Summary: the mushroom Lanmaoa asiatica makes careless eaters see little people using toxins which other shrooms haven't discovered.

"Biosynthetic gene mining of the L. asiatica genome found no close hits with any genes known in the production of mushroom psychoactive compounds," write the researchers in their published paper.

"This supports our hypothesis of the presence of a novel unidentified metabolite responsible for the unique hallucinogenic properties of L. asiatica."
