Saprobic on intertidal wood of Aegiceras corniculatum. Sexual morph: Ascomata 200–400 μm high, 100–400 μm diam. (= 300 × 356 μm, n = 25) immersed to partially erumpent, sub globose to conical, solitary to gregarious, coriaceous to carbonaceous, black, ostiolate. Ostiole 60–200 μm long, 50–200 μm diam. (= 126 × 99 μm, n = 20), black, medium to long slit like, crest shaped on the host surface, papillate, filled with brown cells. Periphyses 20–40 μm long 1.3–3.9 μm wide, (= 25.1–2.5 μm, n = 20) wide, unbranched facing upwards. Peridium unequal in thickness 15–40 μm (= 24.4 μm, n = 20) wide at the base and 20–70 μm (x = 37.1 μm, n = 20) wide at sides, comprising two layers, inner strata with several layers of hyaline to light brown cells of textura angularis and outer strata with compact light brown to brown pseudoparenchymatous cells fusing with the host tissue. Hamathecium composed of 1–4 μm (= 2.7 μm, n = 20) wide, numerous, septate, unbranched, cellular pseudoparaphyses resembling hyphae embedded in a gelatinous matrix, anastomosing above the asci, fused at the base and sides of the ascomata and united at the apex with the periphyses. Asci 75–190 × 8–25 μm (x = 135 × 14 μm, n = 40), 8-spored, bitunicate, fissitunicate, cylindrical to clavate, with medium to long pedicel, 10–90 μm (= 36.6 μm, n = 40), apically rounded, sub apically thickened with an ocular chamber. Ascospores 22–30 × 4–8.7 μm (x = 25.2 × 6.8 μm, n = 50) uniseriate to biseriately arranged, partially overlapping, constricted at the septa, smooth-walled, hyaline, fusiform to ellipsoidal, 1–2-guttulate, each cell contains a large guttule closer to the central septum, with or without an indistinct mucilaginous sheath, with distinct, partly curved, hyaline, polar appendages 2–8 μm (= 5.5 μm, n = 35) long and 1–3 μm (= 2.6 μm, n = 35) wide at both ends. Asexual morph: Undetermined
