Saprobic on dead plant stems or associated with leaves. Asexual morph: coelomycetous. Conidiomata acervular to pycnidioid, gregarious, immersed to semi-immersed, oval. Peridium of hyaline to pale brown, thick-walled cells forming textura angularis. Conidiophores arising from basal and lateral cells in cavity, cylindrical, septate, branched or rarely unbranched, sometimes reduced to conidiogenous cells, hyaline, smooth-walled. Conidiogenous cells subcylindrical, proliferating percurrently at apex, hyaline, smooth-walled. Conidia fusoid, straight, 2 or 3- septate, with 2–3(–4) tubular apical appendages; two median cells guttulate, fusoid, dark brown, thick-, smooth-walled; basal cell, narrowly obconic with a truncate base, hyaline, smooth-walled. Sexual morph: Undetermined (adapted from Crous et al. 2019a).

Notes: Pseudotruncatellaceae was introduced by Crous et al. (2019a) to accommodate a single genus Pseudotruncatella, which was previously placed in Amphisphaeriales genera incertae sedis (Perera et al. 2018).

Type genus: Pseudotruncatella R.H. Perera, Camporesi, Maharachch. & K.D. Hyde.
