Pyriculariopsis parasitica (= Pyricularia musae) was recognized as differing from Pyricularia by the absence of a septum to separate its denticles from the conidiophore (Ellis 1971). In a molecular study, Bussaban et al. (2005) found Pyriculariopsis was outside a clade of Magnaporthaceae. However, they concluded that Pyriculariopsis should be maintained based mainly in its straight or curved, obclavate and rostrate conidia. Soares et al. (2011) suggested an additional feature to delimit Pyriculariopsis, which was consistently observed or illustrated for most species, as pointed out by Whitton et al. (2001). Pyriculariopsis contains two distinct ecological groups, one is composed of saprobes occurring on foliar and stem debris and the other includes plant pathogens on monocot hosts in Zingiberales (Soares et al. 2011, Uchida & Kadooka 1994).

Type species: Pyriculariopsis parasitica (Sacc. & Berl.) M.B. Ellis.

Other accepted species: Species Fungorum – search Pyriculariopsis.
