Armillaria gallica is a species of honey mushroom in the family Physalacriaceae of the order Agaricales. It 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. 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, weigh at least 95 tonnes, and be 1,500 years old.
About Armillaria gallica in brief
Armillaria gallica 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 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, weigh at least 95 tonnes, and be 1,500 years old. It has been the subject of considerable scientific research due to its importance as a plant pathogen, its ability to bioluminesce, and its unusual life cycle. It produces fruit bodies that are up to about 10 cm in diameter, yellow-brown, and covered with small scales. On the underside of the caps are gills that are white to creamy or pale orange. The stem may be up to 10 cm long, with a white cobwebby ring that divides the color of the stem into pale orange to brown above, and lighter-colored below. The type species, Armillaria mellea, was until the 1970s believed to be a pleiomorphic species with a wide distribution, variable pathogenicity, and one of the broadest host ranges known for the fungi.
Because several research groups had worked with this widely distributed species, it was assigned several different names. In 1973, the species that Korhonen called EBS B was named A. bulbosa by Helga Marxmüller in 1982, as it was thought to be equivalent to Armillarias bulbosa var. bulbosa, first described by Jean Baptiste Barla in 1887, and later raised to status by Josef Velenovský in 1927. In 1987, the name EBS gallica was misapplied to A. bulbosa by Henri Romagnesi and renamed A pipes Eillaria Vulle-Vogte-Sauge-Vicomte in France. It was later determined to be the same species as the EBS of EBSB; EBSB was later renamed to A pipes gallica E. A. gallica A.
