Abstract

The Asian moss Didymodon constrictus (Mitt.) K.Saito is newly reported for North America from Alberta, Canada. The species features basally fragile flagellate branchlets, which when young are similar to bulbils. Following recent revisionary work, a combination in Geheebia Schimp. is provided and evolutionary relationships are discussed. Features of the habitat and geographic distribution are described. Most Asian specimens of D. constrictus examined for this study were actually D. icmadophilus (Schimp. ex Müll. Hal.) K.Saito.
