The bryophyte flora and vegetation on dead beech trees in two Slovenian near-natural forest stands is described. A total of 213 trees were investigated, 110 in the Rajhenav Forest Reserve and 103 in the Krokar Forest Reserve. Species richness, frequency, distribution of taxonomic types and ecological categories were estimated. Altogether 103 species were recorded, 96 in Rajhenav and 66 in Krokar, among which several species that are threatened in Europe: Anacamptodon splagnoides (Brid.) Brid, Buxbaumia viridis Brid. ex Moug & Nestl., Dicranum viride (Sull. & Lesq.) Lindb. and Zygodon forsteri (Dicks.) Mitt. Their frequency is low except for Dicranum viride, a common epiphyte in Rajhenav. According to the species lists, the frequency of rare species and the occurrence of threatened species the near natural forests in southern Slovenia should be considered as hotspots in biodiversity of dead wood living bryophytes in Europe. The species richness is very high, especially in Rajhenav.
