The humongous fungus

Armillaria gallica is a root-pathogen of forest trees that spreads by rhizomorphs

Smith et al. collected Armillaria cultures using wooden baits, as well as tissue and spore cultures from fruiting bodies

Using RFLP and RAPD (random amplified polymorphic DNA) analyses, they showed that individual clones of Armillaria can be very extensive

The largest occupied 15 hectares, with a mass of 10,000 kg, and age of 1500 years.
