Ger Van Zanen was one of the guest researchers at the herbarium of Naturalis for a very long time. He was also an enthousiastic mycologist. When he passed away a couple of years ago, he left part of his legacy to the Dutch Mycological Society (NMV, www.mycologen.nl). The NMV now decided to boost the research of Dutch mushrooms by spending part of the legacy to combine traditional morphological knowledge with molecular species delimitation and barcoding. In the next five years Jorinde Nuytinck will collaborate with Dutch amateur mycologists to add a molecular perspective to their morphological insights.
