MycoBank number: MB 317136; Index Fungorum number: IF 317136, Facesoffungi number: FoF 06123; Fig. 37
Saprobic on frond bases of Nypa fruticans. Sexual morph: Ascomata 425–866 µm height, 115–310 µm in diam around the center, obtusely clavate to fusiform, pedicellate, solitary or aggregated, superficial, ostiolate, coriaceous, olive-brown. Ascoma attached by a hypostroma immersed in the host tissue of N. fruticans. Hamathecium comprising 1.25–2.5 µm in diam., simple, numerous, septate trabeculate, hyaline, pseudoparaphyses. Asci 300–605 × 30–42.5 µm, 8-spored, cylindrical, bitunicate, thick-walled, with an apical apparatus. Ascospores 95–112.5 × 20–30 µm, uni-seriate, fusiform, apiculate, light brown to dark brown, unequally 1-septate, constricted at the septum, apical cell larger, basal cell, turbinate, light brown, with a gelatinous appendage at the spore apex. Asexual morph: Undetermined.
Material examined: Thailand, Suratthani Province, Ban Hui Sap Mangrove Forest, superficial on frond bases of Nypa fruticans, 8 Jan 2019, S. Preedanon & S. Suetrong (BBH 45364).
Notes: The genus has been reported as a saprobe from bark of dead roots, and from a seedling of Rhizophora mangle in Guatemala (see morphology Suetrong et al. 2010).
