Around 80 out of the mentioned 365 species can be used as edible by men. In this context, the following are the most prominent: Amanita caesarea (Caesar's mushroom), Boletus edulis (Summer boletus), Boletus aestivalis (Cep boletus), Boletus aereus (Dark boletus) and Boletus pinophilus (Pine boletus), Cantharellus cibarius (Chanterelle) and Morchella spp. (Morels).
Certain fungi species on Sar Planina Mt. can be regarded rare species. Out of those, 18 species are considered important species for biological diversity.
The species Agaricus campestris, Agaricus macrosporus, Amanita caesarea, Auricularia auricula-judae, Basidiodendron caesiocinerea, Boletus rhodoxanthus, Boletus satanas, Boletus regius, Craterellus cornucopioides, Exidia pythia, Lopharia spadicea, Macrolepiota procera, Phlebia griseo-flavescens, Sarcodon imbricatus and Volvariella bombycina have been proposed for conservation under the Preliminary Red Book of Fungi in the Republic of Macedonia. Agaricus campestris, Agaricus macrosporus, Amanita caesarea, Auricularia auricula-judae, Boletus satanas, Boletus regius, Craterellus cornucopioides and Macrolepiota procera belong to the group of rare species that are threatened due to excessive collection.
