Population genomics of a rare and a common wood-inhabiting fungal species across Europe

Many species have become threatened during the Anthropocene, requiring conservation strategies based on biological evidence. Wood-inhabiting fungi face multiple threats due to a complex interplay of a short lifespan, removal of dead wood as a resource, and climate change. Furthermore, rare fruiting events might restrict dispersal via spores, leading to significant population genetic structure. Yet, little is known about the genetic structure of both rare and common wood-inhabiting fungal species across Europe. Here, we investigate the rare polypore fungus Antrodiella citrinella, which co-occurs with the common wood-decay fungus Fomitopsis pinicola. We analyzed a total of 149 individuals of both species across 13 countries, sequenced their genomes, and analyzed single-nucleotide polymorphisms. Based on a broad set of analyses, we found a very weak population structure in A. citrinella, suggesting historically wide dispersal and effective gene flow across Europe. In contrast, we found sup..., , # Data from: Population genomics of a rare and a common wood-inhabiting fungal species across Europe
