![]() ![]() Sunscald – Sunscald most frequently occurs on young maple trees but can happen on older maple trees that have thin skin. While not technically a maple tree disease, there are several weather and environment related bark damages that can happen and may look like the tree has a disease. That being said, these growths do weaken the trunk of the tree and can make the tree more susceptible to falling during wind storms. Though often alarming to see, galls and burls will not harm a tree. These growths often look like large warts on the side of the maple tree and can get to massive sizes. It is not uncommon for maple trees to develop growths called galls or burls on their trunks. This fungus looks very similar to a maple tree root disease called collar rot, but with collar rot, the bark typically does not fall away from the base of the tree. Often, the center of the canker will bleed during the rising of spring sap.īleeding canker – This maple tree disease causes the bark to appear wet and is often accompanied by some bark coming away from the maple tree trunk, especially lower down on the trunk of the tree.īasal canker – This maple fungus attacks the base of the tree and rots away the bark and wood beneath. As the tree grows, the canker will continue to grow. It only affects bark that has been damaged by other issues or maple diseases.Ĭryptosporiopsis canker – The cankers from this fungus will affect young trees and starts out as a small elongated canker that looks as though someone pushed some of the bark into the tree. Steganosporium canker – This maple tree bark disease will create a brittle, black layer over the bark of the tree. The cankers of this fungus will look like small shallow depressions on the bark with warts in the center of each and will be white or grey. Valsa canker – This disease of maple trunks will normally affect only young trees or small branches. Also, if the bark is removed from the canker, there will be a layer of visible, light brown mushroom tissue. Over time, the maple tree will develop a canker that looks like a stack of paper that has been split and peeled back.Įutypella canker – The cankers of this maple tree fungus looks similar to Nectria galligena canker but the layers on the canker will normally be thicker and will not peel away from the tree trunk easily. In the spring, the maple tree will regrow a slightly thicker layer of bark over the fungus infected area and then, the following dormant season, the fungus will once again kill back the bark. Nectria galligena canker – This maple bark disease will attack the tree while it is dormant and will kill healthy bark. Occasionally, this fungus will also appear as red balls on the bark of the maple tree. These cankers can become slimy after rain or dew. Nectria cinnabarina canker – This maple tree disease can be identified by its pink and black cankers on the bark and typically affects parts of the trunk that were weak or dead. They all have the same thing in common, which is that they will create lesions (also called cankers) in the bark but these lesions will look different depending on the canker fungus that is affecting the maple bark. These fungus are the most common maple bark diseases. Several different kinds of fungi will cause cankers on a maple tree. Maple Tree Bark Diseases and Damage Canker Fungus Maple Tree Bark Disease Below you will find a list of diseases that affect maple trunk and bark. This is because bark diseases of maple trees are very visible to a tree’s owner and can often bring about dramatic changes to the tree.
