Genus Armillaria

One of my observations was a mushroom from the genus Armillaria. In environments with the correct amount of sunlight and water, Armillaria can live for hundreds of years. Armillaria species are found on the ground and the wood of trees and the hyphae of these species combine into rhizomorphs, which are the main organ responsible for secreting enzymes to digest and absorb food. One of the most well-known applications of armillaria is root rot caused by the species, Armillaria mellea. By using its filaments to attack tree roots, the parasitic fungus spreads up the tree and through the trunk until the tree dies. By autumn, yellow mushrooms begin to grow at the base of the trees and the fungus continues to invade and ravage surrounding trees.
