A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as Armillaria (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal ...
Fomitopsis pinicola. Fomitopsis pinicola, is a stem decay fungus common on softwood and hardwood trees. [1] Its conk (fruit body) is known as the red-belted conk. The species is common throughout temperate Europe and Asia. [1] It is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems.
Laminated root rot. Laminated root rot also known as yellow ring rot is caused by the fungal pathogen Phellinus weirii. Laminated root rot is one of the most damaging root disease amongst conifers in northwestern America and true firs, Douglas fir, Mountain hemlock, and Western hemlock are highly susceptible to infection with P. weirii.
The white rot fungus found in the roots is the sign of telling whether the tree has been affected by H. annosum. The bark changes colors as the stages progress, they go from pale yellow, to a crusty light brown, and finally in its advanced stage it turns white with the signature of Fomes annosus―a sprinkled streak of black spots. Another sign ...
Heart rot. In trees, heart rot is a fungal disease that causes the decay of wood at the center of the trunk and branches. Fungi enter the tree through wounds in the bark and decay the heartwood. The diseased heartwood softens, making trees structurally weaker and prone to breakage. Heart rot is a major factor in the economics of logging and the ...
Dendroctonus pseudotsugae, the Douglas-fir beetle, is a species of bark beetle found in western North America. Three subspecies exist that correspond to the subspecies of Douglas-fir. The beetles also infest downed Larch trees. [1] Outbreaks often occur in conjunction with drought, root rot diseases, overcrowding, damage by insects that damage ...
Inonotus obliquus, commonly called chaga (/ ˈtʃɑːɡə /; a Latinisation of the Russian word чага), is a fungus in the family Hymenochaetaceae. It is parasitic on birch and other trees. The sterile conk is irregularly formed and resembles burnt charcoal. It is not the fruiting body of the fungus, but a sclerotium or mass of mycelium ...
A drawing on the lower side of the sporocarp of G. applanatum. A peculiarity of this fungus lies in its use as a drawing medium for artists. [13] When the fresh white pore surface is rubbed or scratched with a sharp implement, dark brown tissue under the pores is revealed, resulting in visible lines and shading that become permanent once the fungus is dried.
