Xerocomus silwoodensis is reported for the first time in Ukraine. For the specimens collected in Khmelnytskyi Region, descriptions of the macro- and microstructures and results of the ITS barcoding are provided. The authors also discuss differences between X. silwoodensis and related species of Xerocomus s. str. (X. ferrugineus, X. subtomentosus, and X. chrysonemus).

Keywords: Basidiomycota, Boletales, distribution, DNA barcoding
