Westerdijk Fungal Biodiversity Institute

We host 100,000 living fungi, yeasts and bacteria with the aim to explore, study and preserve

The Westerdijk Fungal Biodiversity Institute is part of the Royal Netherlands Academy of Arts and Sciences and is situated in Utrecht. It is an Academy research institute that maintains a world-renowned microbial biological resource centre of living fungi, yeasts and bacteria. It is also a centre of expertise for mycology (the study of fungi and moulds).

The institute studies fungal biodiversity in the widest possible sense. Its researchers develop and utilise a broad range of techniques for studying fungal biology, ecology, and genetics. The institute’s unique collection of more than 100,000 living strains of fungi puts it at the top of the global list of mycology research institutes. The institute provides answers to socially relevant questions concerning health, agriculture and industry.
