The Pseudanabaenaceae are a family of cyanobacteria. The order Pseudanabaenales consists of this family and Thalassoporaceae (Thalassoporum).
Genera 2020s taxonomy The taxonomy as accepted by AlgaeBase and LPSN is based on Strunecký, Otakar, and Mareš (2023). This work includes two genera in the family, Limnothrix and Pseudanabaena. Because Limnothrix is polyphyletic with regard to Pseudanabaena, the two are likely to become one in the future.
