Type speciesHarposporium anguillulae Lohde

Notes: Most species in this genus were reported as pathogens of nematodes and sexual morphs of this genus are podocrella-like (Quandt et al. 2014, Spatafora et al. 2015). Species of the genus infect nematodes and rotifers and have ascospores breaking into lanceolate multi-septate part-spore, spherical or hirsutella-like conidiogenous cells, and crescent-shaped or helicoid conidia (Quandt et al. 2014, Spatafora et al. 2015) (Adopted from Hyde et al. 2020)
