I recently bought a microscope hoping to learn more about algae and bacteria and stuff. I've collected a few samples of pond water and found tons of algae and stuff, but I have no idea what to call the things I have found. I am wondering if there is a list of every known algae with a picture and some characteristics that would help me identify what I am looking at. I've looked around on the internet and haven't found much. Thanks
I do not know how complex of a key you want, but this one is a good identification guide for beginners. It contains a lot of common freshwater pond algae, what they look like, and some basic characteristics. From here, you can identify your specimen and then be able to look them up further. Hope this helps!
