Habitat question

I was put off that trail by the habitat..“confined to the arid or semi-arid regions of western North America”. But now see that there is a “less warty species along the west coast”. Will make the change.

The western giant puffball is Calvatia booniana and this looks like it. It also lacks a sterile base as does Calvatia gigantea but instead of a smooth exoperidium it has one that breaks into large flat scales that become lightly pigmented in the center.
