The Panaeolus grows best in early spring and autumn. The mushroom is common in Europe but also found in the tropics and subtropics (Asia and America). The mushroom grows in a humid environment and prefers field fertilized with (horse) manure. The Panaeolus subbalteatus is initially moist and brown, but fades in the center when it dries. That’s why the common name of the Panaeolus subbalteatus is “dark-rimmed Mottlegill’. The mushroom starts growing with a somewhat convex cap, but quickly becomes plane. The cap of the Panaeolus subbalteatus is mostly 2 to 6 cm in diameter. There are now traditional uses of this mushroom known in West European history.
The Panaeolus subbalteatus contains approximately 0,7% psilocybin and 0,46% baeocystin along with large amounts of serotonin and 5-hydroxytryptophan. It does not contain psilocin. Experimental research demonstrates that serotonin can not reach the brain when taken orally. Nevertheless, the trip reports of the Panaeolus subbalteatus are different from mushrooms that contain only psilocybin; they are more empathogenic and aphrodisiac and yet still very hallucinating.
