Sometimes learning the most deadly plants and fungi is a good starting point, if you can avoid them you’ll stay safe.

This blog post is supposed to instill a little fear in the learning and budding forager, but only in so much that we all understand the risks and are respectful and wary of what we’re doing as foragers.

Mushrooms in the UK are something that we’re not very well accustomed to, I remember specifically from when I was younger that mushrooms you can look at and enjoy but that’s as far as you should go, touching or picking one up was even something that wasn’t advised. We thought maybe the toxins could enter straight through the skin and kill us dead, right there on the spot – so we must quickly wash our hands.

As professional foragers, we’re now trying to educate people on the wonders of the wild world and all things edible, medicinal and useful through our foraging courses. Part of this is, of course, Wild Mushrooms. Whilst we’re out it’s as important, if not more important, to learn about the common toxic species we’ll come across as well as the deadly toxic species and potential toxic lookalike species we’ll often find when out hunting for those edible gems.

So here are eight mushrooms that every forager should either be familiar with or should definitely get familiar with:

Our top 8 Toxic UK Wild Mushrooms

Sulphur tufts

not the most toxic but they are so, so common that cases of poisoning do occur. I find this mushroom nearly every time I head to walk through any woodland. I’ve even looked at potential ways of making this mushroom edible through boiling, salty and fermenting – to no luck.

Brown Roll Rims

Brown roll rims – a very common mushroom, they are eaten in some parts of the world but are considered toxic in the UK and are potentially deadly. The toxins cause your immune system to attack red blood cells.

Panther caps

listed as being deadly in lots of guides, they contain psychoactive compounds similar to Fly agarics (muscarine) and consumption can be fatal. Symptoms include severe vomiting and diarrhoea.

Funeral bells

As the name suggests one to avoid as it contains the same toxins as the Death cap.

Death caps

The most toxic mushroom found in the UK, with no known antidotes. They contain the compound A-amanatin which kills liver cells. The symptoms of severe vomiting, diarrhoea and abdominal pains start several days after consumption, these can last several days after which you appear to make a full recovery before dying a few days later of organ failure.

Destroying Angels

Very similar to the Death cap in the way that this mushroom kills you. There’s a couple of species of woodland living agaricus species that I imagine, when they’re very young, people may have confused this mushroom with. I could also think for a beginner, when this mushroom is REALLY small and still in it’s sack it has the potential to be confused with one of the puffballs – although on cutting it in half you would see there’s a baby mushroom in there not just white flesh.

Deadly fibre caps

The Deadly Fibre Cap Contains a deadly amount of the toxin muscarine which causes gastric upsets, excessive sweating, slower heart rate and can lead to death. This mushroom grows in spring and the only thing you could potentially confuse it with is a St Georges Mushroom (ID guide here for St Georges Mushroom) and this would only happen when the deadly fibre cap is young and has white gills still.

Angel wings

Although once considered edible they are known to have caused fatalities in Japan and should therefore be considered deadly poisonous. An incident of Angel wing poisoning involving 59 people occurred in Japan in 2004 leading to the death of 17 people. The precious nature of how the toxins affect us is still unknown. This mushroom, without a doubt, will have been picked in the past mistakenly for an oyster mushroom. The key is that Angel Wings Mushrooms are pure white and almost ghostly in appearance. (Our Oyster Mushroom ID guide can be found here)

Yellow Stainer Mushroom

In no way is this mushroom the most deadly toxic in the UK, however we’ve included as this mushroom is the main culprit for poisonings in the UK. It’s often picked mistakenly for other species within the Agaricus family. You can learn more on this family of mushrooms here.

Well that just about summarises the most toxic and deadly mushrooms found growing throughout the UK – if you can think of any others then please let us know and we will add them to this list You can get in touch here

The key takeaways for me are:

1. Any mushroom with a Volva (growing from a sack) and having a skirt on the stem then be wary (Amamitas)
2. During spring don’t just think a white mushroom is a St George – always check it against Deadly Fibre Caps
3. Check Any Oyster Mushrooms against Angel Wings
4. Check any small mushrooms with a stem and gills, growing off wood, against funeral bells and sulphur tufts

We hope this guide helps,

Step into the enchanting realm of Brown Roll Rims, scientifically known as Paxillus involutus, as we delve into the captivating qualities of these intriguing mushrooms.

In this blog post, we embark on a journey to discover the unique characteristics and ecological importance of this species. With their distinct brown caps and rolled edges, Brown Roll Rims offer a subtle beauty that can be appreciated by mushroom enthusiasts and nature lovers alike.

Sadly not edible but something we come across quite literally every walk we go on.

Common names

Brown Roll rims, Common roll rim, poison pax

Botanical name

Paxillus Involutus

Meaning of Scientific classification

The name derives from Paxillus meaning small stake or peg and Involutus refers to the in rolled cap margin.

Class: Agaricomycetes

Order: Boletales

Kingdom: Fungi

Division: Basidiomycota

Could be confused with

Can look like some of the milk cap (Lactarius) species but these all exude a milk-like substance when damaged.

Distribution

Very common in the UK and Europe.

Key features and habitat of Brown roll rim mushrooms

Caps

Caps are typically around 6-20 cm in diameter. When young the caps are convex but soon flatten out with a slight depression towards the centre. As the common name suggests they are brown in colour, with faint striations along the cap margin.

Gills

The gills are pale yellow/brown, crowded and run partway down the stem, when damaged they bruise darker brown. The cap margin is in rolled hence the common name roll rim.

Habitat & Season

They form ectomycorrhizal relationships with both hardwoods and conifers and are most commonly found in late summer and autumn.

Spores

Brown – Yellowish/Brown

Edible uses

Although this species was eaten in the past and is still apparently consumed in Eastern Europe it was responsible for the death of the German mycologist Julius Schaffer in 1944. It has since been found to cause potentially fatal autoimmune damage by triggering your immune system to attack red blood cells leading to complications such as acute kidney shock and acute respiratory failure.
