Stepping beyond the 700 milestone: four new mosses in the bryophyte flora of Montenegro

Four moss species were recorded during bryological studies for the first time in Montenegro in 2016 and 2017. Hookeria lucens (Hedw.) Sm., Plagiothecium undulatum (Hedw.) Schimp. and Sphagnum quinquefarium (Braithw.) Warnst. were found on Hajla Mt, while Nyholmiella gymnostoma (Bruch ex Brid.) Holmen & Warncke was found on Bjelasica Mt. Ecological and chorological remarks are given and the conservation status is discussed for each species. This noteworthy contribution to Montenegrin bryoflora upgraded the number of mosses to 555, while the number of overall bryophytes has reached 704 taxa.
