oliveisporus and pulverulentus could indeed be close genetic relatives, but macroscopically they are readily separable — see BRB. I have never found the bolete in obs 208605 outside of the Pine Barrens ecosystem. I am pretty sure its host is the pitch pine.

Look at the similarities…

between this obs and Igor’s obs 208605. I was once asked how I separate the two species. Seems that oliveisporus has a southern range that peters out south of PA.

Around here I apply the name pulverulentus to collections from several different habitat… near an apple tree and not far from a hickory in my yard (no oak), hemlock-dominated woods, and (rarely) oak-dominated woods.

Nice find, John

It’s been awhile since I saw these last time…
