Of the various types of mushroom toxins, those which cause the greatest number of deaths are the amatoxins and orellanine.
The sinisterly named ‘Death Cap’ and ‘Destroying Angel’ mushrooms both contain amatoxins. The amatoxins are a family of structurally similar compounds, with minor changes in parts of the structure determining the different types, of which ten are currently known.
