[Note Guidelines] Photographer's Note
Amethyst Laccaria, Laccaria amethystina, a denizen of the local Oak woods, it's mycorrhizal with Oaks, meaning that it's mycelium (thread-like underground part of the fungus) "interfaces" with the roots of Oak trees (also Beech, where they occur), acting like an extension of the tree's root system, providing water and minerals to the tree in return for sugars and amino acids from the tree. Many mushrooms are mycorrhizal, and many plants depend on their associated fungi to remain healthy.

This little species is a beauty. It starts out purple all over, then as it ages, its cap turns to pinkish and finally a buff color, while the gills retain their amethyst-purple color for a longer time.

A synonym for it is Laccaria amethystea.

The mushroom in the lower right corner is another species.

hi John,

Good sharpness and colours revealing lots of anatomical details of the mushrooms. About the ID, I'm a bit in doubt. I meet every fall L. amethystina in numbers and as a first remark, they are (like you said) purple all over, fading in pink on old exemplars. But in your photo, two out of three individuals seem to be fresh and young, yet the cap colour is pinkish and the gills purple-violet. That sends me to some similar species of Laccaria genus: L. bicolor, or maybe L. proxima which I also encountered and it looks exactly like in your photo.

Cheers, Petru

Interesting photo showing the species over it different colour ranges. Laccaria have wonderful spiny spores making them very distinctive microscopically.

The colors of these fungi are simply amazing John, excellent details..

Great post,

Good Morning John Denk. You must have quite the archive sir..A lovely bunch of cocnuts we have here..Nice colours. Quite the blend...I think I shall opt for the alternative of coffee and a roll..
