Ciri dan struktur

Diagnosis: The new species can be distinguished from the most related species Astrothelium eustominspersum Aptroot and Oliveira-Junior by the lichexanthone only contained in the thallus. Description: Thallus crustose, corticolous, greenish-grey to olive-green, smooth to uneven, somewhat shiny, continuous, covering areas up to 6 cm diam., 0.2–0.4 mm thick, not surrounded by a prothallus. Algae trentepohlioid. Ascomata perithecia, globose to pyriform, black, 0.15–0.4 mm diam., single to 2–15 aggregated groups immersed in pseudostromata. Pseudostromata surfaces white-grey to brownish, not concolorous to the thallus, raised, rounded to irregular. Ostiole eccentric, fused, black, 0.2–0.6 mm diam. Ascomata wall carbonized, 30–100 μm thick. Hamathecium hyaline, interspersed with oil droplets. Asci cylindrical to clavate, 88–170 × 13–17 μm. Ascospores eight per ascus, biseriate to irregular, hyaline, fusiform, transversely three-septate, 17–28 × 6–8 μm, lumina diamond-shaped, surrounded by a smooth gelatinous sheath, 1–6 μm wide. Pycnidia not seen.
