Armillaria mushrooms beginning to decompose These mushrooms do not infect or damage the lawn in any way. It is best to remove them to limit the spread of spores that they release. If you choose to remove the mushrooms, please do so with gloved hands as they are poisonous. If left alone, the mushrooms decompose within a few days, leaving slimy masses. These too disappear rather quickly. There are no products that we can apply to your lawn to prevent or kill these mushrooms.
Armillaria mycelia (white color) under the bark of infected Ligustrum Armillaria is a fungus that often infects woody trees and shrubs. Oak and Hickory trees are often infected by this fungus, but so are many common woody ornamental plants. These include Ligustrum, Viburnum, Podocarpus, Azalea, and many more. This disease primarily infects the roots of susceptible plants. Visual symptoms of the disease include entire or partial decline or death of the plant. We can usually confirm infection by confirming fungal growth under the bark of the plant.
Often, people presume that the disease can be diminished by removing the mushrooms associated with Mushroom Root Rot. Unfortunately, doing so has no effect on the spread of the disease.
If Mushroom Root Rot is diagnosed in one of your shrubs or trees, it is best to remove the plant and dispose of it. There is no preventive or curative treatment for the disease. That said, removing and replacing soil prior to replanting may reduce the chances of infection of new plantings. In addition, some trees have been reported resistant to the disease - click here for more information from the University of Florida.
