Spongy cyano??

[EeyoreIsMySpiritAnimal]

I found a small patch of dark red (algae/??) that's got a spongy texture and when I removed some, it seems like the underside is white-ish and stuck to the rock. (Kind of like peeling the top "skin" off cooked pudding.)
Is this another form of cyano or something else?

Cyano is like a blanket it does not realy stick you can dislodge it with a turkey baster.

Yeah, I know... which is why I'm not sure what this is. If I forcefully blow water at it with a baster, it does come loose a bit, but not like the cyano I've had in the past.

Is it all over or in one spot

I'll have to take a better look tomorrow when the lights are back up. I have a lot of dark red corilline so it's hard to tell.
