AbstractThe Białowieża Forest (BF) is one of the best-preserved lowland deciduous and mixed forest complexes in Europe, rich in diverse fungi. This paper summarizes what is known about the poroid fungi of the Polish part of the Białowieża Forest, based on literature data, a re-examination of herbarium materials, and the authors’ studies from 1990–2014. An annotated catalogue of polypores recorded in the forest is presented, including 80 genera with 210 species. All literature and herbarium records are enumerated, and 160 species are illustrated with color pictures. Fourteen species previously reported in the literature have uncertain status because they lack voucher specimens and were not confirmed in recent field studies. Antrodiella subradula (Pilát) Niemelä & Miettinen, previously known from Asia, is reported for the first time from Europe. Fourteen species are newly reported from the Białowieża Forest (mainly from Białowieża National Park), including 8 species with first records in Poland (Antrodia hyalina Spirin, Miettinen & Kotir., Antrodia infirma Renvall & Niemelä, Antrodiella subradula, Junghuhnia fimbriatella (Peck) Ryvarden, Postia folliculocystidiata (Kotl. & Vampola) Niemelä & Vampola, Postia minusculoides (Pilát ex Pilát) Boulet, Skeletocutis chrysella Niemelä, Skeletocutis papyracea A. David), and 6 species reported previously from other localities in Poland [Antrodiella faginea Vampola & Pouzar, Dichomitus campestris (Quél.) Domański & Orlicz, Loweomyces fractipes (Berk. & M. A. Curtis) Jülich, Oxyporus latemarginatus (Durieu & Mont.) Donk, Perenniporia narymica (Pilát) Pouzar, Phellinus nigricans (Fr.) P. Karst.]. Several very rare European polypores already reported from the Białowieża Forest in the 20th century, such as Antrodia albobrunnea (Romell) Ryvarden, Antrodiella foliaceodentata (Nikol.) Gilb. & Ryvarden, Buglossoporus pulvinus (Pers.) Donk, Dichomitus albidofuscus (Domański) Domański and Gelatoporia subvermispora (Pilát) Niemelä, were found at new localities, confirming their continuous occurrence in this forest.
