Panaeolina foenisecii is a very common and widely distributed little brown mushroom often found on lawns. It fruits in warm weather and does not contain the hallucinogen psilocybin despite several erroneous reports to the contrary. [1] In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-htp and 5-hydroxyindoleacetic acid.

It is sometimes mistaken for the hallucinogenic Panaeolus subbalteatus or Panaeolus castaneifolius which both share the same habitat and can be differentiated by their jet black spores.

• Gills: Broad, adnate, brown with lighter edges, becoming mottled as the spores mature.
• Spores: Walnut brown, 13 x 7 micrometers, finely roughened with an apical germ pore.
