description Armillaria mellea Overview
Armillaria mellea, commonly known as the honey fungus, is a widely distributed basidiomycete mushroom found in the Northern Hemisphere. It is a facultative parasitic species capable of acting as a devastating forest pathogen. The fungus spreads through root systems and black, bootlace-like rhizomorphs, infecting and killing hundreds of tree and shrub species. While considered a destructive forestry pathogen, the fruiting bodies are edible when thoroughly cooked, though they can cause gastric distress if consumed raw.
