Mitogenomics, phylogeny and morphology reveal two new entomopathogenic species of Ophiocordyceps (Ophiocordycipitaceae, Hypocreales) from south-western China.

ABSTRACT: Ophiocordyceps encompasses over 300 species, demonstrating a wide range of morphological features, hosts and habitats within its species diversity. In this study, two novel species in Ophiocordyceps were revealed parasitising Hepialidae larva buried in soil. Ophiocordycepsalbastroma was morphologically characterised by white stromata, solitary and cylindrical conidiogenous cells and smooth ovoid or ellipsoidal conidia. Ophiocordycepsnigristroma was characterised by woody and dark brown stromata, monophialidic, swollen base and lageniform conidiogenous cells and smooth fusiform or oval conidia. The two new species formed a separate clade, respectively, based on the phylogenetic analyses of a combined dataset including nrSSU, nrLSU, rpb1, rpb2, and <
