Tuareg blue: For the Tuareg, the colour blue really does run skin deep. Due to the lack of water in the Sahara, they use powdered indigo to dye their robes. The dye however, has a tendency to bleed onto the skin of its wearer when subjected to desert temperatures. Years of wearing these indigo-dyed fabrics can cause their skin to become permanently stained dark blue.
Fomes fomentarius Fomes fomentarius - Iceman fungus, hoof fungus, amadou etc. Medicinal, used to carry fire, makes hats, cloth etc. Pretty funky looking. It is perennial growing new pore layers each year. If you cut it in half lengthwise you could see how old it is by counting layers. Much thanks to David Spahr for identifying this mushroom. mushroom-collecting.com/
