![]() Is found in highland regions, growing either on slopes of hills or on The 31 localities are mostly situ-Īted in mountain regions, the highest numbe Public are summarised and the ecology of the species is evaluated. The process of oak trunk decay in relation to fungi and surrounding vegetation is outlined. Some herbs requiring nutrient-rich soils occurred in the vicinity of trunks with a larger contact area with the soil and in later stages of decay. ![]() Presence of some dominants (Ganoderma applanatum, Mycena inclinata, Kretzschmaria deusta, Xylobolus frustulatus) had a significant effect on fungal community composition. Orientation (azimuth) of the fallen trunks proved to be significant also for the fungal species composition of a particular trunk, which also reflected trunk size characteristics, its moss/bark cover and contact with the soil. The species-richest trunks were those covered by bark, of larger volume (thick, long), not exposed to heat from afternoon sun, but, simultaneously, with lower canopy cover. The number of fungal species per trunk was significantly correlated with trunk orientation, which reflects the heat load via forest canopy gap, trunk size parameters, percentage of bark cover and contact with the soil. Relations between trunk parameters, surrounding vegetation and fungal occurrences were analysed using multivariate statistical methods. ![]() The mycobiota of individual trunks was unique, consisting of a variable set of several frequent species, a high number of infrequent to rare ones, and a considerable proportion of mycorrhizal fungi and species preferring conifer wood. The total number of species was 187 with 4–38 species per trunk. Despite substantially expanding our knowledge of the mycobiota in both the Polistovskiy State Nature Reserve and Pskov region, the present data are still insufficient for a comprehensive quantitative analysis of its structure.Īll groups of macrofungi were recorded on 32 large fallen trunks of pedunculate oak (Quercus robur) in various decay stages in the strictly protected zone of Białowieża National Park, Poland. Helicogloea compressa was registered for the second time in Russia, with another record in St. We found also HemistropahriaĪlbocrenulata, a protected species in Finland and the adjacent Leningrad region and Novgorod region. With brief notes, whereas the latter are supplied with descriptions of studied specimens, drawings of microstructures and discussion of their distribution, habitats, similar and closely related species, and current state of knowledge. Among them, six species (Galerina hybrida, Gymnopus erythropus, Lepiota boudieri, Pluteus velutinus, Rugosomyces obscurissimus, and Simocybe haustellaris) were new to the Northwest of European Russia and four species (Achroomyces effusus, Botryobasidium stigmatisporum, Galerina caulocystidiata, and Pseudobaeospora celluloderma) were new for Russia. As a result, 74 basidomycete species new to Pskov region were revealed. The material was studied using the standard methods of fungal taxonomy. Polistovskiy State Nature Reserve (Pskov region, Russia) in various forest types in the core and buffer zones along nine designated In 2019, we assessed the fungal biota of the Powered by new finds in the field and advances in molecular genetics, make fungal inventorying in any territory a long-term effort rather than an isolated event. The сonstantly expanding knowledge on this vast group of organisms, Fungal inventorying studies in Protected Areas are an important part of biodiversity assessment. Prior to a present paper, 918 species of basidiomycete fungi were known in the Pskov region (Russia), including 512 species recorded in the Sebezhskiy National Park. bialoviesense from Boubínský prales and Białowieża are provided. Photographs of dried basidiomata and key micromorphological characters of D. crystallinum are added, suggesting that the identity of all collections should be verified molecularly in future, especially those from wood of broadleaved trees in France. Consequently, the Boubínský prales sequences most likely represent the first sequence data of D. bialoviesense but currently representing a paratype of the recently described species D. Simultaneously, Boubínský prales collections clearly differ in their ITS rDNA region from the only published Dentipratulum sequence based on a collection from France, originally identified as D. The Boubínský prales collections agree with the Białowieża collection in macro- and micromorphological characters and ecology, namely their growth on decaying wood of Picea abies in natural forest. One collection from the type locality, Białowieża virgin forest in Poland, was used for morphological comparison. Accessible online (open acces) from: - Two recent records of the rare fungus Dentipratulum bialoviesense from Boubínský prales virgin forest in the Czech Republic were documented morphologically and molecularly.
