The paper presents the first data on the findings of agaricoid fungi in the greenhouses of the Central Siberian Botanical Garden SB RAS. A total of 15 species of agaricoid basidiomycetes (Basidiomycota, Agaricomycetes, Agaricales) from 11 genera and 6 families were found in the greenhouse complexes of the botanical garden located in the Sovetsky district of the city of Novosibirsk. Half of the species belong to the family Agaricaceae, including some of lepiotaceous fungi known from warmer areas. All the identified species are saprotrophs, growing on soil and plant residues. Most of the species from the families Agaricaceae, Hymenogastraceae, Mycenaceae, Pluteaceae, Psathyrellaceae and Strophariaceae which were discovered in the greenhouse interiors of the Novosibirsk Botanical Garden were found in the natural forests of the surrounding areas, and were brought into the greenhouses, florariums, flower pots with substrate or fertilizer (soil, woody remains, bark, moss, manure). Only five species (Cystolepiota fumosifolia, Leucoagaricus americanus, Leucocoprinus brebissonii, L. straminellus and L. cepistipes) are specifically greenhouse species and were most likely introduced into the greenhouses of the Central Siberian Botanical Garden with planting materials of tropical plants. All of the species listed above are new for the Novosibirsk region. Cystolepiota fumosifolia is new for Siberia and Russian Federation. Of the 15 identified species of agaricoid fungi, Cystolepiota fumosifolia, Leucocoprinus cepistipes and L. brebissonii were the most common. The fruiting of Cystolepiota fumosifolia and other species found in the greenhouse soil of the demonstration greenhouses ceased after the greenhouse plants were transferred to another building. In the florarium, located in the greenhouse complex of the main building of Botanical Garden the fruiting of Leucocoprinus cepistipes is recorded annually in the winter.
