The family was named by
Theodor Magnus Fries
Theodor "Thore" Magnus Fries (28 October 1832 – 29 March 1913), was a Swedish botanist, lichenologist, and Arctic explorer. He was the son of the mycologist Elias Fries.
Following in his father's footsteps, Fries studied botany, obtaining his ...

Arctomia'' as the

In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name.

Classification
The
order Arctomiales was proposed by Soili Stenroos, Jolanta Miadlikowska, and François Lutzoni in 2014 to contain this family.
In 2018, the class
Lecanoromycetes
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence.

This synonymy was also accepted in later compilations of fungal classification, and Arctomiaceae is
classified in the order Baeomycetales.
