Dicranella staphylina is reported for Russia
basing on recent collections from Kaliningrad
and Moscow Provinces. The study of herbarium
specimens of Tortula truncata
and T. acaulon reveals however that Dicranella staphylina
was collected in Moscow Province in 1985 and in Kursk Province
in 1999, but remained an unrecognized admixture to collections of these
species. Description and differentiation from related and superficially similar
species, including Leptobryum pyriforme, are provided.
