Description: Lichen. Thallus crustose, warted-areolate to rimose, sometimes endosubstratal, esorediate; areoles moderately to strongly convex, sometimes irregularly wrinkled, av. diam. 0.15-0.20, max. siam. 0.35-0.50 mm, surface greenish-yellow to ochre or brownish gray, matt. Apothecia rounded or slightly deformed in outline, rarely flexuose, single or in groups, sessile with constricted base, av. diam. 0.50-0.65 mm, max. diam. 0.9-1.5 mm; disc orange- or red-brown to almost black, flat to weakly convex, finely whitish or bluish pruinose, matt; margin prominent in young apothecia, persistent though usually more flat in older apothecia, yellowish beige, matt, weakly wrinkled or knobby. Amphithecium corticate, laterally 90-100 µm, basally 100-125(-210) µm wide, medulla with irregularly entangled, short celled hyphae with lumina 1-2 µm wide, cortex 5-10 µm above, 20-35 µm below, of strongly gelatinized anticlinally arranged hyphae with 1.5-3.0(-3.5) µm wide lumina; hypothecium 45-100 µm high, colorless; subhymenium 20-60Â µm high; hymenium 50-60 µm high, colorless to pale yellowish, often with orange-brown to ochre, granular stripes; epihymenium 5-15 µm high, orange- to red-brown, granular; paraphyses simple or apically weakly branched and anastomosing, with 0.7-1.0 µm apically 1.2-2.0(-2.5) µm wide lumina, apical cells often with brown walls. Ascospores colorless, simple, (9.0-)9.8-11.6(-13.0) âš (4.0-)4.9-5.6(-6.0) µm. Pycnidia not seen (Printzen 2001, p. 393).
