The phlebioid clade (Polyporales, Basidiomycota) accommodates numerous species of corticioid and polyporoid fungi of the Phanerochaetaceae, Irpicaceae, and Meruliaceae. The present study used morphological and phylogenetic approaches to revise the generic classification of the phlebioid clade and survey species diversity. The phylogenetic analyses were performed using sequences of multiple genes, including the nuc rDNA ITS1-5.8S-ITS2 (ITS), the D1-D2 domains of 28S rDNA (28S), the RNA polymerase II largest subunit (rpb1), the RNA polymerase II second largest subunit (rpb2), and the translation elongation factor 1-α (tef1). We overall recognize 57 genera including six new ones (Alboefibula, Cremeoderma, Gelatinofungus, Luteochaete, Phanerochaetella and Quasiphlebia). We describe 26 new species belonging to 15 genera (Alboefibula bambusicola, A. gracilis, Crustodontia taiwanensis, Cytidiella albomarginata, Efibula matsuensis, E. turgida, E. subglobispora, Gelatinofungus brunneus, Hydnophlebia aurantia, H. crocata, Irpex lenis, Mycoaciella efibulata, Phanerochaete alpina, P. crystallina, P. guangdongensis, P. rhizomorpha, P. spadicea, P. subcarnosa, Phanerochaetella formosana, Phlebiopsis odontoidea, P. yushaniae, Quasiphlebia densa, Rhizochaete chinensis, Roseograndinia jilinensis, R. minispora, and Scopuloides allantoidea), and present 18 new combinations belonging to 12 genera (Cremeoderma unicum, Crustodontia nigrodontea, C. tongxiniana, Cytidiella albida, Efibula intertexta, Hydnophlebia alachuana, Irpex laceratus, I. latemarginatus, I. rosettiformis, Luteochaete subglobosa, Luteoporia lutea, Phanerochaetella angustocystidiata, P. exilis, P. leptoderma, P. xerophila, Phlebiopsis alba, Rhizochaete lutea, Scopuloides dimorpha). Descriptions, illustrations and notes of new species and some new records are provided, as well as identification keys to genera of each family.

phlebioid 进化枝 (Polyporales, Basidiomycota) 容纳了 Phanerochaetaceae、Irpicaceae 和 Meruliaceae 的多种皮质类和多孔类真菌。本研究使用形态学和系统发育方法来修改 phlebioid 进化枝的一般分类和调查物种多样性。使用多个基因的序列进行系统发育分析，包括 nuc rDNA ITS1-5.8S-ITS2 (ITS)、28S rDNA (28S) 的 D1-D2 结构域、RNA 聚合酶 II 最大亚基 ( rpb1 )、RNA 聚合酶II 第二大亚基 ( rpb2 )，以及翻译延伸因子 1-α ( tef1 )。我们总共识别了 57 个属，包括 6 个新属（Alboefibula、Cremeoderma、Gelatinofungus，Luteochaete，Phanerochaetella和Quasiphlebia）。我们描述了26种新属15属（Alboefibula竹黄，A.纤细，Crustodontia黄山松，Cytidiella albomarginata，Efibula matsuensis，E. turgida，E. subglobispora，Gelatinofungus蠹，Hydnophlebia aurantia，H. crocata，白耙齿lenis，Mycoaciella efibulata，白腐霉，P. crystallina，P. guangdongensis，P. rhizomorpha，P. spadicea，P. subcarnosa，Phanerochaetella枫香，Phlebiopsis odontoidea，P. yushaniae，Quasiphlebia致密，Rhizochaete羊草，Roseograndinia jilinensis，R. minispora和Scopuloides allantoidea），和本18个属于新组合到 12 个属（Cremeoderma unicum , Crustodontia nigrodontea , C. tongxiniana , Cytidiella albida , Efibula intertexta ,Hydnophlebia alachuana，耙菌属laceratus，I. latemarginatus，I. rosettiformis，Luteochaete subglobosa的，Luteoporia球菌，Phanerochaetella angustocystidiata，P.蕨，P. leptoderma，P. xerophila，Phlebiopsis粉，Rhizochaete球菌，Scopuloides dimorpha）。提供了新种和一些新记录的描述、插图和注释，以及每个科属的识别码。
