An interesting possibility for long-distance dispersal is for decay mycelia inhabiting logs that are washed from banks into rivers and transported to the open sea. Such logs are known to be able to drift for long distances from Siberian rivers to the Arctic region, later being washed up on shores hundreds of kilometres away in Iceland and Greenland. This potential route for long-distance migration of decay fungi has not been studied in detail and should attract more attention. It has implications both for understanding evolutionary history and quarantine issues.
