The xylotroph's macromycetes on beech in Azerbaijani forests.
A study was conducted to investigate the species composition and significance of beech-wood decomposing macromycetes. A total of 101 species of macromycetes were found on beech (Fagus orientalis) in Azerbaijani forests. All species of xylotrophic macromycetes belonged to 52 genera and 13 families of the orders Aphyllophorales, Polyporales, Agaricales and Auriculariales from the subdivision Basidiomycotina. Seventy-nine percent of the xylotrophic species was represented by the order Aphyllophorales, while species of Polyporales comprised 10.9%, Agaricales comprised 8.9%, and one species belonging to Auriculariales. The Poriaceae family had the most number of species and genera (58 species from 41 genera). The intensive destroyers of beech wood in forests are Polyporus squamosus, Fomitopsis pinicola, Fomes fomentarius, Phellinus igniarius, Pholiota adipose and Ganoderma applanatum. The presence of a variety of genera and species of wood decomposing macrofungi, especially in anthropogen-affected areas, is an indicator of the destructive processes of forest ecosystems.
