Magnaporthaceae are distinguished from Pyriculariaceae by their asexual morphs. For Magnaporthaceae, the morphology of phialophora- or harpophora-like species is characterised by falcate versicoloured conidia on brown, erect conidiophores. In the case of Pyriculariaceae, Pyricularia or pyricularia-like species are characterised by pyriform 2-septate conidia and rhexolytic secession.
