ABSTRACT=<p>The phylogenetic analyses of the family Irpicaceae were carried out based on a complete global sampling. The dataset that included concatenated ITS1-5.8S-ITS2 and nrLSU sequences of 67 taxa of Irpicaceae from around the world was subjected to the maximum likelihood analyses and Bayesian inference. In the phylogenetic tree, species from 14 genera were distributed in nine clades, among which five genera—<italic>Irpex, Phanerochaetella, Byssomerulius, Cytidiella</italic>, and <italic>Meruliopsis</italic>, received high support values. The genus <italic>Efibula</italic> was shown to be paraphyletic and four subclades could be recognized, while <italic>Phanerochaete allantospora, Leptoporus mollis</italic>, and several species from <italic>Ceriporia</italic> and <italic>Candelabrochaete</italic> formed a large clade with relatively strong support. Based on the molecular and morphological evidence, seven new corticioid species<bold>—</bold><italic>Candelabrochaete guangdongensis, Efibula grandinosa, E. hainanensis, E. shenghuae, E. taiwanensis, Irpex alboflavescens</italic>, and <italic>Phanerochaetella sinensis</italic>, were revealed from the materials mostly from East Asia. The monotypic genus <italic>Flavodontia</italic>, newly described from southwestern China, is regarded as a later synonym of <italic>Irpex</italic>, and the new combination <italic>I. rosea</italic> is proposed. In addition, <italic>Phanerochaetella queletii</italic> is proposed for a taxon first described from Italy and newly recorded from China; <italic>Phanerochaete jose-ferreirae</italic> from Portugal is determined to be a later synonym. Descriptions and illustrations of the new species and the newly combined taxa are presented, and morphological comparisons for the known species of <italic>Efibula</italic> and <italic>Phanerochaetella</italic> are provided.</p>
