Pyramidula tetragona (Brid.) Brid. rediscovered in Fennoscandia and new to Norway

Abstract

The threatened moss Pyramidula tetragona is rediscovered in Fennoscandia and found for the first time in Norway. The species has recently been classified as regionally extinct both in Sweden and Finland, and it is thus highly surprising that we can present four new localities from southeast Norway. All localities are or have been influenced by agriculture through grazing or cereal crop production.
