Hello there!
Does someone know what these are? I find them regularly in my backyard pond.
Spring-like algae
Re: Spring-like algae
Can you give a rough idea of size? I would guess its cyanobacteria and you can see the slightly bigger heterocysts. Could be Dolichospermum. Keep in mind it might be toxic.
