Have you ever seen those dark, lumpy mushrooms growing on birch trees and wondered what they were? When foraging for edible mushrooms, it is essential to identify fungi correctly. Chaga mushrooms ( Inonotus obliquus ) are medicinal mushrooms that are unique and can be easily mistaken for other species.
Knowing how to identify these parasitic fungi is critical, as they are not only delicious but also medicinal. In this post, we will teach you how to identify Chaga mushrooms so that you can safely enjoy them!
What Trees Does Chaga Grow On?
Chaga typically grows on birch trees in cold climates, but can also be found on beech, alder, poplar, and willow trees. The fungus usually affects trees at least 20 years old and starts to grow gradually, appearing as a small black lump.
Over time, the Chaga continues to grow larger and becomes increasingly cracked and cork-like in appearance. While it is not harmful to the tree itself, Chaga can eventually kill the tree if left unchecked.
In contrast to its black exterior, the inside of Chaga is a bright orange or red color. This is due to the high concentration of carotenoids known to have antioxidant properties. For this reason, it has been used for centuries in traditional medicine for its purported health benefits.

Chaga vs. Tree Burls: A Misconception
A tree burl is an outward growth that develops on a tree and is typically brought on by some form of environmental stress. Burls are not fungi, whereas Chaga is.
Although the color of burls might vary depending on the species, they are often covered in the tree’s bark and are the same color as (or slightly darker than) the color of the tree.
Tree burls can be found on many kinds of trees, but they are most commonly seen on maples, oaks, elms, and birches. On the other hand, Chaga is a fungus that grows on birch trees. It is often referred to as a “black diamond” or “black mass” due to its dark color and complex, lumpy texture.
While tree burls can be harvested for wood, Chaga is often used for its medicinal properties. It is essential to distinguish between these two things before consuming or harvesting them.
How To Identify Chaga Mushroom
There are several ways of Chaga mushroom identification.
- While it can be found on other trees, it is most commonly found on paper, cherry, and yellow birch trees.; they are most often found on the trunk or branches of these trees. Primarily found in locations such as northern Europe, Siberia, Alaska, and parts of Canada.
- These mushrooms can also grow on less frequent host trees such as maple, black alder, grey alder, European ash, oak, and American elm trees.
- These mushrooms can be identified by their unique growth pattern
- Another way to identify Chaga mushrooms is by their appearance; as mentioned earlier, they have a dark brown or black exterior with a yellow-orange interior.
- Touch the mushroom; it should be hard, not spongy.
- Smell the mushroom; it should have a faint, earthy scent.

Harvesting Chaga Mushroom
In autumn, the birch trees enter a period of dormancy when the sap begins to withdraw back into the trunk and roots in preparation for winter. This is the perfect time to harvest Chaga, the nutrient-rich fungus for harvesters.
When temperatures drop below 5 C (41 F), it undergoes a chemical transformation that makes it especially rich in compounds like beta-glucans and melanin. Some harvesters believe that the fungus is at its best when temperatures dip even lower, around -20 C (-4 F).
Regardless of when you choose to harvest, it’s important to be conservative and leave at least 25% of the mushroom on the tree. Not only is this good for the tree’s health, but it also ensures that there will be plenty of Chaga left for future harvests. If you find a mushroom that meets all of these criteria, it is likely a Chaga mushroom.

Frequently Asked Questions (FAQs)
Can You Use Chaga From A Dead Tree?
While it is technically possible to use Chaga mushrooms taken from a dead or downed tree, it is not recommended. The canker the mushroom grows on is only fertile and alive when the tree is still alive. When the birch tree dies, the Chaga mushroom will also perish. Finding fruiting mushroom bodies on a dead tree is possible, but these are not as potent as those taken from a live tree.
If you’re looking to reap the many benefits of Chaga mushrooms, your best bet is to harvest them from a live birch tree. Not only will you be guaranteed a more potent product, but you’ll also be helping to support the health of our forests.
Can You Drink Too Much Chaga?
Chaga tea is high in oxalates, compounds that bind to calcium during digestion and are excreted in the feces. While most people can safely consume moderate amounts of Chaga tea, those with kidney problems or a history of kidney stones may want to avoid drinking too much of it.
Too much oxalate can lead to the formation of kidney stones, so it’s essential to stay hydrated when consuming Chaga tea. If you’re concerned about drinking too much Chaga tea, talk to your doctor or a registered dietitian.
