The paper presents the first analysis of crowdsourcing data of all observations of fungi (including lichens) and myxomycetes in Northwestern Siberia uploaded to iNaturalist.org to date (24.02.2022). The Introduction presents an analysis of fungal diversity crowdsourcing globally, in Russia, and in the region of interest. Materials and methods describe the protocol of uploading data to iNaturalist.org, the structure of the crowdsourcing community, initiative to revise the accumulated data, procedures of data analysis, and compilation of a dataset of revised crowdsourced data. The Results present the analysis of accumulated data by several parameters: temporal, geographical and taxonomical scope, observation and identification efforts, identifiability of various taxa, species novelty and Red Data Book categories and the protection status of registered observations. The Discussion provides data on usability of crowdsourcing data for biodiversity research and conservation of fungi, including pros and contras. The Electronic Supplements to the paper include an annotated checklist of observations of protected species with information on Red Data Book categories and the protection status, and an annotated checklist of regional records of new taxa. The paper is supplemented with a dataset of about 15 000 revised and annotated records available through Global Biodiversity Information Facility (GBIF). The tradition of crowdsourcing is rooted in mycological societies around the world, including Russia. In Northwestern Siberia, a regional mycological club was established in 2018, encouraging its members to contribute observations of fungi on iNaturalist.org. A total of about 15 000 observations of fungi and myxomycetes were uploaded so far, by about 200 observers, from three administrative regions (Yamalo-Nenetsky Autonomous Okrug, Khanty-Mansi Autonomous Okrug, and Tyumen Region). The geographical coverage of crowdsourcing observations remains low. However, the observation activity has increased in the last four years. The goal of this study consisted of a collaborative effort of professional mycologists invited to help with the identification of these observations and analysis of the accumulated data. As a result, all observations were reviewed by at least one expert. About half of all the observations have been identified reliably to the species level and received Research Grade status. Of those, 90 species (195 records) represented records of taxa new to their respective regions; 876 records of 53 species of protected species provide important data for conservation programmes. The other half of the observations consists of records still under-identified for various reasons: poor quality photographs, complex taxa (impossible to identify without microscopic or molecular study), or lack of experts in a particular taxonomic group. The Discussion section summarises the pros and cons of the use of crowdsourcing for the study and conservation of regional fungal diversity, and summarises the dispute on this subject among mycologists. Further research initiatives involving crowdsourcing data must focus on an increase in the quality of observations and strive to introduce the habit of collecting voucher specimens among the community of amateurs. The timely feedback from experts is also important to provide quality and the increase of personal involvement.
The authors of this paper summarize the majority of published data on the distribution of agaricoid and boletoid fungi recorded in Russia, covering the period from 1824 through 2020. A comprehensive list of 6867 scientific names based on 954 publications was compiled for the first time for the whole territory of Russia. All records have been checked through Index Fungorum. The work consists of a review section and five appendices. The review section discusses the intensity of field research and accumulation of data on the distribution of agaricoid and boletoid fungi in Russia, both historically and in its current state. The authors discuss the current state of knowledge on the biodiversity of regions of Russia and point out blank spots, thus providing a reference and an “action plan” for the future. Appendix A presents a list of 6142 taxa unambiguously ascribed to 3246 accepted current names. Appendix B contains 727 names that cannot be ascribed to any accepted current names unequivocally, with reasons given (e.g., no current name, wrong authors’ citations, absence from Index Fungorum). Names from both checklists are supplemented with data on the distribution of these taxa within the Russian Federation and references to published records. Appendix C contains a list of accepted current names reported from only one region. Appendix D is an overview of the nearly 200 years of research of agaricoid and boletoid fungi for all regions of Russia. Appendix E is a list of references used for checklists and study history preparation.
During an expedition in 2018 to Teletskoye Lake, Altaiskiy Nature Reserve and Gorno-Altaysk area (Altay Republic), 49 Cortinarius species were collected and documented, including ITS DNA sequencing of 32 samples. A total of 29 telamonioid species, 3 dermocyboid species, 6 anomaloid species, 6 phlegmacioid species, 3 myxacioid species and 2 species from other groups were found, of which 32 species are new to Altay and 14 species new to Russia. The Cortinarius funga of the Pinus-Betula-Abies forests of Altay is apparently very similar to that of boreal North Europe, and indicates a remarkable uniformity of the taiga from Scandinavia to western Siberia, with respect to fungal communities. Cortinarius privignipallens coll., C. subheterocyclus, C. nodosisporus appeared to be rare Eurasian species. A few undescribed species were also recorded, but since belonging to species complexes, they need further studies. Most of Cortinarius species (33) were found in Pinus sylvestris (Betula) mossy delta forests on sand/pebbles, whereas 9 species were found in the Pinus sibirica-Abies sibirica-Betula mixed tall herb slope forests. A few species were also found in the Alnus viridis subsp. fructicosa-Salix viminalis (Betula) riparian delta forest (3 taxa). Altogether 13 species were recorded in the calciphilous semi-open, partly grazed Betula pendula woodland around Gorno-Altaysk.
Hohenbuehelia filicina, a new species from Southwestern Siberia, Russia is described. It is morphologically, ecologically and phylogenetically well differentiated from the other species of the genus. The unique combination of morphology (relatively long stipe, white fruitbodies) and substrate preference (growing exclusively on live ostrich ferns) make the species easily recognizable even in the field. Phylogenetic analysis was performed to confirm the identity of new species.

Data on localities, habitats, distribution of recorded species are provided.
