The death cap mushroom (Amanita phalloides) is considered one of the world’s deadliest mushrooms. The toxicity of the Amanita species is due to the presence of two groups of toxins known as amatoxins and phallotoxins, both made of multiple cyclic peptide chains (circular sequence of bonds). Do some research about the death cap and answer: What makes the Amanita phalloides toxins so harmful that even one cap can kill an adult?

Fungal infection can be defined as an infectious disease caused by fungi. A fungal infection is also referred to as mycosis. Fungal infections are contagious, spreading from person to person. Mycosis can be contracted even from an infected animal or contaminated soil. The most common symptom is skin rashes and vaginal discharge in females.
