What plant damage does each parasite fungus cause?

The parasitic fungus is a heterotrophic organism that lives on plants, mainly trees, and feeds on their organic matter. The damage caused by parasitic fungi can be divided into two categories. Firstly, this is the mechanical destruction of the tree, since the fungal hyphae literally penetrate the tree trunk, penetrating deeper and deeper into its structure. Secondly, the parasitic fungus draws its nutritious juices from the plant, and in nature everything is balanced, and the plant does not have enough nutrients to carry out its life support functions.
