Presence of water: 80–90% of the mass of the fungi is water, and the fungi require excess water for absorption due to the evaporation of internally retained water. [ 7 ] Presence of oxygen : Very few saprotrophic organisms can endure anaerobic conditions as evidenced by their growth above media such as water or soil.
