About the the Dutch Mycological Society
The Nederlandse Mycologische Vereniging (Dutch Mycological Society, NMV) was founded on 17 october 1908 with the purpose to promote mycology, the study of fungi. The Society currently counts about 800 members, who occupy themselves with mycology on different levels – novice or advanced, amateur or professional.

To achieve her goals, the Society has a number of special interest committees, publishes 'Coolia' and other publications and organises and/or coordinates amongst others National meetings, Excursions, Study weeks and Courses.

Also, the society possesses an extensive library, currently housed by the Centraal Bureau voor Schimmelcultures (CBS) in Utrecht. This library contains a large number of (partly rare) books, periodicals and reprints, that can be consulted or borrowed by members of the Society without cost.

For the last few years the NMV has participated, together with a large number of other Private Data-managing Organistions (PGOs), in the Foundation for Field Research into Flora and Fauna (VOFF). The VOFF has its own website.
The NMV co-operates with the GaN (Data Authority for Nature). One of the most important GaN activities is setting up and managing the National Databank for Flora & Fauna (NDFF). The NDFF has been developed together with the Flora & Fauna Field Research Foundation (VOFF), the Institute for Biodiversity and Ecosystem Dynamics of the University of Amsterdam and the GaN. The NDFF is a database with up-to-date and reliable information about the distribution of all species of plants, animals and fungi living in The Netherlands. Existing data are being collated and new data collected. It is the first fully-fledged system in The Netherlands to gather, systematize, validate and make nature data accessible in a simple way. Information from the NDFF will be available from Het Natuurloket (the Nature Counter).
For more information about the NDFF see the GaN website.


Mycological forays are organised every week from April to December and spread over the whole country. Although these excursions are in principle open to all interested persons, they cannot be compared to a “mushroom ramble with the forest warden”. Every foray has a scientific aim: to increase (one’s own) knowledge of our mycoflora and to map the distribution of mushroom species. An outsider can be easily swamped by the quantity of information and unfamiliar jargon, but those who are really interested can soon be infected with the mushroom virus and before long will want to join our society!

National meetings

In winter and spring the NMV organises three national meetings. Dates (as far as known) can be found in the agenda.
  • The New Year's meeting is traditionally organised on one of the first saturdays in the new year. Its programme comprises lectures (usually accompanied by slides) on diverse subjects, and there are several indispensable items for sale, like mycological literature, chemicals and coffee with cake.
  • The so-called Floradag is organised by the Scientific Committee, in march or april. This is a meeting with lectures on a specific theme, like taxonomy, ecology, nature conservation etc. In some cases, the text of the lectures is published in the series of Scientific Communications of the Royal Netherlands' Society for Natural History (KNNV).
  • The general assembly, finally, generally takes place in april, covering, apart from the business part, an afternoon programme on actual mycological subjects.

Study weeks

Every year, the NMV organises two study weeks, one inland and one abroad. Both forays are based in a group accomodation with ample space to work, and provide an excellent opportunity for an intensive acquintance with the fungi of a specific area. The foray abroad is preferentially organised in areas containing vegetation types that are unknown or rare in the Netherlands, in order to allow the study of mushroom species that are rare or absent in our country. The inland foray has lately been based in those regions that are relatively sparsely visited for the mapping project.
Both forays have participation of both advanced and starting mycologists, and therefore provide a perfect opportunity for exchange of knowledge. Especially the inland foray is very suitable for beginning mycologists who would like to experience the life of fanatics, and/or the fine touch of microscopy, and/or the fungal marvels of sometimes seemingly uninteresting areas.
Dates and locations of the next foray weeks (if known) can be found in the agenda.


Every year, the Scientific Committee organises one or a few seminars for beginning or advanced amateur mycologists. They are usually devoted to a specific topic, like taxonomy of genera like Mycena, Russula or Cortinarius, or more practical matters like making useful descriptions or microscopy courses.
Information on courses planned for the current year (as far as known) can be found in the agenda.

Membership information

Membership fee for the NMV amounts to €35,-- per annum (€ 17,50 for additional family members). It includes 4 issues of Coolia, and entitles to participate in all activities of the Society. Moreover, publications by (members of) the Society can generally be purchased at reduced cost. Joining the Society is easy. If you would like to become a member, click here.
