The phylogeny of nematode-endoparasitic Hirsutella species was studied based on morphology and DNA sequence analysis. Hirsutella vermicola is proposed as a new species that preys on bacteria-feeding nematodes and nonpathogenic or weakly pathogenic to plant-parasitic nematodes. It is distinguished from H. rhossiliensis by having shorter conidiogenous cells with a swollen base, helical necks and slightly wider conidia. Phylogenetic trees based on sequences of the ITS region, MAPK gene fragment, and the combined data revealed two clusters corresponding to these two species and thus supported the establishment of this new species.
