Mycoscout How to identify meadow mushrooms
The meadow mushroom (Agaricus campestris) is a white-capped, short-stemmed mushroom of pastures, lawns and playing fields, often in arcs or fairy rings. Its gills are its signature: deep pink as soon as the cap opens, then brown, then almost black, with a dark chocolate-brown spore print. The two deadly white Amanitas that share this habitat have white gills and a white spore print, and the poisonous yellow stainer turns chrome yellow where it is cut.
| Feature | Meadow mushroom (field mushroom) |
|---|---|
| Cap | 3–10 cm (First Nature); 1–4 in (Missouri Department of Conservation). Creamy white to grayish, dry, smooth or with small brownish scales. The margin stays turned down even when the cap is fully open. |
| Gills | Free of the stem, crowded. Deep pink from the start, darkening to chocolate brown and finally blackish. Never white. |
| Stem & base | 3–10 cm tall, 1–2 cm thick, white, roughly parallel-sided or tapering slightly downward. No cup or sac at the base. A single, thin ring that collapses early and is often gone at maturity. |
| Flesh | Thick and white. May turn faintly pink when cut. Never yellow. |
| Spore print | Dark chocolate brown to blackish brown. |
| Smell | Not distinctive; like a shop-bought button mushroom. |
| Habitat | Grass: pasture, meadows, lawns, parks, playing fields. Singly, in groups, in arcs or fairy rings. Not on wood. |
| Season | June–October in Britain and Ireland (First Nature); July–September in Missouri (MDC). |
| Range (US / UK & Europe) | US: "meadow mushroom" covers a group of near-identical species; MushroomExpert says the true A. campestris is not known east of the Rockies, while MDC lists the meadow mushroom statewide in Missouri. UK & Europe: common and widespread. |
Confirm these features
- Gills pink, pinkish brown or chocolate brown. Any white in the gills of an open cap rules this mushroom out.
- Spore print dark chocolate brown to blackish. A white print means Amanita; stop.
- Dig up the whole stem base: there is no sac, cup or bulb. The base is plain white and roughly the same width as the stem.
- Cut the stem base and wait: the flesh stays white or goes faintly pink. Chrome yellow means yellow stainer.
- Smell the cut base: like a shop mushroom, not like ink, phenol or iodine.
- Growing in grass, not from wood, and not under trees where Amanitas fruit.
Why one feature is never enough: a closed button shows no gills, a shallow pick leaves the Amanita sac in the ground, and a yellow stain can take a moment to show. Missouri's field guide tells collectors to "make spore prints or show your specimens to an expert" before eating any Agaricus. Do all of the checks, every time.
Dangerous look-alikes
Destroying angel (Amanita bisporigera in the US, Amanita virosa in Europe)
Tell apart: pure white all over, including the gills and the spore print. A large skirt-like ring on the upper stem and a sac-like cup around the base, which can be hidden below the soil. MDC describes it in "mixed woods and in grass near trees", June–November. The meadow mushroom has pink-to-brown gills, a dark print, a thin fading ring and no cup. Risk: deadly. Amatoxins cause no symptoms for 6–24 hours, then vomiting, diarrhea and cramps, then an apparent recovery before liver and kidney failure (NAMA). See meadow mushroom vs destroying angel and the destroying angel page.
Death cap (Amanita phalloides)
Tell apart: the cap is usually olive-yellow to greenish bronze, not white, but pale forms exist. Gills are white, sometimes cream or faintly pink with age (Woodland Trust), with a floppy ring and a bag-like volva at the base. It grows under trees, particularly oak and beech, July–November, so a "meadow" mushroom found at the edge of a lawn under trees needs extra care. Risk: deadly, the same amatoxin syndrome as the destroying angel. See the death cap page.
Yellow stainer (Agaricus xanthodermus)
Tell apart: the same shape and the same pink-to-brown gills, but the cap and stem bruise chrome yellow, the cut stem base turns yellow at once, and it smells of ink, phenol or iodine. It favors hedgerows, gardens and park edges. Risk: poisonous. Stomach cramps, nausea, vomiting, sweating and diarrhea (First Nature). See field mushroom vs yellow stainer.
Horse mushroom (Agaricus arvensis)
Tell apart: larger (often 8–20 cm), the cap yellows slightly with age, with a double "cogwheel" ring and an aniseed smell. It is edible, but it is also confused with the yellow stainer, so apply the same stem-base test. Risk: low in itself; the danger is a yellow stainer mistaken for it.
Where and when it grows
The meadow mushroom is a grassland decomposer. It fruits in pasture, meadows, lawns, parks and playing fields, singly or in scattered groups, and quite often in fairy rings. First Nature gives June to October for Britain and Ireland; MDC gives July to September for Missouri, typically after rain. It does not grow on wood or stumps, which matters for ruling out other species, but it does grow in grass near trees, which is exactly where destroying angels appear.
In the US, the name "meadow mushroom" is applied to a group of look-alike Agaricus species that only differ in spore size. In Britain and Europe, A. campestris is common from lowland pasture to upland grazing. Both First Nature and MDC warn against collecting from roadsides, treated lawns or any site where lawn chemicals may have been used. If you are looking at mushrooms in your own lawn, our mushrooms in lawn guide covers the common ones.
Before you eat any
First Nature calls it a very good edible "provided they are properly cooked and eaten in moderation". MDC lists it as a choice edible with the note "extreme caution!", because the destroying angel shares its habitat, and advises cooking it thoroughly and eating a small amount the first time you try any new species. Confirm every specimen, not just the first one in a ring: buttons give you almost nothing to check. Take a spore print, dig the base, cut the stem, and show your finds to a local mycological society or an experienced forager before any go in the pan.
Using an app to check a find
A photo of a white cap in grass gives an app little to work with: the gill color, the spore print, the smell and the buried base are what separate this mushroom from a deadly one, and none of them shows from above. Mycoscout asks for the cap, gills, stem and habitat, leads with the edibility verdict, shows its confidence and names the destroying angel and yellow stainer as look-alikes with the feature to check. Treat the result as a starting point for the checklist above. No app, including Mycoscout, can clear a mushroom for eating.
Frequently asked questions
Can a meadow mushroom have white gills?
No. Every source we checked describes the gills as pink from the start, darkening to chocolate or blackish brown. A white-gilled mushroom in grass can be a destroying angel or a death cap, both deadly. Treat white gills as a stop sign, but check the base and take a spore print as well.
Meadow mushroom vs destroying angel: what is the difference?
The destroying angel has white gills, a white spore print, a skirt-like ring and a sac-like cup around the stem base that can sit below the soil. The meadow mushroom has pink-to-brown gills, a dark brown spore print, a thin ring that often disappears, and no cup. Dig up the whole base before deciding.
Field mushroom vs yellow stainer: how do you tell them apart?
Cut the stem base. The yellow stainer turns chrome yellow at once and smells of ink or phenol. The field mushroom never turns yellow and smells like a shop mushroom. The yellow stainer causes stomach cramps, vomiting and diarrhea.
Is the meadow mushroom the same as the field mushroom?
Yes. Agaricus campestris is called the meadow mushroom in the US and the field mushroom in the UK. In North America several near-identical species share the name, and MushroomExpert notes they can only be told apart under a microscope.
Are lawn mushrooms dangerous to dogs?
The Missouri Department of Conservation says the destroying angel, which grows in the same grass, affects pets and livestock as well as people. If a dog has eaten an unknown lawn mushroom, call a vet or an animal poison line now and do not wait for symptoms.
