Amanita
An Amanita is a mobile fungus enemy found in Super Mario RPG: Legend of the Seven Stars. They live in the Forest Maze and disguise themselves as common curative Mushrooms (which are plentiful in the forest). When an unsuspecting mushroom gatherer approaches a concealed Amanita, the fungus creature will reveal itself and attack. However, not all Amanitas disguise themselves; some move freely on the ground while searching for intruders. One Amanita even hides in an underground bush and ambushes travelers that walk by.
In battle, an Amanita attacks by twirling into one of Mario's party members. Aside from its regular attack, Amanitas can use the special attack known as Sporocyst to turn others into fungi. As a Mushroom, a party member cannot attack, use items, defend, or even move. The only positive side effect of being turned into a Mushroom is that a party member's HP will slowly recover.
Since Amanitas are fungus-based, they may be distant relatives of Toads and Goombas.
The term "Amanita" refers to the genus name of certain species of poisonous fungi.
