How do you know if mushrooms are bad?

This is how you can tell whether mushrooms are still good

You can recognize fresh mushrooms by these characteristics:

  • closed, maximally half-closed head
  • Slats are light to medium brown
  • The hat and stem feel dry and firm
  • Interfaces are bright
  • Mushroom is crunchy and has a pleasant mushroom-earthy smell

  • Some mushrooms can be poisonous

If the mushrooms look and smell as described, they are still good and can definitely be used. Even smaller bruises - recognizable by the brownish discoloration on the hat and / or stem - are not a problem.

How do you recognize mold on mushrooms?

Sometimes fine, white threads can be seen on otherwise still good-looking mushrooms, which in advanced cases literally cover the mushrooms. This is not about mold, but about the mushroom mycelium, which now forms a new fungal network. It comes from the spores that even supermarket mushrooms secrete and can be safely eaten or removed by carefully rubbing with a paper kitchen towel. Such fruit bodies coated with mycelium can also be used to grow your own mushrooms.

When is it better to throw away mushrooms?

Mold on mushrooms is also never white, but mostly black. Please do not cut out this area and use the infected mushrooms anyway! Throw away mold-infested mushrooms or you are playing with your health. You should also throw away and, better still, not use mushrooms that have one or more of the following characteristics:

  • Fungus feels spongy to greasy
  • unpleasant, putrid smell
  • distinct brown or even black spots

If the mushrooms still smell good but have dark lamellas, cut surfaces are dark and the hat and stem have dark spots, they are no longer fresh. In such a case, however, they can still be used as long as you remove the stem completely and cook the mushrooms very well. Only the taste will not be as aromatic as with fresh mushrooms.


If you are on the safe side and want to use the freshest mushrooms possible, you can simply grow them yourself. This also works on the balcony, in the garden and even in the cool cellar.
