Abstract: 26 fig. 1 tab. ["The pore system within the thalli of 13 lichen taxa belonging to the family Umbilicariaceae has been studied by means of mercury intrusion porosimetry. A characteristic bimodal pore size distribution with a central depression around 0.05 µm of equivalent pore radius was obtained in all lichen samples. However, clear differences were found among the pore size distributions of each taxa." (sic)]
