identify this mushroom

these guys came in on another coral as a hitchhiker and they have doubled in size over the past 6 months.
I actually really like the shape and semi-transparency of these guys.
I would like to know what they are so I can look up more and see if they are available in different colors.

Looks like a discosama. Different colors don't usually mean different species. Sometimes they turn translucent at the edge because of how thin they are. As it grows, I'd expect it to start coloring up.

I would like to point out that they are pretty uniform in shape, and have never had the wavy edges you see on other mushrooms.
The tops almost look fuzzy or hairy.

i have a pair of the exact same mushroom, and i never knew the name of them. Those are one of my favorite mushrooms in my tank, and probably will be the only ones i will keep when i transfer tanks.
