Dinoflagellate ID

[Asmolupers]

I’ve searched the web trying to ID this and it looks a lot like Alexandrium Catenella. The only problems is, I thought that type was a cold water type. Also, I searched the whole slide for a chain of these and couldn’t find any. The pic is a cluster of them which aren’t moving at all. Anyone know what exactly this is?

Im not sure how to edit my post but, it appears to be coolia which makes more sense.

The dinos are indeed coolia.
[tagging @Dan_P for the excellent pic of the cyanobacteria that doesn't look like the kinds that I grow, nor really like the kinds he grows either. This has more constriction at cross-walls and flatter, more coin-like cells. sounds more like textbook oscillatoria maybe..]

This is a professional, high resolution photomicrograph!

I have seen hints of cell walls like this in some of my Oscillatoria cultures lately. I wonder if their prominence means anything
