Nomenclatural and taxonomic changes
Most of the nomenclatural changes listed below have taken place since publication of the 2nd edition of The Freshwater Algal Flora of the British Isles in 2011. Always check names in AlgaeBase (www.algaebase.org) since the most authoritative and up-to–date source of information on currently accepted names. Please be aware that not all algal specialists necessarily agree with all the taxonomic and nomenclatural changes in AlgaeBase. Also listed below are new records for the British Isles published during the past seven years
Name changes will be regularly updated and information on recent nomenclatural has been published in the following articles have been published in The Phycologist and are available for downloading from the website of the British Phycological Society website (http://www.brphycsoc.org/phycologist.lasso).
The hundreds of taxonomic changes to the desmid genera Staurastrum and Staurodesmus proposed by Coesel and Meesters (2013, European flora of the desmid genera Staurastrum and Staurodesmus. KNNV Publishing, Zeist, Netherlands 357 pp.) are not listed here but are to be found in issue 87 of The Phycologist.
