The Echinodontiaceae are a family of crust fungi in the order Russulales. Species of this family, divided amongst two genera—Echinodontium and Laurilia—have a widespread distribution, although they are especially predominant in north temperate zones. They are parasitic or saprobic on wood, and may cause white rot of angiosperms and gymnosperms.
Species of this family have resupinate to - basidiocarps, smooth to spiny hymenophores, amyloid spores, dimitic hyphae, and cause white rot.
The family was circumscribed by Marinus Anton Donk in 1961, and monographed by Henry L. Gross in 1964. He recognized six species in the genus Echinodontium (E. tinctorium, E. tsugicola, E. ballouii, E. japonicum, E. taxodii and E. sulcatum) with hymenia ranging from smooth to spiny. Walter Jülich added another genus Laurilia (incorporating E. taxodii and E. sulcatum) when he described the family in 1981.Molecular phylogenetic studies show that the Echinodontiaceae belong in the Russuloid clade. Although some studies have suggested that the Echinodontium genus is closely related to Amylostereum, a more recent study does not support this conclusion.
