In 2019 and 2020 from May to October the known populations of rare species of Novosibirsk oblast were monitored; the biota of macromycetes of Moshkovskyi and Bolotinskyi districts was studied at the same time. As a result, new habitats of several rare species of agaricoid and gasteroid basidiomycetes were discovered. The article presents new data on 4 rare species of agaricoid and gasteroid basidiomycetes, included in the Red Data Book of Novosibirsk region: Melanophyllum haematospermum (Bull.) Kreisel, Pluteus fenzlii (Schulzer) Corriol et P.-A. Moreau, Phallus impudicus L. and Mutinus ravenelii (Berk. et M.A. Curtis) E. Fisch. Specimens are deposited in the M.G. Popov Herbarium (NSK) at the Central Siberian Botanical Garden of the Siberian branch of the Russian Academy of Sciences. The state of local populations of the identified species, the tendency of their distribution in the region and in the world, peculiarities of ecology and biology are discussed, and threatening factors are noted. A map with the locations of these species in the Novosibirsk region is presented. The obtained data confirms the rare status for the species Melanophyllum haematospermum and Pluteus fenzlii that belong to agaricoid basidiomycetes and still have low numbers of populations. Additionally, a new habitat for Pluteus fenzlii was recorded in the forests from the wildfire zone. In order to clarify the taxonomic and conservation status of the gasteromycetes Phallus impudicus и Mutinus ravenelii, molecular and DNA testing is required as well as further monitoring. At the present time, new habitats have been found for Phallus impudicus but the population numbers remain low. Conversely, fruit bodies of Mutinus ravenelii appear frequently, with the majority of new habitats found in the anthropogenic zone. The species is likely to be excluded from the list of rare species of Novosibirsk oblast.
