Clitocybe Dealbata indeholder så vidt jeg kan læse Muscarin, og muligvis andre alkaloider...
Umiddelbart, kan jeg ikke finde nogen referencer om at der er psilocybin/psilocin i den.
MuscarinCitat:
Ingestion of any number of Inocybe or Clitocybe species (e.g., Inocybe geophylla, Clitocybe dealbata) results in an illness characterized primarily by profuse sweating. This effect is caused by the presence in these mushrooms of high levels (3- 4%) of muscarine. Muscarine poisoning is characterized by increased salivation, perspiration, and lacrimation within 15 to 30 minutes after ingestion of the mushroom. With large doses, these symptoms may be followed by abdominal pain, severe nausea, diarrhea, blurred vision, and labored breathing. Intoxication generally subsides within 2 hours. Deaths are rare, but may result from cardiac or respiratory failure in severe cases.

Group V -- Muscarine Poisoning -- PSL Syndrome
It is a good idea to avoid eating little white or brown mushrooms that grow in the grass, since some members of two common genera, Clitocybe and Inocybe, contain significant amounts of muscarine.
This is a toxin that, within 30 minutes to 2 hours of being consumed, sends the exocrine glands -- the producers of sweat, saliva and tears -- into top gear in what is called the 'PSL' syndrome (perspiration, salivation, lachrymation), and also causes constriction of the pupils, blurred vision, muscle spasms, diarrhea, slow heartbeat, and a drop in blood pressure. The only real danger here is that the heart may actually stop, if enough toxin has been absorbed. This has happened only rarely, and then in patients with existing cardiovascular disease. The appropriate treatment is carefully administered intravenous atropine.
