本文对多孔菌属‘Favolus群’及其近缘种进行了分类研究。对NurLSU及其区域的系统发育分析表明，亚属‘Favolus群’分为两个主要分支。该群内的真菌共享侧向具柄的担子果，具有非硬壳的柄表面，并可通过菌盖表面的形态来区分。一个分支的特征是皮肤透明到棕色，由透明到棕色凝集的生殖菌丝组成。另一个分支的菌毛呈放射状条纹，缺乏明显的菌丝凝集层。我们提出了Neofavolus gen.Nov.，以N.alveolaris为代表，用于前者的分支，并为后者的分支修订了Favolus属，以F.brasilisis为代表。Neofavolus包括N.mikwai和N.cremeoalbidus sp.Nov.，除N.alveolaris外，仅从温带的东亚已知。Favolus包括多孔菌复合体、细多孔菌复合体和拟贝氏多孔菌复合体的成员。我们发现，在亚洲被称为‘P.gram cephalus’的多孔菌包括F.acervatus和F.merici(=P.gram mocephalus)，而‘P.tenuillus’包括三个不同的种：来自热带美洲的F.brasiliensis和来自热带亚洲的F.spathulatus和F.roseus。对Favolus和Neofavolus中被接受的物种提供了详细的描述和插图。
We present a taxonomic study of 'group Favolus' and related species in Polyporus. Phylogenetic analyses of nurLSU and ITS regions revealed that the infrageneric 'group Favolus' is divided into two main clades. Fungi within the group share laterally stipitate basidiocarps, with non-crustose stipe surfaces, and are distinguishable by the morphology of the pileus surface. One clade is characterized by species with hyaline to brown cutis, composed of hyaline to brown agglutinated generative hyphae. The other clade accommodates species with radially striate pileus, and lacks any distinct cutis of agglutinated hyphae. We propose Neofavolus gen. nov., typified by N. alveolaris, for the former clade, and revise the genus Favolus, typified by F. brasiliensis, for the latter clade. Neofavolus includes N. mikawai and N. cremeoalbidus sp. nov., known only from temperate eastern Asia, in addition to N. alveolaris. Favolus includes members of the Polyporus grammocephalus complex, the P. tenuiculus complex, and P. pseudobetulinus. We reveal that the polypore known as 'P. grammocephalus' in Asia includes F. acervatus and F. emerici (= P. grammocephalus), whereas 'P. tenuiculus' includes three distinct species; F. brasiliensis from tropical America, and F. spathulatus and F. roseus from tropical Asia. Detailed descriptions and illustrations are provided for the accepted species in Favolus and Neofavolus.
