Summary ²

Panaeolus 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. In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-HTP and 5-hydroxyindoleacetic acid. In many field guides it is erroneously listed as psychoactive, however the mushroom does not produce any hallucingenic effects.
