Agyrium Miltidea The Agyriaceae are a family of lichenized fungi in the order Pertusariales.

[1] The family was circumscribed by August Carl Joseph Corda in 1838.

[2] In 2018, using a molecular phylogenetic approach coupled with a technique known as "temporal banding", Kraichak and colleagues proposed to fold the family Miltideaceae into the Agyriaceae.

[3] A close genetic relationship between these two families had previously been noted.

The proposal to subsume Miltideaceae into the Agyriaceae was accepted in a later critical analysis of the temporal banding technique for fungal classification.
