>>2607876theres a couple of signs which are commonly shared across many mushrooms, but not all, that they have started to go bad which are
- dark spots
- soft spots
- slime film
- bad smell
- bruises
and probably others im not thinking off
Problem with almost every mushroom is that they usually have toxic lookalikes.
Picrel is how you can identify between a morel and a false morel for example so if you know what mushroom you're going to hunt for just look up the lookalikes and how to identify them.
If you just wanna randomly forage get a mushroom guide or join a local mushroom hunting group, they love sharing their knowledge
