Psilocybin mushrooms

Neutral information on mushroom species containing psilocybin and psilocin: legal status in Turkey, deadly look-alikes and emergencies. It does not recommend any use.

What are they?

These are mushrooms containing the substances psilocybin and psilocin. They do not belong to a single genus: species are reported in Psilocybe, Panaeolus, Gymnopilus, Inocybe and even Galerina. Most are small, brown and ordinary-looking, which makes telling them apart from deadly species by eye almost impossible. Clinical research is ongoing; that does not mean an approved treatment. [5]

Legal status in Turkey

  • Psilocybin and psilocin are listed in Schedule I of the UN 1971 Convention on Psychotropic Substances. [1]
  • Turkey signed the Convention on 21 February 1971 and ratified it on 1 April 1981. [2]
  • The Convention lists the active substances, not the mushrooms themselves; national practice can still treat the mushrooms as drugs. Dried mushrooms seized by Turkish customs in 2013 were officially described as a "psilocybin-type narcotic substance". [5][4]
  • Article 188 of the Turkish Penal Code covers manufacturing, importing, exporting, selling and possessing narcotic or stimulant substances; article 191 covers buying, accepting, possessing for use and using them. [3]

Why they are dangerous: deadly look-alikes

Psilocybe cyanescens Psilocybe cyanescensInedible · legally controlled Galerina marginata Galerina marginataDeadly poisonous

They can grow side by side on wood chips and rotting wood; this confusion has had fatal results. [6][7]

Psilocybe semilanceata Psilocybe semilanceataInedible · legally controlled Inosperma erubescens Inosperma erubescensDeadly poisonous

Little brown grassland mushrooms are confused with muscarine-containing Inocybe species. [8]

If poisoning is suspected

  • The deadly galerina contains amatoxins: symptoms start hours later with vomiting and diarrhoea, the liver is badly damaged and it is fatal if untreated. [7]
  • Some species in the Inocybe group contain a possibly fatal dose of muscarine; hospitals treat it with antidotes such as atropine. [8]
  • If vomiting, diarrhoea, altered consciousness or weakness follow eating any wild mushroom, do not wait for it to pass: call 112, contact the Turkish poison centre on 114 and keep any leftover mushroom.
