Abstract:Different species concepts are summarized, potentials and limits of Barcoding in Leccinum s.l. are discussed, and a combination of ecological, morphological and genetical species concepts are recommended and used in this paper. The status of the genus Leccinellum as an entity for yellow, blackening leccinoid boletes is discussed and confirmed. Two new sections are described as new. The European species of the sections Leccinellum and Calida are discussed and delimited. As results Boletus tlemcenensis is considered as an older name for Boletus lepidus and is transferred to the genus Leccinellum. Furtherly the following new combinations are made: Leccinellum aberrans (replacing Leccinum blumii, the former nomen novum für Boletus aberrans), Leccinellum rugosiceps, L. pseudoscabrum var. brunneobadium, L. pseudoscabrum f. pseudocarpini.
