Abstract. The article describes the results of studying mycobiota in Olkhovsky district located in the Central part of Volgograd region. The standard protocol included methods of collecting, photographing in natural and laboratory conditions. To identify the material Mikmed-5 binocular microscope, Levenhuk C510 NG camera and a standard set of reagents (alkali solution, Melzer reagent) were used in the laboratory of Experimental biology of Volgograd State University. The works of Russian and foreign mycologists such as M.A. Bondartsev, V.M. Kotkov, L.G. Perevedentseva, T. Niemelä, L. Ryvarden became a base for determining fungi. The specimens were cut in half before drying and dried at a temperature of 38° C. Dried samples placed in paper envelopes are stored in the Mycological herbarium of Volgograd State University. Freezing of aphyllophoroid fungi for a month was a necessary procedure before placing it in a mycological herbarium. As a result of preliminary studies from September to November 2019, we identify nine species of basidiomycetes such as Bovistella utriformis (Bull.) Demoulin et Rebriev, Fomes fomentarius (L.) Fr., Lepista personata (Fr.) Cooke, Marasmius oreades (Bolton) Fr., Phellinus igniarius (L.) Quél., Pholiota populnea (Pers.) Kuyper et Tjall.- Beuk., Pleurotus ostreatus (Jacq.) P. Kumm., Saproamanita vittadinii (Moretti) Redhead, Vizzini, Drehmel et Contu, and Schizophyllum commune Fr. The article presents an annotated list of fungi with the indication of data on the location, substrate, frequency of occurrence and the name of the collector, if the collection was not carried out by the authors, for each type. Species names were accepted according to CABI “Index Fungorum” international electronic database (www.indexfungorum.org) as of December 2019. The trophic analysis of the composition of macromycetes shows that the largest number of species was found on dead branches and trunks, as well as live weakened trees of Fraxinus lanceolata Borkh., Populus nigra L., Salix alba L. This study of mycobiota in Olkhovsky district will be continued.

Key words: Olkhovsky district, Volgograd region, mycobiota, taxonomic analysis, mycological herbarium, basidiomycetes, macromycetes.
