A total of 11 ascomycete and 116 basidiomycete species have been recorded for the first time from 30 administrative regions of Russia: Kabardino-Balkar Republic (6 species), Karachay-Cherkess Republic (1), Komi Republic (19), Republic of Bashkortostan (4), Republic of Dagestan (1), Republic of Mordovia (7), Republic of Tatarstan (12), Tyva Republic (5), Udmurt Republic (1), Krasnodar Krai (2), Perm Krai (5), Arkhangelsk Oblast (3), Astrakhan Oblast (1), Chelyabinsk Oblast (7), Kaliningrad Oblast (1), Kirov Oblast (4), Kostroma Oblast (9), Leningrad Oblast (13), Lipetsk Oblast (1), Murmansk Oblast (4), Novgorod Oblast (1), Oryol Oblast (1), Penza Oblast (1), Rostov Oblast (1), Sverdlovsk Oblast (4), Tyumen Oblast (10), Vologda Oblast (4), Yaroslavl Oblast (10), Saint Petersburg (1), Khanty-Mansi Autonomous Okrug (2 species). An annotated species list containing the data on location, substrate, habitat type and voucher numbers is provided. Favolaschia calocera, Hygrophorus exiguus, and Laetisaria lichenicola are reported as the first records in Russia. Acanthophysellum minor, Albatrellus citrinus, Flammula pinicola, Leptosporomyces montanus, and Tubulicrinis regificus are recorded in Russia for the second time. Gibbera andromedae, Lindtneria trachyspora, Rhodocollybia fodiens, Rosenscheldia abundans, Scutiger pes-caprae, and Xerocomellus cisalpinus are reported for the third time. Sequences of ITS nuclear ribosomal DNA from specimens of Hygrophorus exiguus and Riopa metamorphosa have been generated and submitted to the GenBank database.

Keywords: Ascomycota, Basidiomycota, biodiversity, fungal distribution, Russia

INTRODUCTION

The present report is the sixth in the series of articles devoted to the new regional records of fungi (Bolshakov et al., 2016, 2018, 2020; Svetasheva et al., 2017; Volobuev et al., 2019).

An annotation record includes the data on species location, substrate, habitat, and herbarium documentation. The material was loaded in LE (Saint Petersburg), SVER (Ekaterinburg), SYKO (Syktyvkar), INEP (Apatity), NSK (Novosibirsk), AR (Arkhangelsk) herbaria as well as in the private collections of  Yuriy A. Rebriev – YuR (Rostov-on-Don), Kim O. Potapov – PK (Kazan), Elena A. Zvyagina – EZ (Surgut). Duplicates of all specimens are stored in LE.

MATERIALS AND METHODS

Material was collected and identified by the authors abbreviated as follows: Sergey V. Volobuev (SV), Sergey Yu. Bolshakov (SB), Yuliya R. Khimich (YuKh), Anton G. Shiryaev (ASh), Yuriy A. Rebriev (YuR), Kim O. Potapov (KP), Eugene S. Popov (EP), Vladimir I. Kapitonov (VK), Marina A. Palamarchuk (MP), Lyudmila B. Kalinina (LK), Denis A. Kosolapov (DK), Iraida V. Stavishenko (IS), Lidiya G. Perevedentseva (LP), Vyacheslav A. Vlasenko (VV), Artyom V. Leostrin (AL), Anna A. Efimova (AE), Anastasiya V. Vlasenko (AV), and other experts indicated in the text.

To shorten the names of administrative regions of Russia we have used the international standard codes ISO 3166-2:RU (ISO, 2010). Republic of Crimea was abbreviated as KM.

Data on the fungal species distribution in Russia (abbreviated as D) is based on the updated database on Agaricomycetes diversity (Bolshakov et al., 2017), as well as other papers partly referenced in previous reports (Bolshakov et al., 2016; Svetasheva et al., 2017). Detailed information on the specimens examined is listed after the letter “S”.
