Abstract The initial stages of Umbilicaria aprina Nyl. hydration (starting from the hydration level Δ m / m 0 = 0.048 ± 0.004) were observed using hydration kinetics, sorption isotherm and proton NMR. The thalli were hydrated from gaseous phase. The total saturation hydration level obtained at the r...
