Taxonomic remark Ruggiero et al., 2015, consider the diatoms to be at class level (Bacillariophyceae) within a broader phylum Ochrophyta. However Medlin, 2016 (followed by AlgaeBase, 2021 version) treat the diatoms as a phylum (Bacillariophyta), with Bacillariophyceae one of the latter's three component classes. Latest treatment (Gury et al., 2023; AlgaeBase, 2025) treat diatoms as a subphylum (Bacillariophytina) within Heterokontophyta. [details]
