Certainly in the E. granulatus group.

Has visible spores within the gleba, which pretty much defines E. granulatus group. Unfortunately, the genus is in need of revision. I found something in the Columbia River gorge several years ago. Had fascinating spores: both red and green. Looked like a color-blindness chart under 100×.
