Amanita is the mother fungus of a gigantic colony of ancient and extremely dangerous fungi. During a scientific exploration in Australia, researchers discovered a colossal underground forest, however... The forest was strangely taken over by orange-white fungi, from the trees to the ground and rocks everything was infested by fungi. Until one of the researchers, Doctor Mabel Rainn, ended up literally being devoured by the forest... The ground opened and she was taken to the heart of the forest.
