Four new genera of the fungal family Boletaceae

Abstract

Based on our previous molecular phylogenetic analyses, four new genera are described, namely Baorangia, Lanmaoa, Parvixerocomus, and Rugiboletus, and one known genus, Neoboletus, is re-delimitated. Four new species and nine new combinations are proposed. Morphological characters of each genus and related eleven species are described and illustrated. Most of species in the genera described from southwestern China are wild edible mushrooms and can be found in free markets.
