B. fumosus occurs on similar substrates in our area. It differs from B. adusta by having thicker flesh and buff to pale smoky gray pores and a dark line above the base of the tubes (cut through fruitbody). Both these fungi could be mistaken for species of Stereum or Trametes. The former, however, have a smooth surface under the cap, while the latter have white to pale gray pores and their caps are more or less zonate.
