Information about distribution of three species of gasteromycetes listed in the Red Data Book of Ukraine, Clathrus ruber P.Micheli ex Pers., Mutinus ravenelii (Berk. & M.A.Curtis) E.Fisch., and Pseudocolus fusiformis (E.Fisch.) Lloyd (Phallales, Basidiomycota), is given. Undoubtedly, these fungi are alien species in Ukraine. Almost all findings of Clathrus ruber are reported in Crimea, especially in the Nikita Botanical Garden and adjacent areas. Most often, the fungus occurs in broadleaf and mixed forests, old parks or forest park areas. Every year the number of records of this fungus increases, it is actively spreading on the South Coast of Crimea. In addition, in 2017 C. ruber was found in Ivano-Frankivsk Region. Until 2009, M. ravenelii was recorded only in Volyn and Rivne regions. Now localities of this species are known in Ivano-Frankivsk, Khmelnytskyi, Kyiv, Lviv, Transcarpathian, and Zhytomyr regions, and in Kyiv city. The habitats of the fungus are mainly associated with anthropogenically transformed territories, but it can also occur in natural plant communities, especially along footpaths, on canal banks, etc. Pseudocolus fusiformis in Ukraine was recorded only once, in the Nikita Botanical Garden. Information on another record of this fungus from the Ukrainian Roztocze seems rather dubious. Taking into account that C. ruber, M. ravenelii and P. fusiformis are not native in Ukraine, it is proposed to exclude (delist) these species from the Red Data Book of Ukraine.
