Boletus ornatipes or Retiboletus ornatipes
I love the color of this mushroom! It is mustard yellow! And note the ornate, netted pattern on the stipe (a reticulate stem)! The ornate-stalked bolete is mycorrhizal on hardwoods, and in fact we found all of these mushrooms in a mixed-oak forest at Pandapas Pond, in Montgomery County, VA in late August and September.
