Small growths on rock

[Allen glover]

Just bought some mushrooms on a rock and while temp acclimatising them I noticed these growths on the rock . Look like sponges of some kind but there are quite a few on the rock any ideas thanks

Vermedit snails. I’d suggest snapping them off and/or putting a dab of super glue over the opening.

Ty but I’ve never seen them white like that? all the vermetids I’ve seen are red they are hard like vemetid shells though

 

[NatD]

Yeah, can be light colored too. Do they put out snot strings?

Don’t know yet have it in quarantine for the moment will see how they go
