@ARTICLE{TreeBASE2Ref17190, author = {Rikke Reese N?sborg and Stefan Ekman and L. Tibell}, title = {Molecular phylogeny of the genus Lecania (Ramalinaceae. lichenized Ascomycota)}, year = {2007}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Mycological Research}, volume = {}, number = {}, pages = {}, abstract = {The molecular phylogeny of the lichen genus Lecania was investigated using nucleotide sequences from the mitochondrial small subunit ribosomal RNA, the internal transcribed spacer region of the nuclear ribosomal DNA, 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, maximum likelihood, and maximum parsimony 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. Lecania 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.} }
