New national and regional bryophyte records, 10

Abstract

The discovery of Paludella squarrosa (Hedw.) Brid., new to Ireland, is reported. This Boreo-arctic Montane species has a relic distribution in western and central Europe and was formerly more widespread. The reasons for its decline and its documented extinction from Britain and the Netherlands in recent times are discussed. The vegetation and ecology of the Irish locality are described. The associated species include Leiocolea rutheana, another Boreal relic species and a second record for Ireland.
