The death cap mushroom is one of the deadliest poison fungi on earth. Few effective treatments are available. But a team of Chinese and Australian scientists say they've made a leap forward.

Cases of the fungus that did not respond to antifungal medicine tripled in 2021. It can be deadly, but does not seem to have adverse effects on healthy people.

In the hit HBO show, the world has been devastated by a pandemic caused by a deadly fungus. Is that even possible? Could the next pandemic come from fungi? Turns out it's a very real question.
