Whereas more recent species descriptions and identifications are mainly based on cell wall structures and the use of cultures, comparisons with molecular phylogenies are largely lacking. In this study, the phylogenetic relationships between 22 clones identified as Desmodesmus costato-granulatus (Skuja) E. H. Hegew. were assessed using ITS2 rDNA sequence data in combination with cell wall morphology. The unrooted ITS2 phylogeny showed that the clones cluster into five groups, which also differ in their cell wall structures. Therefore, the taxon is split into five species: D. costato-granulatus, D. elegans, D. fennicus, D. regularis, and D. ultrasquamatus. Compared with other Desmodesmus species, intraspecific sequence variation is extensive and may contain additional (pseudo)cryptic diversity. Compensatory base changes were near-absent within the species and varied from one to 11 between species. Relationships among the species were unresolved. Despite this, they clustered together with the two other Desmodesmus species having a combination of small and large warts in a well-supported lineage. Remarkably, ITS2 sequence variation in this lineage is as high as between all other included Desmodesmus species, even though the morphology of its members is rather uniform. 000056272 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000056272 588__ $$aDataset connected to Web of Science, Pubmed 000056272 65320 $$2Author$$acell wall structure 000056272 65320 $$2Author$$acompensatory base change 000056272 65320 $$2Author$$aDesmodesmus 000056272 65320 $$2Author$$aITS2 rDNA 000056272 65320 $$2Author$$anew species 000056272 65320 $$2Author$$asecondary structure 000056272 65320 $$2Author$$aspecies delimitation 000056272 7001_ $$0P:(DE-Juel1)VDB575$$aHegewald, E.$$b1$$uFZJ 000056272 7001_ $$0P:(DE-HGF)0$$aBraband, A.$$b2 000056272 7001_ $$0P:(DE-HGF)0$$aKitschke, M.$$b3 000056272 7001_ $$0P:(DE-HGF)0$$aFriedl, Th.$$b4 000056272 7001_ $$0P:(DE-HGF)0$$aSabbe, K.$$b5 000056272 7001_ $$0P:(DE-HGF)0$$aVyverman, W.$$b6 000056272 773__ $$0PERI:(DE-600)1478748-9$$a10.1111/j.1529-8817.2007.00325.x$$gVol. 43, p. 378 - 396$$p378 - 396$$q43<378 - 396$$tJournal of phycology$$v43$$x0022-3646$$y2007 000056272 8567_ $$uhttp://dx.doi.org/10.1111/j.1529-8817.2007.00325.x 000056272 909CO $$ooai:juser.fz-juelich.de:56272$$pVDB 000056272 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000056272 9141_ $$y2007 000056272 9131_ $$0G:(DE-Juel1)FUEK407$$bErde und Umwelt$$kP24$$lTerrestrische Umwelt$$vTerrestrische Umwelt$$x0 000056272 9201_ $$0I:(DE-Juel1)ICG-3-20090406$$d31.10.2010$$gICG$$kICG-3$$lPhytosphäre$$x1 000056272 970__ $$aVDB:(DE-Juel1)88248 000056272 980__ $$aVDB 000056272 980__ $$aConvertedRecord 000056272 980__ $$ajournal 000056272 980__ $$aI:(DE-Juel1)IBG-2-20101118 000056272 980__ $$aUNRESTRICTED 000056272 981__ $$aI:(DE-Juel1)IBG-2-20101118 000056272 981__ $$aI:(DE-Juel1)ICG-3-20090406
