• The paper reports and discusses some interesting findings of two southern boletes – Exsudoporus permagnificus and Pulchroboletus roseoalbidus - in association with the non-native for Europe Quercus rubra (Northern Red Oak). Descriptions and illustrations of the studied collections are provided, along with molecular phylogenetic analysis of the ITS sequences, confirming their affiliation. These are the first records of Exsudoporus and Pulchroboletus species with this host-tree. An overview of earlier reports of boletes with tubulate hymenophore with Q. rubra in Europe is provided and compared to data from North America.

  The authors also report another character for setting apart E. permagnificus from the members of the genus Butyriboletus, an earlier suggested affinity. Some findings related to the distinction of the European members of Pulchroboletus and Alessioporus are also brought forward.
