[Sipman26957], Venezuela, Estado Bolvar, Cerro Guaiquinima, in central part of upper plateau, along Rio Carapo (near camp 3-nuevo). Rocky slope with low forest in deep clefts and along the river. 5°49’ N, 63°32’ W, 800 m. Leg. H. Sipman (no 26967), 11.02.1990. HOLOTYPE Thallus corticate, smooth, bullate, somewhat shiny, c. 0.2 mm thick, yellowish orange, intermixed with patches of a grey prothallus. Ascomata globose, 0.3–0.5 mm diam., in groups of 2–15 in lines or in irreglar groups, witha brown surface with orange pruina, different from the thallus, distincly raised above the thallus. Ostioles apical, not fused, flat to concave. Hamathecium not inspersed. Ascospores 8/ascus, hyaline, 3-septate, 20–25 × 6–9 μm, lumina partly diamond-shaped, IKI-. Chemistry: thallus UV-, ascomata UV+ red, yellow pigment on ascomata K+ blood red. TLC: an anthraquinone, probably parietin.
