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.

Pulvinic acid Pulvinic acid Pulvinic acid is a natural chemical pigment found in some lichens. Dimers of pulvinic acid have been found in the fungi "Scleroderma citrinum" and "Chalciporus piperatus". Hydroxypulvinic acid pigments (pulvinic acid type family of pigments) have been found in "Boletus" (e.g. "Boletus erythropus"), "Boletinus", "Chalciporus", "Gyrodon", "Leccinum", "Pulveroboletus", "Suillus" (e.g. "Suillus luteus", "Suillus bovinus", and "Suillus grevillei"), "Paxillus" (e.g. "Paxillus involutus"), "Serpula" (e.g. "Serpula lacrymans"), "Xerocomus" (e.g. "Xerocomus chrysenteron"), "Hygrophoropsis" (e.g. "Hygrophoropsis aurantiaca"), "Retiboletus" (e.g. "Retiboletus nigerrimus"), "Pulveroboletus" (e.g. "Pulveroboletus auriflammeus"), and are generally characteristic of Boletales. Derivatives and similar pigments of this family include atromentic acid, xerocomic
