The phylogenetic status of several taxonomically important wood-decaying species belonging to Phellinus s. l. and Inonotus s. l. was investigated by analyzing sequence data from ribosomal DNA ITS regions of 26 species. As expected, an evaluation of the results confi rmed Phellinus s. l. and Inonotus s. l. as being polyphyletic. Th e generic concept of Inonotus s. str. was revised from a molecular and morphological point of view. Further analyses are still needed for a more comprehensive delimitation between Phellinus s. l. and Inonotus s. l. A comparison of results found in several publications might elucidate the phylogenetic identity of taxonomically problematic taxa belonging to these groups. Two new combinations in the genus Xanthoporia Murrill were made.
