Hi @MirandaBCyano does come in black,red and blue green colour.
I've looked at them under the microscope but I'll be honest I'm not sure what I'm looking at and I'm not able to get a photo from the microscope,both are definitely some sort of Cyano though as when wiped off they're back the next day.Hi @MirandaB
I'm only familiar with the blue-green species. Do you happen to know which species of cyano are red and which are black?
TIA.

Hi @MirandaB...both are definitely some sort of Cyano though as when wiped off they're back the next day.
I don't think so,the rate of growth and the texture makes me think otherwise.
Hi @MirandaBIf you want to have a look at them,I'm more than happy to send you a sample of both in test tubes

Hi @Chris_HomanWhat algae would this be? I’m inclined to say brown algae but they grow most in direct light.
