Anyone ID this weird algae

[_Alex_]

I know what the red and green algae is lol no help needed on it. It's the weird soft plating algae I need an ID on. Started growing on a chalice I got and just is weird. Lol very soft feeling but rubbery. Any help with it and how to eliminate it would be great.

Thanks
