Geographic distributions of mushroom-forming fungi usually remain elusive because the scarcity occurrence data. However, increasing number environmental and ectomycorrhizal (EcM) root tip DNA sequences deposited in public repositories provides a unique opportunity to expand our knowledge about fungal geographic distributions, even at intercontinental scale. Here, we present Cortinarius ochrolamellatus, new EcM species likely associated oak (Quercus spp.) Iberian Peninsula, Sardinia, Central Italy, France, Norway. The morphological phylogenetic study collections allowed us include it within C. section Laeti. Furthermore, combination specimen-based ITS data analysis revealed presence this Hyrcanian Quercus forests northern Iran. Hence, adds further evidence for biogeographic link between Europe these Asian mountainous concerning fungi. inferred Pleistocene temporal framework origin diversification events ochrolamellatus suggests that distribution was driven by its tree hosts during complex Eurasian Quaternary history.
