Ken: I found these north of Vernonia under a mixed conifer forest with some alder trees near some manmade lakes. The caps are very dark brown to almost black and the young caps have a white film over them. The flesh is white and does not stain for the most part except where the tubes were removed with some bluing in places. Another point is they are almost worm free, quite rare in my experience with collecting boletus edulis.
Dick: The only other species that resembles B. aereus (now regineus) is B. fibrillosus. The pictures of your collection show young pores that are stuffed (covered with white material) and hoary coating on some of the caps which pretty much narrows it down to B. aereus / regineus.-
