THE DRY ROT FUNGUS

Dry rot 1Dry Rot 2

This fungus is unlike other fungi that occur in houses...... it is not found outside. Any area that gets wet and then dries out frequently is at risk, e.g. from leaking gutters, sinks, radiators and sometimes sub-floor areas with a lack of ventilation. Once the dry rot fungus takes hold, it can grow an average of an inch every six weeks. It can attack timber with a moisture content as low as about 20%, although it flourishes at about 25%.

The dry rot fungus (serpula lacrymans) is the wood destroying fungus par excellence, and outbreaks of this are more serious and harder to exterminate than any other fungus.

THE WET ROT FUNGUS

Wet rot

Wet rot is caused by several different fungi. Each one is quite different in character, but to the untrained eye they can easily be mistaken for the dry rot fungus.
