Species 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.
基于形态学以及对核糖体DNA（rDNA）区域的分子系统发育分析，对中国粉牛肝菌属（牛肝菌科，牛肝菌目）物种进行了研究。该核糖体DNA区域包括内转录间隔区1和2、5.8S核糖体DNA（ITS）以及核糖体28S DNA D1 - D2结构域（28S），同时还分析了翻译延伸因子1 - α基因（TEF1）的序列。在中国共确认了9个物种，其中3个为新描述物种：黄鳞粉牛肝菌、红鳞粉牛肝菌和近红粉牛肝菌；5个为先前已描述的分类群：褐点粉牛肝菌、褐鳞粉牛肝菌、大孢粉牛肝菌、网盖粉牛肝菌和中华粉牛肝菌；剩下1个暂定为近里德利粉牛肝菌，将在未来进一步研究。提供了该属中国分类群的检索表。出乎意料的是，当前研究未发现粉牛肝菌属物种在东亚和北美/中美洲存在间断分布的种群。
