None at all

The correct answer is: Black mold and wood decay

Wood decaying fungi can lead to significant deterioration of wood material. This type of fungi feeds on the cellulose and lignin in the wood, breaking down its structural integrity, leading to wood decay. The decay can manifest as soft, spongy wood that can easily crumble or break apart, severely affecting the strength and stability of wooden structures. In addition to causing decay, certain types of wood decaying fungi can also produce black mold, which is a secondary issue that can arise in moist environments where wood is affected. The presence of black mold not only indicates wood deterioration but can also pose health risks to humans, as molds can produce allergens and irritants. This combination of wood decay and potential mold growth illustrates the destructive nature of wood decaying fungi, highlighting the need for effective management and prevention strategies in areas prone to moisture and fungal growth.
