MycoBank number: MB 552532; Index Fungorum number: IF 552532; Facesoffungi number: FoF 02665, 3 species.

Saprobic on dead and submerged wood in aquatic habitats. Sexual morph: Ascomata semi- immersed to erumpent, coriaceous, solitary, scattered, sometimes immersed under a pseudoclypeus, subglobose to ellipsoidal, black to brown, ostiolate. Peridium multi-layered, of black to brown cells of textura angularis, sometimes textura prismatica, somewhat carbonaceous, thin, easy to break. Hamathecium comprising few, long, broad, septate, branched, cellular pseudoparaphyses, surrounding asci and along the inner layer of the peridium. Asci 8-spored, bitunicate, fissitunicate, clavate, long-pedicellate, bulbous, thin-walled, with an apical ocular chamber. Ascospores 2- seriate, overlapping, ellipsoidal, narrowly subfusiform, conical at apex, hyaline, 1-septate, constricted at septum, guttulate, smooth-walled. Asexual morph: Hyphomycetous. Colonies black to dark-brown, circular, effuse. Mycelium composed of smooth, hyaline to dark brown, septate, branched, hyphae, swollen in ovoid cells (Phukhamsakda et al. 2016). Pseudoxylomyces elegans has holoblastic conidiogenesis, broadly fusiform, 4–7-septate, brown with paler end cell conidia (Tanaka et al. 2015).

Notes – Phukhamsakda et al. (2016) introduced Longipedicellataceae and included two genera, Longipedicellata and Pseudoxylomyces. Members of Longipedicellataceae were reported as saprobes on woody substrates in aquatic habitats (Phukhamsakda et al. 2016). Longipedicellataceae is characterized by semi-immersed or erumpent, clypeate ascomata on the host tissues, with black to brown ostioles, clavate asci with long pedicels, and 2-celled, hyaline ascospores. Chlamydospore formation is also a significant character of this family (Phukhamsakda et al. 2016).
