In these regions, the systematics and biogeography of <i>Clathromorphum</i> and <i>Phymatolithon</i> have mostly been resolved whereas <i>Lithothamnion</i> has not, until now. Seventy-three specific and infraspecific names were given to Arctic and Subarctic <i>Lithothamnion</i> specimens in the late 19th and early 20th century by Frans R. Kjellman and Mikael H. Foslie. DNA sequences from 36 type specimens, five historical specimens, and an extensive sampling of recent collections resulted in the recognition of four Arctic and Subarctic <i>Lithothamnion</i> species, <i>L. glaciale</i>, <i>L. lemoineae, L. soriferum</i> and <i>L. tophiforme</i>. Three genes were sequenced, two plastid-encoded, <i>rbc</i>L and <i>psb</i>A, and the mitochondrial encoded COI-5P; <i>rbc</i>L and COI-5P segregated <i>L. glaciale</i> from <i>L. tophiforme</i> but <i>psb</i>A did not. Partial <i>rbc</i>L sequences obtained from type collections enabled us to correctly apply the earliest available names and to correctly place the remainder in synonymy. We were unable to sequence another 22 type specimens, but all of these are more recent names than those that are now applied. It is difficult to identify these species solely on morpho-anatomy as they can all occur as encrusting corallines or as maerl (rhodoliths). We demonstrate the importance of sequencing historical type specimens by showing that the recently proposed North-east Atlantic <i>L. erinaceum</i> is a synonym of one of the earliest published Arctic species of <i>Lithothamnion, L. soriferum</i>, itself incorrectly placed in synonymy under <i>L. tophiforme</i> based on morpho-anatomy. Based on sequenced specimens, we update the distributions and ecology of these species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Lithothamnion</i> (Hapalidiales, Rhodophyta) in the changing Arctic and Subarctic: DNA sequencing of type and recent specimens provides a systematics foundation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:30.879227","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Coralline red algae; cox1; DNA barcoding; distribution; morpho-anatomy; psbA; rbcL; systematics; taxonomy; type collections","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2023-05-22","DateCreate":"2023-03-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000662139300001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/09670262.2021.1880643"},"refs":null,"anarec":{"AnaID":362318,"PubliDate":2021,"Pagination":"468-493","XtraPublOfAnaID":null,"ISBN":null,"Volume":"56","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42675,"SerRR":"European Journal of Phycology.
