The paper presents a brief review of published so far and recently recorded unpublished bryological data concerning the distribution in Poland of two neophytic (sensu Meusel 1943) mosses: Campylopus introflexus (Hedw.) Brid. and Orthodontium lineare Schwaegr.to estimate their current influence on native bryoflora. The data clearly indicate the constant spreading of these species towards the east, however, there is no direct evidence that they have been limiting the occurrence of native moss species. They are acidophilous species, so the acidification of the environment probably promotes their expansion. Maps of the most current distribution of Campylopus introflexus and Orthodontium lineare in Poland (in a system of ATMOS-grid squares) are provided, as well as a description of the first locality in Poland of another European bryo-neophyte species Leptophascum leptophyllum Mull.
