{"doi":"10.5507/fot.2023.013","title":"A new terrestrial species of Diplosphaera (Trebouxiophyceae), Diplosphaera sundellii, from a sodic-saline slick in Warren Prairie Natural Area, Arkansas, USA","abstract":"<i>Diplosphaera</i> Bialosuknia emend Vischer (Chlorophyta; Trebouxiophyceae) is a very small green alga commonly found as a photobiont in lichens and free-living in soil. Cells of <i>Diplosphaera</i> are spherical or nearly so and often grouped in short chains. There is essentially no morphological variation among the strains of the single recognized species of this genus<i>, D. chodatii</i>. In our study of the soil algal communities of Warren Prairie Natural Area in southeast Arkansas, USA, we isolated several strains that matched the morphological characteristics of the genus <i>Diplosphaera</i> from the biotic crust of a sodic-saline slick. Phylogenetic analysis of DNA sequences from the ribosomal RNA internal transcribed spacer regions (ITS) and the plastid rbcL gene indicated that the Warren Prairie strains are a new species. This conclusion was also supported by analysis of the secondary structure of the ITS2. All of our results support the description of the new species, <i>Diplosphaera sundellii</i>.","journal":"Fottea","year":2024,"id":461930,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.942,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":729677,"name":"Marvin W.
