Barrier properties of fungal fruit body skins, pileipelles, contribute to protection against water loss

Abstract The permeability of intact fungal fruit body skins (pileipelles) with respect to water and oxygen was determined for the first time. Methods that have been successfully applied to plant surfaces were used to study isolated pileipelles. Mechanically isolated skins from five genera of Basidio...

Methods that have been successfully applied to plant surfaces were used to study isolated pileipelles.

The skins reduced water loss by factors of 10 to 30, with permeability ranging from 2.8 to 9.8 × 10−4 ms−1. Oxygen permeability was much lower and ranged from 0.8 to 6.0 × 10−6 ms−1.
