Upon closer examination, it looks like, I think the word is "cavertine" formation, made from carbonites of limestone like found in caves. If you found it in an area with sedimentary deposits, like limestone, that is it.

Well, it sure is sedimentary in origin. What material is it? (check if it will react with vinegar, yes = limestone/calcite)
If not, it may be gypsum I suppose. Gypsum can be scratched by the fingernail, do the test in a slightly hidden spot.

I'm still betting on concretion, not all of them being round globes still makes it a prime candidate.
But please develop on why it isn't one. More info will help limit possibilities.
