Notes: Odontia was introduced by Persoon (1794) with the type species O. ferruginea Pers. Odontia had been considered to be a synonym of Tomentella. However, recent phylogenetic analyses revealed that Odontia was in a monophyletic position close to Tomentella, and the species were generally collected in old forests possessing a saprotrophic lifestyle compared with an ectomycorrhizal one (Gorjó nand Greslebin 2012; Tedersoo et al. 2014). The general characteristics of the genus are: resupinate and arachnoid basidiomata which are separable from the substrate, smooth to granulose or hydnoid hymenophoral surface, a dimitic hyphal system in the rhizomorphs, a monomitic or dimitic hyphal system in the subiculum, clavate basidia and irregular ellipsoid to globose verruculose basidiospores (Kõljalg 1996; Yuan et al. 2018). The species of Odontia were reported to be spread over temperate Eurasia, North America, Africa, France, Australia, New Zealand, China and Turkey (Rodway 1897; Larsen 1974; Kõljalg 1996; Kõljalg and Larsson 1998; Gorjó nand Greslebin 2012; Tedersoo et al. 2014; Yuan et al. 2018).

Type species: Odontia ferruginea Pers., Neues Mag. Bot. 1: 110 (1794).

Other accepted species: Species Fungorum – search Odontia.
