## In brief

- A Florida mushroom may contain both the psychedelic compound psilocybin and deadly amatoxins.
- Phys.org reports it is the first mushroom found to contain both kinds of compounds.
- Nature reports the fungus may use this chemical mix to defend itself against hungry animals.

## Why it matters

The finding challenges the common split between 'magic' psychedelic mushrooms and poisonous mushrooms, which matters for anyone trying to identify or handle wild fungi.
