Taxonomy

''Datronia'' was circumscribed by Dutch mycologist

in 1966 to contain two species, the type, '' Datronia mollis'', and ''D. epilobii''. Donk explained that the genus description was abbreviated, as his intention was only to validly publish the genus, and that several contemporary authors had already accepted the name. ''Datronia'' is in the core polyporoid clade, a phylogenetic grouping of species first identified by Binder and colleagues in 2005. The clade contains many of the genera traditionally associated with the families
