Some tiny mushrooms in the forrest

Mushrooms are a very nice and divers species, they grow in our forests and most of them only show a fraction of their size with their mushroom body outside of the ground. Of course the specimens here may only have a small compared to the biggest mushrooms, but the mushroom body we see outside of the ground is only a very small fraction of the size of myzel. Mushrooms (fungus) are the biggest living species on earth and can really grow huge. A lot of mushrooms live in symbiosis with trees and other plants but there are also parasites that slowly kill their feeder.

Using genotyping and clonal analysis, scientists determined that a 2500-year old specimen of Armillaria ostoyae in northern Michigan, United States originated from spores of a parent fungus in Ontario, Canada, then grew over millennia into the 21st century to a mass of 440 tons (4 x 105 kg), making it the equivalent in weight of 3 blue whales. By comparison of acreage, the Michigan A. ostoyae covers only 38% of the estimated land area of the Oregon "humongous fungus" at 3.5 square miles (9.1 km2),(2,240 acres (910 ha) which may weigh as much as 35,000 tons. It is currently the world's largest single living organism.
