Q

What is cordyceps? Why is it considered a zombie fungi?

A

Fungi
Because of its life cycle; Its spores release upon a small insect or maybe even a mammal and take control of it body and cause it to climb up a tree and death clamp onto a leaf. Then the spores will prosed to sprout out of the victims head and reproduce more spores, and the cycle continues.
