Abstract
We present results of the bryofloristic survey of fens and degraded fens of the National Nature Monument ‘Jestřebské slatiny’ - ‘Shnilé louky’, ‘Baronský rybník’ and meadow ‘Pod Konvalinkovým vrchem’. Seventeen species of liverworts and 70 mosses were recorded in course of several visits by the authors, of which four liverworts and three mosses are classified as threatened in the Czech Republic. The most significant record was the re-discovery of a putatively vanished moss of rich fens, Campyliadelphus elodes, at the locality ‘Pod Konvalinkovým vrchem’. Given the regional importance of the record, we performed the revision of herbarium specimens from our country and present the typification of Chrysohypnum elodes var. salinum Podp., described from South Moravia.
