    Description

    We are re-addressing species concepts in the Rhizopogon vinicolor species complex (Boletales, Basidiomycota) using sequence data from the interna transcribed spacer (ITS) region of the nuclear ribosomal repeat, as well as genoLypic data from five microsatellite loci. The R. vinicolor species complex by our definition includes, but is not limited to, collections referred to as R vinicolor Smith, R. diabolicus Smith, R. ochraceisporus Smith, R. parvulus Smith or R vesiculosus Smith. Holo- and/or paratype material for the named species is included. Analyses of both ITS sequences and microsatellite loci separate collections of the/7_ vinicolor species complex into two distinct clades or clusters, suggestive of two biological species that subsequently are referred to as R vinicolor sensu Kretzer et al and R. vesiculosus sensu Kretzer et al. Choice of the latter names, as well as morphological characters, are discussed.
