摘要：
Species of Heimioporus (Boletaceae, Boletales) in China are investigated on the basis of morphology and molecular phylogenetic analyses of DNA sequences from the nuc rDNA internal transcribed spacer ITS1-5.8S-ITS2 region and nuc 28S rDNA D1-D2 domains (28S) and translation elongation factor 1-alpha gene (TEF1). Three species are recognized in China: H. conicus, sp. nov., H. gaojiaocong, sp. nov., and the previously described H. japonicus. Heimioporus xerampelinus, originally described from southwestern China, is synonymized with H. japonicus; specimens from China previously regarded as H. retisporus and H. subretisporus are confirmed to represent H. japonicus and H. gaojiaocong, respectively. A key to the Chinese taxa of the genus is provided. A preliminary biogeographical analysis shows that Heimioporus in East Asia and Southeast Asia/Australia are closely related. Heimioporus japonicus is a geographically widespread species occurring in East Asia and Southeast Asia; however, no taxa common to East Asia and Australia were uncovered.
