<i>Phellinotus</i>, a neotropical genus of wood-decay fungi commonly found on living members of the Fabaceae family, was initially described as containing two species, <i>P</i>. <i>neoaridus</i> and <i>P</i>. <i>piptadeniae</i>. The members of this genus, along with six other well-established genera and some unresolved lineages, are the current representatives of the ‘phellinotus clade’. On the other hand, based on a two-loci phylogenetic analysis, some entities/lineages of the ‘phellinotus clade’ have been found in <i>Fomitiporella</i> s.l. In this work, we performed four-loci phylogenetic analyses and based on our results the genera of the ‘phellinotus clade’ are shown to be monophyletic groups. In addition to the natural groups confirmed as different genera, morphological revisions, phylogenetic relationships, and host distribution of different specimens resembling <i>P</i>. <i>neoaridus</i> and <i>P</i>. <i>piptadeniae</i> revealed three new species in the <i>Phellinotus</i> genus, referred to here as <i>P</i>. <i>magnoporatus</i>, <i>P</i>. <i>teixeirae</i> and <i>P</i>. <i>xerophyticus</i>. Furthermore, for <i>P</i>. <i>piptadeniae</i> a narrower species concept was adopted with redefined morphological characters and a more limited distribution range. Both <i>P</i>. <i>neoaridus</i> and <i>P</i>. <i>teixeirae</i> have a distribution range restricted to seasonally dry tropical forests in South America. Additionally, based on detailed morphological revisions <i>Phellinus</i> <i>badius</i>, <i>Phellinus</i> <i>resinaceus</i>, and <i>Phellinus</i> <i>scaber</i> are transferred to the <i>Phellinotus</i> genus. The geographic distribution and host range of the genus are then discussed.
