Is this snail on my mushroom base?

[psott]

Over the last week or so I've noticed this one particular mushroom isn't opening normally and today I noticed what looks like a snail on the bottom? It could just be a snail shell as the mushroom was sitting in the substrate at one point but I'm looking for input. Thanks in advance!

Yes that is either a snail, or snail shell. Impossible to tell from here if there's an inhabitant.

Should I be concerned or likely harmless?

if your referring to the upside down pyramid that is white and brown striped, it looks like a trochus snail, a common aquarium snail. I have 10 of them in my tank.

I agree, the snail in the photo is a Trochus. A harmless algae eater. It won't hurt the mushroom. Check your parameters and flow.
