Fungal Systematics and Evolution: FUSE 8

In this 8th contribution to the Fungal Systematics and Evolution series published by Sydowia, the authors formally describe 11 species: Cortinarius caryae, C. flavolilacinus, C. lilaceolamellatus, C. malodorus, C. olivaceolamellatus, C. quercophilus, C. violaceoflavescens, C. viridicarneus, Entoloma meridionale (Agaricales), Hortiboletus rupicapreus (Boletales), and Paraglomus peruvianum (Paraglomerales). The following new country records are reported: Bolbitius callistus (Agaricales) from Russia and Hymenoscyphus equiseti (Helotiales) from Sweden. Hymenoscyphus equiseti is proposed as a new combination for Lanzia equiseti, based on ITS and LSU sequence data in combination with morphological study

Fungal records database of Khanty-Mansi Autonomous Okrug – Yugra

The mycological research in the Northern part of Western Siberia becomes quite developed by now to be reviewed, in Khanty-Mansi Autonomous Okrug – Yugra reaching about 150 scientific works accomplished mainly from the second half of XXI century. There is even greater need in accumulating fungal records reported from different publications in a standardized regional database. This database should be organized according to contemporary demands of biodiversity informatics, to be compatible and accessible by other researchers. Organized in 2016, the Fungal Records Database of Yugra, presently contains about 14000 records of 2500 species of fungi and fungi-like organisms recorded in the area. This paper describes the database organization and accumulated fungal records and introduces the research conducted in the field of mycology in Yugra from the beginning of the XX century up to present

The communities of terrestrial macrofungi in different forest types in vicinities of Khanty-Mansiysk (middle taiga zone of West Siberia)

The diversity of macrofungi in the vicinities of Khanty-Mansiysk (Yugra, Russia) was surveyed using a method of permanent sampling plots. Ten plots, each consisting of a number of micro-plots, were established in several different communities ranging from old-growth mixed taiga forest to its derivatives in cutting succession and bogged areas. For more complete registration of the mycota, plots were supplemented with random walking routes directly nearby. Survey results were subjected to various quantitative analyses which allowed not only to evaluate the diversity of fungi but also to obtain valuable information on occurrence, abundance and ecology of individual species as well as community structure and its dynamics in the course of ecological succession. The paper reports the results of the first year of observations. 460 species of terrestrial macrofungi revealed in a poorly explored area in middle taiga of West Siberia. The plot-based study revealed differences between communities of terrestrial macrofungi of old coniferous forests, their after-cutting secondary formations and bogged stages. The survey allowed to reveal records of 3 species listed in the Red Data Book of Russia and 9 species listed in the Red Data Book of Yugra

<b>New species of </b><b><i>Hohenbuehelia</i></b><b> (Pleurotaceae, Agaricales) from Northwestern Siberia, Russia</b>

During the surveying of fleshy fungi of the Khanty-Mansi Autonomous Okrug–Yugra region (Northwestern Siberia, Russia), we found a distinct new species of Hohenbuehelia (Pleurotaceae, Agaricales). This paper is devoted to the morphological and ecological description of the new Hohenbuehelia and its phylogenetic position among the currently described species of this genus with publicly available ITS sequences. The new species differs reliably from other known species of the genus by the combination of strongly developed tomentum, dark lamellae, copiously encrusted metuloids and abundant crystals embedded in the pileipellis</p

DNA-based occurrence dataset on peatland fungal communities studied by metabarcoding in north-western Siberia

The paper represents the first DNA-based occurrence dataset on peatland fungal communities published for north-western Siberia, the first for Russia and complements several existing datasets on metabarcoding of peat soils globally.The aim of the present publication is to describe the first DNA-based occurrence dataset on fungal communities in peat soils and other substrates studied by the eDNA approach in the Mukhrino raised bog, located in a large paludified area of north-western Siberia. A comparison of the species diversity of larger fungi identified by the conventional approach and by eDNA showed a high proportion of shared taxa. Other groups (mainly Ascomycota), described by metabarcoding, revealed high diversity compared with conventional observation. Overall, the species richness identified in one peatland locality (the Mukhrino Bog) was comparable in number of species to the global estimation of fungal diversity in peatlands, previously reported in literature
