The sterile base is not right for Calvatia either. But I’m not expert enough to suggest an alternative.

Agree wholeheartedly with the comments. This is extremely early for puffbals in this area. At first I thought it might be a late puffball frozen from last year but that doesn’t seem reasonable. But that might explain an older puffball that didn’t mature. The guess was following more than one key, but I’m looking for enlightenment on this one. The geometric pattern on the top was strange, also.

the glebal chambers of this fungus with Calvatia gigantea (Batsch) Lloyd (79195).

Doesn’t looks the same, does it?

I don’t know about Calvatia gigantea.

The gleba of this specimen has overly large chambers in the gleba (spore-producing area). They are large for almost everything, in fact. Not locules as I understand the term. Calvatia should be firm and nearly solid when young. This appears more spongy. Would appreciate more photos.
