The paper presents data on new findings of aphyllophoroid fungi in the Nenets Autonomous Okrug. The studies have resulted in a 1.8-fold increase in the formerly available list: 28 species new to the region were added to the 35 species known previously. Additionally, Heteroradulum deglubens is reported for the first time for the Arkhangelsk Region. Information is provided on the substrates, habitat characteristics, dates of finding, ecological and morphological characteristics, geographical elements, and distribution of each species in the Arkhangelsk Region. Two species (Phellinus lundellii and Rhodofomes roseus) specific to old spruce and pine forests were encountered. The records include 21 species on deciduous wood, five species on conifers, and two species on the ground. Birch was the substrate for 11 species, alder and willow for five species each, spruce for four species, aspen for two, and juniper for one species. A predominant majority of the species are specialists of one substrate and are widely distributed in forest ecosystems of European Russia. Most of the species identified to date in the Nenets Autonomous Okrug are annual, circumglobal and Holarctic, and are hygrophilic and mesophilic in terms of the habitat moisture preferences.
