Macro algae? Or other?

Google images thinks it’s a land mushroom. It’s on an oyster I got at a market. Thought I would try that oyster thing in the tank theory while my tank is all inverts. Also, I really wanted the barnacles and limpets that were on the shells. *grins shamelessly*

I believe it’s snail eggs of some sort
Look up tulip snail eggs

I looked up tulip snail eggs. Close, but no cigar. I have them in a place where I will be keeping an eye on them to see what happens.

Edit: thank you for the starting point! This seems to look closer and seems logical. Leafy hornmouth snail.

There was another thread somewhere about egg cases that looked like that. Somewhere in this forum I think but it was late last night and I haven’t had my coffee yet this morning
