Edible, inedible and poisonous mushrooms all grow in the forest. Some of the most poisonous mushrooms that grow in Norway can be very similar to edible mushrooms in other countries. Contact the Norwegian Poisons Information Centre (22 59 13 00) if you suspect poisoning.
Even very small amounts of these mushrooms can cause severe poisoning. Clinical signs occur after a minimum of 6 hours, and include watery diarrhoea, abdominal pain and vomiting. There is a high risk of life-threatening liver damage within 2 - 3 days.
If you suspect you have ingested this mushroom, contact the Norwegian Poisons Information Centre (22 59 13 00) for advice.
Amanita virosa (Norwegian: Hvit fluesopp)
The entire mushroom is white (cap, stem, gills and flesh). On the stalk there is a ring, but this might fall off. The base of the stalk has a sheeting volva (bag). Destroying angel is common in forests
Amantia phalloides (Norwegian: Grønn fluesopp)
The colour of the cap can vary from green to brown and yellow. The gills and the stalk are white. On the stalk there is a ring, but this might fall off. The base of the stalk has a sheeting volva (bag). Death cap is rare in Norway.
Lepiota castanea (Norwegian: Kastanjeparasollsopp)
The cap is red brown and scaly. The gills and flesh are white. The stalk is brown. This is a small mushroom.
Galerina marginata (Norwegian: Flatklokkehatt)
The cap and gills are yellow–brown. The stalk varies from grey to brown. This is a small mushroom, usually found in clusters on bark and tree stumps. Funeral bell is common in Norway.
Lepiota boudieri (Norwegian: Rustbrun parasollsopp)
The cap is bell shaped, yellow brown and scaly. The gills are white. This mushroom is small and grows in deciduous forests.
Even a very small amount of the two webcaps contains enough poison to cause severe kidney damage. Clinical signs do not appear until at least 2 days after ingestion. These include nausea, abdominal pain, malaise and increased or reduced amount of urine.
There is a high risk of developing severe kidney failure within a period of 3 – 10 days. If you suspect you have ingested these webcaps, contact the Norwegian Poisons Information Centre (22 59 13 00) for advice.
Cortinarius Rubellus (Norwegian: Spiss giftslørsopp)
The entire mushroom is reddish-brown (cap, stipe, gills and flesh). Deadly webcap is common in forests.
Cortinarius orellanus (Norwegian: Butt giftslørsopp)
Looks like the deadly webcap, but has a rounded cap. Fool’s webcap is a rare mushroom growing in deciduous forests.
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.
Amanita muscaria/ A. regalis / A. pantherina (Norwegian: Rød / Brun / Panter fluesopp)
These mushrooms have white gills and a stalk with a ring. The base of the stalk is bulbous. The cap is reddish or brownish in colour, usually with white spots.
These three agaric mushrooms contain a toxin that affects the nervous system. Clinical signs usually appear within ½ - 3 hours after ingestion. Ingestion of small amounts may cause confusion, dizziness and upset stomach. Severe poisoning is rare, but ingesting a larger amount can cause symptoms requiring hospital treatment.
Leccinum versipelle (Norwegian: Rødskrubb)
Orange birch bolete has a reddish-brown cap and black scales on a white stipe. When cut, the stem turns grey-blue. The mushroom is common throughout Norway.
Orange birch bolete is edible if heated for a minimum of 15-20 minutes. Insufficiently heated Orange birch bolete causes multiple cases of stomach upsets in Norway every year.
Nausea, vomiting, diarrhoea and abdominal pain typically occur a few hours after ingestion. Symptoms usually pass within 1-2 days. Ingestion of large amounts may cause severe gastric distress and require hospitalization.
Paxillus involutus (Norwegian: Pluggsopp)
This mushroom has a brown cap with rolled rim, brown stalk and gills that darken when applying pressure. Brown roll-rim is very common in Norway.
Brown roll-rim contains several different toxins and can produce varying symptoms. Vomiting, diarrhoea and abdominal pain may occur ½ - 3 hours after ingesting raw mushrooms. Repeated ingestion of heat-treated Brown roll-rim can cause serious poisoning with damage to blood cells and kidneys.
