abstract = {Phylogenetic relationships were investigated among North American species of <i>Laetiporus, Leptoporus, Phaeolus, Pycnoporellus</i> and <i>Wolfiporia</i> using ITS, nuclear large subunit and mitochondrial small subunit rDNA sequences. Members of these genera have poroid hymenophores, simple septate hyphae and cause brown rots in a variety of substrates. Analyses indicate that <i>Laetiporus</i> and <i>Wolfiporia</i> are not monophyletic. All North American <i>Laetiporus</i> species formed a well-supported monophyletic group (the core <i>Laetiporus</i> clade or <i>Laetiporus</i> s.s.) with the exception of <i>L. persicinus</i>, which showed little affinity for any genus for which sequence data are available. Based on data from GenBank, the southern hemisphere species <i>L. portentosus</i> also fell well outside the core <i>Laetiporus</i> clade. <i>Wolfiporia dilatohypha</i> was found to represent a sister group to the core <i>Laetiporus</i> clade. Isolates of <i>Phaeolus, Pycnoporellus</i> and members of the core <i>Laetiporus</i> clade all fell within the Antrodia clade of polypores, while <i>Leptoporus mollis</i> and <i>Laetiporus portentosus</i> fell within the phlebioid clade of polypores. <i>Wolfiporia cocos</i> isolates also fell in the Antrodia clade, in contrast to previous studies that placed <i>W. cocos</i> in the core polyporoid clade. ITS analyses resolved eight clades within <i>Laetiporus</i> s.s., three of which may represent undescribed species. A combined analysis using the three DNA regions resolved five major clades within <i>Laetiporus</i> s.s.: a clade containing conifer-inhabiting species (Conifericola clade), a clade containing <i>L. cincinnatus</i> (Cincinnatus clade), a clade containing <i>L. sulphureus</i> s.s. isolates with yellow pores (Sulphureus clade I), a clade containing <i>L. sulphureus</i> s.s. isolates with white pores (Sulphureus clade II) and a clade containing <i>L. gilbertsonii</i> and unidentified isolates from the Caribbean (Gilbertsonii clade). Although there is strong support for groups within the core <i>Laetiporus</i> clade, relationships among these groups remain poorly resolved.}
