Contribution to biodiversity assessment of European primeval forests: new records of rare fungi in the Bialowieza Forest

The paper gives an annotated list of 40 species of macrofungi found in the Białowieża Forest recently. Two genera (Mycoaciella J. Erikss. & Ryvarden and Sphaerobasidium Oberw.) and nine species (Alnicola amarescens (Quel.) R. Heim & Romagn., Ceriporiopsis rivulosa (Berk. & M. A. Curtis) Gilb. & Ryvarden, Henningsomyces puber (Romell ex W. B. Cooke) D. A. Reid, Mycena silvae-nigrae Maas Geest. & Schwobel, Mycoaciella bispora (Stalpers) J. Erikss. & Ryvarden, Psathyrella maculata (C. S. Parker) A. H. Sm., Sphaerobasidium minutum (J. Erikss.) Oberw. ex Julich, Steccherinum tenuispinum Spirin, Zmitr. & Malysheva, and Xenasma pruinosum (Pat.) Donk) are reported for the fi rst time from Poland. A further 23 species are new for the Białowieża Forest: Antrodia mellita Niemela & Penttila, Antrodiella citrinella Niemela & Ryvarden, Asterodon ferruginosus Pat., Athelia decipiens (Hohn. & Litsch.) J. Erikss., Byssocorticium atrovirens (Fr.) Bondartsev & Singer ex Singer, Conferticium ochraceum (Fr.) Hallenb., Coniophora olivacea (Fr.) P. Karst., Crepidotus crocophyllus (Berk.)

Cooke, Pezicula acericola (Peck) Peck ex Sacc. & Berl., Piloderma byssinum (P. Karst.) Julich, Pseudomerulius aureus (Fr.) Julich, Rectipilus fasciculatus (Pers.) Agerer, Sebacina incrustans (Pers.) Tul. & C. Tul., Sistotrema raduloides (P. Karst.) Donk and Trechispora hymenocystis (Berk. & Broome) K. H. Larss. The species new for Poland are described and their micromorphological characters are illustrated.
