Fungi (agaricoid basidiomycetes) of the Pechoro-Ilych reserve (Komi Republic, Russia)

Study Extent

The dataset includes species registrations of fungi made within the borders of Pechoro-Ilych Nature reserve. This study was carried in the foothill and mountain landscapes of the Northern Urals, in the basins of the Pechora and Ilych Rivers.

Sampling

The authors contributing to the dataset used standard methods of fungi collection. The results of this study were documented in the Herbarium (SYKO). All samples were cited in the literature.

Quality Control

All specimens were collected and identified by authors’ dataset from the Institute of Biology of Komi Scientific Centre of the Ural Branch RAS. Some specimens were verified mycologist from Komarov Botanical Institute RAS. Taxonomic names spelling were verified using Index Fungorum database. Taxonomic names were brought to modern synonyms by the same source.

Method steps

1. The data of long-term field studies of the authors conducted in the Pechoro-Ilych Nature reserve (Komi Republic) were summarized on the MS Excel sheet. When carrying out field work, a route method was used to survey the sites typical for the growth of agaricoid fungi. For all identified locations of the speciments, geographical coordinates were recorded using Garmin CSX 60 GPS receiver (WGS 84) and a brief description of phytocenotic parameters were fixed. The herbarium label data were taken from fungi collection of Institute of Biology of Komi Scientific Centre of the Ural Branch of the Russian Academy of Sciences Herbarium (SYKO-f). The every occurrence record where merged into one MS Excel sheet. In the database record the following parameters: species name, collector, identifier, date of record, locality description, site charasteristic. Georeferencing was performed according to the method described in the publication "Guide to best practices for georeferencing" (Chapman, Wieczorek, 2006). Georeference of occurrence record where made with the help of available topomaps to the territory of the Komi Republic. For rough reference used maps with a scale of 1: 200000. More accurate binding was carried out according to the satellite images presented on a publicly accessible Internet resources (https://wego.here.com; https://yandex.ru/maps, etc.). The main number of identified fungi species is classed as low sensitivity species via categories of sensitivity provided by A.D. Chapman and O. Grafton (2008). Therefore, the data presented were denatured to 0.001 degrees (≈100 m). Data may bу supplied at finer scales on request to Authors under the conditions of a Data License. The species name were given according to “Index fungorum” internet resource (http:// http://www.indexfungorum.org).

453 species and intraspecific taxa of agaricoid basidiomycetes have been found in the Pechoro-Ilych Nature reserve. All of them belong to agaricoid basidiomycetes (phylum Basidiomycota, class Agaricomycetes) include higher basidiomycetes known as mushrooms and toadstools (agarics and boletes). A total of 5 orders are represented, with Agaricales (362 species, 992 specimens), Russulales (54 species, 160 specimens), Boletales (33 species, 104 specimens) constituting about 99% of the collection. The spectrum of leading families and genera is generally characteristic of boreal biotas, as evidenced by the high species diversity of the families Cortinariaceae (12.7%), Russulaceae (11.4%), Tricholomataceae (7.9% of the total species diversity) and genera Cortinarius (8.6%), Inocybe (5.5%), Mycena (5.1%), Russula (4.0%) и Lactarius (3.8).

Pechoro-Ilych Nature Biosphere reserve is the largest in Europe protected area where arrays of natural virgin forests are protected (total area about 721.3 thousand ha). Now the reserve territory consists of two isolated parts. The main part is located in the Pechora and the Ilych rivers interfluve in foothills and mountains of Northern Ural. The other smaller part is located on the Pechora river lowland, near Yaksha village. The reserve territory lies on the border of plain and Ural Mountains.
