Hi!
Anyone has another suggestion regarding genus for this species? Perithecia c. 300 µm long, sometimes slightly longer than wide, at first immersed, later shallowly emergent, black, ostiole lateral. Hamathecium of narrow, parallel-sided filaments, branched and anastomosing above. Asci cylindrical, c. 110 × 10 µm, wall thickened near apex, spores uniseriate. Ascospores 1-septate, brown, 13-18 × 7-8 µm, 1.9-2.3 times as long as wide, cells equal in size, wall thin, surface verruculose. Photobiont apparently absent.
M. lateralis, from Norfolk Island in the Pacific (Lichenologist 37(4): 307-311) has larger, more elongated, constricted spores, and more prominent perithecia.
