Retiboletus taxonomy

According to Zeng and Wu (2016), there are at least three accepted species of Retiboletus in the eastern USA: griseus, ornatipes, and retipes. The last one is split into two species, only one of which contains retipolides B & D. The one containing the chemicals (of northern distribution) is closely related to R. flavoniger, whereas the other one (southern distribution & Central America) is closer to R. sinensis of East Asia. And then there is that pine-loving fuscus -
like “griseus” from the Atlantic coastal plains that apparently didn’t make it into the paper.

Variety fuscus…

I was puzzled by these. Maybe something else?

Dark extreme?

Do the caps on these seem about as dark as the fruitbodies of this species ever gets?
