Amanita pantherinoides, commonly known as the western panther ^[2] or western American false panther ^[3] is a species of mushroom in the family Amanitaceae. It is poisonous, containing ibotenic acid and muscimol. ^{[4] [2]}

Taxonomy

Amanita pantherinoides has long been thought to be the same as the species Amanita pantherina , which has similar morphology under certain environmental conditions and at certain stages of maturity, but it is now considered to be a distinct species. ^[2] A. pantherina occurs in Europe and western Asia, ^[5] while A. pantherinoides occurs in western North America. ^[3] Another species with similar morphology, Amanita multisquamosa , occurs in eastern North America. ^[6]

Description

Amanita pantherinoides has a light brown cap that is about 4–10 cm (1.6–3.9 in) wide. ^{[2] [4]} The cap has white warts that sometimes wash off. ^[2] The stipe is about 5–12 cm (2.0–4.7 in) tall and about 1–2 cm (0.39–0.79 in) wide. ^[2] The mushroom has a ring and a volva. ^[2]

Habitat and ecology

Amanita pantherinoides is mycorrhizal and grows under conifers, especially Douglas fir. It is usually found in forests, but occasionally cities as well. ^[2]
