The known, the unknown, and the expected: 130 years of research on non-lichenized fungi and fungus-like organisms in the białowieża primeval forest, Poland

Abstract

The history of mycological research and current activities in the Polish part of the Białowieża Primeval Forest are presented. The review of literature-derived and unpublished data on species of non-lichenized fungi and protozoan and chromistan fungal analogues indicates a min-imum of 3504 species observed in this area. The gaps in the exploration of fungi: unstudied taxa, plant communities, habitats, hosts, and substrates, as well as the limitations of former studies, are discussed. Our estimates show that a total of 8000 fungal species possibly occur in the Białowieża National Park alone, and more than 10,000 are expected to be found in the Polish part of the Białowieża Primeval Forest. Despite more than a centennial history of mycological research, the majority of data come from only a few older scientific projects and several more recent citizen-sci-ence-related activities, emphasizing the need for a modern, interdisciplinary study on the diversity and ecology of fungi in this area.
