Ascomata solitary to somewhat aggregate but not pseudostromatic, with apical, separate ostioles, 1–1.3 mm diam, erumpent, covered by thallus except for the broad, dark ostiolar area surrounded by a thin, irregular whitish rim, darkening when dry. Hamathecium inspersed. Ascospores 4 per ascus, muriform, with 9–11 transverse and 3–4 longitudinal septa per segment, with the distinct diamond-shaped lumina and with a pronounced median septum, ellipsoid to fusiform, 100– 110 × 24–30 µm, IKI+ blue.</p> <p>Chemistry: Secondary substances absent; thallus surface UV-, K-, medulla K-; ascomata surface UV-.</p> <p>Amyloid ascospores are comparatively rare in the genus Astrothelium (Aptroot &amp; Lücking 2016). Among species with muriform ascospores and lacking secondary compounds, the most similar is A. amylosporum Flakus &amp; Aptroot, which differs by its larger ascospores (125–170 ×27–40 µm) occurring in numbers of 8 per ascus and in the fully exposed, brown-black ascomata ((Flakus et al. 2016). Astrothelium bullatum Flakus &amp; Aptroot forms lateral ostioles and the ascomata are fully immersed between bullate thallus portions (Flakus et al. 2016). Astrothelium palaeoexostemmatis Sipman &amp; Aptroot is overall similar to the new species, including ascospore size, but the ascospores are richly muriform, with numerous small cells and thin septa and walls, not displaying diamond-shaped lumina (Aptroot et al. 2019). Both A. flavoduplex Aptroot &amp; M. Cáceres and A. ochroleucoides Aptroot &amp; M. Cáceres deviate by producing lichexanthone (UV + yellow); A. flavoduplex differs further in the strongly pseudostromatic ascomata covered with yellow-orange pigment and the longer ascospores (110–350 × 20–27 µm), whereas in A. ochroleucoides, which agrees with A. mordonialensis in ascospore number and size (80–115 × 15–24 µm), the pseudostromatic ascomata are exposed and brown-black (Aptroot &amp; Cáceres 2016). Two similar species, but with non-amyloid ascospores, are A. tetrasporum Aptroot &amp; M. Cáceres and A. alboverrucum (Makhija &amp; Patw.) Aptroot &amp; Lücking: the first has larger ascospores (145–175 × 30–35 µm), bullate thallus, and ascomata covered by thallus except the protruding ostiole, whereas the former specie also has larger ascospores (85–170 × 23–33 µm) and its ascomata are hemispherical with a whitish cover (Aptroot &amp; Lücking 2016).</p> <p>Additional specimen examined: COLOMBIA.

Only one other species of Astrothelium is known with a combination of pigments and amyloid, muriform ascospores, namely A. flavoduplex. It deviates by producing lichexanthone (UV + yellow) and by the strongly pseudostromatic ascomata covered with with yellow-orange pigment, as well as the longer ascospores (110–350 × 20–27 µm). A morphologically similar species but with I-negative ascospores is A. vezdai (Makhija &amp; Patw.) Aptroot &amp; Lücking, which has larger and much broader ascospores (80–175 × 25–50 µm) and the ostiolar pigment is orange rather than yellow (Aptroot &amp; Lücking 2016).</p> <p>Additional specimen examined: COLOMBIA.
