Wood decay caused by Serpula lacrymans (called true dry rot, a type of brown-rot). Fomes fomentarius is a stem decay plant pathogen Dry rot and water damage. A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot.
Blue stain fungi (also known as sap stain fungi) is a vague term including various fungi that cause dark staining in sapwood. [1] The staining is most often blue, but could also be grey or black. Because the grouping is based solely on symptomatics, it is not a monophyletic grouping.
Weeping Higan Cherry trees are rather prone to problems, particularly in dry soil. A type of bacterium can cause leaf spots and twig cankers. Small, reddish spots dry and drop out. A fungus can cause reddish spots which drop out leaving shot holes. Once the holes appear the leaves may fall from the tree and the disease is worse in wet weather.
Grosmannia clavigera is a species of sac fungus that causes blue stain in wood. It spreads to lodgepole pine, ponderosa pine, Douglas-fir, and whitebark pine trees from the body and a special structure in the heads of mountain pine beetles.
The tiny insect larva is attacking black locust trees.
The mycophagous phase of the life cycle takes place in dead or dying wood, where the nematodes live and feed upon fungi, rather than the wood itself. The nematode cannot travel outside of the wood independently; it must be transported by an insect vector. B. xylophilus has the shortest life cycle of any known parasitic nematode. In laboratory ...
The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
Wood-boring insects can degrade the wood aesthetically by boring holes, and also indirectly as vectors for fungi and nematodes which can cause structural damage. [ 5 ] Allison et al. [ 11 ] extrapolated information from one mill in southern British Columbia to suggest that wood-boring insects could cause an annual loss of US$43.6 million per ...
