Abstract:: In order to identify the taxonomic status of a polypore specimen collected from Guangdong, China, the macro morphology and microstructure of its fruiting body were observed, the translation elongation factor 1-α gene (tef1) gene was sequenced, a phylogenetic tree was constructed based on Maximum Likehood (ML), Maximum Parsimony (MP) and Bayesian Inference (BI) analyses using the tef1 sequences. Morphological observation shows that the specimen has the same characteristics with Fomitopsis durescens specimens collected from Venezuela and USA; in the tef1 gene phylogenetic tree, the specimen collected from China and a F. durescens specimen collected from Venezuela clusters together forming a highly supported lineage (MP=95%, BS=87%, BPP=0.99). Therefore, the specimen collected from Guangdong, China is identified as Fomitopsis durescens, the identification of its taxonomic status lays a foundation for the biological characteristics research and the development and utilization of wild polypore specimens.
