studies showed that Agyriineae was not related to the Lecanorales, and the order Agyriales was resurrected to contain the family. Some authorities considered Trapeliaceae to be synonymous with Agyriaceae. In 2007, Thorsten Lumbsch and colleagues transferred Trapeliaceae to the order Baeomycetales based on a

relationship between Trapeliaceae and a clade in the Baeomycetales. This placement contradicted the results of some previous phylogenetic analyses that showed the Trapeliaceae as neither sister nor contained within the Baeomycetales. In 2011, Brendan Hodkinson and James Lendemer proposed the order Trapeliales to contain the family, as they considered the family to be part of "a clade that is molecularly and morphologically distinct from Baeomycetales". In 2018, the

In a later review of the use of this method for biological classification, Robert Lücking considered this merge justified. This synonymy has been accepted in a recent review of fungal classification.
