California Foraging Calendar 2026
11 wild edibles, ordered by when each one is actually recorded in California, across 7 different peak months. Built from 30,573 research grade observation records and corrected for how many people were outdoors. Identification is a job for a person with the specimen in hand.

Chicken of the woods in California, month by month
The chart opens on the adjusted series, which corrects for observer effort, and the toggle shows the raw counts you would get from the site itself. Where they disagree, the raw curve is usually reporting when people were outdoors rather than when the species was fruiting. See the underlying California records on iNaturalist.

Before you eat anything you found in California
This site publishes timing, not identification. It tells you when a species has historically been recorded in your state. It cannot tell you what you are holding, and nothing on it should be treated as permission to eat a wild mushroom.
CDC reports that approximately 7,500 poisonous mushroom ingestions were reported annually to poison control centers across the United States. Source.
This is not a theoretical caution. During November 2025 to March 2026, the California Poison Control System and California Department of Public Health responded to an outbreak of 39 cases of amatoxin mushroom poisoning in northern California, resulting in three liver transplantations and four deaths. This is the largest reported outbreak of mushroom-associated hepatotoxic poisoning in California history and the largest in the United States in several decades. Amatoxins are not denatured by cooking or other methods of food preparation. CDC, Morbidity and Mortality Weekly Report, May 28, 2026.
- “The public should be aware that poisonous mushrooms might resemble nonpoisonous mushrooms, cooking mushrooms does not remove or inactivate toxins, and that wild mushrooms should never be consumed unless they are identified by an expert.” CDC, Morbidity and Mortality Weekly Report, accidental poisonous mushroom ingestions, United States 2016 to 2018
- “Poisonous mushrooms often resemble and are difficult to distinguish visually from nonpoisonous, edible mushrooms.” CDC, Morbidity and Mortality Weekly Report, Amanita species mushroom poisonings, northern California, November 2025 to March 2026
- “Even people with years of experience picking wild mushrooms can sometimes mistake these toxic mushrooms for safe ones.” California Department of Public Health
- “Only an expert can differentiate between poisonous and edible mushrooms.” Penn State Extension
Where to take a question instead
- North American Mycological Association: Volunteer identification consultants, listed by state. NAMA keeps a state by state list of volunteers who will help identify a mushroom when a poisoning is suspected. It is a free service. This is the single most useful link on this page.
- Report a mushroom poisoning. “It is important to file a report, even if the outcome was only a gastrointestinal upset. NAMA tracks ALL mushroom poisonings.”
- Poison Control, 1-800-222-1222. One number covers the whole United States, around the clock. There is also an online triage tool. Both are free and confidential. poison.org
The single most useful thing on this page is not a date. It is NAMA’s list of volunteer identification consultants, which is organised by state and is free. Find the California entry before you need it rather than after.
Where you may legally gather in California
The rule is set by whoever manages the ground you are standing on. In several states the parks agency and the forests agency are different agencies with opposite rules, so these are given separately rather than as one line for California.
California state parks
Permitted only within stated limits or only where posted.
“No person shall willfully or negligently pick, dig up, cut, mutilate, destroy, injure, disturb, move, molest, burn, or carry away any tree or plant or portion thereof, including but not limited to leaf mold, flowers, foliage, berries, fruit, grass, turf, humus, shrubs, cones, and dead wood, except in specific units when authorization by the Department to take berries, or gather mushrooms, or gather pine cones, or collect driftwood is posted at the headquarters of the unit to which the authorization applies.”
California inverts the Oregon and Washington pattern. Nothing is gatherable by default; berries, mushrooms and cones become lawful only where a posting exists at that specific unit's headquarters. A separate subsection caps any allowed collecting at five pounds per day.
California state forests
Permitted only within stated limits or only where posted.
“Annual fruits of native plants such as gooseberries, elderberries and blackberries may be picked and empty conifer cones may be taken for non-commercial use.”
14 CCR 1416(b), demonstration state forests
Mushrooms are not in that list. Jackson Demonstration State Forest, for example, allows mushroom gathering only with a purchased permit.
Federal land in California follows its own rules regardless of the above. National Park Service units prohibit gathering plants by default under 36 CFR 2.1, with each superintendent free to designate fruits, berries and nuts for personal use, so the answer differs park by park. National forests generally allow small personal use quantities, but there is no national number: the threshold is set regionally, which is why neighbouring forests publish different limits. Private land needs the owner’s permission, and several states make taking plant material a separate offence from trespass. The full breakdown by land type is on the hub.
These are our readings of the cited regulations and are not legal advice. Regulations are amended, and the current rule of the specific park, forest or district you are standing in governs.

California foraging questions
Windows on this page are climatology derived from iNaturalist research grade observation records in California, not a forecast and not a map of where anything grows. Nothing here identifies a mushroom or states that anything is safe to eat. Take an identification question to a person: NAMA identification consultants or Poison Control on 1-800-222-1222.
