Golden-pored boletes
Aureoboletus is a branch of the Boletaceae family which is known for its exceptionally bright yellow/golden pores, from which it's name derives.
Brown cap
This finely velvety brown cap, sometimes with a rosy tinge will be found growing around oaks alone or with others nearby. The cap often extends just beyond the pore layer, seen in this image as a light-colored layer at the edge of the cap (the margin). When wet, the cap may be viscid (sticky or slimy).
The stipe
The fresh stipe will be noticeably viscid (sticky/slimy), white mycelium, and rosy streaks that run up the otherwise light-tan stipe.
Because they are sticky, we suggest trimming off that dirt so that you don't have to wash them as much later.

Here you can see the deep pore-layer that does not change color when cut or bruised. The context (inner cap flesh) is white.
Stipe structure

Other than the rosy streaks, the stipes are un-ornamented and distinctly lack reticulation, puncta, or scabers. You may notice some of the pores nearest to the stipe have been streched into a slight pseudoreticulation on the apical (top)-most region. Furthermore the rosy-cinnamon color of the stipes becomes more apparent with repeated handling.

The pores will be easy to remove from the pileus (cap) with a fingernail. This is often used as a identification characteristic for many fungi.

A. auriporus has another feature that separates it from other boletes with 'yellow' pores, its tart. Unlike the tasting of many other boletes that requires a bit of a chew, a casual lick of A. auriporus will be sour.
As with all wild mushrooms, make sure they are cooked thoroughly before consumption.
