Abstract
ABSTRACTSpecies of Pulveroboletus (Boletaceae, Boletales) in China are investigated on the basis of morphology and molecular phylogenetic analyses of DNA sequences from nuc rDNA region encompassing the internal transcribed spacers 1 and 2, along with the 5.8S rDNA (ITS) and nuc 28S rDNA D1–D2 domains (28S) and sequences from the translation elongation factor 1-α gene (TEF1). Nine species are recognized in the country, three of them are described as new: P. flaviscabrosus, P. rubroscabrosus, and P. subrufus, five of them are previous described taxa: P. brunneopunctatus, P. brunneoscabrosus, P. macrosporus, P. reticulopileus, and P. sinensis, the remaining one is tentatively named P. cf. ridleyi, which will be further studied in the future. A key to the Chinese taxa of the genus is provided. Unexpectedly, the current study did not identify disjunct populations of Pulveroboletus species in East Asia and North/Central America.
