A key field character which distinguishes them from members of the genus Boletus is the presence of their pink-tinged pores (though these may be white when young). The "pink pore" feature is a polyphyletic morphology that does not unite the Tylopilus species using traditional morphological characters (Smith and Thiers or Singer's concepts).
A key feature that sets these fungi apart from members of the Boletus genus is their pink-tinged pores, though these may be white when they are young. The "pink pore" trait is a shared characteristic across various species but doesn't effectively group them together based on traditional morphological features (as described by Smith and Thiers or Singer).
