Laccaria amethystina

Species of fungus

Laccaria amethystina, commonly known as the amethyst deceiver, or amethyst laccaria, is a small brightly colored mushroom, that grows in deciduous and coniferous forests. The mushroom itself is edible, but can absorb arsenic from the soil. Because its bright amethyst coloration fades with age and weathering, it becomes difficult to identify, hence the common name "deceiver". This common name is shared with its close relation Laccaria laccata that also fades and weathers. It is found mainly in Northern temperate zones, though it is reported to occur in tropical Central and South America as well. Recently, some of the other species in the genus have been given the common name of "deceiver".
