This article presents a list of aphyllophoroid fungi species in the Kenozersky National Park, located in the Kargopol and Plesetsk Districts of the Arkhangelsk Region. The list numbers 247 species, including five species (Athelia neuhoffii, Climacodon pulcherrimus, Peniophora pini, Phanerodontia magnolia, and Tomentella punicea) found in the area only within the Park. The park harbors 16 species listed in the Red Data Book of the Arkhangelsk Region (2020), as well as 20 indicator species old-growth spruce and pine forests, and 5 of pristine spruce and pine forests. Fifty-three species were encountered on spruce wood, 45 on pine, 26 on juniper, 8 on larch, 76 on birch, 68 on aspen, 44 on willow, 42 on alder, 14 on bird cherry, and 10 on rowan. Eighteen species occurred on soil, 10 on fruiting bodies, and 1 species on cones. Among the records, 59.1 % were confined to a single substrate, 51 species were sampled from two tree species, 29 from three, 15 from four, and 3 from five. Xylodon radula was found on six tree species, and Botryobasidium isabellinum and Fomitopsis pinicola were found on seven. The vast majority of species are widespread in forest ecosystems of European Russia. The presence of a number of rare, endangered, and regionally endangered fungal species within the national park makes its forests unique, highly valuable, and unparalleled in the region.
