Tritoma is a genus of beetles in the family Erotylidae, the pleasing fungus beetles. It is distributed worldwide, mainly in the Old World.[2] There are over 100 species.[2]

Some species consume euagaric mushrooms, staying concealed amidst the gills as they feed.[3] Some feed on mushrooms growing from dead trees, as well as mycorrhizae on living roots.[4] One of the most common pleasing fungus beetles in Europe, T. bipustulata, is a black beetle with red spots which engages in autohaemorrhaging as a defensive behavior.[5]

Molecular analysis suggests that Tritoma is paraphyletic, and might be best treated as two separate genera.[3]
