Rediscovery of the epiphytic moss Ulota coarctata (Orthotrichaceae) in Poland

Abstract

. Ulota coarctata (P. Beauv.) Hammar was recently collected in Poland after more than half a century. This epiphytic moss was found at four localities in the Pojezierze Lubuskie lakeland in the western part of the country. Its diagnostic features are briefly presented, its habitat requirements are considered, the historical and recent findings of the species in Poland are dis - cussed, and its distribution is mapped. It is suggested that the species status should be changed from ʻendangeredʼ to ʻcritically endangeredʼ on the red list of mosses in Poland. Cieszyn
