..may be colored enough for plumbeoviolaceus.

thanks for following up. I am still thrashing out those Eastern boletes myself!

It’s possible that these were a different Tylopilus species. I’ve added a couple of more photos from that group which do show a little more color on the stems. The first photo was in direct sunlight which I think washed out some of the stem details. Also, in the latest Orson and Hope Millers’ North American Mushrooms, they state that the stipe of T. plumbeoviolaceus has " a white bloom at first" and “white at the base”. Could be a Louisiana thing?!?

gorgeous tylopilus…

…but it can’t be plumbeoviolaceus with that pale stipe. see description in Bessette’s bolete book.
