Identification of growth

[Pridedcloth3]

After a year of not being a member but still getting answers here I finally found something not posted here lol. Story goes I bought a couple shrooms from a lfs and when I got home I noticed this growth wrapped around the rock. Wondering if anyone knows what I got my hands on.

Could we get images under white light (ex. with a flashlight)?
Seems to me like:
Black encrusting matter - Sponge
Sticklike protrusions - Sponge
Pink encrusting matter - Coralline algae
Red encrusting matter - Peyssonnelia

Hang tight the limited file size did me in because I had a really good picture that wouldn't upload

It's not letting me upload and I cut 80% of the picture
