Global diversity of the <i>Tylopilus alboater</i> complex (<i>Boletaceae</i>, <i>Boletales</i>): new genus and species, and typification of the name <i>Boletus alboater</i>.

ABSTRACT: Recognition of Tylopilus alboater once relied heavily on the morphological features of the basidiomata, which resulted in considerable confusion due to morphological stasis and plasticity. In this study, we examined specimens morphologically identified as T. alboater from Asia, North America, and Australia using phylogenomics and multi-locus sequence data. To clarify its phylogenetic placement within Boletaceae, we conducted a phylogenomic analysis based on 45 genomes (including three newly sequenced T. alboater genomes) comprising representatives from the eight subfamilies of Boletaceae. Additionally, we constructed a concatenated dataset (nrLSU + tef1-α + rpb1 + rpb2), incorporating representative species from all genera within the
