Irish checklist:

A Preliminary Check-list of the Algae of Ireland has been produced by Michael D. Guiry (September, 2019).

The preliminary check-list of current names for freshwater, marine and terrestrial (including aerophytic) algae of Ireland is extracted from the distributional data in AlgaeBase (http://www.algaebase.org) as of September 2019, and each name and its source is traceable on-line there. Some 2,879 current species names are presently included. Nine phyla/divisions are included, eight of them from the Eukaryota and one (Cyanobacteria) from the Prokaryota.

National checklists are available for desmids (John, Williamson & Guiry,2011) and seaweeds (Guiry 2012), and for diatoms by Carter in Wolnik & Carer (2014).

Number of algal species:

2,879 known species (but exact number is likely to exceed 5,000 species, or about 10% of the world’s species of algae)
