(mushroom beetles), a family of small beetles. The body is several centimeters long, oval, slightly convex, and covered with fine hairs. The color ranges from light brown to black, with light spots or bands usually on the wing cases. The female has four-jointed tarsi, and the male has three-jointed anterior tarsi. The larvae of Mycetophagidae are elongated and flat in the front, with rather large heads and short legs. The rear end of the body has a hook-shaped paranota that is bent upward. There are about 20 genera of Mycetophagidae, including 186 species; of these, 11 genera and 35 species are found in the USSR. The beetles live in fungi and rotten, moldy wood. They feed primarily on mycelia.
