Wisconsin Foraging Calendar 2026

In October, the species inside their typical Wisconsin window are black walnut, chicken of the woods, hen of the woods, giant puffball. Those windows come from 7,348 research grade observation records in Wisconsin, corrected for how many people were out recording. They describe when each species has historically been found here, not what is out there this week.

Apr 1 to May 31 in Wisconsin, peaking around May 15. That is derived from 585 research grade records of Morchella in Wisconsin, adjusted for observer effort. It moves year to year with spring: the live panel on this page reads the USA National Phenology Network Spring Index at three points in Wisconsin and tells you whether leaf out is running ahead of or behind its 30 year average this year, which is the best available signal for whether the morel window will be early or late.

Yes, within limits. Wis. Admin. Code NR 45.04(1s)(a)1, as stated by Wisconsin DNR states: "Edible fruits, edible nuts, wild mushrooms, wild asparagus and watercress may be removed by hand without a permit for the purpose of personal consumption by the collector.". The same DNR page states that collection of seeds, roots or other plant parts is prohibited. The rule covers all DNR lands rather than parks and forests separately. Note that Wisconsin state forests may be governed by a different agency under a different rule, which is covered separately on this page. This is our reading of the regulation and not legal advice.

Not from this page. This is a timing site; identification is a job for a person with the specimen. CDC states that poisonous mushrooms often resemble and are difficult to distinguish visually from nonpoisonous, edible mushrooms, and that cooking does not remove or inactivate the toxins. Take it to a person: the North American Mycological Association keeps a free list of volunteer identification consultants organised by state, and Poison Control is on 1-800-222-1222 around the clock. Where a species on this page has a lookalike that authorities name, the lookalike is named and identification is left to a person.

Because most of them are folklore copied between websites, and these are derived from records. Two corrections in particular move the dates. Counts are divided by the total observations of everything in Wisconsin in the same month, which removes the effect of how many people happened to be outdoors; that shifts the peak month for about a quarter of the species on this site. And fruit and nut species are counted only from records an observer annotated as fruiting, because a raw count of a plant peaks when the plant is most photogenic rather than when it is ripe. Elderberry raw counts peak with the flowers, two months before there is fruit.

For the spring species, yes, and the panel at the top of this page measures it. It reads the USA National Phenology Network Spring Index First Leaf surface for three points in Wisconsin and compares this year against the 1991 to 2020 average, giving the shift in days. In Wisconsin that applies to ramps, morel, oyster mushroom. It does not apply to the autumn mushrooms, which fruit on late summer and autumn rainfall rather than on spring warmth.

Sep 1 to Nov 1 in Wisconsin. Harvest licence required, and harvest is banned on all state land. American ginseng is listed on Appendix II of CITES, and the US Fish and Wildlife Service states that harvest is illegal on most state lands, all National Park Service land, and all national wildlife refuges, and is prohibited in most national forests. Ginseng is not on the calendar on this page and we are not encouraging you to dig it; the dates are here because the question gets asked and is widely mis-stated.
