Recognized by sight: Cracking peridium, probably a sterile base where the peridium is absent. If powdery consistency, then likely S. areolatum. If solid, S. cepa or other. Sclerodermas should be considered poisonous until proven otherwise. Be sure to wash your hands after handling.

Sorry it’s about 30 miles & I would have to cross the bridge and they just raised the tolls.

You’re very welcome.

But your comment was not what I was expecting to hear. Now I’m having second thoughts about the species. Solid typically refers to something similar to S. cepa or S. laeve, but both those species in my experience have much darker colored gleba (interiors). If these are nearby, could you dig the base and provide a photo of the fungus cut through the base?

A 110-pound pot-bellied pig died several years ago in Vancouver, WA after eating an unknown number of Sclerodermas in his yard. Pig and human physiolgy are so similar, that a human weighing the same amount eating the same quantity probably also would have died. Even immature Sclerodermas are known to cause extreme gastric upset. For more on the subject, read “Mushrooms: Poisons and Panaceas”.

Thanks Daniel!

This one felt solid and not powdery. Did not know that some are poisonous.
