| 摘要 | The broad generic concept of Phanerochaete is one of the largest genera in corticoid fungi, decomposing various woody substrata and causing a white rot. Two new genera of Phanerochaete s.l. are presented, namely Hydnophanerochaete and Odontoefibula. The generic type of Hydnophanerochaete is Phanerochaete odontoidea. Odontoefibula is established based on a new species, O. orientalis (generic type), and O. deflectens (≡ Grandinia deflectens). Both genera are characterized by having an effused basidiocarp with odontioid hymenial surface, simple-septate generative hyphae, cystidia lacking, clavate basidia, ellipsoid basidiospores which are smooth, thin-walled, inamyloid, non-dextrinoid, and acyanophilous. Hydnophanerochaete is diagnostic by its compact texture of subiculum with thick-walled subicular hyphae, and presence of quasibinding hyphae. Odontoefibula is featured by its basidiocarp turning dark brown in KOH, and dense texture of subiculum with thin- to slightly thick-walled subicular hyphae. Morphological study and multigene phylogenetic analyses based on sequences inferred from two combined datasets (nrITS+nrLSU+rpb1 and nrITS+nrLSU) respectively, indicate that Hydnophanerochaete and Odontoefibula are respectively placed in Meruliaceae and Donkia clade of Phanerochaetaceae. Phanerochaete subodontoidea is a synonym of P. odontoidea, according to morphological and molecular evidence. |
