Orange Mushroom in Yard: Red and Orange Lawn Fungi

Orange and red mushrooms in a yard sort into three groups by substrate, and substrate is far more reliable than shade of orange.

• On wood — a stump, a buried root, a wood-chip bed. Tight clusters of bright orange caps here are most likely Omphalotus illudens, the eastern jack-o'-lantern, which grows in clusters from wood or buried wood. Rusty orange clusters with rusty spore prints are more likely Gymnopilus species.
• From soil near a tree. A red or orange cap with white warts, white gills and a bulbous base is Amanita muscaria, the fly agaric, which forms partnerships with birch, pine and spruce and fruits on lawns near those host trees as well as in woodland.
• Directly in old, undisturbed turf. Small, brightly coloured caps with a waxy or greasy feel are waxcaps, genus Hygrocybe. They are grassland specialists and a sign of turf that has not been heavily fertilised.

If you cannot tell whether the stem comes from soil or from wood, dig. Buried construction lumber and dead roots are, as UC IPM notes, the usual food source under lawns, and a mushroom can look soil-borne while its base sits on a board four inches down.

Omphalotus illudens is the orange mushroom most worth recognising in an American yard, because it is one of the best documented mistakes in North American foraging.

Identification points:

• Colour. Bright orange to yellowish orange throughout, cap, gills and stem.
• Gills. True gills, sharp-edged, running down the stem. This is the point that separates it from chanterelles, which have blunt forking ridges rather than true gills.
• Habit. Dense clusters fused at the base, arising from wood or buried wood. Chanterelles grow singly or scattered from soil.
• Glow. Fresh gills show a weak green bioluminescence, reported to persist 40 to 50 hours after picking. Take the mushroom into a completely dark room and let your eyes adjust for several minutes.

On risk: its documented toxins are illudins, which cause severe cramps and diarrhoea; older sources also cite muscarine, but Wikipedia notes modern studies have not confirmed it is present. It is described as not deadly, but consuming it may require hospital treatment. That is a meaningful distinction from the amatoxin group and no reason to relax around it, especially where dogs dig at old stumps.

In a yard, a jack-o'-lantern cluster is a marker: there is wood down there. That is also your removal target if you want the mushrooms gone for good.

A red or orange-red cap dotted with white warts, on a white stem with a skirt-like ring and a bulbous base, is the fly agaric, Amanita muscaria.

The warts are remnants of the universal veil that enclosed the young mushroom; young buttons can be almost entirely covered in them, and heavy rain washes them off, so an older cap can be plain red. The base is the constant feature: bulbous, with shaggy rings of scales, where the rest of the veil stayed behind.

It is mycorrhizal with birch, pine and spruce, which is why it turns up on lawns and in landscaped ground near planted trees rather than only in forest. It contains ibotenic acid, which converts to muscimol, and is poisonous as well as psychoactive.

For a yard, three practical points:

• The colour makes it attractive to small children. Remove it on sight where toddlers play.
• It is the same genus as the death cap and the destroying angels, so the habit of digging the base out and looking at it applies here too.
• Its presence says a host tree is nearby, so expect it in the same place each autumn.

More on Amanita muscaria.

Small, vividly coloured caps sitting low in old turf are usually waxcaps, genus Hygrocybe. The group name comes from the moist, waxy or greasy texture of the cap and the thick waxy gills, and all of them produce white spore prints.

Several small red and orange species occur in grassland, including the vermilion waxcap Hygrocybe miniata, a small bright red to red-orange mushroom of fields, sandy heaths and grassy clearings in autumn. Reference guides are frank that separating the various small red, orange and yellow waxcaps is notoriously difficult and many cannot be identified with certainty without microscopic analysis.

Waxcaps matter for a different reason than toxicity. They are associated with old, unimproved grassland that has not been heavily fertilised or disturbed, so a lawn that produces a good range of waxcaps is an ecologically interesting one. If you like them, they are an argument for feeding that area less rather than more.

• Photograph before removing. Cap from above, gills from below, the whole stem with base, and note whether it rose from soil or wood. Photograph it with the app and it identifies it.
• Do the dark-room check if you suspect a jack-o'-lantern cluster and want to confirm; fresh gills glow faintly green.
• Remove where children and dogs play. Bright orange and red are the colours toddlers reach for.
• Find the wood. Orange clusters in turf almost always sit over buried wood. Digging it out is the permanent fix described on how to get rid of mushrooms in a lawn.
• No edibility calls. Poison Control's guidance is that only experts in mushroom identification can separate poisonous species from harmless ones. This site never tells you a wild mushroom is safe to eat.
• If someone has eaten one, call 1-800-222-1222 right away without waiting for symptoms, and keep a specimen in a paper bag. For a dog or cat, call your vet or ASPCA Animal Poison Control at (888) 426-4435.

A reddish-orange mushroom coming up in wood chips or a garden bed is very often Leratiomyces ceres, sometimes called the redlead roundhead or chip cherry. Wikipedia calls it one of the most common and distinctive mushrooms of wood-chip mulch and describes a bright red to orange cap 2 to 6 cm across, gills that start white to pale grey and turn purple-brown with whitish edges, and a dark purple-brown spore print. It is common in parts of North America, Europe, Australia and New Zealand. Its toxicity is unknown, which is a reason to keep children and pets away from it, not a reason to think it harmless.

It is also the answer given in one of the top-ranking forum threads for this search: a moderator on the Wild Mushroom Hunting forum identified red-orange mushrooms in a San Francisco garden box as Leratiomyces ceres. The purple-brown spore print separates it quickly from the white-spored jack-o'-lantern.

No source we checked describes it as psychoactive. Wikipedia describes the orange mycena, Mycena leaiana, as an inedible North American species that grows in dense clusters on hardwood logs and branches, with bright orange caps 1 to 4 cm across that fade with age, yellowish gills with bright orange-red edges, and an orange-yellow pigment that rubs off and stains the skin. It records a compound called leaianafulvene with cytotoxic and mutagenic properties in laboratory tests. None of that makes it a mushroom to eat or experiment with.

The orange mushrooms that do come up in psychoactive discussions are mostly Gymnopilus species. Wikipedia notes that the spectacular rustgill, Gymnopilus junonius, lacks psilocybin, contains neurotoxins such as gymnopilin, is bitter and inedible, and that North American look-alikes are often misidentified as it.

Besides the jack-o'-lantern, the other large orange cluster on stumps is Gymnopilus. Wikipedia describes Gymnopilus junonius with caps 5 to 30 cm across, bright yellow-orange when young and orange-brown to reddish brown later, a dry scaly surface, a rusty-brown spore print, and clusters of several to several dozen on hardwood and conifer stumps and logs. Wikipedia also states this species does not occur in North America, where similar Gymnopilus species are often misidentified as it. The rusty-brown spore print separates the group from the jack-o'-lantern, which prints white to cream.

Bright orange cups on a path or bare, disturbed soil are usually the orange peel fungus, Aleuria aurantia. Wikipedia describes cup-shaped fruit bodies 1 to 10 cm wide, fuzzy underneath and fragile, fruiting from November to March in the western US and May to November in the east. It warns that in Europe it can be confused with Otidea or Caloscypha species that are poisonous or of unknown edibility. It has no gills and no stem, so it is not confused with the orange gilled mushrooms above.

The red cage stinkhorn, Clathrus ruber, looks like a red to pale orange hollow lattice ball 5 to 20 cm tall rising from a whitish egg up to 6 cm across, and smells of rotting meat. Wikipedia notes that its edibility has not been officially documented, that an 1854 report describes a poisoning with painful tension, convulsions and loss of speech, and that British publications generally list it as inedible or poisonous. It grows in mulch beds, lawns, gardens and cultivated soil. Treat it like any other yard fungus: bag it, and call Poison Control if a child eats some. Other stinkhorns are covered on stinkhorn mushroom in yard.

This site does not say any orange mushroom is edible. Some orange species are gathered by foragers, such as chanterelles and chicken of the woods (A-Z Animals), but the most common orange mushroom in North American yards, the jack-o'-lantern, is poisonous and is mistaken for chanterelles every year, and others here are of unknown toxicity or inedible. Poison Control's position is that unless you are very experienced in mushroom identification, you cannot tell edible from poisonous. If anyone has eaten an orange mushroom, call 1-800-222-1222.
