Abstract:  A biogeographical analysis of East Asian polypores based on species lists and Dice’s similarity index is provided. A comparison of the temperate East Asian polypore mycota with those from other north temperate areas showed that most species belong to the north temperate element, but East Asia has the highest biodiversity and degree of endemism of all north temperate areas. East Asia and East North America share the highest amount of taxa. Furthermore, several species with their main distribution centres in the palaeotropics, Australia, and even the neotropics, occur in East Asia. Their presence in this area could be related to past geological events.
