Taxonomy
Type genus: Pyricularia Sacc. 1880
Type species:
The polyphyletic nature of Pyricularia has been resolved in 2014 leading to the definition of a new family, the Pyriculariaceae.[1] Phylogenetic analysis showed that three clear clades could be distinguished. One clade corresponds to Magnaporthaceae (based on Nakataea), and two other clades were defined as new families: Pyriculariaceae (based on Pyricularia), and Ophioceraceae (based on Ophioceras).
Description
The Pyriculariaceae that reproduce sexually form perithecial fruiting bodies (
Asexual morphs are
An identification key to genera of Pyriculariaceae is provided by Maharachchikumbura et al (2016).[2]
Differentiation from other families
Pyriculariaceae is distinguished from Magnaporthaceae by their asexual morphs. Pyricularia or pyricularia-like species are characterised by pyriform 2-septate conidia and rhexolytic secession. In the case of Magnaporthaceae, morphology of phialophora- or harpophora-like species is characterised by falcate versicoloured conidia on brown, erect conidiophores.[1]
Genera
Ecology
Pyriculariaceae are saprobic or plant pathogenic fungi on various plant hosts, commonly on monocots.[2] Their host spectrum includes many grasses (Poaceae), and also ginger, sedges, rushes and commelina.
Blast diseases by Pyriculariaceae are caused by use of an appressorium to penetrate the host.[3]
Economic significance
Species of Pyriculariaceae cause major diseases on grasses, among which
