Poisonous mushrooms in Norway

​Edible, inedible and poisonous mushrooms all grow in the forest. Some of the most poisonous mushrooms that grow in Norway can easily be mistaken for edible mushrooms gathered in other countries. Contact the Poison Information Centre (22 59 13 00) if you suspect poisoning.

Amanita muscaria

Amanita muscaria var. muscaria.

Good advice when picking mushrooms:

  • Only eat mushrooms you are 100% sure are safe.
  • Never try to taste an unknown mushroom! Even a poisonous mushroom can have a mild flavour.
  • Use up-to-date literature on mushrooms.
  • Throw away all worm-eaten or rotten mushrooms.

Dangerous misidentification​​

Deadly webcap grow in the same places as the edible Trumpet chanterelle (Craterellus tubaeformis), and the two species are similar in colour (see photo). It is important to check each mushroom you collect to make sure the deadly webcap is not mixed in with any edible chanterelles.

Other poisonous mushrooms

These three agaric mushrooms contain a toxin that affects the nervous system. Clinical signs usually appear ½ - 3 hours after ingestion. Small amounts ingested may cause confusion, dizziness and stomach upsets. Ingestion of larger amounts can cause muscle tremors and other symptoms requiring hospital treatment.

Orange birch bolete is edible if heated for a minimum of 15-20 minutes. Orange birch bolete insufficiently heated is probably the mushroom causing most cases of stomach upsets in Norway.
