There is also a Mycotoxin ATP Inhibitor called Tri-Nitro-Propionic Aci, which causes complete organ failure after a couple of days of being unconsious. It generally only gets produced by certain fungal strains such as tropical Arthrinium, but can also be a very small percentage biproduct in some biofuel production methoda which utilize propionibacteria to conver grains and grasses similarly to how yeast creates alcohol.
