This bolete has a stem that is deeply, coarsely reticulate and, when the mushroom is in the "button" stage, often as wide as, or even wider than, the cap. With development the stem stretches out dramatically, becoming notably long. The sticky cap is reddish to yellow or orange, and the non-bruising pore surface is yellow, becoming slightly greenish with age. Under the microscope, Aureoboletus betula features finely pitted spores.
Previous names include Austroboletus betula, Boletellus betula, Boletus betula, and Heimioporus betula. Recent DNA results (Kuo & Ortiz-Santana 2020) support placement in Aureoboletus. [1]
