Amanita muscaria
fly agaric, fly amanita

Distribution: Broad

Habitat: Woodland

Substrate: Birch and conifers

Conservation Status: Not of concern

Edibility: Poisonous.



Identification Notes:

Spores are white. Growth of up to 8 inches. Cap diameter of up to 12 inches. All of the forms have striate cap margins, rings that may or may not persist into maturity, and volvas in the form of rings of loose tissue that extend part-way up the stipe from a bulbous base. Along with A. gemmata, A. pantherina, and A. aprica, all contain ibotenic acid. Thus, they cause accidental poisonings but also are sought after by some who seek their psychoactive effects, and A. muscaria has been used ritualistically in areas such as Siberia. A. regalis (Fries) Michael is a related brownish to ocher species that has a boreal distribution, including Alaska.
