Cave murals found in Spain appear to depict them in religious rituals - which would be the oldest evidence of their use in Europe.
The Selva Pascuala cave mural near the town of Villar del Humo has a bull in the centre, but researchers from America and Mexico are focussing on a row of 13 small mushroom-like objects.
Brian Akers at Pasco-Hernando Community College in Florida, and Gaston Guzman at the Ecological Institute of Xalapa in Mexico say they believe the objects are Psilocybe hispanica, a local funghi with hallucinogenic properties.
The mushroom has a bell-shaped cap with a dome and lacks a ring around the stalk, just like the objects in the 6,000 year-old mural, they say.
It also has stalks which vary from straight to sinuous - the same as those drawn thousands of years ago, they add in the latest issue of New Scientist.
But, even though it is several millennia old, it is not thought to be the oldest painting showing hallucinogenic mushrooms.

Just last month, it was revealed the Chauvet-Pont-d'Arc Cave in southern France is to be the subject of a 3D documentary by German filmmaker Werner Herzog, as it is thought to be where man made his first attempts to write.
Since its (re)discovery in 1994, the cave in southern France has offered scientists a veritable treasure trove of perfectly preserved paintings.
Alongside these are evidence of attempts at communication 30,000 to 40,000 years ago.
I have walked on water. So it appeared after drinking a cup of mushroom tea for the first time several years ago. As I was walking down a paved driveway wondering what it was I was suppose to experience from these shrooms I suddenly noticed that the road turned to water. I had to keep touching it to make sure it was not real. It was then that I had an epiphany...The Days of Antiquity were most likely filled with mind altering substances that were enjoyed my many people. I thought of Jesus and his flaming red eyes realizing that he was high on Opiates or THC...both substances that definitely place one in an euphoric existence and a closer relationship to the consciouness and spirit (Allah). Then there is Moses and the many illusions he possessed. Check out this link: [Link]
These substances, through education could definitely save the world from the state that it is currently in and rescue the poor souls who have been brainwashed by religious institutional interpretation The Bible is filled with Hallucinations.
I bet the Mayans had a ritual of using mind altering substances.
To think that Christianity and Islam arose from drug induced scrolls. Look at what these institutions are doing to people and our world when the true savior lies waiting in a pasture somewhere.
Behold! For the Agave spun to life and decayed before my sight and I became weary as The Lord laid me to sleep. From the sky they descended penetrating my mind.
