Lichens are not just fun guys.

Lichen: The Fungus Meets the Alga. Beatrix Potter was an early proponent of this symbiotic life form. Once thought to be scabs of the gods, lichens can survive exposure in outer space and British churchyards. They can be antibiotic, hallucinogenic, reindeer food, and when steeped in urine make great dyes for tartans and tweeds. In the words of Henry David Thoreau, "The beauty of lichens, with their scalloped leaves, the small attractive fields, the crinkled edge! I could study a single piece for hours. How they flourish! I sympathize with their growth."

and 2003 but here are some different links.

Oops on the Beatrix Potter link, everybody just add an "h" to to the front of what I was trying to do there.

Thanks Pollomacho and honest knave, I was inspired by the Livingstones. I enjoy sunning myself on rocks and once sang a song about being a lichen to the tune of "I'm a little teapot". I am quite conveniently forgetting the lyrics right about now.

and a mention of a mefite:
" The top of this lichen has a hard surface called a cortex"

Can also in a pinch be eaten by people. Survival TV personality Ray Mears showed the recipe during his heavy water sabotage reenactment.

Love that first link: "Mr. Fungus", that's priceless. And "Lichenland"... isn't that somewhere south of Munich?

Lichen are pretty cool - I was briefly involved with trying to clone out antibiotic-producing genes from various lichen.

Or were you talking about Lichen?

I still think plate fungus is better.

A friend's father spent a good portion of his career developing spray-on lichen spores for beautifying highway overpasses. Don't know what became of that. It was and is deployed somewhere I think, the problem was that it only took on the north side or something.

Lichen is an excellent indicator of air pollution. If you see lichen, it means your air is relatively clean.

I believe that's a somewhat hazardous occupation.

That is so bitchin'! The very idea of it, let alone that someone could make a career of it.

Several of the heavy water sabotage guys are still alive, 60 years later. Last year my (reserve, Norwegian armed forces) hosted a speak by Poulsson. Not often I meet a legend.

The key to eating that particular kind of lichen is to get the acidity down. The saboteurs used ashes and boiled them them for a long time. Ray Mears "cheated" with baking soda.
