For the past few weeks I’ve noticed these weird little green algae bowls growing on my rockwork… not sure if these are micro or macro so I apologize if I’m in the wrong spot. I can’t find anything resembling this anywhere but it’s hard to search when you don’t know what you are searching for… does anyone have any idea what the heck this algae is? Thanks for the help!

That's a macroalgae; closer/clearer pics could help with an ID here, but - since it looks translucent - early growth of an Ulva species like Ulva lactuca or Ulva expansa would be my guess.

If it is an Ulva species, those are generally considered good (they're great food macroalgae).
