"Stereum sanguinolentum" forms territorial clones while spreading by vegetative growths between spatially separated resource units; Armillaria spp, Heterobasidion annosum, Phellinus weirii, Inonotus tomentosus, and Phellinus noxius all work with Stereum sanguinolentum to attack the host.The combinations of these pathogens work together to form territorial clones that can cover up to several hectares and survive for hundreds of years while infecting trees.
