High timber moisture
High timber moisture contents lead to decay. Above 30 % wet rot can develop and the optimum for this type of decay is 50-60%.
Dry rot can cause decay in timber at moisture cotents as low as 20% and the most rapid decay develops at 30-40%.

Dry rot fungus or Serpula Lacrymans
Dry rot fungus or Serpula Lacrymans is the most destructive fungus causing decay of timber in buildings. The mature fungus exhibits large fruiting bodies looking like mushrooms and these produce spores which are transmitted into the air initiating more dry rot .
The spores can lie dormant for years, springing to life under optimum growing conditions. Evidence of dry rot can be a mushroom, or visible white strands which will spread the fungus behind skirting boards and plaster to seek other wood hosts. Where sufficient spores accumulate they give the appearance of a fine orange dust. Diagnosis is a specialist job, and the surveyors at Johnson Ellis Ltd. are experts in rcognising dry rot. Swift treatment is vital to prevent the spread of dry rot.
