The genus was introduced based on morphology to accommodate five of the six <i>Piricaudiopsis</i> species that exhibited holoblastic conidial ontogeny. <i>Xiuguozhangia</i> was referred to as Ascomycota genus <i>incertae sedis</i> as it was challenging to resolve its taxonomic placement based solely on the available morphological data (no DNA sequence data was previously available).
