An Unusual Epiphytic Habitat for Hedwigia ciliata (Bryophyta: Hedwigiaceae) in Poland (Central Europe)

摘要

In Poland, Hedwigia ciliata (Hedw.) P.Beauv., an obligatory epilithic moss species, has in recent years also been observed on the bark of trees.In this paper, we describe 25 recently identifed sites in which epiphytic H.ciliata has been observed, and provide a plausible explanation to account for this phenomenon.
