Description: Thallus inapparent, not lichenized, but sometimes loosely associated with trentepohlioid algae around the perithecia. Perithecia black, numerous, 0.3-0.5 mm across, circular to ellipsoid, surrounded by a dark fringe, at first immersed, then hemispherical to flattened, 0.1-0.15 mm high, the central ostiole sometimes located in a small papilla. Involucrellum dark brown, c. 30 μm thick, extending beyond the perithecium in a basal fringe, composed of pieces of bark intermixed with greenish-black hyphae; exciple thin, poorly evident, pale throughout; pseudoparaphyses 1-2.5 μm thick; hymenial gel I+ pale orange. Asci 8-spored, clavate, bi- and fissitunicate, with a broad, truncate apical beak. Ascospores 1-septate, hyaline, narrowly fusiform, curved, 24-36 x 2-3.5 μm. Pycnidia back, immersed in the bark. Microconidia simple, hyaline, bacilliform, to 4 μm long; macroconidia simple, hyaline, fusiform-arcuate, c. 25 c 1.5-2 μm. Photobiont absent. Spot tests: K-, C- KC-, P-.
