AlgaeBase

AlgaeBase is an online taxonomic database that provides comprehensive information on algae from around the world. It catalogs macroalgae and microalgae across major algal groups, including red, green, and brown algae, as well as other photosynthetic organisms traditionally treated as algae. The database aims to document scientific names and their authors, synonyms, taxonomic hierarchy, type specimens, distribution, ecology, and key literature.

Each taxon page offers classification, geographic distribution notes or maps, bibliographic references, and often links to images and specimen data. The data are maintained by a team of phycologists and are regularly updated to reflect current taxonomy and nomenclature. AlgaeBase is widely used as a taxonomic reference by researchers, educators, and biodiversity projects, and it serves as a gateway to related resources and journals.

Access is free via the AlgaeBase website, which provides search tools to browse by taxon, geography, or literature. The project began in the late 1990s and is associated with the National University of Ireland Galway; it is maintained and expanded by a dedicated team to reflect ongoing revisions in algal systematics.
