Some members of Panaeolina have been reported to contain the hallucinogen psilocybin, however these results are false positives.

These fungi are sometimes classified as part of the genus Panaeolus.^[1] Like that genus their gills have a cloudy/speckled 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. ^[2]
