Mycobiota of the planned protected area Nyuk Lake (Republic of Karelia, Russia)

The article reports the results of macrofungi surveys in the planned protected area Lake Nyuk (pPA), situated in the north-west of the Republic of Karelia. The forests there are primarily north-boreal pine stands with pine trees aged 170—250 years at maximum. As of now, records from the pPA include 183 species of 114 genera of aphyllophoroid and agaricoid fungi. The annotation for each species specifies their habitats and occurrence. Seven species are reported for the biogeographical province Karelia pomorica occidentalis for the first time; of which two species, Hydnellum gracilipes and Tubulicrinis medius, are first records for the Republic of Karelia. The territory was found to harbor nine fungal species (Anthoporia albobrunnea, Diplomitoporus crustulinus, Flavidoporia mellita, Gloeophyllum protractum, Resinoporia crassa, Rhodonia placenta, Sidera lenis, Skeletocutis sajanensis, S. stellae) red-listed in the Republic of Karelia (2020). Locations of 13 indicator species and 16 specialist species of biologically valuable forests are known within the pPA. The findings are validated by the herbarium specimens stored at the Karelian Research Centre RAS Herbarium (PTZ) and Botanical Museum of the University of Helsinki (H). The rationale for establishing a nature conservation area in the territory is provided.
