Amethyst Deceiver

Laccaria amethystina, commonly known as the amethyst deceiver or amethyst laccaria, is a small, brightly colored mushroom whose amethyst hue fades with age and weathering, making it difficult to identify and giving rise to its common name; the name deceiver is shared with its close relation Laccaria laccata, which fades in the same way. It is found mainly in northern temperate zones, in deciduous and coniferous forests, though it has also been reported in tropical Central and South America, and it is edible but can absorb arsenic from the soil.
