What kinds of poisonous mushrooms are found in Saskatchewan?

Types of poisonous mushrooms in Saskatchewan

If you spend time outside, you’ve probably asked this question at least once. Poisonous mushrooms definitely have an infamous reputation.

Below, I have listed common poisonous mushrooms you can expect to find in Saskatchewan. But in NO WAY is this a complete listing of dangerous fungi. There are thousands of mushrooms in North America, so reviewing and writing about every toxic species is nearly impossible.

IMPORTANT: I can’t stress enough that you should NEVER eat a mushroom you find. As you will see below, there are many poisonous types, and some species will kill you. So stay safe, and don’t eat any wild mushrooms unless you are with a mycologist (mushroom expert)!

7 Poisonous MUSHROOMS in Saskatchewan:


#1. Lilac Bonnet

  • Mycena pura

Also called Lilac Mycenas or Lilac Bellcaps.

Types of poisonous mushrooms in Saskatchewan

  • The caps begin as lilac or purple and bell-shaped but flatten and fade to other shades, including whitish, yellowish, pinkish brown, or reddish as they age.
  • The stems are smooth and white or flushed with the cap’s color.

These toxic mushrooms are one of the most beautiful fungi in Saskatchewan. Their unusual lilac coloring makes them a treat for hikers and adventurers to spot as they grow on the ground of coniferous and hardwood forests. Their radish-like odor can also help you to distinguish them.

Despite all their charm, Lilac Bonnets are fun to look at but not to eat. These mushrooms contain several toxic compounds.

Lilac Bonnets contain sesquiterpene, which can cause vomiting, cramps, and diarrhea, and strobilurin, which is often used in agricultural fungicides.

They also contain small amounts of muscarine, which causes symptoms like blurred vision, excessive sweating, increased salivation, and abdominal issues.

Interestingly, Lilac Bonnets weren’t always thought to be toxic. It’s possible to find older mushroom field guides that list Lilac Bonnets as edible.


#2. Splitgill Mushroom

  • Schizophyllum commune

Types of poisonous mushrooms in Saskatchewan

  • The caps are 1–4 cm (0.3–1.6 in) wide.
  • They are pale white or gray and grow in stacked clusters that resemble shelves.
  • As its name suggests, the gills of this mushroom are spaced apart like individual threads.

These toxic mushrooms thrive in Saskatchewan on decaying trees during rainy periods.

These tough, leathery mushrooms were once thought to be nonpoisonous. However, recent research shows they’re often linked to fungal infections of the lungs. Symptoms can include breathing problems, prolonged cough, and other respiratory ailments.


#3. Funeral Bell / Deadly Skullcap

  • Galerina marginata

Types of poisonous mushrooms in Saskatchewan

  • The caps are usually pale yellow, brown, or orange, depending on age and weather, and are generally darker colored toward the center.
  • They have tan, fairly crowded gills and pale, thin flesh that darkens with age.

This aptly named toxic mushroom contains the same compounds as the famous Death Cap mushroom. These deadly compounds are known as amatoxins, and consuming them can result in SEVERE liver damage.

It is believed that about ten fatal poisonings in the last century can be attributed to the Funeral Bell.

This mushroom is often mistaken by foragers looking for edible or hallucinogenic mushroom species.

Foragers sometimes refer to these and other similar-looking mushrooms as LBMs or “little brown mushrooms” because they can be difficult to distinguish.

One of the identifying features of this poisonous mushroom in Saskatchewan is that it grows on decaying wood. Funeral Bells most frequently grow on conifer stumps and logs but are occasionally spotted in deciduous forests or even in open fields where woodchips have been dumped.


#4. Fly Agaric

  • Amanita muscaria

dangerous mushrooms

  • The caps are scarlet or dark orange with white, wart-like spots, which may wash off as mushrooms mature.
  • The stalk is white and brittle with shaggy rings of scales, a bulbous base, a cup-like veil near the base, and a skirt-like veil near the top.

The Fly Agaric is arguably the most iconic poisonous mushroom in Saskatchewan.

This colorful toadstool has an equally colorful history. The name “fly” may come from the mushroom’s historical use as an insecticide in parts of Europe. It contains ibotenic acid, which attracts and kills flies.

However, some people believe the name refers to the hallucinations that result from its consumption. This mushroom once saw widespread use in religious ceremonies.

Through the ages, this mushroom has also been wrapped up in fairytales and folklore. You may remember it as the mushroom Alice is given to eat in Alice in Wonderland or as the mushrooms in the Super Mario Bros games.

Fly Agarics grow in symbiotic associations with trees and can be found in delicious and coniferous forests in temperate and boreal regions.

While it is poisonous, deaths due to consuming Fly Agaric are rare.


#5. False Morel

  • Gyromitra esculenta

False Morel (Gyromitra esculenta)

  • The caps are brain-like, red-brown, wrinkled, and usually wider than tall.
  • They usually have more solid stems with small air pockets than true morels, which have hollow stems.

The False Morel is one of the more controversial poisonous mushrooms in Saskatchewan.

False Morels contain a compound called Gyromitrin, which the human body metabolizes into Monomethylhydrazine, a major component in rocket fuel.

This compound can damage the liver, central nervous system, and occasionally the kidneys. Victims may experience diarrhea, vomiting, dizziness, headache, and even death.

Given this horrible effect, it will probably surprise you to learn that part of its Latin name, esculenta, means edible!

In order to eat these funky-looking mushrooms, people use specific cooking techniques. These may include blanching the mushrooms outside or in a well-ventilated area, as Gyromitrin can become airborne during cooking.

Unfortunately, several instances of poisoning from False Morels, including fatalities, have occurred. It’s best to leave these to the experts! DO NOT TRY EATING THIS MUSHROOM.

False Morels usually grow in deciduous and coniferous forests in temperate regions. They often thrive in areas with sandy soil, and in coniferous forests, they are frequently found around pine trees.


#6. Poison Pie

  • Hebeloma crustuliniforme

Poison Pie (Hebeloma crustuliniforme)

  • The caps begin as convex but flatten with age and are off-white to pale, darker towards the center.
  • The stems are off-white with a slightly wider base, and the whole mushrooms have a firm, white inner flesh.

The name Poison Pie should be enough to keep any forager away from this toxic mushroom. But its other common name, Fairy Cakes, is a bit misleading!

Though less deadly than some species like the Death Cap (Amanita phalloides), Poison Pie is not a mushroom you want to snack on.

Consuming Poison Pie mushrooms can result in abdominal pain, vomiting, and diarrhea.

Thankfully, Poison Pies are rather unappealing anyway. They have strong radish-like aroma and bitter flavor.

Poison Pies have symbiotic relationships with various tree species. You may find them growing singly or in small groups in deciduous or coniferous forests.


#7. Saddle-shaped False Morel

  • Gyromitra Infula

Saddle-shaped False Morel (Gyromitra Infula)

  • Their surface may be smooth to somewhat bumpy and irregular, variable in color, and can be tan to yellowish brown, reddish brown, or dark brown.
  • The stems are roundish or slightly compressed and are usually white or pink-tinged with white mycelium near the base.

These toxic mushrooms get their name from their tell-tale, two-lobed saddle shape.

Though there are reports of people eating these mushrooms after boiling, most experts conclude Saddle-shaped False Morels are toxic. They contain contain the compound Gyromitrin.

Interestingly, the human body metabolizes Gyromitrin into Monomethylhydrazine, a significant component in rocket fuel.

Saddle-shaped False Morels usually grow in Saskatchewan in boreal, montane, or coastal forests. They often grow in close associations with several specific tree species, including Western White Pine, Black Spruce, Douglas Fir, Western Hemlock, Balsam Poplar, and Paper Birch.

You may spot Saddle-shaped False Morels growing singly or in small groups, often on rotten wood. It’s also commonly found growing on packed ground, like along rural roads or in campgrounds.
