a Dendrogram based on the 18S rRNA gene sequence. Bootstrap values are given at the nodes. The scale bar represents the substitution percentage. Nitzschia communis was used as the outgroup. b Dendrogram based on the nuclear rDNA spacers’ sequence (ITS-1, 5.8 S gene and ITS-2). Bootstrap values are given at the nodes. The scale bar represents the substitution percentage. Stichococcus bacillaris was used as the outgroup. c Dendrogram based on the 18S rRNA gene sequence. Bootstrap values are given at the nodes. The scale bar represents the substitution percentage. Ankistrodesmus stipitatus was used as the outgroup. GenBank accession numbers follow the species name in parentheses
