Agarica: Special issue on slime moulds (myxomycetes) in Norway (Agarica. Mycological journal published by The Norwegian Association for Mycology and Foraging #40) ebok

New and rare myxomycetes (Mycetozoa, Myxogastria) in Norway, including a complete checklist of Norwegian myxomycete species Agarica 40 (2020) is a special issue where Edvin Johannesen and Per Vetlesen present 130 myxomycete species and 8 varieties as new to Norway, and an additional 43 species previously reported from Norway, which are considered regionally rare. A complete checklist of Norwegian myxomycetes (363 species) is also presented. Johannesen and Vetlesen have been working on this project for several years. Through this work, more than 100 species not previously known from the Nordic region, are now known from Norway. Several of these species have previously been reported from less than five countries worldwide. The current understanding of the role and importance of the various myxomycete species in various biotopes is inadequate. Very few myxomycete species are red listed. The potential for further increasing the knowledge of the distribution and ecological significance of myxomycetes is considerable. This special issue will contribute to such knowledge and may furthermore stimulate the interest in, and the increased search for and mapping of myxomycetes among dedicated amateurs. This paper is also a source of information about deposited specimens of rare species and taxonomically difficult groups, which may contribute to the clarification or revision of such species or groups. Several specimens have already been provided for sequencing by researchers working on the revision of certain genera. Edvin Johannesen has a formal education in biology, specialising in mycology. He wrote his thesis on the myxomycetes of Norway in 1982 and has later written scientific papers and given lectures about myxomycetes. Per Vetlesen has a formal education in forestry engineering and pedagogy. For 35 years he was teaching forestry and open air life at agriculture colleges. The last 10 years have been dedicated to the mapping and study of myxomycetes. Agarica.no Editors: Anders K.
