The Bankeraceae are a distinctive family of tooth fungi recognised by their spore-bearing spines on the underside of the cap. Unlike gilled or pored mushrooms, members of this family produce a dense layer of downward-pointing teeth, usually pale when young and darkening as they mature. Fruitbodies are typically stout, leathery, or corky, often with zoned, velvety, or scaly caps, and many species show dramatic colour changes as they age or dry. All known species are mycorrhizal, forming symbiotic associations with forest trees, and are therefore found on soil, never on wood..
