why do the mushrooms you reblogged grow in a circle? ;o
Those are best known as fairy rings. Mushrooms are actually the fruiting bodies of a much larger underground organism, an underground network called mycelium.
The purpose of the mushrooms is to release spores (seeds), which will drift away in the wind and land on some dead plant material somewhere and a new colony of fungi gets its start. The first batch of mushrooms will be clustered in a tight, compact spot, not a ‘fairy ring.’ But eventually the fungi will run out of food, which means the mycelium has to constantly expand to find new nutrients.
If all directions have a roughly equal distribution of nutrients the fungus will probably spread out in a circular pattern. There will not be any mushrooms in the center of the ring because the food there has been exhausted.
You can just imagine that this fairy ring just keeps getting larger and larger and larger, and some of these ‘fairy rings’ are actually so huge they span hundreds of miles. Scientists are of the opinion that this is one organism, the largest and most ancient organism on Earth! Scientists say ‘forget all that rubbish about bristlecone pine trees being the oldest living things on the planet.’ Giant redwood trees are just youths if you compare them to the age of the one fungi organism that comprises these large fairy rings.
