Alexiidae is a family of beetles. It contains a single genus, Sphaerosoma, formerly included within the family Cerylonidae, with around 50 species which are native to the western Palearctic. Species of Sphaerosoma are very small, around 1 to 2 mm in length rounded beetles with clubbed antennae. They are fungivores, having been observed feeding on mushrooms, and have also been found in leaf litter and on decaying bark.
