Additions to the taxonomy of <i>Phanerochaete</i> sensu lato (<i>Polyporales</i>, <i>Basidiomycota</i>); one new genus, two new species and twelve new combinations

<i>Corticium ochraceofulvum</i> and <i>Corticium subseriale</i>, two taxa with narrowly fusoid leptocystidia currently placed in <i>Phlebia</i>, are studied by morphology and nuclear rDNA sequences. Phylogenetic analyses show that the two species belong in <i>Phanerochaete</i>, despite having constantly clamped hyphae. Study of the type of <i>Xerocarpus cacao</i> shows that it is an older name for <i>Corticium subseriale</i>. The type of <i>Phanerochaete calotricha</i> is studied and material corresponding to the type sequenced. Specimens identified as <i>Phanerochaete calotricha</i> but differing genetically are described as <i>Phanerochaete volubilis</i>. <i>Phanerochaete avellanea</i> and <i>P. ericina</i> are confirmed as members of <i>Phanerochaete</i> based on nrDNA sequences and study of type material. Sequences from North America published as <i>Phanerochaete ericina</i> belong to a different species. <i>Odontia rufobrunnea</i> is identified as an earlier name for <i>Phanerochaete aculeata</i>. <i>Thelephora amphibolia</i> is identified as an earlier name for <i>Phanerochaete cumulodentata</i>. <i>Phanericium</i> is introduced for <i>Corticium tuberculatum</i> and related species, and a new species, <i>Phanericium gemellum</i>, is described. The new combinations <i>Phanericium americanum</i>, <i>P. rodriguezarmasiae</i>, <i>P. subglobisporum</i>, and <i>P. taiwanense </i>are proposed. <i>Corticium cremeoochraceum</i>, <i>Corticium jose-ferreirae</i>,and <i>Phanerochaete pallida</i> are confirmed as distinct species and transferred to <i>Phanerochaetella</i>. An ITS sequence of <i>Phanerochaetella jose-ferreirae</i> from the type locality is provided and the identity of <i>Corticium queletii</i> is discussed. Two ITS sequences of <i>Phanerochaetella exilis</i> from the vicinity of the type locality is presented. An earlier published sequence of <i>Phanerochaetella exilis</i> is considered to represent an unknown species
