The IMDI was created by Miriam C. Rice in 1985 to encourage the use of Fungal Pigments; to further research on their extraction and employment; to encourage research and cultivation of dye fungi; to financially assist artists and researchers to participate in the international symposia and exhibitions.

Read about Miriam C. Rice, the mother of mushroom dyes, and rediscover her remarkable history and artwork!

" Miriam's door was always open to her ever-widening circle of friends of all ages. Artists and seekers, poets and writers, environmentalists and leftists found stimulating conversation and a smorgasbord of experimental culinary treats at her table. She was an intelligent, inquiring earth sprite and creative alchemist with a pot bubbling on the back of the stove at all times." (by Felicia Rice)



The SOMA Fiber Arts program was introduced by Miriam C. Rice at the very first SOMA Camp held at the old soccer camp in Mendocino County in 1998. Miriam shared her groundbreaking research in creating natural dyes from mushrooms with fascinated campers!

In 1999, Miriam introduced" Papermaking with Polypores " to complement the mushoom dyes at the 1999 SOMA Camp held At "Wellsprings" in Philo, CA.

"Making Myco-Stix'' (wax crayons with fungal pigments) were taught by Miriam at SOMA Camp held at the Boys Scout Camp in Navarro, CA in 2004 (or was it 2005?) . So now we had mushroom "myco-stix' to draw on our "polypore paper!

Over succeeding years of SOMA Camp, some of Miriam's former fiber students and assistants took on the teaching of workshops in fungal fiber arts, adding classes in felting, eco-printing, Shibori, basket weaving, lichen dyeing, and more. Some of the photo memories of those classes may be viewed here:

The exhibit is part of a Mycology display presented by the exciting new Mendocino Coast Mushroom Club recently formed in Mendocino County, CA and will be on view throughout November and December 2019!





Proceeds from the sale of this video will benefit the travel grant program of the The International Mushroom Dye Institute (IMDI), to financially assist fiber/fungi artists and researchers to participate in future International Fungi & Fibre Symposia!

The 2018 IMDI Travel Grant was presented to Liza Johansson of Sweden!


Miriam C. Rice's amazing book,
"Mushrooms for Dyes, Paper, Pigments
& Myco-Stix"

long out of print, has just been reprinted by the IMDI, and is now available to order directly from Fungi Perfecti

They say the apple does not fall far from the tree!

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