Crop circles Crop circles Crop circles: Regardless of the true cause of the appearance Crop circles, those associated with the occurrence of fungi. This has already demonstrated by the 1792 by William Withering, when studying a particular type - of the approximately 60 total cycles to produce such-the Marasmius oreades. The rings of fungi tend to be extended from year to year from 10 to 30 cm. Believed that some circles in England are under way for 600 years, while in France have identified a cycle of this type of fungus, a region 800 meters and is over 700 years. The course remains a mystery why different species of fungi - more than 60 - are deployed in circular formations; For example the type of fungi commonly known as "alepopordes" - which are grown massively in Greece - can produce such formations. It is rather for another miracle of Nature. Generally there are 3 types Crop circles. - The first is essentially "invisible" once it leaves visible traces in the surrounding vegetation. Become apparent only when the fruit bodies appear as a circle of mushrooms. - The second occurs as an active growth of vegetation, a factor often higher and darker grass - The third produces a kind of destruction to vegetation, often leaving a fertile area between an "inner" and an "outer" ring. All, however, the ring fungi grow from a seed that grows less than the earth moving at a radius substantially the developing fibers. At some point the central piece of dried leaves in the region lives in a circle. The development of neighboring vegetation explained by scientists from the release of various fungi chemicals (enzymes) that act as fertilizer for the surrounding plants. Many times even the fibers of both fungi form a strong network of vegetation less than soil or water can penetrate. Thus a disc of dried grass, displaying a "dead area". Another reason for dry around the plants is the release of toxins from fungi. Sometimes they require many years of development of fungi to indicate cycles on earth, sometimes not complete circles, but generated large arrows or the Chamber or similar forms, really ... crop. Crop circles or colonies - mold? Many times science has come to explain unexplained phenomena of delivery. And well managed! Or will only see the effects?
