Summary The identity of a recent Scottish collection thought to be Boletopsis leucomelaena was examined with the help of molecular techniques. This poroid fungus proved to be a new species of Boletopsis differing from the European species occurring with Pinus sylvestris, which should continue to be called B. grisea. The new name Boletopsis peplexa is introduced for all the Scottish collections with Pinus sylvestris.
