Notes – Perera et al. (2018) established the asexual morphic genus Pseudotruncatella to accommodate P. arezzoensis. Pseudotruncatella bolusanthi was added to the genus, and the family Pseudotruncatellaceae was introduced to accommodate them (Crous et al. 2019a). The genus is characterized by acervular to pycnidioid conidiomata, holoblastic, annellidic, conidiogenous cells, 2 or 3-septate, fusiform to clavate conidia with up to 2–3(–4) apical appendages and dark brown median cells (Perera et al. 2018, Crous et al. 2019a).
