摘要

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