AbstractPeat-bog pine (Pinus × rhaetica) is a unique, holoarctic taxon, occurring in mountain peat-bogs in central Europe. In Poland it was found on four sites and is considered as an endangered species with a high risk of extinction in nature in the near future. The dieback of Pinus × rhaetica is worrying; in comparison to investigations 20 years ago, more than 60% of pines died off. By now over 68% of individuals have shown advanced dieback symptoms. The aim of the study was to compare the health condition of peat-bog pine with historical data and to assess the potential role of fungi in needles in the decline of the species. The study was carried out in the Great Peat Bog of Batorów in Stołowe Mountain National Park (SW Poland) in 2019. Endophytic fungi were isolated from 600 living needles. Needle mycobiota from different positions within the needle (top, middle and base) and different trees in various health conditions were compared. The composition of mycobiota varied depending on the position in the needle: potentially pathogenic species occurred at the tip of the needle, while the base was inhabited by saprotrophs. The predominant species was Lophodermium pinastri (25% of colonies). The biggest diversity was observed in the Xylariales (6 species), with the most frequent species being Biscogniauxia nummularia (10% of colonies) and Xylaria longipes (>5% of colonies). Certain fungi may probably be involved in lowering the health condition of Pinus × rhaetica.
