Astrothelium subrufescens

Ciri dan struktur

Diagnosis: The new species can be distinguished from the somewhat similar species Astrothelium rufescens (Müll. Arg.) Aptroot and Lücking by the pseudostromata that contain few ascomata. Description: Thallus crustose, corticolous, continuous, 1–9 cm diam., 30–90 µm thick, smooth to uneven, or bullate, olive-green. Algae trentepohlioid. Ascomata perithecia, black, conical to pyriform, 0.6–1.5 mm diam., immersed to erumpent in pseudostromata. Pseudostromata surfaces grey-white or grey-yellow, not concolorous to the thallus. Ostiole apical, black, with whitish surrounding area, 0.1–0.5 mm diam. Ascomata wall carbonized, black, 55–160 μm thick. Hamathecium is clear, not interspersed with oil droplets. Asci cylindrical to clavate, colorless, 85–117 × 13–16 µm. Ascospores eight per ascus, biseriate to irregular, hyaline, fusiform, ends rounded, transversely three-septate, 19–27 × 6–9 µm, lumina diamond-shaped, surrounded by a smooth gelatinous sheath, 1.5–11 μm wide. Pycnidia not seen.
