Аннотация

The paper continues a series of publications devoted to the new finds of macrofungi (ascomycetes, basidiomycetes) in regions of the Russian Far East. A total of 61 species and intraspecific taxa of macromycetes are reported for the first time from 6 administrative units of the Russian Far East: Amur Oblast, Jewish Autonomous Oblast, Magadan Oblast, Kamchatka Krai, Khabarovsk Krai and Primorskiy Krai. For some of the rare species, notes are given about the main differences in morphology and ecology, about the features of distribution. The identification of Granulobasidium vellereum, Scleroderma venenatum, Phallus ultraduplicatus, Echinochaete russiceps, Phanerochaetella angustocystidiata, and Hyphoderma mopanshanense species by morphological methods is confirmed by molecular genetic data. Some species were isolated into pure culture (Granulobasidium vellereum, Phallus ultraduplicatus, Echinochaete russiceps). The material was deposited in VLA, MAG, SVER, LE F herbaria and in the Yu. Rebriev (YuR) personal collection. 17 species are reported as the first records for the Russian Far East, and 7 (Aureoboletus auriflammeus, Hyphoderma mopanshanense, Echinochaete russiceps, Phanerochaetella angustocystidiata, Rheubarbariboletus persicolor, Scleroderma venenatum, Singerocybe alboinfundibuliformis, Stropharia acanthocystis, Trametes hirta) are new species for Russia.

Keywords: Ascomycota, Basidiomycota, biodiversity, fungal distribution, molecular genetic identification, rare species, Russia

INTRODUCTION

The paper is a third in the series of publications devoted to the new finds of macrofungi in the regions of the Russian Far East (Rebriev et al., 2020b, 2021). The data contained in these publications are deposited on the GBIF resource (Rebriev et al., 2022).

Each annotated record provides details about specimen ecology and collection information: locality, habitat, substrate, specimen herbarium numbers, collectors and determiners as well as notes on rarity and peculiar features of some species.

MATERIALS AND METHODS

Material was collected and identified by Anna V. Bogacheva (abbreviated as AB), Eugenia M. Bulakh (EB), Nadezhda V. Bukharova (NB), Elena A. Erofeeva (EE), Eugene S. Popov (EP), Nadezhda V. Psurtseva (NP), Yury A. Rebriev (YuR), Nina A. Sazanova (NS), Anton G. Shiryaev (AS), Elena A. Zvyagina (EZ) and others, as indicated in the text. If the specimen was collected and determined by the same specialist, such notes as “coll. and det.” are ommitted in the text. Coordinates may not be specified for samples with incomplete label data. The taxa names are actualized in accordance with the Index Fungorum database (2022).

The material was accessioned in LE F (Saint Petersburg), MAG (Magadan), SVER (Ekaterinburg), VLA (Vladivostok) herbaria, as well as in the Yu. Rebriev (YuR) personal collection.

The novelty of finding the species in the region was assessed on the analysis of numerous publications. The main source of information for agaricoid and boletoid taxa is a cumulative checklist published at the end of 2021 (Bolshakov et al., 2021).

Information about the findings of some species of ascomycetes was previously given in A.V. Bogacheva’s Doctoral Thesis (Bogacheva, 2009). As Thesis represents a manuscript, we consider the data suitable to publish in present paper.

The identification was carried out mainly by morphological methods. In several cases, a molecular genetic method was used as an additional or main one. This made it possible to confirm the identification of some specimens, as well as to identify an immature fruitbodies of Phallus ultraduplicatus.

Preparation for molecular analisys of the strains was performed by sampling a small piece of basidiomata or from the advancing zone of the colonies and using Thermo Scientific Phire Plant Direct PCR Kit and standard ITS primers 1F-4b. Sanger sequencing was carried out using equipment at The Core Facility Centre at the Komarov Botanical Institute RAS.

Some specimens were isolated into pure culture. Culturing was carried out in the field stations from either fresh basidiomata tissue or spores in Petri dishes with beer-wort (4%, Severnie Pivovarny, Saint Petersburg, Russia) agar (2%, Russia). After starting of mycelium growth or spores germinated a smal pies of newly growing mycelium of each culture were transferred into a steril cryovials with the same medium for transportation and protection from contamination. The cultures vere characterised in laboratory conditions using morphological and molecular methods. The verified strains were preserved in the Komarov Botanical Institute Basidiomycetes Culture Collection (LE-BIN) using traditional preservation methods (Psurtseva, 2010) and cryopreservation at –80 °C (10% glycerol; freezing rate 1 °C min –1).
