Fungi (including lichen-forming fungi) and bryophytes constitute a major component across most ecosystems on Earth. With a known species diversity of 120 000 fungi and 20 000 of bryophytes, the impact of these species to their ecosystems and all life is crucial. Knowledge of species diversity of fungi and bryophytes is essential for understanding the sustainability of ecosystems and their resilience against environmental perturbation. The target of research of our team is the global diversity of fungi and bryophytes.
