Hairy Mushroom or Rock Flower Nem

[Steelheader09]

I bought this a while back, LFS said hairy mushroom but just didnt look right to me. Any thoughts? Ignore the turf algae, its. Work in progress.

Looks like a hairy mushroom to me, I have a couple and they’re the same texture. Rock nems are usually pretty smooth in the middle and just have the lil tentacles around the outside edge

Rock nems don't have branching tentacles. Pretty sure its a hairy mushroom.
