Etymology

Phalloidin comes from the mushroom name Amanita phalloides; the part phallo- is from Greek phallos meaning 'phallus', -oid means 'like', and -in marks a protein, so the name points to a protein from that 'phallus-like' mushroom and explains why phalloidin is the toxic peptide found in the death cap.
