One of the greatest challenges for anyone trying to identify this very common member of the Amenita genus is its tremendous variability. However, the pinkish colouring on the cap would indicate that this is probably a Rubescens (this epithet means reddening and refers to the colour from white to pinkish red when cut or damaged flesh of either cup or stem is exposed to air).
