Pyricularia Sacc., Mycelia 2(no. 6): 20 (1880)
Index Fungorum number: IF9670; 44 morphological species (Species Fungorum 2020), 18 species with sequence data.
Type species – Pyricularia grisea Sacc.
Notes – The name Pyricularia refers to the pyriform shape of the conidia, which is a specific character of this genus (Bussaban et al. 2005). Pyricularia species can infect various monocotyledons including Cenchrus, Echinochloa, Lolium, Oryza, Pennisetum or Zingiber. Pyricularia oryzae is the cause of rice blast disease, one of the most important diseases of rice. Klaubauf et al. (2014) synonymised Magnaporthe grisea under Pyricularia grisea, by clarifying the taxonomic relationships among species that are magnaporthe- or pyricularia-like using molecular phylogeny (LSU, ITS, rpb1, act and calM).
