Oh Looky What I found!
The IAMSHAMAN-online shop sells a Lichen it claims to be Psychedelic:
Check it out.
Anything to back that up?

An unidentified saxicolous lichen was called Jievut hiawsik [lit. "Earth flower"] by the Pima of California. It was used as a good luck charm, and it was smoked for its narcotic effect (Curtin 1949)."

LICHEN
Common name: Lichen on stones
Pima name: Jievut hiawsik

As no specimens could be procured, I was unable to obtain the botanical identification of lichen. However, I learned that "earth flower" is the translation of both the Pima and the Papago name.

Mary Manuel introduced the subject by saying: "Men know more about this than I. The Pima men gather jievut hiawsik and carry it in their pockets to bring luck in killing game. The Maricopa are too superstitious to do that, for they fear if they carry the plant about too much, it will make them sick."
This lichen, which has a strong odor, is the color of grey ashes and grows on rocks and dead wood in certain spots on the hills. It has more religious meaning than any other plant, and is smoked, mixed with tobacco, at the summer dances, when its distinctive odor is noticeable. Like marihuana, the smoking of jievut hiawsik "makes young men crazy." "The Pima believe that if they smoke this lichen they can get any woman they want, but this is just a superstition," explained George Webb.

Isaac Howard described "earth flower" as being "reddish and white and different colors, and smells like violets." He says the lichen is ground into a powder which is not bound on sores or cuts, as it would produce blisters, but is sprinkled on the affected parts. Isaac told of a case where a girl, struck by a rattlesnake, was taken to a hospital and the wound was lanced by a doctor. As it did not heal, she returned home and my informant cured the wound by using the above remedy four times at intervals of several days. Another treatment, related by Mary Manuel, is to apply red coals, when the swelling begins, on wounds caused by snakes, scorpions, and black-widow spiders.

A. Shulgin wrote about this in PIHKAL. The chemicals in some lichens can react with essential oils in some natural products (i think he used orange juice as the example) to make synthetic THC:

THC and Lichens

Dear Dr. Shulgin:

In PIHKAL you have mentioned that the chemicals obtained from lichens can easily be brought to react with certain essential oils from natural sources, to make synthetic tetrahydrocannabinol. Are there more detailed references to this process beyond what is in your book? –Tengu

Dear Tengu:

There certainly are! The tetrahydrocannabinol molecule from Cannabis can be viewed as a combination of two very different halves.

The right half (as the structure is usually drawn) resembles the nucleus of many of the substituted benzene-ring containing components found throughout the lichen world. Isolation of these products can give the raw materials that can be converted to the compound olivetol, a simple amyl-substituted resorcinol compound.

The left half is a terpene which contains ten carbon atoms, and which is substantially identical to the essential oil, pulegone. This component makes up some 80 to 90% of the Oil of Pennyroyal.

The fusion of these two materials has been shown (Claussen et al., Tetrahedron Vol. 24 p. 2879 (196), to produce several products, one of which is delta-3-THC. This is a close structural isomer of delta-9-THC, the principal active component of marijuana, and is known to be active in man.

"Stoned on Stones"

"It was the most intense hallucinogenic experience that I've ever had, and I've done every trip there is," says Icelandic writer Smari Einarsson. "DMT, peyote...you name it. We have these magic mushrooms here that grow wild. I've eaten those more times thank I can count. They cannot even come close to the effect of these rocks." Volcanic rocks, which cover the Icelandic landscape, have been getting local kids high for five years now, ever since a local artist did a performance piece called Rock Soup. Jon Sigmundson's art piece was meant to make a commentary on Icelanders' high standard of living, which he believes relies on taking for granted third-world suffering. He made rock soup, he said in a written statement, to "try and live on nothing." The serendiptous discovery he made is that these rocks get you fuggin' wasted.

It is actually the lichen that lives on the rocks that gets you off. You take a few stones, boil them in a pot of water, strain it all through a colander, and drink it down like tea. Some people add ginger and honey, but it has a nice taste undiluted. It's very earthy. People who have "taken stones," as it's called, share strikingly similar stories. "Trolls," says a young Icelandic girl who was interviewed at local Reykjavik bar Sirkus.She'll only give her first name, which is Essa. "Every time we do stones, we see the same group of trolls. They are no unkind, but they aren't overly friendly either," she says. "Mostly what they do is advise you. You always come away from a stones trip with a question that you had on your mind answered. You also the most vivd colors ever. It's like living in Fantasia!"

A novel species of Dictyonema was used by the Waorani as a hallucinogen. They called the lichen Ne/ne/ndape/ and used it in shamanistic rituals (Davis and Yost 1983).

Area: Eastern Ecuador
Notes: last used ca. 1900, but formerly used in shamanistic ritual. Caused severe headaches and confusion. Very rare.

Chew-Z, anyone?

Everyone seems to have some pretense of being an artist in this hipster oasis, complete with palm-tree murals in the courtyard and a knowingly kitsch, retro interior. DJs 3 nights a week play an eclectic mix of pop, indie, salsa, techno, and metal, and you can expect a line after 1am. Look out for their annual Tom Selleck moustache competition.
