New data on freshwater lichens in Mediterranean streams

Abstract

New chorological data on freshwater lichens in central Spain are presented. We have identified twenty-one saxicolous species resistant to periodic immersion at five localities of Montes de Toledo. Eighteen species are reported for the first time in Castilla-La Mancha territory. Remarkable extensions in the distribution range are found for most lichen species highlighting the importance of intermittent streams for lichen diversity in the Mediterranean Region
