amanita pigments are highly water soluble, and are dimmed by the sun as well.

What I have noticed with this species is, when it has been dried by the sun like this specimen the pileus becomes very dark and almost black, if it has been raining the pigment gets washed out and gives the very pale coloured pileus.
I found another specimen today that has been rained on and looks very pale and the scales have also been washed off, I’ll make a new observation soon!

It’s good to see the return of
