Ciri dan struktur
Diagnosis: The new species was similar to Astrothelium phlyctaena (Fée) Aptroot and Lücking but can be distinguished by interspersed hamathecium, and UV-negative pseudostromata. Description: Thallus crustose, corticolous, continuous, grey-green or light green, 2–4 cm diam., 300–600 µm thick, smooth to uneven. Algae trentepohlioid. Ascomata perithecia, conical to pyriform, elongated, black, 0.15–0.40 mm diam., immersed to erumpent, single or aggregated in pseudostromata. Pseudostromata surfaces grey-white or grey-yellow, not concolorous to the thallus, raised, top flattened. Ostiole apical, appearing as blackish dots, black, 0.1–0.3 mm diam. Ascomata wall carbonized, black, 32–72 μm thick. Hamathecium hyaline, interspersed with oil droplets. Asci cylindrical to clavate, colorless, 75–120 × 12–18 µm. Ascospores eight per ascus, biseriate to irregular, hyaline, fusiform, ends rounded, transversely three-septate, 18–29 × 6–10 μm, lumina diamond-shaped, surrounded by a smooth gelatinous sheath, 4–18 μm wide. Pycnidia not seen.
