The cap surface is smooth, peelable half-way through, matt in dry weather, but viscid under wet weather conditions.

The stem is cylindrical or thicker at the base, full then hollow, white and longitudinally veined, becoming greyish starting from these veins.

The flesh is white, firm, turning grey; its taste is mild at first then hot; the odour is faint, fruity; its texture is grainy (breaking like a chalk stick).
