This “Mushrooms for Color” website is sponsored by the International Mushroom Dye Institute (IMDI), founded by Miriam C. Rice in 1985. Miriam believed that people throughout the world would benefit from exploring the full spectrum of color derived from mushrooms.

The IMDI was established under IRS Code Section 501©(3) as a non-profit organization for educational purposes. All donations are tax-deductible to the extent as allowed by law.
