This is a list of fungal genera in the order Agaricales. The list follows Kalichman, Kirk & Matheny (2020),[1] with more recent additions and amendments, as noted. The number of species in each family is taken from Catalogue of Life (2023)[2] and is subject to change as new research is published. Many genera are not as yet assigned to a family and are listed under "incertae sedis".
