Xenopyricularia belongs to the family Pyriculariaceae (Ascomycota), and it was typified by Xenopyricularia zizaniicola (Klaubauf et al. 2014). The distinguishing features of Xenopyricularia include erect, subcylindrical, brown, smooth, branched, flexuous conidiophores with terminal to intercalary, denticulate, pale brown conidiogenous cells and obovoid, solitary, 2-septate, pale brown conidia with a prominent protruding basal hilum (Klaubauf et al. 2014). To date, two species of Xenopyricularia have been reported, but in 2024, Xenopyricularia junci later was transferred to Nothopyricularia junci (Feng et al. 2024). This genus is phylogenetically closely related to the genus Pyricularia but morphologically varies because of the presence of wider and more ovoid conidia, sometimes with irregular pigmentation, than Pyricularia conidia (Klaubauf et al. 2014).
Type species: Xenopyricularia zizaniicola (Hashioka) Klaubauf, Lebrun & Crous.
Other accepted species: Species Fungorum – search Xenopyricularia
