approach coupled with a technique known as "temporal banding", Kraichak and colleagues proposed to fold the family Miltideaceae into the Agyriaceae. 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.
