The Mycetophagidae or hairy fungus beetles are a family of beetles in the superfamily Tenebrionoidea. The different species are between 1.0 and 6.5 mm in length. The larvae and adults live in decaying leaf litter, fungi, and under bark. Most species feed on fungi (hence the name). Worldwide, the 18 genera contain around 200 species.
