Field trips and forays are lead by more experienced members to various locations in the Bay Area and around Northern California, and offer opportunities to learn more about mushrooms, to safely collect and eat mushrooms, and to enjoy good company. Forays are attended by many types of people with the connecting element being an interest and curiosity about our fungal friends. Some events are open to all, and some are MSSF member-only. See the the event calendar for forthcoming forays and the collecting equipment list for suggested items to bring on forays.

Fall 2020 - Spring 2021

Forays will be conducted on various dates between 1 November 2020, and 28 February 2021. Announcements of foray dates will be made approximately one week prior to the scheduled dates of the forays by general e-mail announcements to all MSSF members.

Forays will consist of: local, day trip, and quick start forays. All forays will be dependent upon receiving sufficient moisture, (rain) prior to the forays.

All forays, regardless of location will be conducted in accordance with the San Francisco Coronavirus, (Covid-19) health directives. This requires that all small outdoor gatherings consist of 12 people or less, (including the leader/s), be two hours or less in duration, and that all participants be screened 24 hours prior to a scheduled foray, (Questionnaire). All participants must have hand sanitizer, their own water container, and wear face coverings at all times during the foray.

Carpooling to foray locations is only recommended with members of the same household. It is strongly recommended that you have received this year's flu vaccination before attending a foray.

Forays will be posted on the MSSF website, event registration page approximately one week before the scheduled foray dates. All forays will be first-come, first-served for members in good standing with dues paid up-to-date. NO GUESTS will be allowed, and only two adult members from each household will be allowed to sign up. There will be no standby waiting list for these forays.

General information about types of forays organized by MSSF.
Due to COVID, we are not scheduling any of the campout-type forays for the foreseeable future.


Local forays are often to a county or regional park, within a short drive of San Francisco, start about 9:00 am with a walk with the leader, who will help with mushroom identification and interpretation, and answer questions. Collection may or may not be allowed at these locations.

Day trips

Day trips are to locations that allow collecting, start a 9:00 am and often are a mix of more experienced forayers and newbies. They have a more loose structure, with the more experienced individuals wondering more widely. Beginners can walk with the leader or with one of the more experienced forayers. Interpretation includes insights by the leader as well as experienced participants.

We walk, break for lunch break in the field, then collect until 2:00 or 3:00. The group returns to the starting point, and review the collections.

Quick start forays

Quick start forays are new, it is announced on the MSSF Mailing List and MSSF online calendar only a few days before the event. Location and time are up to the event initiator. These allow us to react to changing conditions or reports of good fruiting.

Car camping forays

Car Camping forays involve the leader selecting an overnight camping location, a campground or primitive camp spot. We meet Saturday morning at 9:00 am and then drive or walk to the foray location. The foray is an all day event, with lunch in the field and returning for dinner. The participants create a potluck meal, hopefully with mushroom finds from day, or personally crafted dishes. Usually a fire and an exchange of elaborate tales of glory—mushrooms found that day or in the past—ensues.

Sunday there may be a potluck breakfast and forayers are free to explore nearby terrain to put to use the knowledge gained over the course of the foray.

Fungus Fair collecting forays

Fungus Fair collecting forays are on the day before the fair. The various leaders meet small groups of volunteers at locations where collecting is permitted. Mushrooms are collected to represent the local mycota that are in condition to display at the fair. Collections are returned to the fair site at or before 5:00pm for identification and placement on the display tables.
