| Abstract: | The molecular evidences which prove the asexual stage of Cordyceps sinensis is Hirsutella sinensis. rDNA ITS from Cordyceps sinensis,Hirsutella sinensis, Paecilomyces sinensis,Paecilomyce gunin were sequenced and compared The results indicate that C sinensis and H sinensis have the highest homology (97 8%), while they have less similarity with the other 3 species(less than 70%), which suggested that the asexual stage of C sinensis should be Hirsutella sinensis |
