Tylopilus ferrugineus has a reddish-brown cap, initially white pores that become pinkish as its spores mature, and stain brown. It has a slightly duller reddish-brown stem that it whitish at the apex. It may or may not have reddish-brown reticulations on the upper half. This is a good edible.
Chemical test to ensure you have this species and not a bitter lookalike is to put a drop of ammonia on the cap. It will produce a dark purple or red flash before turning black. This Leccinum is in the Boletaceae family of the Boletales order..
