Wood decay fungi thrive in environments where the moisture content of the wood is sustained at 28% or higher. This high moisture level is essential for their growth and reproduction, as it allows them to break down the cellulose and lignin in the wood, leading to structural damage. These fungi are typically found in environments like decaying logs, post, and damp conditions, often leading to significant issues in wooden structures if left unchecked.

Non-decay fungi generally do not have the same moisture requirements as wood decay fungi. They may grow in dryer conditions and do not specifically contribute to the degradation of wood. Pathogenic fungi often require different conditions, focusing on living plants rather than dead organic matter. Mycorrhizal fungi form symbiotic relationships with plant roots, aiding in nutrient absorption and not specifically linked to high moisture content necessary for decay.
