Extract from Wikipedia article: Armillaria gallica (synonymous with A. bulbosa and A. lutea) is a species of honey mushroom in the family Physalacriaceae of the order Agaricales. The species is a common and ecologically important wood-decay fungus that can live as a saprobe, or as an opportunistic parasite in weakened tree hosts to cause root or butt rot. It is found in temperate regions of Asia, North America, and Europe. The species forms fruit bodies singly or in groups in soil or rotting wood. The fungus has been inadvertently introduced to South Africa. Armillaria gallica has had a confusing taxonomy, due in part to historical difficulties encountered in distinguishing between similar Armillaria species. The fungus received international attention in the early 1990s when an individual colony living in a Michigan forest was reported to cover an area of 15 hectares (37 acres), weigh at least 9,500 kilograms (21,000 lb), and be 1,500 years old. This individual is popularly known as the "humungous fungus", and is a tourist attraction and inspiration for an annual mushroom-themed festival in Crystal Falls. Recent studies have revised the fungus's age to 2,500 years and its size to about 440 tons, four times the original estimate.
Armillaria gallica is a species of honey mushroom that grows in clusters, typically found in deciduous and mixed forests. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been reported to fruit from July to October, often in association with trees such as oak, birch, and pine. The fungus is characterized by its golden-brown cap, white gills, and ring on the stem. It is considered edible and has been found in various habitats, including urban parks and forests, in the region.
