Earthball or potato earthball. Don't consume.

Scleroderma Citrinum

Hmm, I'm not so sure, I think that for Scleroderma the inside is a lot denser.

To me, these larger granules look more like a dyeball, Pisolithus arhizus: https://www.jungledragon.com/specie/8966/dyeball.html

Agreed, here's an earthball cross-section for comparison:

Any idea why it's called a dye ball?

From: https://www.fungusfactfriday.com/119-pisolithus-arrhizus/

The Dyeball, as its common name implies, can also be used for dyeing wool. P. arrhizus is counted among the best mushrooms for dyeing and imparts wool with a deep brown to reddish-brown to blackish color. The pigments come from the tar-like gel between the peridioles, so younger Dyeballs work better.

Nice, thank you!

This may also be of interest to you, even though they do not use this specific mushroom: https://www.youtube.com/watch?v=T4TjnxFO3yw

what a lovely explanation!

I don't know. The ball on the left is the cross section of the inside. I cut it through the middle.
