Laccaria amethystina Cooke

Laccaria amethystina, commonly known as the amethyst deceiver, or amethyst laccaria, is a small brightly colored mushroom. 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 L. laccata, which also fades and weathers. Recently, some of the other species in the genus have been given the common name of "deceiver".

IUCN: population narrative

The overall population size and trend are unknown.

IUCN: habitat narrative

The species forms ectomycorrhizal associations, primarily with species of Quercus and Fagus.

IUCN: threats narrative

No major threats have been identified.

IUCN: conservation narrative

Laccaria amethystina is likely to be a species complex with several proposed segregate species, each of which appear to be broadly distributed. Further taxonomic work is required.

IUCN: rationale

Laccaria amethystina sensu lato is distributed throughout the temperate northern hemisphere into Colombia in northern South America (Mueller 1992). Several segregate species have been proposed for Asian material (Vincenot et al. 2017). It is widespread associated with Fagaceae in North America into Colombia, and east into Eurasia where it forms ectomycorrhizal associations, primarily with species of Quercus and Fagus. It is assessed as Least Concern.
