The Ganodermataceae are a family of wood-decaying polypores characterised by their thick, tough to woody basidiocarps, often forming large brackets or sessile to stipitate conks on living or dead trees. Fruitbodies typically have a laccate (varnished) or dull, zonate surface, with colours ranging from yellow‑brown and red-brown to dark chestnut. The pore surface is usually white to cream, bruising brown in many species.
