Dry rot A common kind of fungal wood rot

Dry rot is wood decay caused by certain species of fungi that digest parts of the wood which give the wood strength and stiffness. It was previously used to describe any decay of cured wood in ships and buildings by a fungus which resulted in a darkly colored deteriorated and cracked condition.

<i>Serpula lacrymans</i> species of fungus

Serpula lacrymans is one of the fungi that cause damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. The Serpula lacrymans has the ability to rapidly colonise sites through unique and highly specialised mycelium which also leads to greater degradation rates of wood cellulose.

Wood-decay fungus

A wood-decay 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, are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation. Fungi that not only grow on wood but permeate its fibrous structure and actually cause decay, are called lignicolous fungi. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil. Various lignicolous fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.

Mycelial cord

Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs.

<i>Zygaena fausta</i> Species of moth

Zygaena fausta is a member of the family Zygaenidae, the day-flying burnet moths. Its bright aposematic colours of red, white and black on the wings indicate to possible predators such as birds that it is foul tasting or poisonous. In flight, the bright red abdomen is revealed, contrasting with the white legs and black head and antennae; the thorax is black and white with an eye spot on each side. There appears to be a considerable variation in pattern among specimens from different parts of Europe.

Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found on all continents except for Antarctica. Recent molecular work demonstrates that S. himantioides is a species complex including multiple cryptic lineages.

Xerocomic acid

Xerocomic acid is a red-orange pigment found in fungi of the order Boletales. It is the precursor to variegatic acid, and is preceded by atromentic acid and atromentin.. As an example, it is isolated from Serpula lacrymans. It is soluble in methanol. An oxidase acting on xerocomic acid is responsible for the "bluing" reaction seen in mushrooms.

Atromentic acid

Atromentic acid is a red-organge pigment found in fungi within the Boletales group. It is the precursor to variegatic acid and xerocomic acid, and is preceded by atromentin. As an example, it is isolated from Serpula lacrymans. It is soluble in methanol. Variants include homoatromentic acid. This pigment has been studied and elucidated by Wolfgang Steglich and colleagues over decades. When atromentin is oxidised with hydrogen peroxide a yellow product is produced. A sodium hydroxide solution is also yellow, but when this is neutralized with acid the red atromentic acid crystallises. Concentrated potassium hydroxide breaks up the compound to p-hydroxyphenylacetic acid and oxalic acid.

Isoxerocomic acid

Isoxerocomic acid is a red-orange pigment found in Boletales. It is the precursor to variegatic acid, and is preceded by atromentic acid and atromentin. As an example, it is isolated from Serpula lacrymans. It is soluble in methanol. It is the isomer of xerocomic acid and precursor to xerocomorubin.
