On October 25-26th the HLP-Tag 2022 took place in Uden, Netherlands – that was the event for exotic mushrooms cultivation. According to the organizing committee, more than 130 people met there.

“The HLP-Tag was organised by Ulrich Groos who has founded and leaded the HLP for 28 years. So, the official organiser is the HLP which is an association of exotic mushroom producers represented by Ulrich Groos. He actually stepped back and so the day was moderated by me as I will be the new CEO of the association from the 1th of December”, – tells UMDIS Evelin Krolopp, the new organizer who has a scale plan of event future development.

So, the organizer of HLP-Tag 2022 is Hessian State Section for Mushroom Cultivation (HLP) – mushroom association, which was founded in Hesse, German in 1994 to promote mushrooms. Usually, association hosts a mushroom conference in autumn. UMDIS Mushroom Information Agency knows how it looked like this year.


This year event gathered producers of spawn, substrate and exotic mushrooms, as well as researchers who were coming from Germany, Netherlands, Belgium, Poland, Hungary, Austria, Switzerland and Israel to discuss the future of European exotic mushroom production.

Lectures of the day focused on substrate production. Patrick Romanens spoke about the advantages and disadvantages of both pasteurisation and sterilisation differentiated by mushrooms and kind of substrate. Dr. Guido Albert spoke about the evidence of bacteria in substrate and their impact to the growth of the mycelium.

“Beside that a lot of different lectures related to exotic mushrooms where held: from illumination and climatization over the problem of residuals in mushrooms and the European norms until the use of used substrate”, – tells UMDIS Evelin Krolopp.

In the program of the conference were some tours. To see VEME Specials – a substrate production of mainly Oyster mushroom, Shiitake and Piopino. After that participants went to see the mushroom production Verbruggen Paddestoelen.

“Yes, the conference in Netherland went very well. Also it was not a big conference – but it was very interesting”, – tells to UMDIS his opinion Davide Ranzato, from Vierrebi, Italian company that supplies equipment and was present during the event.

During the conference members assembly of the HLP elected a new board. Ulrich Groos after 28 years after founding and leading the association has stepped back as a CEO and the new CEO Evelin Krolopp was introduced.On the photo from left: Evelin Krolopp CEO (Germany), Arno Kubach (Germany),Torsten Jonas (Germany), Kasper Moreaux President (Belgium), Patrick Romanens Vice President (Schwitzerland), Arend van Peer (Netherlands), Kurt Pleunis (Netherlands), John Verbruggen (Netherlands) Not at the picture: Michael Böging and Christian Schmaus (both Germany).
