Hericium erinaceus (Lion's mane mushroom) has isolates called Hericenones and Erinacine that promote nerve growth factor synthesis and a lot of other Neurohealth benifits being found to do with the compounds the fungi produces.
Protip: If/When buying supplements -- There's many that are just selling capsules of ground myceliated brf (brown rice flour - the substrate inoculated/grown on). Mycelium is the 'roots/pre fruiting stage' of the fungi -- The fruit body/ mushroom itself has much greater concentrations of the desired compounds.
