Among Boletales, the family Boletaceae has the highest diversity worldwide. Additionally, this fungal group has great ecological relevance because it not only includes mainly ectomycorrhizal but also saprotrophic species. Furthermore, some species are used as food and have sociocultural and economic importance worldwide. In Mexico, the Boletaceae family boasts a substantial number of species, yet our understanding of these species remains far from comprehensive. In this work, by using macro- and micromorphological and phylogenetic analyses of DNA sequences from multi-gene analyses based on ITS, nrLSU, rpb1, rpb2, and tef1, we report five new species belonging to the genera Aureoboletus and Chalciporus: A. ayuukii and A. elvirae from a Quercus scytophylla forest, A. readii from a mixed forest, C. perezsilvae from cloud forest, and C. piedracanteadensis from both a mixed coniferous forest and a Quercus-Pinus forest. In Mexico, four species of Aureoboletus are used as a food source, and in this work, we add another one, A. readii, which is traditionally consumed by members of the Tlahuica-Pjiekakjoo culture, who are located in the central part of the country. This work contributes to our knowledge of two genera of Boletaceae in a geographical area that is scarcely studied, and thus, our understanding of its biocultural relevance is enriched.
