Georeferenced Checklist and Occurrence Dataset of Slime Moulds (Eumycetozoa) Across Central and Eastern Europe Emphasising Forest Ecosystems

This dataset assembles georeferenced, presence‑only occurrence records and a taxonomically standardised regional checklist of slime moulds (Eumycetozoa) from 16 countries across Central and Eastern Europe. Coverage emphasises forest ecosystems and complements each record with harmonised descriptors of substrate, stand type, and management pressure. Environmental attributes (including elevation, precipitation, pH, stand age, and consolidated forest class) enable comparative ecological and biogeographic analyses, forest‑focused modelling, and gap mapping. Full source citations are provided for all records.
