Abstract
New localities of <em>Rhizocarpon distinctum, R. geographicum</em> and <em>R. reductum</em> are reported from NE Poland. <em>Rhizocarpon distinctum, R. grande, R. hochstetteri, R. lavatum, R. petraeum, R. polycarpum</em> and R. reductum</em> are reported from NW Belarus for the first time. <em>Rhizocarpon hochstetteri, R. lavatum</em> and <em>R. polycarpum</em> are new to Belarus. A key to species occurring in the area is given.
Highlights
Rhizocarpon Ramond ex DC. is a large genus of ca 200 species belonging to the family Rhizocarpaceae
A comprehensive taxonomic study of yellow species of Rhizocarpon in Europe was conducted by Runemark (1956a, b), but intra-specific variation of the R. geographicum complex is still
The knowledge of the species diversity of Rhizocarpon in north-eastern Poland is relatively good as reflected in literature data (e.g., Zielińska 1980; Fałtynowicz 1994; Bystrek, Kolanko 2000; Kukwa, Fałtynowicz 2002; Cieśliński 2003; Sparrius 2003; Zalewska et al 2004a, b; Kolanko 2005; Kubiak 2005; Matwiejuk 2008), while it is insufficient in Belarus
Summary
Rhizocarpon Ramond ex DC. is a large genus of ca 200 species belonging to the family Rhizocarpaceae. Species of the genus grow on rock and are long living They have been widely used in studies on moraine dating in a procedure known as lichenometry. The knowledge of the species diversity of Rhizocarpon in north-eastern Poland is relatively good as reflected in literature data (e.g., Zielińska 1980; Fałtynowicz 1994; Bystrek, Kolanko 2000; Kukwa, Fałtynowicz 2002; Cieśliński 2003; Sparrius 2003; Zalewska et al 2004a, b; Kolanko 2005; Kubiak 2005; Matwiejuk 2008), while it is insufficient in Belarus. Species of Rhizocarpon grow on erratics and stones in the area investigated Those are postglacial boulders brought to the area by the Scandinavian ice-sheet in the Pleistocene. Fortifications dating from World War I in NW Belarus in the vicinity of Grodno are currently being investigated by historians and by biologists
