The phylogeny of the poroid and hydnoid genera Antrodiella, Junghuhnia, and Steccherinum (Polyporales, Basidiomycota) was studied utilizing sequences of the gene regions ITS, nLSU, mtSSU, atp6, rpb2, and tef1. Altogether 148 taxa, represented by 549 sequences, were included in analyses. Results show that most species of these genera form a well supported clade in the Polyporales, called Steccherinaceae, along with 12 other hydnoid and poroid genera. Within the Steccherinaceae, generic concepts need to be revised: no fewer than 15 new genera are needed to accommodate existing and new species. At least 16 transitions have taken place between poroid and hydnoid hymenophore types within the Steccherinaceae, and similar plasticity can be seen in microscopic characters. Nevertheless, natural genera revealed in the analysis can mostly be characterized morphologically and, with few exceptions, poroid and hydnoid species belong to separate genera. The genus Steccherinum is shown to contain both hydnoid and poroid species. Species of the former Antrodiella belong to at least 10 genera within the Steccherinaceae.
