Distribution and Habitat
The two-colored bolete is distributed from southeastern Canada and the Great Lakes Region, primarily west of the Rocky Mountains, as far south as the Florida peninsula, and out to the Midwest as far as Wisconsin. It is commonly found in deciduous woodland and usually grows under or close to broad-leaved trees, especially oak. It can be found in isolation and in groups or clusters, primarily during June through October. The two-colored bolete is also found in China and Nepal, where it is one of the most used mushrooms of over 200 species of edible mushrooms used in Nepal. This unusual distribution of the two-colored bolete and other mushrooms is known as the Grayan disjunction; the phenomenon is characterized by a species living in one continent or island and then also on the other side of the world with no specimens of the species living in between the specific habitats. The Grayan disjunction is not uncommon among fungi.

—Cyril Connolly (1903–1974)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
