A key to the British species of the genera Aureoboletus, Boletinus, Gyroporus, Phylloporus, Porphyrellus, Pulveroboletus, Strobilomyces and Uloporus based on habitat, microscopic and macroscopic features is discussed. Four species as yet unrecorded from the British Isles, Boletinus asiaticus, Xerocomus amarellus, Boletus vaccinus, Boletus badiorufus and seven species which could possibly be sought in one of these genera are included in the discussion for completeness; the latter are also included in the key.
