G. clavigera has evolved a symbiosis with mountain pine beetles. The mountain pine beetle has evolved a specialized structure in its head, known as the mycangium, that carries spores of symbiotic fungi, such as G. clavigera, with them as they colonize new trees. The adult beetles bore into trees forming complex structures, known as galleries, to lay their eggs into. Through their tunneling the beetles distribute these microbes which become active and infect the tree. As G. clavigera proliferates through the tubules of the tree it stuffs them up preventing the flow of sap, terpenoids, and any other tree defenses to the outer layer of the living wood, where the beetles are living, thus protecting them.

Grosmannia clavigera is one of the species of fungus that causes blue staining in wood, which is often actually gray or black. This coloration is the result of the fungi melanizing as it spreads.

Mutualism with The Mountain Pine Beetle

G. clavigera has evolved a symbiosis with mountain pine beetles. The mountain pine beetle has evolved a specialized structure in its head, known as the mycangium, that carries spores of symbiotic fungi, such as G. clavigera, with them as they colonize new trees. The adult beetles bore into trees forming complex structures, known as galleries, to lay their eggs into. Through their tunneling the beetles distribute these microbes which become active and infect the tree. As G. clavigera proliferates through the tubules of the tree it stuffs them up preventing the flow of sap, terpenoids, and any other tree defenses to the outer layer of the living wood, where the beetles are living, thus protecting them.

Parasitism of Pine Trees

Grosmannia clavigera is one of the species of fungus that causes blue staining in wood, which is often actually gray or black. This coloration is the result of the fungi melanizing as it spreads. As the fungus spreads throughout the wood they continue to stop up the trees tubules, preventing the flow of water, sugars, and other nutrients throughout the tree resulting in the eventual death of the tree. G. clavigera feeds off of the trees resources during this process, it has even evolved the specialized ability to feed on the terpenoids the trees produce for defense and other purposes.
