 Exsudoporus frostii mushrooms can be recognized by their dark red sticky caps, the red pores, the network-like pattern of the stem, and the bluing reaction to tissue injury. Another characteristic of young, moist fruit bodies is the amber-colored drops exuded on the pore surface. Although the mushrooms are considered edible, they are generally not recommended for consumption because of the risk of confusion with other poisonous red-pored, blue-bruising boletes. E. frostii may be distinguished from other superficially similar red-capped boletes by differences in distribution, associated tree species, bluing reaction, or morphology.
