Abstract
Recent phylogenetic studies of the family Hydrodictyaceae (Sphaeropleales, Chlorophyceae) included all but one of the genera, Euastropsis, which was excluded due to a lack of living material. A 2017 discovery of E. richteri in Lake Kocie, Poland, provided an opportunity to study the morphology, ultrastructure, plastome architecture, and phylogenetic placement of this monotypic genus. The overall morphology fit the original description, being two-celled with some variations in size and number of daughter coenobia. The plastome (GenBank accession PQ469705) architecture and gene content of E. richteri are characteristic of Hydrodictyaceae. Phylogenetic analyses placed E. richteri as a sister lineage to morphologically similar Stauridium tetras. These new data add to our understanding of evolutionary trends in the Hydrodictyaceae, whose members exhibit specific colonial morphology varying in size, shape, and complexity.
期刊介绍：
The Journal of Phycology was founded in 1965 by the Phycological Society of America. All aspects of basic and applied research on algae are included to provide a common medium for the ecologist, physiologist, cell biologist, molecular biologist, morphologist, oceanographer, taxonomist, geneticist, and biochemist. The Journal also welcomes research that emphasizes algal interactions with other organisms and the roles of algae as components of natural ecosystems.
