Tells: Red to cinnamon, oft-viscid cap ages darker brown & has a sterile edge. Oft-viscid, oft-ridged stem enlarges going down, bends before snapping (think asparagus), & is cap colored low & lighter high.

Other Information: Pale yellow pores age to olive brown, DNS, & may be depressed by the stem. Cap may crack w/age & may taste sweet. White flesh may have a pale pink tint & sometimes stains blue. Likes oak & hemlock.

Science Notes: Formerly considered a version of Aureoboletus (f/k/a Boletus) auriporus. General distinctions include atkinsonianus growing bigger, getting darker pores w/age, tasting neutral to sweet rather than acidic to neutral, liking both oak and hemlock instead of just oak, and the bend-and-snap stem.
