Some of us did know that the largest organism in the planet belonged to one type of fungus: the Amillaria ostoyae. It's like us knowing life existed on Mars.

To date, a fungus of the same species was considered the largest living organism - it was found in the state of Washington and covered 1,500 acres of land. Recently though, a new organism was discovered and is now claiming rights to being the largest living organism.

The recently-discovered Amillaria was in the Malheur National Forest in the Blue Mountains of eastern Oregon! It's estimated to cover 2,200 acres and aged at least 2,400 years. Mario, this is one baby you might want to bring to Koopa...

How do they get so big? Scientists do believe that the dry state of Oregon could have spurred the large growth of these "Honey Mushrooms". Competing for land to grow on, these mushrooms sprout rhizomorphs, which are tough, stringy things that grow unchecked below ground. So the huge mushroom doesn't actually rise up, it digs even deeper.

Despite their name, though, the honey mushrooms aren't tasty. But yes, they are edible, and completely safe. Here's the salt, Mario. Bon appetit!
