The genus Proxipyricularia belongs to the family Pyriculariaceae and is morphologically similar to the type genus Pyricularia but phylogenetically forms a distinct lineage (Klaubauf et al. 2014). Proxipyricularia was proposed as a new genus together with the type species Proxipyricularia zingiberis. This plant pathogenic Proxipyricularia is mainly characterized by its cylindrical, erect, olivaceous to brown, septate conidiophores with terminal and intercalary conidiogenous cells, pyriform to obclavate with narrowed tips and rounded base, subhyaline to pale brown, and 2-septate conidia often with minute marginal frills (Klaubauf et al. 2014). To date, only one species of this genus has been reported. Previously, Proxipyricularia asari was introduced under Proxipyricularia, but recently, it was transferred to the genus Pyriculariomyces as Pyriculariomyces asari. Proxipyricularia zingiberis was previously described as Pyricularia zingiberis. But according to Klaubauf et al. (2014), Proxipyricularia zingiberis was phylogenetically distant from the Pyricularia clade and was placed in the sister clade of Neopyricularia.
