Systematics
The family is classified as incertae sedis with respect to ordinal placement in the Lecanoromycetidae, as there is no reliable molecular data available to establish phylogenetic relationships with similar taxa.Genus Biatorella was circumscribed by Italian botanist Giuseppe [De Notaris] in 1846, with Biatorella rousselii assigned as the type species. The family Biatorellaceae was originally proposed by French lichenologist Maurice Choisy in 1949, but he did not publish the name validly. Josef Hafellner and Manuel Casares published the name validly in 1992.
