Agaricon (Laricifomes officinalis, Agarikon, Quinine conk) is a pathogenic wood-destroying fungus that grows in the Northern Hemisphere, mainly in the higher regions of Europe (e.g. Alps, Carpathians), Russia, Canada, Asia, etc. It mainly attacks larch and produces perennial fruiting bodies. which can be more than 60 cm long. They look like a hoof or a pillar. At first, they are yellowish white and soft, but with increasing age they darken (usually yellow-brown) and harden. The mushroom is not poisonous, but due to its consistency and taste, which is relatively bitter, it is not used in the kitchen, only as a means of traditional medicine. The English name is derived from the bitter taste, because people thought it contained quinine. Agaricon can be dried and crushed into powder, used pieces for decoctions and teas, etc. In traditional medicine it has been used for millennia, it was also found in a mummy 5,000 years old which was preserved in ice.
