Abstract. The article presents an annotated list of 40 species of aphyllophoroid fungi revealed in Shebekinsky district of the Belgorod Region in August 2019. Twenty-one of the species are new to the Belgorod Region (including Dendrothele alliacea, Dichomitus squalens, Hydnoporia tabacina, Hyphodontia pallidula, Kneiffiella subalutacea, Lentinus arcularius, Leptosporomyces galzinii, Meruliopsis taxicola, Mucronella calva, Peniophora incarnata, Phanerochaete alnea, Tubulicrinis calothrix, Xylodon asperus, etc.). Most of the revealed species (70%) were found on the dead wood of Pinus sylvestris which is the main forest-forming tree on the studied territory. The species Leptoporus mollis is strongly recommended to be included into the Red Data Book of the Belgorod Region.

Introduction
Aphyllophoroid fungi represent the non-taxonomic group of basidiomycetes, which are the key dead wood decomposers, with the exception of some ectomycorrhizal representatives, and are predominantly associated with forest ecosystems (Bondartseva, 2000). A number of regions in the center and the south of European Russia are characterized by sparse forest areas that have been undergoing continuous fragmentation for several centuries. The Belgorod Region, located in the southwestern part of the Central Russian Upland, is one of the regions of the forest-steppe zone, where forest ecosystems have been preserved mostly within the boundaries of specially protected natural areas. To date, 170 species of aphyllophoroid fungi have been registered in the Belgorod Region (Brezhnev, 1950; Ryabova, Ignatenko, 1981; Nikolaev, 1986; Psurtseva et al., 2003; Volobuev et al., 2015;

Bolshakov, Volobuev, 2016; Volobuev, Bolshakov, 2016; Volobuev et al., 2019). The purpose of this survey is to obtain new data on the species diversity of aphyllophoroid fungi and the plant substrates they inhabit in the previously unexplored regionally valuable protected area in Shebekinsky district of the Belgorod Region.
Materials and methods
Collection of specimens of aphyllophoroid fungi basidiomes was made by a route method within the regionally valuable protected area «Quarters N 12, 13, 14, 18, 19, 20 of the A r-khangelsk area of Shebekinsky forestry» with a total area of 2,9 km2 in August 2019. The coordinates of the terminal points of the transect are N 50.38486°, E 36.83240° and N 50.37730°, E 36.83051°. The main forest types explored were pine -dominated forests with oak, elm, maple and hazel as well as herb-rich pine forests. Identification of the collected field materials was performed using modern methods of light microscopy. The specimens are deposited in the Mycological Herbarium of the Komarov Botanical Institute of the Russian Academy of Sciences (LE) and the mycological collection of the V. N. Khitrovo Herbarium of the Oryol State University named after I. S. Turgenev (OHHI).

Most of the species (28 species, or 70%) are found on Pinus sylvestris, which is the main forest-forming tree in the studied area. The presence of pine has determined the occurrence of such species as Auriscalpium vulgare, Dichomitus squalens, Hyphodontia pallidula, Phan-erochaete sanguinea, Skeletocutis carneogrisea, etc., associated with coniferous trees. Among them, several fungal species (Postia leucomallella, Trichaptum fuscoviolaceum, Xylodon asper-us) were also registered in forest-steppe zone of the Central Russian Upland on the territory of the Oryol Region (Volobuev, 2013).
The most remarkable species for conservation purpose is presented by Leptoporus mollis which is known in the European part of Russia based on records predominantly from boreal and hemiboreal forests. The occurrence of the species closest to our find is cited from the protected area of the Voronezh Biosphere Reserve (Kotkova, 2019). Ecological preferences of the species are determined by the presence of large-size dead wood of coniferous (Picea spp., Pinus spp.) and by the absence of anthropogenic habitat disturbance. The species Leptoporus mollis is strongly recommended to be considered for including into the Red Data Book of the Belgorod Region.

Conclusion
As a result of the short-time mycological observation on the territory of Shebekinsky district of the Belgorod Region 40 species of aphyllophoroid fungi were revealed. Among them 21 species were registered for the first time in the region. The predominance of fungal species developing basidiocarps on dead wood of Pinus sylvestris is connected with the role of this plant as the main forest-forming tree.
The study was carried out within the framework of research project of the Komarov Botanical Institute RAS «Herbarium funds of the BIN RAS (history, conservation, study and supplementation)» (АААА-А18-118022090078-2) and was financially supported by the Grant of the President of the Russian Federation for state assistance of young Russian scientists - candidates of sciences (MK-3216.2019.11).
