The Westerdijk Fungal Biodiversity Institute (previously known as the CBS-KNAW Fungal Biodiversity Centre) - an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW) and situated in Utrecht - maintains a world-renowned collection of living filamentous fungi, yeasts and bacteria.

The Institute's research programs principally focus on the taxonomy and evolution of fungi as well as on functional aspects of fungal biology and ecology, increasingly making use of molecular and genomics approaches.

The institute employs circa 70 personnel, among whom 20 scientists. The Collection now maintains over 80.000 – 100.000 strains of micro-organisms, representing a large percentage of the species in the fungal kingdom that have been cultured to date. In diversity of species it is unchallenged as a reference centre for mycological research.
