Despite its morphological distinctness, the family remained molecularly uncharacterized. In this study, we investigated the morphology and phylogenetic position of 16 strains determined as members of two Chlorochytriaceae genera, <i>Chlorochytrium</i> and <i>Scotinosphaera</i>. The phylogenetic reconstructions were based on the analyses of two data sets, including a broad, concatenated alignment of small subunit rDNA and <i>rbc</i>L sequences, and a 10-gene alignment of 32 selected taxa. All analyses revealed the distant relation of the two genera, segregated in two different classes: Chlorophyceae and Ulvophyceae. <i>Chlorochytrium</i> strains were inferred in two distinct clades of the <i>Stephanosphaerinia</i> clade within the Chlorophyceae. Whereas clade A morphologically fits the description of <i>Chlorochytrium</i>, the strains of clade B coincide with the circumscription of the genus <i>Neospongiococcum</i>. The <i>Scotinosphaera</i> strains formed a distinct and highly divergent clade within the Ulvophyceae, warranting the recognition of a new order, Scotinosphaerales. Morphologically, the order is characterized by large cells bearing local cell wall thickenings, pyrenoid matrix dissected by numerous anastomosing cytoplasmatic channels, sporogenesis comprising the accumulation of secondary carotenoids in the cell periphery and almost simultaneous cytokinesis. The close relationship of the Scotinosphaerales with other early diverging ulvophycean orders enforces the notion that nonmotile unicellular freshwater organisms have played an important role in the early diversification of the Ulvophyceae.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Morphology and phylogenetic position of the freshwater green microalgae <i>Chlorochytrium</i> (Chlorophyceae) and <i>Scotinosphaera</i> (Scotinosphaerales, ord. nov., Ulvophyceae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:51.728803","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Chloroplast; Scotinosphaera ","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-05-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000314925100012","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/jpy.12021"},"refs":null,"anarec":{"AnaID":256273,"PubliDate":2013,"Pagination":"115-129","XtraPublOfAnaID":null,"ISBN":null,"Volume":"49","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43251,"SerRR":"Journal of Phycology.
