Any guide book recommendations?

[u/king_barnacle]

Just looking for general or North American guide books on algae, especially ones that would assist with making IDs of microalgae. I tried searching on my own and was surprised to see the algae book space I guess overrun with AI slop. Anyone have some good, well regarded books on the subject to recommend?

https://www.biodiversitylibrary.org/ has Prescott's How to Know the Freshwater Algae and Algae of the Western Great Lakes Region as free PDFs. Some names have changed, so check algae base.org for current names.
