The molecular phylogeny of the lichen genus Lecaniawas investigated using nucleotide sequences from the mt-SSU rRNA, the ITS region of the nu-rDNA, and the RNA polymerase II second largest subunit. Forty-six species representing Lecania and other genera likely to influence the phylogeny were included in the study. Phylogenetic reconstructions were carried out using Bayesian inference, ML, and MP approaches. Lecania, as traditionally circumscribed, is not a monophyletic genus. However, a monophyletic group containing a large number of Lecania species, including the type species L. fuscella, was discovered in the analysis, and recognition of Lecania sensu stricto is suggested. L. baeomma, L. glauca, L. gerlachei, L. brialmontii, L. racovitzae, L. hyalina (alias Biatora globulosa), L. chlorotiza, L. naegelii, and L. furfuracea do not belong in Lecania s. str., although the latter two are closely related to Lecania s. str. Representatives of the genus Bilimbia form a well-supported group, as does the ‘Thamnolecania’ group containing the Antarctic ‘Lecania’ species, L. gerlachei, L. brialmontii, and L. racovitzae. An alternative to recognizing these two genera would be a wider circumscription of Bilimbia to include the ‘Thamnolecania’ group as well as affiliated taxa.
