Grimmia anomala Schimp., new to Britain and Ireland

Abstract

Grimmia anomala is reported from seven sites in Scotland and Ireland. Confusion in the past with Grimmia hartmanii has meant that this species has been overlooked. Its occurrence in Scandinavia and the Faroes means that its sites in Scotland are not unexpected but the Irish localities for this boreal-montane species are noteworthy.
