Perennicordyceps is a genus of clavicipitoid fungi in Polycephalomycetaceae , comprising primarily entomopathogenic species, with some species also associated with fungal hosts. Its diversity and host range remain poorly understood, particularly in biodiversity-rich regions such as southwestern China. In this study, two new species of Perennicordyceps are described based on morphological characteristics and multigene phylogenetic analyses (nrLSU, ITS, nrSSU, tef -1α, rpb 1, and rpb 2). A new host record is also reported, expanding the known ecological range of the genus. Phylogenetic analyses place the new taxa within Perennicordyceps as distinct, well-supported lineages. Morphological comparisons with related species further support their recognition as novel taxa. This study improves the understanding of species diversity, host associations, and evolutionary relationships within Polycephalomycetaceae .
