Acrospermales was introduced by Minter (2007) to accommodate Acrospermaceae. The ordinal position of Acrospermaceae was previously unresolved and was referred to various orders by many authors. First, it was placed in Hysteriales or Dothideales in the 1st and 2nd editions of Ainsworth & Bisby’s Dictionary of the Fungi (Kirk et al. 2001). In the 3rd to 5th editions it was transferred to the Dothideales and in the 6th and 7th it was placed in the Ostropales and Clavicipitales, respectively. The family was also placed, rather hesitantly, in Pyrenulales by Eriksson (1982). Barr (1990) argued its ordinal position in more detail, and transferred it to Xylariales. Minter et al. (2007) introduced a new species in Acrospermaceae and discussed the ordinal position of Acrospermaceae with the introduction of Acrospermales. The divergence time for Acrospermales is estimated as 156 MYA (stem age, Hongsanan et al. 2020) (Fig. 3).

Accepted families: Acrospermaceae.
