Some interesting records of Cladonia species from the Nizina Wielkopolska Lowland (W Poland)

Abstract

The lichen genus <em>Cladonia</em> comprises several similar species which have hardly been recognized in Western Poland so far. We used thin layer chromatography (TLC) as a simple technique to determine diagnostic lichen substances in morphologically similar <em>Cladonia</em> species. During field studies in Sandr Nowotomyski (western Nizina Wielkopolska Lowland), ten interesting records of <em>Cladonia</em> species were made. <em>Cladonia novochlorophaea</em> is reported for the first time from this region. Our records supplement the knowledge about the distribution of <em>Cladonia</em> species both in the investigated region and in Poland. All the records are compared with existing literature data from regional floristic inventories and distribution maps from Poland.
