                  <jats:p>Fungi have been used by humans since prehistoric times. Informal structures or groups for knowledge exchange regarding mushrooms and lichens probably existed for ages. Only recently, mycological activities have been structured in formal organizations. And where until a few centuries ago there were only learned societies and naturalists’ clubs, nowadays also mycological societies and citizen scientists have joined the landscape. However, the history of mycological organizations and activities in Europe is difficult to track. Here, we initiated two surveys to characterize the current landscape of mycological organizations focused on fungal diversity across Europe and to collate citizen science activities mapping fungi. The surveys were shared on social media and sent to mycologists in 49 countries in Europe. Responses of the surveys allowed us to present the history, geographical distribution, and structure of mycological organizations in Europe as well as their types of activities, including the publication of journals and magazines, the organization of meetings and educational initiatives, and citizen science projects. In addition to the surveys, local mycologists presented expert knowledge for a more comprehensive overview. Our data show that the mycological landscape in Europe is diverse and heterogeneous. We discuss ways to overcome economic, cultural, and linguistic barriers towards better integration of mycological communities, activities, and data in Europe. Mycological societies focused on studying fungal diversity can be leveraged towards common goals that include raising public awareness, data integration, uniting academics and non-academics, and developing common standards for research and communication.</jats:p>},

abstract = {Abstract Many social insect species build nests, which differ from the surrounding environment and are often occupied by specific organismal communities. These organisms may interact mutualistically or parasitically with the nest-builders, or simply co-occur, being able to survive in these microenvironments. In temperate forests, red wood ants (e.g. Formica polyctena) are known to create distinct, highly developed nests, which consist of large, above-ground mounds, built primarily out of plant matter collected from the forest litter. The microorganismal communities of such mounds remain understudied. As representatives of Mucoromycota fungi commonly engage in the decomposition process of the forest litter, they would be expected to occur in the mounds. However, it is still not known whether the Mucoromycota community of these ants' nests differ from the one of the surrounding forest litter. In order to distinguish mound-associated taxa, we characterized Mucoromycota communities of Formica polyctena mounds and the surrounding forest litter. We sampled four sites, twice in a season. Sampled material was plated on agar media and emerging Mucoromycota colonies were identified based on their morphology. Fungal identification was further confirmed using DNA barcoding. In order to compare described communities, PERMANOVA test and non-metric multidimensional scaling ordinations were used. To distinguish taxa associated with the mounds, multilevel pattern analysis was performed. Our results show that the Mucoromycota community of Formica polyctena's mound differs from the community of the surrounding forest litter. While representatives of Entomortierella lignicola and Absidia cylindrospora clade were found to be associated with the mound environment, representatives of Umbelopsis curvata and Podila verticillata-humilis clade were associated with forest litter, and were rarely present in the mounds. Our findings strongly suggest that the red wood ants' nest is a specific microenvironment in the temperate forest floor, which is a preferred microhabitat for the mound-associated Mucoromycota, possibly adapted to live in proximity to ants.},
