Taxonomy

The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich. The type genus is Irpex.[1] Later multi-gene phylogenetic analyses of the Polyporales supported the use of this family. In these analyses, Irpicaceae is a sister taxon to the Meruliaceae; these two families, as well as the Phanerochaetaceae, form the phlebioid clade.[2][3]

Description

Irpicaceae has both polypore and crust fungi. They have a monomitic hyphal system, containing only generative hyphae that do not have clamp connections. Their spores are thin-walled, smooth, and translucent. Cystidia are often absent from the hymenium. More rarely, some species are dimitic and/or with cystidia and/or clamp-connections present; for example, Emmia and Irpex have cystidia, and there are clamp connections in Gloeoporus. Irpicaceae fungi produce a white-rot, except for one brown-rot genus (Leptoporus).[3]

Genera

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.[3]

Morphological variety of Irpicaceae
  • Corticioid: Byssomerulius corium
  • Flabelliform: Hydnopolyporus palmatus
  • Polyporoid: Trametopsis cervina
gollark: I even fixed some of them.
gollark: PotatOS has so many bugs it's somewhat funny.
gollark: You, or someone else, has to explicitly specify in detail what exactly you want, in Lua, and then spend a while debugging it because you probably got it wrong.
gollark: It's not a matter of there just being magic commands to make the computer do exactly what you want.
gollark: That seems like a dodecahedral attitude.
