Dry rot fungus

Dry rot fungus is a wood-eating and destroying fungus. It can affect the building’s integrity since it causes damage to wooden structures under favourable conditions for its growth. It thrives in small and poorly ventilated places, and where there are humidity and moisture. It is known for spreading through mortar joints, porous materials, cracks and dry wood.
