Etymology: Named after its morphological similarity to Vaginatispora, but phylogenetically distinct. Saprobic on submerged decaying wood. Sexual morph Ascomata immersed to semi-immersed, erumpent, solitary, scattered, globose to subglobose, dark brown, coriaceous to carbonaceous, ostiolate. Papilla slit-like, variable in shape, central, crest-like at the apex, with irregular pore-like opening. Peridium composed of several layers of dark brown cells of textura angularis, merged with the host tissues. Hamathecium comprising numerous, filamentous, rarely branched and anastomosed, hyaline, pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, elongate ovoid to clavate, short pedicellate, knob-like or obtuse, slightly narrow, rounded at the apex. Ascospores 1–2-seriate, overlapping, broadly fusoid to fusiform, septate, slightly constricted at the septum, both cells at central septum wider, with a single large guttule towards the centre of each cell, surrounded by a prominent and thick-walled mucilaginous sheath with wavy edge, drawn out towards each end to forming tapering appendages. Asexual morph Undetermined.
Type species: Xenovaginatispora phichaiensis Boonmee, Huanraluek & K.D. Hyde.
