(2019): Macrofungi on fallen oak trunks in the Białowieża Virgin Forest – ecological role of trunk parameters and surrounding vegetation. – Czech Mycol. 71(1): 65–89. All groups of macrofungi were recorded on 32 large fallen trunks of pedunculate oak (Quercus robur) in various decay stages in the strictly protected zone of Białowieża National Park, Poland. The total number of species was 187 with 4–38 species per trunk. The mycobiota of individual trunks was unique, consisting of a variable set of several frequent species, a high number of infrequent to rare ones, and a considerable proportion of mycorrhizal fungi and species preferring conifer wood.
