The worst mushrooms that need to be removed from your tree as soon as identified are the following:

  1. Honey fungus

Honey fungus, also called Armillaria, settles first on the roots of a tree and is usually present during summers when the weather is warm and dry. When your tree is infected with this fungus, its branches will eventually die and will have wilted leaves. As the disease progresses, your tree will fall off on its own due to its weakened state. Armillaria quickly spreads on trees such as alder, beech, willow, and birch.

If honey fungus is present in your tree, remove the infected tree before it can make other trees sick as well. If it is allowed in your locality, opt to have your tree burned to effectively kill the spores.

  1. Ganoderma

Ganoderma is a fungus that mostly attacks deciduous trees such as oaks and maples. Sadly, when Ganoderma is already attached to your tree, there is nothing more you can do about it as it is considered a very lethal disease and will kill your tree in a few months or years. When your tree has this fungus, the best thing for you to do is to properly remove your tree to stop the spread of infection to other trees. Proper care and maintenance is the only way to protect your tree from Ganoderma.

When your tree has this fungus, its leaves will turn yellow and will wilt. Depending on the rate of spore growth, more branches will die and your heartwood will decay. This type of fungi prefers trees that are large in diameter with broad leaves such as maples, oaks, and sycamores.

  1. Kretzschmaria

Also called brittle cinder fungus, usually grows on your tree during the months of March to May. When your tree has injuries on its root base, the brittle cinder takes advantage and will work its way up to your tree, causing it to rot. This fungus is aggressive and will cause your tree to rot usually in just a couple of months.

Brittle cinders got their name as they turn black and will crumble during the late stages of summertime. When your tree has Kretzschmaria, it would be best to isolate them from other trees to prevent spreading the infection.
