摘要

A common cicada pathogen occurring in bamboo forests of southern China is described as a new species, Tolypocladium dujiaolongae. The previously unknown anamorphic state was obtained from discharged ascospores. Based on its morphological characteristics and a molecular analysis of the internal transcribed spacer rDNA sequence, we found that the asexual features of T. dujiaolongae are similar to those of Tolypocladium species. The typical characteristics of the fungus are described. The fruiting bodies formed on artificial culture media were identical to those of natural specimens, strongly supporting the idea that the isolated strain is the asexual stage of T. dujiaolongae. Our results indicate that there is no relationship between Tolypocladium dujiaolongae and the famous traditional Chinese medicine Isaria cicadae.
