Anisotoma is a genus of small beetles in the family Leiodidae, commonly known as slime mold beetles or round fungus beetles. The genus contains at least 20 described species, with six monophyletic species groups comprising 35 known species including 13 described in a 1979 revision. These beetles are specialized associates of slime molds (Myxomycetes). The genus originated in North America from a Holarctic common ancestor shared with the related genus Agathidium, subsequently dispersing to Palearctic and Central American regions.
