摘要

A new thermotolerant species, Paecilomyces biformis isolated from a soil sample collected in Tengchong Geothermal National Geopark, Yunnan Province, PR China is described and illustrated. This fungus can be easily distinguished from the other species of the genus Paecilomyces by the biform sporogenous structure consisting of phialides that are borne singly and finite conidiophores, finely echinulate stalks of the conidiophores and large conidia. On PDA plates containing different concentrations of O-methoxyphenol, the fungus exhibited laccase activities. A key to the accepted thermotolerant species of Paecilomyces is provided.
