A wild A-Wei-Mo specimen collected from Xinjiang was identificated with morphological methods. The results showed that it was consistent with the morphological characteristics of Pleurotus eryngii var. tuoliensis, but different from those of Pleurotus nebrodensis reported in Europe. In addition, the strain CCMSSC 02514 isolated from the wild mushroom specimen was analyzed with molecular menthods. Based on rDNA ITS sequences from the phylogenetic tree, the relationship among Bai-Ling-Gu in China, Pleurotus nebrodensis and Pleurotus eryngii var. ferulae in Italy, and Pleurotus eryngii are analyzed. The rDNA ITS sequences of CCMSSC 02514 and Pleurotus eryngii var. tuoliensis AFRL 6022 are identical. Combined with morphology and rDNA ITS sequence analysis, we considered that Bai-Ling-Gu in China is different from the European Pleurotus nebrodensis, and the former is a branch of Pleurotus eryngii evolved independently in China. The scientific name for the Chinese Bai-Ling-Gu in China should be Pleurotus eryngii var. tuoliensis.
