Mushrooms can be used to create color dyes via color-extraction with a solvent (often ammonia) as well as particulation of raw material.
[1] The shingled hedgehog mushroom and related species contain blue-green pigments, which are used for dyeing wool in Norway.
[2] The fruiting body of Hydnellum peckii can be used to produce a beige color when no mordant is used, and shades of blue or green depending on the mordant added.
[3] Phaeolus schweinitzii produces green, yellow, gold, or brown colors, depending on the material dyed and the mordant used.
