Panaeolina is a small genus of small mushrooms, containing only about four species. They are a subgroup of Panaeolus which have dark brown spores. The type species is Panaeolina foenisecii, a common lawn mushroom. Members of ''Panaeolina'' are broadly distributed throughout the world. Some members of Panaeolina have been reported to contain the hallucinogen psilocybin, however these results are thought to be false positives.〔(【引用サイトリンク】 title=Observations Regarding the Suspected Psychoactive Properties of Panaeolus foenisecii Maire )〕 These fungi are sometimes classified as part of the genus ''Panaeolus''.〔See (Mushroom expert page on ''Panaeolus foenisecii'' ), which gives further references which use both these naming choices.〕 Like that genus their gills have a cloudy/speckled/mottled appearance due to the way that their spores ripen unevenly in spots, but they are distinguished because the spores are ornamented while those of ''Panaeolus'' (in the restricted sense) are smooth. Also their gills are dark brown, instead of black or grey.〔Courtecuisse, R. & Duhem, B.
