| Thallus in the uppermost bark layers, greenish white, effuse, finely granular. Prothalline lines distinct, dark red-brown. Photobiont in short chains; cells ellipsoidal, 10–16 × 7–10 μm. Ascomata dispersed, rounded, stellate or irregular in shape, usually not distinctly elongate, 0.24–1.80 mm wide, ±level with the thallus or slightly convex, with a dense crimson pruina. Epihymenium 20–40 μm thick, densely inspersed with crimson and, to a lesser extent, colourless crystals. Hymenium 40–50 μm thick, less densely inspersed with crimson crystals than the epihymenium. Hypothecium colourless, 40–50 μm thick. Asci dispersed, globose to subglobose, 4–8-spored. Ascospores in 3 or 4 rows, ellipsoidal to obovate, with 3 transverse septa, 22–38 × 11–16 μm, not constricted at the septa; polar cells often slightly smaller. CHEMISTRY: Pigments K+ purple-orange; containing five unknown pigments |
