Skokomish Ridge Mushroom Growers’ Cooperative

Skokomish Ridge Mushroom Growers’ Cooperative and its individual grower members produce a variety of specialty mushrooms for distribution throughout the Olympic Peninsula and Puget Sound Region. Mushrooms currently grown include shiitake, maitake, lion’s mane and king trumpet. The Cooperative was established by Bob and Harriet Ames in 2016 who have over 12 years of experience in growing mushrooms.
The business concept was developed to eliminate most of the expense, administrative and technical aspects encountered by mushroom growers which prevent them from expanding their farm and realizing its full potential.
Grower members build their mushroom growing facilities on their own property with technical support from the Cooperative. Grower members purchase the mushroom production units (bags containing the sterilized substrate inoculated with the pure culture of the mushroom species to be grown) from the Cooperative at cost, and grow the mushrooms in their own grow rooms.


The Cooperative performs all the preparation and laboratory work for the growers and then purchases the mushrooms that the growers produce. The Cooperative also takes care of all the packaging, marketing, sales and distribution of the mushrooms thus eliminating these time-consuming functions from the grower. Our mushroom growers receive a payment for the mushrooms they produced each month as well as a bonus payment derived from surplus funds at the end of the year.
