Phylogenetic relationships were investigated among North American species of Laetiporus, Leptoporus, Phaeolus, Pycnoporellus, and Wolfiporia 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 Laetiporus and Wolfiporia are not monophyletic. All North American Laetiporus species formed a well supported monophyletic group (the "core Laetiporus clade" or Laetiporus s.s.) with the exception of L. persicinus, which showed little affinity for any genus for which sequence data are available.
