The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales.
The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich.
In these analyses, Irpicaceae is a sister taxon to the Meruliaceae; these two families, as well as the Phanerochaetaceae, form the phlebioid clade.
[3] According to Justo and colleagues, several genera from various other Polyporales families contain species that should be in the Irpicaceae, and will need to be reclassified.
These include: Candelabrochaete (C. langloisii and C. septocystidia), Ceraceomyces (C. eludens, C. microsporus, and C. serpens), Ceriporia (C. lacerata), Ceriporiopsis (C. aneirina and C. resinascens), Hapalopilus (H. ochraceolateritius), Phanerochaete (P. allantospora, P. angustocystidiata, P. exilis, P. ginnsii, P. intertexta, P. leptoderma, and P. xerophila), and Phlebia (P. albida, P. albomellea, and P. nitidula.
