Speedbumps On The Road To Barcoding Agarics.

The movement toward barcoding life has gathered some momentum in mycology, although some major obstacles still remain. Among the regulations and conventions being promulgated by the barcoding community is one which will prove particularly problematic for the mycological community: one barcode per species. Inherent is a definition of “species,” which for some agarics has been investigated to various resolutions. At stake is whether a species is defined morphologically, genetically or molecularly. Also of increasing interest is the biogeographical partition of “species,” to which phylogeographic data are contributing, and from which geographic population the single barcode should be derived. Examples include Marasmius scorodonius, and M. androsaceus, Lactarius volemus, the Megacollybia platyphylla complex, Lentinus tigrinus and Sarcodon imbricatum. Haphazard and/or capricious barcoding will lead to significant misinformation for meta-data, informatics, ecology and modeling, much less systematics. It is suggested that the barcoding effort must conform to the normal rules and recommendations of nomenclature
