Morphological and molecular methods were used to identify the statues of an isolate, EFY-36, a taxolproducing endophytic fungus. Based on the morphology of the fungal colony, the mechanism of spore production and the characteristics of the spores, the isolate is Mucor spp. Furthermore, the analysis of 18S ribosome RNA sequence of the isolate was achieved using PCR technology. The results showed that the 18S ribosome RNA sequence of the isolate has a higher homology relationship with other taxolproducing endophytic fungi; Pestalotiopsis sp., Seimatoantlerium sp. and Pestalosphaeria sp.
