Genus Irpex
[milk tooth polypore]
We have one widespread species here in North America.
- Irpex lacteus
This second list is names that have been used for Chicago Region, such as by Moffatt (1909) and Harper, and their current status.
- Irpex ambiguus = Hyphodontia spathulata [one 1902 collection at FH and one at UC].
- Irpex cinnamomeus = Hymenochaetopsis olivacea [common].
- Irpex fuscescens = Hymenochaetopsis olivacea.
- Irpex nodulosus Peck = Status unknown; assumed synonym of Irpex lacteus if not a Xylodon.
- Irpex tabacinus = Hymenochaete odontoides [Ginns (1998): only in southern United States.]

- Taxonomy
- I have not been able to find a phylogeny of species described as Irpex. The few papers that describe a new species of Irpex have ignored the other species described the previous decade(s). Apparently it is no longer a monotypic genus (having only one species).
