Parerga Lichenol.: 368, 1865. Basionym: Sagedia parameca A. Massal. - Symmicta Lich.: 97, 1855.
Synonyms: Leptorhaphis xylographoides Norman; Spermatodium paramecum (A. Massal.) Trevis.; Verrucaria parameca (A. Massal.) Stizenb.
Description: Thallus inapparent, doubtfully lichenized, consisting of dark brown to greenish black hyphae. Perithecia black, shiny, (0.15-)0.3-0.4(-0.6) mm across, ellipsoid, at first immersed, then hemispherical to flattened and c. 0.1 mm high, the central ostiole sometimes located in a small depression. Involucrellum greenish black, c. 15-18 μm thick, extending beyond the perithecium in a distinct, 170-300 μm wide basal fringe composed of pieces of bark intermixed with greenish-black hyphae; exciple thin, poorly evident, pale throughout; pseudoparaphyses 2-2.5(-3) μm thick; hymenial gel I+ pale blue. Asci 8-spored, cylindrical-clavate, bi- and fissitunicate, with a broad, truncate apical beak. Ascospores 1-septate, hyaline, narrowly fusiform, arcuate or sigmoid, 30-46 x 2-4 μm. Photobiont absent. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
