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

Abstract

The lichen genus Cladonia 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 Cladonia species. During field studies in Sandr Nowotomyski (western Nizina Wielkopolska Lowland), ten interesting records of Cladonia species were made. Cladonia novochlorophaea is reported for the first time from this region. Our records supplement the knowledge about the distribution of Cladonia 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.
