Perera et al. (2018) introduced Pseudotruncatella in Amphisphaeriales genera incertae sedis based on analysis of combined LSU, ITS, and SSU sequence data. Three species have been reported. Pseudotruncatella bolusanthi Crous was introduced from the living leaves of Bolusanthus speciosus in South Africa, and the family Pseudotruncatellaceae was introduced to accommodate Pseudotruncatella in Amphisphaeriales (Crous et al. 2019). Pseudotruncatella bolusanthi can be distinguished from P. arezzoensis based on its smaller, 2-septate conidia (17–20 × 6.5–7 μm vs 20–25 × 5.4–6.5 μm, 3-septate in P. arezzoensis). Pseudotruncatella camporesii Goonas. & Hyde was introduced from a dead stem of Helichrysum sp. in Italy (Hyde et al. 2020) and it can be distinguished from P. arezzoensis by its conidiomata (170–250 μm high, 280–400 μm wide vs 230–275 μm high, 255–280 μm wide in P. arezzoensis). Pseudotruncatella arezzoensis was isolated from dead branches of Cytisus and Helichrysum species from Italy (Perera et al. 2018). Pseudotruncatella arezzoensis has pycnidioid, immersed to semi-immersed conidiomata, while in P. camporesii they are acervular to pycnidioid, semi-immersed to superficial (Hyde et al., 2020).
