Alectoria is a genus of fruticose lichen characterised by the presence of usnic acid and conspicuous raised pseudocyphellae. This genus is particularly diverse and abundant in montane, boreal, and Arctic regions of North America. Because intermediate forms have been reported for several species of Alectoria on the continent, it has been suggested that these species were initially delimited based on the extremes of morphological gradients. Here, we use the results of molecular phylogenetic analyses of two nuclear genes, ITS and Mcm7, with 48 representatives of 9 taxa to examine the delineation of 5 taxa that have been previously shown to be related to, or confused with, A. sarmentosa: A. fallacina, A. imshaugii, A. sarmentosa var. sorediosa, A. sarmentosa subsp. vexillifera, and A. vancouverensis. Alectoria fallacina was found to be well-supported and distantly related to A. sarmentosa. Conversely, the other four taxa were recovered as a single monophyletic group with little internal structure, which did not ... : original alignment for ITSAlecITSNEX3.nexoriginal alignment for MCM7ALECMCM7NEX2.nexoriginal alignment for ITS+MCM7alectoria_ITS_MCM7_combined (1).nexinput dataset for ITS ML analysisAlecITSNEX4.phyinput dataset for MCM7 ML analysisALECMCM7NEX2.phyinput dataset for mtSSU ML analysisAlectoria_mtssu.phyinput dataset for ITS+MCM7 combined ML analysisML_alectoria_ITS_MCM7_combined.phyinput dataset for ITS+MCM7 combined BI analysisBI_Alectoria_COMBINED.nexoutput of results for initial mtSSU analysis with MLRAxML_bipartitions.Alectoria_mtssu_ML.pdfoutput of results for initial MCM7 analysis with MLRAxML_bipartitions.Alectoria_McM7_ML.pdfoutput of results for initial ITS analysis with MLRAxML_bipartitions.Alectoria_ITS_ML.pdfoutput of results for initial ITS+McM7 analysis with M_combinedRAxML_bipartitions.Alectoria_combined_ITS_MCM7_ML.pdf ...
