Post-fire macrofungi in the burnt area in the Jelonka reserve (Białowieża region, NE Poland)

In the burnt area of the Jelonka nature reserve near Białowieża Primeval Forest mycological studies were carried out in the years 1994-1999. Carpophores of all macrofungi were identified and counted on 7 permanent observation plots repesenting different successional stages before the fire. Altogether 250 species of macromycetes were found, among them 16 species of post-fire fungi. Pholiota carbonaria and Tephrocybe anthracophila were the most abundant and frequent species occurring in the first years after the fire. It has be~ revealed that the presence of carbonised substrate is a limiting factor for the occurrence of post-fire Basidiomycetes
