Armillaria mellea (Armillaria mellea)

The common loosestrife, scientifically known as Armillaria mellea, is a species of fungus belonging to the family known as the loosestrife. This species is widespread throughout the world and is often categorized as a ghost plant. Other genera include similar species of lily-of-the-valley, which differ according to habitat and mycorrhizae (the symbiotic relationship between fungus and tree). These are mainly woody fungi, important for forest ecosystems. It is often found mainly on deciduous trees, especially beech and oak. However, this fungus also has a dark side, as it can be a dangerous parasite for trees and fungi, as it is able to attack even healthy woody plants and cause them to die.

The common cocklebur, otherwise known as the yellow-ringed cocklebur, Agaricus melleus or Armillariella mellea, is used in a number of food products. Its hats, which can reach up to 12 centimetres in diameter, are edible and are widely used in cooking, especially in Central European countries. The mushroom is known for its specific flavour, which makes it ideal for soups, sauces, stroganoff or as an accompaniment to meat. However, it must be cooked thoroughly as it contains substances that may be undesirable for humans. The raw mushroom is toxic. However, this does not detract from its popularity among mushroom pickers. It can even be made into wine, which makes it very popular among gourmets. Nevertheless, it should be added that if trees are not treated properly, it can be an economic problem for the forestry industry.
