Patterns other than the basic ring or arc are also possible: circles, doubled arcs, sickle-shaped arcs, and other complicated formations are also formed by this process. After some time they are removed by biotic factors from the ground, at which stage a zone on the surface soil becomes visible. These zones are caused by the mycelia which, during a dry year, coat the roots of grasses and other herbs in meadows. One of the manifestations of fairy ring growth is a necrotic zone-an area in which grass or other plant life has withered or died. Necrotic or rapid growth zones įairy ring in a courtyard ( Trinity Great Court) If they make an arc or a ring, they continuously grow about the centre of this object. The second theory, which is presented in the investigations of Japanese scientists on the Tricholoma matsutake species, shows that fairy rings could be established by connecting neighbouring oval genets of these mushrooms. The underground presence of the fungus can also cause withering or varying colour or growth of the grass above. One states that the fairy ring is begun by a spore from the sporocarpus. There are two theories regarding the process involved in creating fairy rings. The mycelium moves outward from the center, and when the nutrients in the center are exhausted, the center dies, thereby forming a living ring, from which the fairy ring arises. This breaks down larger molecules in the soil into smaller molecules that are then absorbed through the walls of the hyphae near their growing tips. The mycelium of a fungus growing in the ground absorbs nutrients by secretion of enzymes from the tips of the hyphae (threads making up the mycelium).
