Exsudoporus frostii, Frost's bolete, is a fungus first described in 1874. The mushrooms it produces have tubes and pores instead of gills on the underside of their caps. E. frostii is distributed in the eastern United States from Maine to Georgia and Arizona, and south to Mexico and Costa Rica. It is typically found associating with hardwood trees, especially oak. Its mushrooms can be recognized by their dark red sticky caps, the red pores, the network-like pattern of the stem, and a variable blue-staining reaction after 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.
