White small ‘bits’ on the wood ornaments

These have appeared since having snails, one type is vampire x2 but the other 2 I’m unsure of.
is this snail eggs or fungus? Never seen it before ?

Nerite snail eggs. The good news is they won't hatch in freshwater so you won't be over run with snails. The bad news is that they won't hatch so you're stuck with spotty wood, I'm afraid. You can try to scrape them off, but all that happened when I tried that is I pulled off chunks of wood. They are easy to scrape of hard things like glass but not wood in my experience.
