Dry rot treatment Many of these organisations support the environmental approach, for example Dr. Brian Ridout’s book "Timber Decay in Buildings, The Conservation Approach to Treatment" being jointly published by English Heritage and Historic Scotland. Historic Scotland’s "Technical Advice Note 24" advocates the use of environmental treatment of dry rot, as does advice on the Society for the Preservation of Ancient Building's website. Damp (structural) Dry rot treatment Dry rot treatment refers to techniques used to eliminate dry rot fungus and alleviate the damage done by the fungus to human-built wooden structures. Dry rot ("Serpula lacrymans") is considered difficult to remove, requiring drastic
Atromentic acid Atromentic acid Atromentic acid is a red-organge pigment found in fungi within the Boletales group. It is the precusor 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
