Index Fungorum Number: 515959                   Faceoffungi Number: N/A

Saprobic, Sexual morph: Ascomata: 260–400 µm high, 775–950 µm wide, 450–535 µm thick, broadly oblong with flat top in frontal view, conoidal to truncate in sagittal section, elongated, laterally compressed, developing on a thin black stromatic crust, at first immersed, later erumpent by removal of the covering host tissue, opening with an elongated cleft–like ostiolum at the flattened top, epapillate, carbonaceous, black, gregarious. Peridium: 60–150 µm thick at the sides, 5–18 µm at the base, encrusted with melanin particles, thick–walled cells forming a textura angularis, cells of the host are enclosed in the lower half of the peridium. Ostioles: 10–60 µm wide, ostiolar canal filled with hyaline periphyses, 1.8–2.2 µm thick. Pseudoparaphyses: 2 µm in diameter, branched, merging with the periphyses. Asci:  155–218 x 13–19 µm , 8–spored, cylindrical, short pedunculate, thick–walled, fissitunicate, without apical apparatus, arising in parallel from a basal ascogenous tissue. Ascospores:  37–55 x 7–11 µm, biseriate, fusiform, 1–septate, upon germination 3–septate, constricted at the central primary septum, hyaline, surrounded by an evanescent gelatinous sheath. Asexual morph: Undetermined.

Pertinent Literature:
NOTES: Kohlmeyer & Vittal (1986) ordinally referred this species to Lophiostoma, but was subsequently transferred to Astrosphaeriella by Hyde et al. (2000). A multigene study places this ascomycete in the Aigialaceae (Suetrong et al. 2009) and a new genus Rimora was introduced to accommodate it. It is a widely collected species as indicated by the number of countries listed above. It has been repeatedly collected in India mangroves (see references in Borse et al. 2012). Genus accepted as a marine species in Jones et al. (2015) and as a member of the Dothideomycetes by Hyde et al. (2013).
