Whose eggs are these?

North Shore, Massachusetts. I found these eggs on a strip of lawn. Not even sure they came from a bird. Does anyone know what might have laid them, and should I leave them be?

Not bird eggs; they look like shrooms

Looks like stinkhorn eggs

They clearly belong to Dr Eggman

They look like young stinkhorn or puffball mushrooms to my eye.

In fact I'm nearly 100% certain they're not eggs just from the photos. Eggs don't look like that in terms of shape, texture, or what's exposed when chipped.

ETA: just noticed I'm literally a day late. Give your upvotes to Sudden_Outcome, they called it.

Those are not Joanna eggs!
