.5 µm. CHEMISTRY: Thallus K–, C–, KC–, P–, UV–; containing protolichesterinic and lichesterinic acids or lacking lichen substances. Apothecia K+ reddish purple; containing russulone (major), norrussulone (trace). |
