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 . 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.
Huon pine is so rot resistant that fallen trees from many years ago are still commercially valuable. Merbau is still a popular decking timber and has a long life in above ground applications, but it is logged in an unsustainable manner and is too hard and brittle for general use. Ironbark is a good choice where available.
Its rot-resistant character also makes it an ideal wood for constructing the well-known houseboats of Srinagar, Kashmir. In Pakistan and India, during the British colonial period, deodar wood was used extensively for construction of barracks, public buildings, bridges, canals and railway cars. [ 24 ]
Dry rot is spread by spores which are present in most buildings. The minimum moisture content of timber for spore germination is 28–30% (lower than other rots), and the relative humidity must be in excess of 95%. Spores are resistant to desiccation and may still be viable for germination when they are several years old. [2]
The perpetual saturation of wood with water also inhibits dry rot, as does perpetual dryness. [9] Dry rot would appear to be a paradoxical term seemingly indicating decay of a substance by a fungus without the presence of water. However, its historical usage dates back to the distinction between decay of cured wood in construction, i.e. dry ...
Rot-proof or rot resistant is a condition of preservation or protection, by a process or treatment of materials used in industrial manufacturing or production to prevent biodegradation and chemical decomposition. Decomposition is a factor in which organic matter breaks down over time. It is commonly caused by fungus, mold or mildew.
Chamaecyparis lawsoniana, known as Port Orford cedar [2] or Lawson's cypress, [3] is a species of conifer in the genus Chamaecyparis, family Cupressaceae. It is native to Oregon and northwestern California , and grows from sea level up to 1,500 metres (4,900 ft) in the valleys of the Klamath Mountains , often along streams.
Cedar is part of the English common name of many trees and other plants, particularly those of the genus Cedrus. Some botanical authorities consider the Old-World Cedrus the only "true cedars" . [ 1 ] [ 2 ] Many other species worldwide with similarly aromatic wood, including several species of genera Calocedrus , Thuja , and Chamaecyparis in ...
