Tooth fungi are a relatively small group of fungi whose mushroom bears its spores on a hymenium - a layer of "mother cells" - that grow on the outside of tooth-like spines. These spines can either grow in branches from the side of the host (as in Hericium coralloides) or on the underside of the cap (as in the Hedgehog fungus, Hydnum repandum). Most tooth fungi are hard and inedible. However, a few (such as the bearded tooth Heracium erinaceum) are not. These are often prized as easily identifiable edibles.

Tooth fungi are a relatively small polyphyletic group of fungi whose mushroom bears its spores on a hymenium - a layer of "mother cells" - that grow on the outside of tooth-like spines, or "teeth".
Although many tooth fungi are hard and inedible, some are prized both for their flavor and their ease of identification, such as Hericium erinaceus, the "bearded toothmushroom".
Another fungus - the toothed jelly fungus, Pseudohydnum gelatinosum - has "teeth" but is an even more distantly related, as one of the jelly fungi.
