 Pseudopyricularia, belongs to the family Pyriculariaceae (Ascomycota), is morphologically similar to the type genus Pyricularia but differs in having determinate, short, brown, finely roughened conidiophores with a rachis with flat-tipped denticles (Klaubauf et al. 2014). Pseudopyricularia was proposed as a new genus together with the type species, viz. Pseudopyricularia kyllingae. This plant pathogenic Pseudopyricularia possesses distinct characteristic features such as hyaline, branched, smooth, septate hyphae with solitary, branched or unbranched, erect, brown, septate, conidiophores; terminal, sometimes intercalary, integrated, brown, finely roughened conidiogenous cells, forming a rachis with flat-tipped denticles; and obclavate, solitary, pale brown, finely roughened, guttulate, 2-septate conidia with truncate hilum (Klaubauf et al. 2014). To date, 12 species of Pseudopyricularia have been reported. Pseudopyricularia is phylogenetically distant from the Pyricularia clade and is placed in the sister clade of Macgarvieomyces (Klaubauf et al. 2014).
