doesn’t really look like E. granulatus to me, although it certainly is in what is currently called the E. granulatus group. Specifically the peridium of this obs. is quite thick, the gleba is chambered, and the peridium does not appear to be covered with thick rhizomorphs. Were they cleaned?

Thank you Daniel

I remember us having this conversation last year. I have added photos of the interior.

There really is no way of knowing

whether this is E. granulatus and E. muricatus (or any other Elaphomyces species) without seeing the interior and peridium. E. granulatus does not have spores embedded in the peridium; E. muricatus does; several other Elaphomyces remain in question here. Both E. granulatus and E. muricatus have warted peridium exteriors.
