Dry rot in ships from various countries. The second was launched in 1810 and, when inspected, the timbers of the upper decks were found to be infected with 'the dry rot'. By 1816 the cost of repairs for this vessel had exceeded the ship's original construction cost. Texts published in the 19th and early 20th centuries also used the term to describe fungi which produced substantial (white colored) mycelium including;"Antrodia (Fibroporia) vaillantii". Eventually, the term "dry rot" came to apply to only one or two fungi the main one being "Serpula lacrymans", in the majority of texts dealing with the subject, predominantly
Serpula lacrymans environments, the Himalayas, Northern California, the Czech Republic and east Asia. A recent study on the evolutionary origin and spread of this species using genetic markers (amplified fragment length polymorphisms, DNA sequences and microsatellites) on a worldwide sample of specimens suggested the existence of two main lineages, a nonaggressive lineage found in North America, and an aggressive lineage found on all continents, both in natural environments and buildings. "Serpula lacrymans" is considered to be the most damaging destroyer of indoor wood construction materials in temperate regions. In the United Kingdom alone, money spent by building owners rectifying damage caused by
