Imagine a fungus slipping into your bloodstream, hijacking every single neuron and freezing you alive while it knits its own flesh with yours.

If you were an ant or a spider, that could be you — but thankfully, Ophiocordyceps doesn’t (yet) affect humans.

In this Microgreens episode, we’re peering into the terrifying and slightly creepy world of fungi.

In our main episode, we covered why fungi are important. Today, we’re getting into their dark side...

In this episode I share:

  • What the bleeding tooth fungus is and what it does
  • The real-life zombie fungus and why it won’t affect humans any time soon
  • How glow-in-the-dark mushrooms work
  • What the dead man’s fingers fungus is
  • The potential health benefits of lion’s mane mushrooms
  • What slime mould is and why it can move


Episode quote:

“In fact, we are closer related to fungi than they are to plants.”
