and in Barrmaeliaceae (fam. nov., Xylariales) and critical notes on -like genera based on multigene phylogenies.

Phylogenetic analyses of a combined DNA data matrix containing ITS, LSU, and sequences of representative Xylariales revealed that the genus is a well-defined monophylum, as based on four of its described species (, , , ) and the new species . The generic type of , , is revealed as the closest relative of , being phylogenetically distant from the generic type of , , which belongs to Xylariaceae sensu stricto. and are highly supported and form a distinct lineage, which is recognised as the new family Barrmaeliaceae. The new species is described. , and are epitypified and is lecto- and epitypified. Published sequences of and several -like species from the genera , , , and are evaluated, demonstrating the necessity of critical inspection of published sequence data before inclusion in phylogenies. Verified isolates of several species from these genera should be re-sequenced to affirm their phylogenetic affinities. In addition, the generic type of should be sequenced before additional generic re-arrangements are proposed.
