Abstrakt: Species of Gyroporus from southern China were studied in this study. Based on morphology and molecular phylogenetic analyses of DNA sequences from the nuclear ribosomal internal transcribed spacer (ITS), the nuclear ribosomal large subunit (nrLSU), and the mitochondrial adenosine triphosphate ATP synthase subunit 6 ( atp6), Gyroporus was divided into four main branches in the phylogenetic tree, and four sections were firstly proposed i.e. Gyroporus sect. Castaneus, G . sect. Cyanescens, G . sect. Longicystidiatus and G . sect. Pallidus . Five new species, i.e. G. alboluteus, G. atrocyanescens, G. pseudolongicystidiatus, G. pallidus and G. subcaerulescens , were revealed from China, and their phylogenetic positions were also analysed. Among them, G. alboluteus and G. pallidus were nested into the sect. Pallidus , although morphologically similar to G. castaneus; G. atrocyanescens and G. subcaerulescens , with obvious cyanescent oxidation reactions, were nested into the sect. Cyanescens ; and G. pseudolongicystidiatus characterised by its long cystidia and was nested into the sect. Longicystidiatus . The new species were formally described and illustrated in the present study, and a key to the sections and species of Gyroporus in China was provided.
