Panaeolina Foensecii 20110625 Detail
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. These fungi are sometimes classified as part of the genus ''Panaeolus''.SeMushroom 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. (1994) "Guide des champi ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ...
