Most Common Types of Tree Fungus

Different types of fungi affect different parts of trees, so it’s important to know the most common types and how to identify them. 

Yellow Fungus

Yellow fungus is pretty easy to identify due to the bright yellow mushrooms and growth it produces. Interestingly enough, yellow fungus is harmless and edible for humans but can cause internal rot in trees. Careful pruning can remove yellow fungal growths and stop their spreading. 

Needle Blight

Needle blight attacks coniferous trees and causes their needles to turn a brownish-red color and die. Needle blight is not always deadly, but a sufficient infection can kill an entire tree. Fungicide for trees can stop and eliminate needle blight. 

Canker Disease

Canker disease attacks trees’ vascular systems and typically infects trees through open wounds. Canker disease fungi on trees usually presents as brownish-gray mottling near torn bark on trunks or branches. Preventing canker disease is a matter of tending to tree injuries before they get infected. 

Root Rot

Root rot attacks tree roots, preventing them from absorbing vital nutrients in the soil. The fungus grows in damp soil, so overwatering is a major cause of root rot. Root rot can cause tree leaves to prematurely turn yellow and cause canopies to thin out. The solution to root rot is removing infected roots before the tree starts to die. 


Mildew is a type of fungus that thrives in wet, moist environments. Mildew can infect trees and kill tree leaves before spreading to the branches and trunk. Most common types of mildew create whitish-gray powder spots on leaves. You can remove mildew using anti-fungal treatments or pruning the affected leaves. 

Stopping Fungal Infections in Trees

Most trees will encounter fungal spores in their lifetimes, but trees have immune systems that can fight back and protect them. As such, fungal infections are much more likely to occur in injured trees or trees that are already sick. 

So, the best method to preventing tree fungus growth is to ensure proper care and maintenance. This includes regular pruning, tree wound care, soil nutrient replenishment, and removing fungus from trees before it spreads. Healthy trees are much less susceptible to fungal infections and can properly fight back against harmful pathogens.
