Processing: many fungi are extremely tough; however, they must be chopped up to release their pigment in the dyebath. If the bracket is extremely hard, soak it in water to cover for one to three days, or until you can easily dent the surface with your nail. Most bracket or shelf fungi are light in weight, so you may have to put a brick on top of them. If you use a rock to weigh the fungi down, be aware that the mineral content of that rock in the water may affect the colour of the resulting dyebath. If the fungi does not soften after it is soaked, try pouring boiling water over it, or heat it up in the dyepot whole, just as it is. Let it simmer for an hour, cool it, and then try to cut it up. Save this water as the dyebath, and add the cut-up fungi to it.
Colours obtained: yellow, beige, tan, greyish-yellow, light brown, gold – most fungi give these shades. I obtained a dark brown from Ganoderma which was chopped up and soaked out for two weeks. The smell was unpleasant, but the fibre dyed an interesting shade. However, the colour faded after several weeks’ exposure to light. All types of fungi are interesting to work with and warrant further investigation as potential dyestuffs
