Abstract

Alessioporus and Pulchroboletus are proposed as new monotypic genera to accommodate the thermo-xerophilic European species Xerocomus ichnusanus and X. roseoalbidus respectively. The present research focused on both morphological features and multigene molecular phylogeny (nrITS, nrLSU, tef-1 alpha datasets) to elucidate the taxonomic status of these two rare Mediterranean boletes and delineate a natural classification within the family Boletaceae. Macro- and microscopic descriptions of the two species based on inclusive taxon sampling are provided and supported by line drawings of the main anatomical features. Phylogenetic relationships, ecology, geographical distribution and delimitation from the most closely allied taxa also are highlighted. In addition, epitype specimens are selected for both species.
