I have no idea where the claim that there's "no historical evidence for their use" comes from and would like to see a source (or just evidence that you've done any amount of research before making this claim). I think you might be confused because the term "hallucinogenic" only came of use around the 1950s For example, this paper[0] explores the ethnobotanic use of hallucinogenic mushrooms in Slovenia says > Use of hallucinogenic plants and fungi, believed to extend back thousands of years, is an important part of the human experience > The term hallucinogen first became popular in the 1950s and was originally used as the substances were said to produce hallucinations, though we now know that this is often not the case at lower doses Ancient Greeks drank psychoactive concoctions that contained a mix of psychedelic mushrooms and even reports from the Middle Ages document their use. Clusius (1525-1609), a physician and botanist, discovered ‘bolond gomba’, a mushroom known in Germany as Narrenschwamm or Fool's mushroom, which was used in rural areas to concoct a love potion. ‘Fools mushrooms’ were also documented around the same time in Slovakia, Poland, and in England [0] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7790546/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7790546/
