What You Should Know
Amanita citrina is an inedible mushroom with a fleshy pale yellow, or sometimes white cap. It is a very common mushroom that grows in most parts of mainland Europe and North America.
Although known to contain the toxin alpha-amanitin and bufotenin but if eaten in normal amounts the concentration is so low that it is unlikely to have any significant effect on a healthy adult. Anyway, Ultimate Mushroom doesn't recommend collecting and eating this mushroom.
Other names: False Death Cap, Citron Amanita.
