Description
Saprobic on immersed rachis of Nypa fruticans. Sexual morph: Ascomata in vertical section 250–340 μm high, 215–385 μm diam. (x̅ = 310 × 326 µm, n = 10), dark brown to black, scattered, semi-immersed, erumpent, subglobose to elongated, base flatted, coriaceous to carbonaceous. Ostiole crest-like, variable in shape, central papillate. Peridium 15–38 µm wide, wider at the apex and thinner at the base, composed of several pale brown to brown cells of textura angularis, cells towards the inside lighter, at the outside darker, somewhat flattened, fusing and with the host tissues. Pseudoparaphyses 1–2.5 µm wide, hypha-like, numerous, septate, rarely branched and anastomosed, tapering towards the apex. Asci 89–115 × 12–20 µm (x̅ = 100.5 × 16.0 µm, n = 20), 8-spored, bitunicate, fissitunicate, cylindric-clavate, with a short bulbous pedicel, rounded at the apex, with an ocular chamber. Ascospores 23–45 × 6–9 µm, (x̅ = 35.3 × 7.5 µm, n = 30), hyaline or rarely pale brown, uniseriate or overlapping to biseriate, 1-septate, occasionally producing pseudosepta, slightly constricted at the central septum, cell above central septum swollen, guttulate, smooth-walled, surrounded by a narrow mucilaginous sheath and drawn out towards each end to form tapering appendages, 6–8 µm long. Asexual morph: Undetermined.
Culture conditions: Colonies growing on PDA reaching 2 cm diam. after 21 days at 25°C.
