The Endomychidae are a group of often brightly coloured fungus-feeding beetles.

Frontoclypeal suture present; antennae moderately long, usually with relatively loose club; maxillary palps fusiform, labial palps may be securiform; fore coxae globular, trochantins concealed, fore coxal cavities externally open or closed, internally closed; mid coxal cavities moderately to widely separated, laterally open or closed; tarsi trimerous or tetramerous, second tarsal segment commonly lobed, extending beneath reduced third segment; tarsal claws simple; abdomen with five or six ventrites, none connate, femoral lines on first ventrite usually absent. Larva usually oblong to ovate (rarely elongate), slightly to strongly flattened, usually with lateral tergal processes on all thoracic and most abdominal segments and only rarely with short urogomphi; antennae often long (with segment 2 elongate and 1 and 3 reduced), their sockets well separated from mandibular articulations; head often broad at base, strongly narrowed towards mouth-parts; mala obtuse.
