Courses to improve Collaboration in V4 Countries to learn about Cryptic fungi
Funded by Visegrad Grant
Three institutions with strong backgrounds in taxonomy, phylogenetics, and genomics of insect-related fungi bring together researchers to share expertise with each other and students. In a series of workshops organized in three V4 countries we will tighten collaborations and stimulate knowledge exchange. A citizen science campaign and lectures open to the general public will also be organized.

19th to 21st of May 2025
The workshop took place in České Budějovice as part of the project Courses to Improve Collaboration in V4 Countries to Learn About Cryptic Fungi, funded through Visegrad Grant No. 22420237 and organized by Danny Haelewaters, László Nagy, and Julia Pawłowska. It brought together participants from several countries for a public lecture, citizen science activities, and training sessions focused on insect-associated fungi and collaborative research. A brief overview of the key events and achievements is provided in the poster below.

Phylogenomics workshop and open lecture, Urwitałt and Warsaw, Poland
8th to 11 th of December 2025
From December 8–11, 2025, a phylogenomics workshop was held in Urwitałt as part of the C4inV4 initiative, focused on strengthening collaboration among V4 countries and advancing research on cryptic fungi. The program combined inspiring open lectures by Danny Haelewaters and Anna Muszewska with intensive hands-on training led by Anna Karnkowska, supported by Beniamin Abramczyk and the organizing team. Participants also took part in field-based activities aimed at searching for and studying cryptic fungi, linking theoretical knowledge with practical biodiversity research. The workshop took place at the Mazurskie Centrum Bioróżnorodności i Edukacji “Kumak”, whose excellent facilities created an ideal environment for collaboration. The workshop brought together participants primarily from Hungary, the Czech Republic, and Poland, as well as from other European countries including Belgium and Spain, fostering a truly international exchange of expertise. The event was made possible through the dedicated support of Julia Pawłowska, Marta Tischer, Michał Gorczak, Michał Kochanowski, Igor Siedlecki, and Dorota Wiktorowicz, and was generously funded by the Visegrad Fun
