Pando: Earth's biggest living thing?

 Pando, a grove of Populus tremuloides (Quaking Aspen) sharing one root system, from Fish Lake National Forest website

"The largest organism on Earth probably isn't a whale or a giant octopus or anything else you might naturally think of first. It's a tree — or a group of genetically identical trees that stretches across more than 100 acres of Utah's Fishlake National Forest."
