I had noticed the orange stains on the stipe, but not really noted it as distinctive. Thanks!

R-b. griseus

Yep, I am finding these now under pine in the NJ pine-oak barrens. Some of these have red-staining stipes. I think this might be a subspecies of R-b. griseus because of it’s association with conifers and distribution in the acidic sandy soil of coastal plain. The regular griseus, which I have collected before, grows stricly under hardwoods, as reported in B-R-B.
