13 Common Mushrooms Found in Alberta! (2025)
What kind of mushroom did I find in Alberta?
If you spend time outside, you’ve probably asked this question at least once. Mushrooms are incredibly common in Alberta, and they come in all shapes, sizes, and colors.
Believe it or not, there are THOUSANDS of different types of mushrooms that live in Alberta. Since it would be nearly impossible to write about them all, I focused on the most common types that are seen.
IMPORTANT: You should NEVER eat a mushroom you find. 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)!
13 COMMON MUSHROOMS in Alberta:
#1. Common Greenshield Lichen
- Flavoparmelia caperata
Identifying Characteristics:
- This lichen grows in roughly circular patterns with wavy edges.
- The coloring is pale green to yellowish.
Common Greenshield Lichen is technically not a mushroom, but instead, it is a lichen. Lichens are complex organisms made up of both fungi and algae. The combination of these two types of organisms allows lichens to live in diverse climates, ranging from cool, dry areas to warmer regions with humid weather.
As a result, you can find Common Greenshield Lichen across Alberta. It most often grows on tree bark, although you might occasionally find it on rocks. Look for a rounded, pale-green growth with wavy edges.
#2. Fly Agaric
- Amanita muscaria
Identifying Characteristics:
- Caps are 8–20 cm (3–8 in) in diameter.
- The stalks are 5–20 cm (2–8 in) tall.
- These mushrooms have the typical looks of a “toadstool” with a bright white stalk and red, white-spotted cap.
I think this is the CUTEST mushroom in Alberta! 🙂
Fly Agaric looks just like the mushrooms found in Mario video games.
These mushrooms are considered toadstools, which are usually poisonous to humans. Fly Agaric is no exception. This fungus can cause hallucinations, low blood pressure, nausea, loss of balance, and in rare cases, death. If you ingest it, you should seek medical treatment immediately.
Luckily, Fly Agaric is a very conspicuous fungus in its fully-grown form. However, young mushrooms can be mistaken for other edible types, so you should steer clear of eating any wild mushrooms.
#3. Splitgill Mushroom
- Schizophyllum commune
Identifying Characteristics:
- 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.
Splitgill Mushrooms in Alberta thrive 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.
Interestingly, this is one of the few mushrooms that grow abundantly in tropical weather. It thrives in heat and humidity thanks to its rubbery, tough structure. Fleshy, sponge-like mushrooms quickly rot, whereas this species lasts much longer.
Even though Splitgill Mushrooms are not poisonous, it’s best not to consume any you find in the wild. The unprocessed fungus can cause lung infections, and this mushroom can be confused with more dangerous species.
#4. Pear-shaped Puffball
- Apioperdon pyriforme
Identifying Characteristics:
- The cap portion is 1.5-4.5 cm (0.6-1.8 in) wide by 2-4.5 cm (0.8-1.8 in) tall.
- Their coloring is off-white with brown spots that are dense toward the middle of the cap and spread out at the edges.
- Most specimens are pear-shaped, but they are often spherical as well. They grow in clusters of 4-10 caps.
Look for these mushrooms in Alberta on rotting logs.
Pear-shaped Puffballs are commonly found during their long fruiting season, which lasts from July to November. They are nonpoisonous.
However, Pear-shaped Puffballs look similar to several dangerous species of poisonous mushrooms. For example, a lookalike called the Earthball mushroom can cause gastrointestinal distress, fever, and eye infections.
It’s better to purchase Pear-shaped Puffballs from an expert or forage with someone who knows what they’re doing. If not, you may end up sick.
#5. Shaggy Mane
- Coprinus comatus
Identifying Characteristics:
- The caps are 4–8 cm (1.6–3.1 in) wide and 6–20 cm (2.3–8 in) tall.
- Their coloring is white when they first emerge, slowly turning black as their scales lift.
- These mushrooms grow directly from the ground as single caps or clusters.
It’s easy to see how Shaggy Mane Mushrooms in Alberta got their name!
These tall, slender mushrooms have distinctive scales that make them look like they’re covered in shaggy hair. They often grow in suburban yards or fields straight from the ground.
Shaggy Manes definitely have some “yuck” factors. They’re called Ink Caps because their black gills liquefy and leak down the mushroom to release its spores. Additionally, the entire mushroom will “auto-decay,” digesting itself into a dark liquid within hours of being picked.
Shaggy Manes look very similar to poisonous mushrooms that are found in Alberta. Leave these mushrooms where you found them, and never eat them!
#6. Witch’s Butter
- Tremella mesenterica
Identifying Characteristics:
- Fruiting bodies can be up to 7.5 cm (3 in) in diameter.
- The shape is irregular, gelatinous, and brain-like.
- This fungus is typically bright lemon-yellow.
This is one of the WEIRDEST mushrooms in Alberta!
Witch’s Butter, which gets its name from its unusual shape and color, completely differs from what most people picture in a mushroom. It has an irregular, ridged appearance that looks like brains and a jelly-like texture that trembles and vibrates if disturbed. Additionally, its coloring is bright yellow, unlike most mushrooms that blend in with their environment.
If the appearance of Witch’s Butter wasn’t strange enough, it also has fascinating properties that set it apart. During dry weather, this fungus dries and shrivels into a leathery mass. Then, when it rains, it fully revives back into its original state!
Look for this strange fungus on dead tree limbs that are still attached to trees or recently fallen branches. It will grow on any deciduous tree but is most prevalent on red alder.
#7. Common Puffball
- Lycoperdon perlatum
Identifying Characteristics:
- Mature specimens are 1.5-6 cm (0.6 to 2.3 in) wide by 3-10 cm (1-4 in) tall.
- Their coloring is white to off-white, with spines and warts that are varying shades of brown.
- The shape varies from pear-shaped to spherical with a wide stalk.
It’s easy to find Common Puffball Mushrooms in Alberta.
These distinctive fungi grow in gardens, yards, roadsides, and forest clearings. They’re easy to find because of their large size and bright white coloring. Common Puffballs also have an unusual covering of spiky warts on their surface, setting them apart from other types of puffballs.
Even though these mushrooms are considered nonpoisonous, it’s important to use caution when handling wild mushrooms. You shouldn’t eat any mushroom that hasn’t been identified by an expert because of the risk of misidentification. For example, the Common Puffball can easily be confused with immature Amanita mushrooms, which are poisonous and sometimes even deadly.
In addition, spores contained in the Common Puffball’s warts are released with handling. These spores can cause severe lung inflammation, resulting in cough, wheezing, or trouble breathing. Dogs are particularly susceptible to this symptom, so be careful not to let your pet play near Common Puffballs.
#8. Orange Jelly Spot
- Dacrymyces chrysospermus
Identifying Characteristics:
- Complex groups of caps grow up to 6 cm (2.4 in) across.
- The coloring is vibrant orange-yellow.
- This fungus has an irregular, wavy shape and often looks like goop stuck to a tree.
Orange Jelly Spot isn’t technically a mushroom in Alberta!
Even though it looks like a mushroom, this species is just a fungus. As you can see, it gets its name from its unusual shape and color, which completely differs from what most people picture in a mushroom. In fact, it looks more like a bright orange brain than anything else! Orange Jelly Spot also has a jelly-like, wobbly texture.
You can find this strange fungus on dead conifer trees like pine and spruce. It was originally discovered in New England but has a worldwide distribution! Most people probably go their whole lives without knowing this oddity exists, but if you keep an eye out in the woods, you’re likely to find it.
#9. Artist’s Bracket
- Ganoderma applanatum
Identifying Characteristics:
- Caps can be 3–30 cm (1-12 in) wide × 5–50 cm (2-20 in) long and up to 10 cm (4 in) thick.
- New specimens are white but quickly turn a dark reddish-brown as they mature.
- Their shape is similar to a fan, and these mushrooms grow in a shelf-like formation individually or in groups.
This is one of the largest mushrooms in Alberta!
Artist’s Bracket caps are hard to miss, as they grow directly out of tree trunks and are too large to overlook. They’re tough and woody, and the surface of this mushroom often feels like leather.
Artist’s Bracket gets its name from a peculiar property of its white underside. You can scratch designs and pictures into their surface, and the picture remains as the mushroom dries. Here’s an example!
#10. Candleflame Lichen
- Candelaria concolor
Identifying Characteristics:
- Single lobes of this lichen are less than 1 cm (0.4 in) wide, but they can cover enormous surface areas, including entire trees.
- The coloring is golden yellow to yellow-green.
- This lichen has a branch-like appearance, similar in shape to coral.
Candleflame Lichen is technically NOT a mushroom in Alberta.
Instead, lichens are complex organisms that involve a symbiotic relationship between fungus and algae. The mutually beneficial relationship allows lichens to survive in habitats that would kill fungi and algae independently.
For example, Candleflame Lichen can be found anywhere from arid deserts to wet conifer forests. It’s one of the most widespread lichens in the world! Look for this lichen on trees, where it attaches to tree bark and slowly spreads.
#11. Elegant Sunburst Lichen
- Rusavskia elegans
- It forms small colonies up to 2.5 inches across.
- The body is leaf-like and divided into small lobes.
- The color may be yellowish-orange, bright orange, or dark reddish-orange.
Elegant Sunburst Lichen is more than just a beauty to look at!
This was the first species scientists used for lichenometry, or using a lichen’s presumed growth rate to estimate the age of exposed rock faces. Archeologists, paleontologists, and geologists, in particular, use this method to estimate how old the specimens they find might be.
Elegant Sunburst Lichen is widespread, growing on rocks in humid and dry climates. Pay special attention to rocks that birds or rodents perch on because their droppings provide the lichen with the extra nitrogen it needs to thrive.
Its color may vary depending on where you find it. Elegant Sunburst Lichen is often a lighter yellowish-orange when growing in creeks. On rocks that are out of the water, it tends to be bright orange; in dry areas, it may darken to reddish-orange.
#12. Hooded Sunburst Lichen
- Xanthomendoza fallax
- This lichen grows in small rosettes up to 1.5 inches (3.81 cm) wide.
- The rosettes are leaf-like, appear wrinkled, and are divided into branches.
- They’re usually yellowish-orange, reddish-orange, orange, or greenish-yellow.
The Hooded Sunburst Lichen is a common species in Alberta.
Its color varies somewhat with its habitat. In areas of deep shade, it’s often greenish-yellow, while in partial shade, it may be yellowish-orange to orangish-red, and in full sun, it can be deep orange.
This lichen thrives on the bark of hardwood trees, particularly elm or oak trees. However, it’s adaptable and grows on other hard surfaces, including cemetery stones, large rocks, or even bones.
Hooded Sunburst Lichen often reproduces asexually. The tips of the lichen’s lobe curl around to expose crescent-shaped slits that open and release packets of young lichen. These packets are then dispersed to colonize other surfaces.
#13. Black Knot
- Apiosporina morbosa
- This fungus forms rough black growths on the twigs or branches of trees in the Prunus genus, such as cherry, plum, apricot, and chokecherry.
You may have spotted this unusual fungus without realizing what it was.
Black Knot resembles a clod of dirt or droppings on a twig or limb. This fungus was first detected in Pennsylvania in 1821 and, after spreading across North America, was a significant problem in plum and cherry orchards in the late 19th century.
The fungus first shows as olive green in the spring and spreads spores to infect nearby trees as they mature. The spores infect trees at wounds or shoots. Black Knot usually occurs on twigs and smaller limbs. It can disfigure trees and affect young trees’ health and productivity by causing foliage to wilt and shoots to die. Occasionally, Black Knot forms on the main tree and can kill a tree when it girdles the main trunk or large limbs.
Fortunately, orchardists can effectively manage Black Knot today by pruning affected limbs.
