@ARTICLE{TreeBASE2Ref16870, author = {Jorinde Nuytinck and Annemieke Verbeken and Steven L Miller}, title = {Worldwide phylogeny of Lactarius section Deliciosi inferred from ITS and glyceraldehyde-3-phosphate dehydrogenase gene sequences}, year = {2007}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Mycologia}, volume = {}, number = {}, pages = {}, abstract = {A phylogenetic analysis of Lactarius sect. Deliciosi was performed based on collections of all known species. Several samples of each species were included, originating from a wide geographic range. The two DNA regions we used (ITS and a part of the gene encoding glyceraldehyde-3-phosphate dehydrogenase), showed an incongruent phylogenetic signal. Much attention was paid to carefully observed macro- and micromorphological characters to draw taxonomic conclusions. We currently accept 38 taxa (31 species and 7 varieties) in Lactarius sect. Deliciosi on a worldwide scale; four species are new to science. More sampling is needed to resolve the status of the North American varieties. Our knowledge of the Asian species in this section remains fragmentary. The monophyly of the section and its position within Lactarius subgenus Piperites, as proposed in recent morphology-based classification schemes, is confirmed. The intrasectional relationships however, do not coincide with the colour of the latex (as previously supposed). Intercontinental conspecificity is very low in general. The name L. deliciosus is wrongfully applied in North and Central America and only two species seem to occur in both Asia and Europe.} }
