How do I get rid of Armillaria?
Cut out and burn diseased bark and roots, and paint cuts with a plastic paint. Leave the crown and roots permanently uncovered and do not replace soil during cultivation. This will halt the development of the disease, as exposure to air kills Armillaria. Remove and burn all badly affected trees, including roots.
What plants are affected by Armillaria root rot?
Armillaria root rot is a disease of trees and woody plants, although it also affects palms, succulents, ferns and other herbaceous plants. This disease is caused by fungi in the genus Armillaria, also known as “oak root fungus,” although the fungus has no specificity for oaks.
How do you identify Armillaria?
The genus Armillaria contains wood-rotting gilled mushrooms with white spore prints and gills that are attached to the stem or run down it. Most of the species have a partial veil, but the veil can manifest in several different forms—from cob-webby ring zones to full-blown rings.
What does Armillaria look like?
Clusters of honey-colored mushrooms may grow at the base of the tree in fall. Flat, white sheets of fungal growth can be found between the bark and the wood at the base of infected trees. Thick, black, shoestring-like, fungal strands sometimes grow in a net on infected trees and in the soil around the base of the tree.
What does mushroom rot look like?
When fresh they are tan to brown, fleshy, with gills beneath the cap, and lacking a ring (annulus) around the stem. While the presence of the characteristic mushrooms is a sure indicator of mushroom root rot, the lack of these fruiting bodies does not indicate the absence of disease.
What are the symptoms of Armillaria root rot?
Wilted, downward-hanging foliage is often the first obvious symptom of Armillaria root rot. Other symptoms include foliage yellowing, leaf drop, and dieback of upper limbs. During the rainy fall and winter, groups of short-lived mushrooms often grow around the base of Armillaria-infected trees.
Are there any honey mushroom look alikes?

What causes mushroom rot?
Mushroom Root Rot, caused by the fungus Armillaria tabescens (syn. Clitocybe tabescens and Armillariella tabescens), is a common and widespread disease affecting both conifers and hardwoods in Florida. This disease occurs statewide and has been reported on more than 200 species of trees and shrubs.
How is Armillaria spread?
Armillaria spreads by any activity that moves soil containing infested wood fragments, such as during cultivation. Most infections are thought to occur when a healthy root grows into or near an infested dead root piece and the fungus moves over.
