HBMS Membership

The purpose of the Humboldt Bay Mycological Society is to promote the enjoyment and appreciation of wild mushrooms through study and the exchange of information. Everyone who has an interest in wild mushrooms is welcome to become a HBMS member.

Your membership supports our nonprofit with scholarships, travel costs and honoraria for speakers, rental fees, initial fair costs, and hopefully even more as our membership grows! While our meetings from September-January are open and free to all, as a member you also get:

• The HBMS email newsletter in April & September-January.

• Free participation in members-only field trips & events

• Pre-registration for HBMS workshops

• Discount codes for events and merch

• Free and early entry to the Annual Mushroom Fair (Family memberships gets your whole family in for free!)

• Advanced ordering on fair merchandise

• To support the HBMS – our existence depends on your membership

Memberships renew each January and cost $15 for individuals, $20 for families, and $10 for students and seniors.
Lifetime membership is $185 for an individual and $240 for a family.
