On our trip to Lazarim, my eye caught trees covered in with lichens (a fungus). This post immediately came to mind and we stopped the car to pick up a bag full. Two days later the lichens were tossed into a pan and boiled for about an hour, after which I stained the water, put a piece of white linen and boiled slowly for about another hour. It led out a strong earthy smell. I did this rather instinctively, without a mordant and without much knowledge of textile dyeing techniques, so the piece of linen came out in a raw beige color.

What I'm really looking for is a way to dye linen in greys and blues! I bought some potassium ferricyanide crystals or Prussian Blue, (it's the blue in the cyanotype process), but I haven't found much information on it's ability to dye textiles. I think I'll just do the same: toss it in a pot and see what comes out!
