Recognized by sight: just plain calopus is the preferred name on Index fungorum. Without the aerolate cap, not sure how you would get it to the frustosus variety anyway…

Boletus calopus var. frustosus

After several tastings, this mushroom was deemed to be bitter. The nearest tree was Sitka spruce. Since the European B. calopus favors hardwoods and looks a little different, this should probably be called B. frustosus.
