In season in Ohio in October

Chicken of the woods

LaetiporusFungusIn season now

Aug 1 to Oct 31, peaking around Sep 15

Built from 3,647 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

The documented hazard here is the species itself rather than a lookalike. Florida IFAS Extension states that raw or undercooked Laetiporus has been reported to cause gastrointestinal problems and that at least some individuals are allergic to it. Missouri notes swollen lips and stomach upset in some people even after cooking. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

American persimmon

Diospyros virginianaPlant, fruitIn season now

Oct 1 to Nov 30, peaking around Oct 15

Built from 161 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

The documented issue with persimmons is mechanical rather than toxic: tannin in unripe fruit can precipitate in stomach acid and form an obstructing mass. Every clinical report we could find concerns the Asian persimmon rather than the American one, so this is a genus level mechanism and not a documented American persimmon case. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Black walnut

Juglans nigraPlant, fruitIn season now

Sep 1 to Oct 31, peaking around Oct 15

Built from 169 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

The husks stain skin and clothing persistently and can irritate, which is a nuisance rather than a poisoning. We found no authoritative toxic lookalike pairing. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Giant puffball

Calvatia giganteaFungusIn season now

Oct 1 to Oct 31, peaking around Oct 15

Built from 618 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Named lookalikes: Destroying angel and other Amanita species, at the immature button stage. This is the most consequential pairing on the whole calendar. A deadly Amanita begins life as an egg shaped button that can be mistaken for a small puffball. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Hen of the woods

Grifola frondosaFungusIn season now

Oct 1 to Oct 31, peaking around Oct 15

Built from 581 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Missouri states that hen of the woods has no poisonous lookalikes, and that the similar pore fungi are tough and inedible rather than toxic. Berkeley's polypore, often described elsewhere as a dangerous lookalike, is itself listed as edible when young. That is a statement about Missouri's fungi, not clearance to eat anything you have not had identified. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Wild grape

VitisPlant, fruitIn season now

Sep 1 to Oct 31, peaking around Oct 15

Built from 43 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

Named lookalikes: Canada moonseed (Menispermum canadense). Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Lion's mane

Hericium erinaceusFungusIn season now

Oct 1 to Dec 31, peaking around Nov 15

Built from 291 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

The species Missouri names as similar, comb tooth and hedgehog, are themselves edible rather than poisonous. Missouri still adds: always be cautious when eating edible mushrooms. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Morel

MorchellaFungusspring

Apr 1 to Apr 30, peaking around Apr 15

Built from 1,129 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Named lookalikes: False morels (Gyromitra species); Verpa species. Michigan health authorities also note that true morels can make people ill if eaten raw, undercooked, in large quantity, or with alcohol, and that sensitivity can develop in someone who has eaten them for years without trouble. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Ramps

Allium tricoccumPlant, leafspring

Mar 1 to Apr 30, peaking around Apr 15

Built from 1,874 research grade records in Ohio, counted as recorded, because ramps are photographed when the leaves are up, which is the harvest window.

Named lookalikes: American false hellebore (Veratrum viride); Lily of the valley (Convallaria majalis). Vermont health officials issued this warning specifically because false hellebore comes up at the same time and in the same ground as ramps. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Oyster mushroom

PleurotusFungusspring

May 1 to Aug 31, peaking around May 15

Built from 3,408 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Missouri states there are no lookalikes in Missouri that are poisonous, and that most species misidentified as oyster mushrooms are woody or unpleasant rather than dangerous. That statement is scoped to one state. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Black raspberry

Rubus occidentalisPlant, fruitsummer

Jun 1 to Jun 30, peaking around Jun 15

Built from 120 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

Illinois Extension writes that there are no poisonous lookalikes to worry about among the brambles. That is a single extension article rather than a body of guidance, so we attribute it to Illinois Extension rather than asserting it ourselves. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Black trumpet

CraterellusFungussummer

Jun 1 to Sep 30, peaking around Jul 15

Built from 141 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Missouri states there are no lookalikes in Missouri, and immediately adds that you should be absolutely sure of the identification and eat only a small amount the first time. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Chanterelle

CantharellusFungussummer

Jul 1 to Aug 31, peaking around Jul 15

Built from 554 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

Named lookalikes: Jack-o'-lantern (Omphalotus illudens); Big laughing gym (Gymnopilus spectabilis). Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Wild blackberry

Rubus subgenus RubusPlant, fruitsummer

Jul 1 to Jul 31, peaking around Jul 15

Built from 136 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

Illinois Extension writes that there are no poisonous lookalikes to worry about among the brambles.

American elderberry

Sambucus canadensisPlant, fruitsummer

Jul 1 to Aug 31, peaking around Aug 15

Built from 396 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

Named lookalikes: Water hemlock (Cicuta maculata) and poison hemlock (Conium maculatum); Pokeweed (Phytolacca americana); Devil's walking stick (Aralia spinosa). The bigger documented hazard is the plant itself. CDC investigated an August 1983 California incident in which eight people were flown to hospital by helicopter after drinking juice pressed from elderberries crushed together with their leaves and branches. CDC concluded that leaves and stems should not be crushed in when making juice. Oregon State Extension states that all varieties of raw elderberries should be cooked before consuming. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

Chicken of the woods

LaetiporusFungusIn season now

Aug 1 to Oct 31, peaking around Sep 15

Built from 3,647 research grade records in Ohio, counted as recorded, because a fungus is only photographed when it is fruiting.

The documented hazard here is the species itself rather than a lookalike. Florida IFAS Extension states that raw or undercooked Laetiporus has been reported to cause gastrointestinal problems and that at least some individuals are allergic to it. Missouri notes swollen lips and stomach upset in some people even after cooking. Have it identified by a person.

Pawpaw

Asimina trilobaPlant, fruitautumn

Jul 1 to Sep 30, peaking around Sep 15

Built from 814 research grade records in Ohio, restricted to records annotated as fruiting, so the dates track fruit rather than flower.

NC State Extension rates pawpaw severity low, names acetogenins as the toxic principle, and records that contact dermatitis is known to occur, recommending gloves when harvesting. It notes stomach and intestinal pain from eating the fruit skin or seeds. Claims that eating pawpaw causes human neurodegeneration are not established; the neurotoxicity work concerns a different genus and cell cultures, not people. Have it identified by a person. Telling them apart is a job for a person with the specimen, and this page is not enough to eat anything.

American persimmon

3,647 research grade iNaturalist records of Laetiporus in Ohio, grouped by the month they were observed.Counted as recorded: a fungus is only photographed when it is fruiting, so the raw curve is already a fruiting curve. The adjusted series divides by all observations in the state that month, which removes observer effort.Adjusted view: each month’s records divided by all research-grade observations recorded in the same place that month, rescaled so the busiest month is 100. It answers “what share of what people found was this animal”, which is closer to activity than a raw tally.

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 Ohio records on iNaturalist.

Before you eat anything you found in Ohio

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.
