Common name: Milk-white Toothed Polypore.

Extract from Wikipedia article: Irpex lacteus is a common crust fungus distributed throughout temperate areas of the world. It is the type of the genus Irpex. Irpex lacteus is considered a polypore, but depending on growth conditions it can also produce a hydnoid hymenophore. Due to this variability and abundance of the species it has been described as a new species to science numerous times and subsequently has an extensive synonymy. The complete genome sequence of Irpex lacteus was reported in 2017.

Hungarian: Fehérbélű egyrétűtapló, Russian: Ирпекс молочно-белый, Swedish: Vittagging.
