ID help?

Tiny white dots, like empty shells on frag, also Help ID these Mushrooms?
Thanks, Debra

Spirinoid snail shells...harmless.

I don't know mushroom IDs, though.

Additionally, at the base of that LPS stalk is a bristle worm. The mushroom is a Blue Mushroom (Actinodiscus)

Yeah, I’ve got it done pat to harvest the Bristle worms, stir up sand bed alittle with a long net, wave them up and I pick them up with my hand and throw in trash. I don’t mind them, only when they are visible! Thanks for the ID. I bought a 10 pound of live rock back in the late 90’s, mushrooms started to show up 2 or 3 yrs later. The’re all over the tank, main mushrooms on rock will expand 5 or 6 “”
