Green stalks growing on snail shells?

[GobyGuy]

I have some green macro algae growing on the back of my snails. It seems to be a single stalk and is rather stuck on there, sometimes the stalks go white if they're surrounded by hair algae on the snails back. I will attach pictures later - does anyone know what I'm dealing with, without pictures

A picture is worth a thousand words:) Could it be https://www.reef2reef.com/threads/calcareous-growth-everywhere.888190/. ?

If it is an algae - it is not likely to be a problem causer

Added some pics, it seems extremely plant-y

growing directly on to the shell, or seems like it, pulling off tends to break the "stalk" as opposed to removing the entire "plant"

Neomeris algae:

Neomeris sp. This is a rare calcified green macroalgae that usually dies out in captivity. However, it has a rare chance to go invasive. Since it is calcified, I would assume few organisms could consume it besides urchins.

Agree it looks like a macro algae
