Detailed explanation-1: -This group of fungi are commonly found on dead trees, branches, and stumps but rarely cause serious decay in living trees. They can cause heart rot on trees wounded by pruning or bark injury.
Detailed explanation-2: -Plant roots and fungi form symbiotic relationships. The fungi help trees or shrubs, and in return, the roots give the fungi carbon, carbohydrates, and other nutrients. The symbiotic relationship between fungi and plant roots is called a mycorrhiza. The specific fungi involved are called mychorrizal fungi.
Detailed explanation-3: -The tree fungus invades through the roots then spreads through the plant’s vascular system. Once the Xylem, the tree’s water transportation system, is infected it becomes clogged and water can no longer reach the tree’s leaves. Verticillium is common and affects several hundred species of trees and shrubs.
Detailed explanation-4: -Essentially, fungi grow by decaying their host and feeding on the organic matter contained inside the tree. Most grow during spring and fall on already decaying wood.
