The tubular layer is first medium-porous, then dissected, with elongated, characteristically sinuous pores, inclined towards the base, grayish, gray-cream, gray-brown.
The flesh is leathery at first, then hard, corky, separated from the upper felt layer by a thin black stripe, whitish or yellowish, with a sharp spicy smell.
