rhizomorph

a densely packed strand of fungal tissue, having the appearance of a root, which is produced by some higher fungi such as Armillaria. In some cases HYPHAE can be distinguished in the tissue. Rhizomorphs enable fungi to spread.

This conviction is reinforced also by the result of rhizomorphs macrostructure comparison: rhizomorphs of local ecomorphotypes (see table 1) and representants of A.
6 [micro]m thick), conspicuously clamped, smooth, of two types: 1) contents staining weakly in cotton blue, composing the cortical areas of rhizomorphs and all of the resupinate patches; and 2) contents staining strongly in cotton blue, limited to medullary portions of rhizomorphs.

It grows arms called rhizomorphs, which can extend 25 feet to 40 feet away from the root ball and even penetrate non-cellulosic material, such as plaster, concrete and brick and, after having penetrated that barrier, eat the wood on the other side," he said.
Adaptations to terrestrial habitats displayed by some homobasidiomycetes include rootlike rhizomorphs that allow the fungi to forage along the forest floor, drought-resistant sclerotia, and tough, perennial fruiting bodies.
This fungus lives in a below-ground habitat, spreading very slowly outward from tree to tree along roots or by growth through the soil using special shoestringlike structures called rhizomorphs," says Catherine Parks, a biologist with the Forest Service's research station in Portland.
Old tree stumps are a soft target, so remove these and treat the ground with Armillotox that is said to help reduce the spread of rhizomorphs.
Unlike most fungi that depend on moisture in the wood, Poria supplies it's own water through rootlike tubes called rhizomorphs, enabling it to move more quickly than other decay fungi.
With root rots, where there is a free spread of mycelium (Rosellinia sp), or rhizomorphs (Armillaria), an integrated approach with selective fungicides and biocontrol agents will be useful.
