标题：Morphological and genetic characteristics of the novel entomopathogenic fungus Ophiocordyceps langbianensis (Ophiocordycipitaceae, Hypocreales) from Lang Biang Biosphere Reserve, Vietnam
摘要：An entomopathogenic fungus newly named Ophiocordyceps langbianensis was collected from Lang Biang Biosphere Reserve, located in Lam Dong Province, Vietnam. It is characterized as a species of Ophiocordyceps (Ophiocordycipitaceae, Hypocreales) having the unique characteristics of a cylindrical fertile part and several branched apical appendices. Each ascospore develops as two swollen, constricted part-spores. A phylogenetic analysis of multiple genes, including nrLSU, nrSSU, Rpb1, ITS and Tef, supported its systematic position in the genus of Ophiocordyceps; it is related to O. brunneipunctata. Based on morphological and phylogenetic analyses, O. langbianensis was confirmed as a new species from Vietnam.
