Hamathecium comprising persistent narrow cellular pseudoparaphyses, septate, wide, hyaline, branched with darkened apices, in a gel matrix. Asci 8-spored, fissitunicate, clavate to cylindrical. Ascospores overlapping 2-seriate, hyaline, lightly pigmented to dark brown, 2-celled to muriform. Asexual morph: psiloglonium stygiumlike (Boehm et al. 2009a, Jayasiri et al. 2017a).

Notes – Boehm et al. (2009b) elevated the genus to family rank and Boehm et al. (2009a) justified reinstating Gloniaceae and, more importantly, recognising it at family rank for a single genus, because of the high support the group received in a four-gene phylogenetic analysis. The family comprises two other genera, Cenococcum and Purpurepithecium (Spatafora et al. 2012, Jayasiri et al. 2017a).
