I’ve added another cross-section photographed today that more clearly shows the purple spore mass, and I agree that this is Calvatia cyathiformis rather than craniformis.

Thanks for your email. I’d say your dead on about it being a puffball. I was only saying it looked boletoid, and indeed, the section shouts its true identity.

cool…and unusual.
