Extract from Wikipedia article: Laccaria amethystina, commonly known as the amethyst deceiver, is a small brightly colored mushroom, that grows in deciduous as well as 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".

Laccaria amethystina is a species of fungus that belongs to the family Hygrophoraceae. It is characterized by its small to medium-sized fruiting bodies, typically 1-4 cm in diameter, with a wavy or lobed cap that ranges in color from pale purple to amethyst. The gills are crowded and narrowly attached to the stem. In East and Central Texas, Laccaria amethystina has been found growing in association with oak trees, particularly in sandy soils and wooded areas. It typically fruits from late summer to early fall, often in areas with rich organic matter. Specimens have been collected in counties such as Travis, Bastrop, and Gillespie, where it can be found in woodland edges, clearings, and along trails.

Spores of amethyst deceiver mushrooms (Laccaria amethystina) (spore print white, cap turns whitish after drying) collected on Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest north from Montgomery. Texas, March 24, 2024Observations of Laccaria amethystina in East and Central Texas show that the fungus grows in various locations, including Big Thicket National Preserve, Sam Houston National Forest, and Lick Creek Park. The mushrooms were found in different habitats, such as wet areas, under pines, and near creeks. They were observed during different times of the year, from November to April, with multiple sightings in December. The caps of the mushrooms were often amethyst-colored, but turned whitish after drying. The gills were also observed, and spore prints were taken, which were white. The mushrooms were found singly or in groups, and their sizes varied. Overall, Laccaria amethystina appears to be a relatively common species in East and Central Texas, with a wide range of habitats and growth patterns.
