|Panaeolina foenisecii (Persoon) Maire
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.
These fungi are sometimes classified as part of the genus Panaeolus. 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.
