This species is closely related to Gomphidius roseus, from which it differs in the color of the stem, lamellae and flesh. The gluten of the pileus becomes blackish in drying and sometimes separates in a radiating manner, revealing the reddish color of the surface of the pileus. The mature lamellae appear velvety when viewed by the aid of a lens. This is due to the abundance of the prominent spores that cover their surfaces.
