[Daily article] December 9: Exsudoporus frostii

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.
