Multilocus-phylogeny of the lichen-forming genus <i>Bacidia</i> s. str. (<i>Ramalinaceae</i>, <i>Lecanorales</i>) with special emphasis on the Russian Far East

Abstract To clarify deep relationships among species lineages within Bacidia s. str., and to investigate the robustness of deeper branches, we combined data from three traditionally used RNA-coding genes (nrITS, nrLSU mtSSU) with two protein-coding ( RPB 1 2). The multigene phylogeny contained 48 newly generated sequences Russian Far East all str. GenBank (131 sequences). We subjected alignments for single concatenated sets Bayesian inference (BI) maximum likelihood (ML) analyses (RAxML IQ-TREE). topologies phylogenetic trees recovered BI ML were highly concordant. multilocus was congruent previous results based on nrITS but considerably higher support values most branches. A correlation between clades apothecial pigments in upper part hymenium lateral exciple observed. Based morphological molecular evidence, obtecta is described as new science. It sister lineage B. elongata . are alike having up four enlarged lumina cells along edge, differs abundant crystals found exciple, by spores fewer septa.
