Armillaria mellea
Armillaria mellea, commonly known as the honey fungus, is a basidiomycete fungus in the genus Armillaria. It is a plant pathogen and part of a cryptic species complex of closely related and morphologically similar species.
Description[edit | edit source]
Armillaria mellea is characterized by its yellow-brown cap, which can reach up to 15 cm (6 in) in diameter. The stipe is typically 8–20 cm (3–8 in) long and has a distinctive ring. The spores are white and non-amyloid.
Distribution and habitat[edit | edit source]
The honey fungus is widely distributed in North America and Europe, where it grows in forests and gardens. It is a saprophytic species that decomposes dead wood but can also act as a parasite, causing root rot in various plants.
Pathogenicity[edit | edit source]
Armillaria mellea is a notorious plant pathogen, causing Armillaria root rot in many species of trees and shrubs. The fungus spreads through rhizomorphs, which are root-like structures that can extend several meters in the soil.
Edibility[edit | edit source]
Despite its pathogenicity, Armillaria mellea is edible and is collected in many parts of Europe. However, it should be thoroughly cooked before consumption to neutralize potential toxins.
