In phylogenetic analyses based on the internal transcribed spacers and 28S nuc rDNA and translation elongation factor 1-α to compare Chinese white truffle specimens that have ascomata resembling the European Tuber borchii, the sequences of Chinese species resembling T. borchii in morphology grouped into seven distinct clusters among three clades: Puberulum, Maculatum and Latisporum No sequences from these Chinese species matched those of the European T. borchii and the occurrence of the European T. borchii in China could not be supported by our study. Three unknown species are recognized from the seven Chinese clusters; two are described here as T. hubeiense and T. wumengense based on molecular and morphological evidence.
在基于内部转录间隔区、28S核糖体DNA和翻译延伸因子1-α进行的系统发育分析中，为了比较具有类似欧洲波氏块菌子囊果的中国白松露标本，形态上类似于波氏块菌的中国物种序列在三个进化枝（粉状块菌、斑纹块菌和宽孢块菌）中分为七个不同的簇。这些中国物种的序列与欧洲波氏块菌的序列不匹配，我们的研究无法支持欧洲波氏块菌在中国的出现。从这七个中国簇中识别出三个未知物种；基于分子和形态学证据，这里将其中两个描述为湖北块菌和乌蒙块菌。
