摘要: The relationship between teleomorphs of Cordyceps spp. and their presumed anamorphs have been investigated by analysis of 5.8S and ITS rDNA sequences. The morphological and sequence data confirm that Paecilomyces hawkesii is the anamorph of Cordyceps gunnii, while Cordyceps hawkesii is a synonym of C. gunnii, and P. gunnii is a synonym of P. hawkesii. The following presumed connections are also confirmed: Beauveria brongniartii is the anamorph of C. brongniartii, Metarhizium anisopliae var. majus is the anamorph of C. brittlebankisoides, Beauveria sobolifera is the anamorph of C. sobolifera, Mariannaea pruinosa is the anamorph of C. pruinosa, Paecilomyces militaris is the anamorph of C. militaris, and Hirsutella sinensis is the anamorph of C. sinensis. The other isolates sequenced are unlikely to be anamorphs of the teleomorphs from which they were isolated because the sequences from the culture and the teleomorph are quite different. 5.8S and ITS sequences provide useful information for establishing anamorph-teleomorph connections and assisting in the delimitation of species within Cordyceps.
