Panaeolina foenisecii, commonly called the mower's mushroom, haymaker or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns. It fruits in warm weather and contains the hallucinogen psilocybin.[1] In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-htp and 5-hydroxyindoleacetic acid.[citation needed]
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.

- Spores: Walnut brown, 13 x 7 micrometers, finely roughened with an apical germ pore.
