The Most Poisonous Mushroom on the Planet

Mushrooms have mitochondria. They breathe in oxygen and they exhale carbon dioxide, but yes, fun, fun G a hundred percent respire. I don't think it's witches butter though because there's so many mushrooms that have like crazy names like death cell mushroom or like the blow kill you in your sleep mushroom. And I have a feeling one of those is probably the most poisonous. So for that reason, I think witches butter sounds like food. It would be named more like bleh. Let's go.
