This research revealed that mushroom caps have a specialized outer skin that helps protect them from drying out. Like how human skin keeps our bodies from losing too much water, these fungal skins act as barriers that regulate water loss while still allowing some gas exchange. The effectiveness of this barrier changes based on humidity levels, helping mushrooms survive in varying environmental conditions. Impacts on everyday life: – Helps explain why mushrooms tend to appear after rain and in humid conditions – Provides insights for mushroom cultivation and storage – Contributes to understanding how fungi adapt to different environments – Could inspire new materials for moisture control – Helps explain mushroom preservation techniques
