[ISE40245], Brazil, Pará, Vila Nazaré, 80 km N of Dom Eliseu, 120 m, 3°53’56’’ S, 48°05’44’’ W, on tree bark in primary tropical lowland rain forest. Leg. M. Cáceres & A.Aptroot (no 40245), 29.10.2016, det. A. Aptroot, 2016. ISOTYPE. Thallus dull, up to 0.2 mm thick, olivaceous green, not surrounded by a prothallus. Ascomata globose to pyriform, 0.2–0.4 mm diam., deeply immersed in and below pseudostromata, in groups of 6–25. Pseudostroma not much differentiated from the thallus, c. 1–3 mm diam., ellipsoid to elongated or branched, internally pigmented with bright yellow crystals. Ostioles eccentric, fused, black, surrounded by a c. 0.1 mm wide ochraceous ring. Hamathecium not inspersed, IKI–. Ascospores 8/ascus, hyaline, 6–7-septate, 32–35 × 7–8 μm, longellipsoid, without distinctly thickened septa, not surrounded by a gelatinous sheath. Pycnidia not observed. Chemistry: Thallus UV–, C–, K–, KC–, P–; pseudostroma inside with yellow crystals, UV–, C–, P–, K+ blood red. TLC: An anthraquinone, probably parietin.
