Here we used information on six gene regions, three nuclear protein-coding markers (<jats:italic>Mcm</jats:italic>7, <jats:italic>GAPDH</jats:italic> and <jats:italic>Tsr</jats:italic>1), two nuclear ribosomal markers (ITS and IGS) and a partial mitochondrial small subunit (mtSSU), to examine infrageneric relationships in the genus and to assess species delimitation in the <jats:italic>Bryoria bicolor</jats:italic>/<jats:italic>B</jats:italic>. <jats:italic>tenuis</jats:italic> group in section <jats:italic>Divaricatae</jats:italic>. For this purpose, phylogenetic analyses and several of the available algorithms for species delimitation (ASAP, GMYC single, GMYC multiple and bPTP) were employed. We also estimated divergence times for the genus using *BEAST. Our phylogenetic analyses based on the combined data set of six gene loci support the monophyly of sections <jats:italic>Americanae</jats:italic>, <jats:italic>Divaricatae</jats:italic> and <jats:italic>Implexae</jats:italic>, while section <jats:italic>Bryoria</jats:italic> is polyphyletic and groups in two clades.

Separate phylogenetic analyses of section <jats:italic>Divaricatae</jats:italic> using ITS produced a topology congruent with the current species concepts. However, the remaining gene regions produced poorly resolved phylogenetic trees and the different species delimitation methods also generated highly inconsistent results, congruent with other studies that highlight the difficulty of species delimitation in groups with recent and rapid radiation.
