Molecular phylogeny and morphology reveal two novel entomopathogenic species of Hypocreales (Polycephalomycetaceae and Cordycipitaceae), from China.

ABSTRACT: Based on an integrated taxonomic approach combining multi-locus phylogenetic analysis and morphological characterization, we formally describe and illustrate two new entomopathogenic fungal species from China, Pleurocordyceps longiphialis and Samsoniella aggestitenuipes. Phylogenetic analyses of a six-locus dataset (ITS, nr SSU, nr LSU, tef1-α, rpb1, and rpb2) strongly support the distinct phylogenetic positions of the two new species within their respective genera. Morphologically, P. longiphialis, isolated from a Scarabaeoidea larva, possesses notably elongated α-phialides (9.5-101 µm) and dimorphic conidia. In addition, S. aggestitenuipes, obtained from a lepidopteran pupa, displays synnemata with powdery conidial masses and phialides mea
