20 Types of Mushrooms That Grow On Trees

20 Types of Mushrooms That Grow On Trees

Most mushrooms grow in damp, humid, and shaded places. Their growth in one’s garden or backyard is usually a sign of healthy soil. 

But have you ever spotted a mushroom growing on your tree? 

While it’s a cute idea, having mushrooms that grow on trees indicates that your tree is most likely damaged from the inside.

Mushrooms that grow on trees (or fungi) feed on the tree’s nutrients and spreads, releasing enzymes that cause the decomposition of the tree. 

Common types of mushrooms that grow on trees are shelf fungus, cap fungus, jelly fungus, white rot bark fungus, and brown rot bark fungus. 

What kinds of mushrooms grow on trees?

By properly knowing what kind of mushroom there is, it will be easier to diagnose how it affects the tree. 

It is also important to properly identify mushrooms before you touch, eat or do anything with them. 

Here, we’ve listed 20 types of mushrooms that grow on trees to look out for.

1. Chicken of the Woods

Scientific NameLaetiporus sulphureus
Common NameChicken of the woods, Crab of the woods, Sulphur polypore, Sulphur shelf, Chicken mushroom
Where they commonly thriveBeech, Oak, Chesnut treesDeciduous and conifer treesNorth America and Europe

The Chicken of the Woods is a wavy-edged shelf fungus mushroom native to the trees of North America and Europe. 

Its common name came from the fact that Laetiporus sulphureus tastes like chicken when cooked. It is best used for cooking when young and moist. 

Unfortunately, it is parasitic as it causes the decaying of the part of the tree on which it grows. 

The Chicken of the Woods is easy to identify because of its yellow or orange color, growing in fan-shaped layers around the tree. 

2. Hen of the Wood

Frequently Asked Questions

Why do mushrooms grow on trees?

Mushrooms grow on trees because of sub-optimal soil conditions and physical damage. 
When the soil becomes too dry or too wet, it causes damage to its roots. This in turn gives fungi an opportunity to enter the roots and absorb nutrients. 
On the other hand, cuts, scrapes, or other wounds of a tree provide another opportunity for fungi to penetrate its interior. 
Once open, the spores of the fungi can easily attach, thrive, and compete with the absorption of nutrients within the tree. 

Are mushrooms harmful to trees? 

Mushroom fungus spreads inside the tree and feeds on the hosts’ organic matter, signalling internal damage and causing  the tree itself to decompose. 
As a result, the internal damage spreads to the exterior of the tree and even causes its branches to break off. 

Are mushrooms on trees edible?

Some mushrooms that grow on trees are edible. 
Most are sought-after ingredients in the dishes that we know today such as the Chicken of the Woods, Hen of the Woods, shiitake, and blue oyster mushrooms.

What to do about mushrooms on trees? 

The best way to deal with mushrooms on trees is to leave them as they are. 
Removing the attached mushrooms can only cause the spread of its spores to the neighboring trees.
