Chlorophyllum molybdites, commonly known as the green-spored parasol, [1] false parasol, green-spored lepiota and vomiter, is a widespread mushroom. Poisonous and producing severe gastrointestinal symptoms of vomiting and diarrhea, it is commonly confused with the shaggy parasol (Chlorophyllum rhacodes) or shaggy mane (Coprinus comatus), and is the most commonly misidentified poisonous mushroom in North America. [2] Its large size and similarity to the edible parasol mushroom (Macrolepiota procera), as well as its habit of growing in areas near human habitation, are reasons cited for this. The nature of the poisoning is predominantly gastrointestinal.
It is an imposing mushroom with a pileus (cap) ranging from 8 to 30 cm (3.1 to 12 in) in diameter, hemispherical and with a flattened top. The cap is whitish in colour with coarse brownish scales. The gills are free and white, usually turning dark and green with maturity. It has a rare green spore print. [3] The stipe ranges from 5 to 30 cm (2.0 to 12 in) tall and bears a double-edged ring. [3] Its stem lacks the snakeskin pattern that is generally present on the parasol mushroom. [4] Flesh thick, firm at first, soft with age, white, unchanging or sporadically becoming reddish-brown to pale reddish-pink, almost orange in the base of the foot when cut or crushed.
Chlorophyllum molybdites grows in lawns and parks across eastern North America and California, as well as temperate and subtropical regions around the world. [5] Fruiting bodies generally appear after summer and autumn rains. It appears to have spread to other countries, with reports from Scotland, Australia, and Cyprus. [6]
Chlorophyllum molybdites is the most frequently eaten poisonous mushroom in North America. [2] The symptoms are predominantly gastrointestinal in nature, with vomiting, diarrhea and colic, often severe, occurring 1–3 hours after consumption. [5] Although these poisonings can be severe, particularly in children, [3] none has yet resulted in death. [7]
Professor James Kimbrough writes:
Chlorophyllum molybdites, the green-spored Morgan's Lepiota, is responsible for the greatest number of cases of mushroom poisonings in North America, and in Florida. This is probably due to the fact that it is easily confused with choice edible species such as Lepiota procera and L. rhacodes, and it is one of the most common mushrooms found on lawns and pastures throughout the country, with the exception of the Pacific Northwest. When eaten raw C. molybdites produce severe symptoms, including bloody stools, within a couple of hours. When cooked well, or parboiled and decanting the liquid before cooking, others eat and enjoy it. Eilers and Nelso (1974) found a heat-labile, high molecular weight protein which showed an adverse effect when given by intraperitoneal injection into laboratory animals. [8]
Cases of poisoning from these mushrooms are also reported in Malaysia, where they are often mistaken for Termitomyces mushrooms that are found locally. [9]
Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild. This is typically done for culinary use, although medicinal and psychotropic uses are also known. This practice is popular throughout most of Europe, Australia, Japan, Korea, parts of the Middle East, and the Indian subcontinent, as well as in the temperate regions of Canada and the United States.
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus.
Lepiota is a genus of gilled mushrooms in the family Agaricaceae. All Lepiota species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of Lepiota are currently recognized worldwide. Many species are poisonous, some lethally so.
Shaggy parasol is the common name for three closely related species of mushroom, Chlorophyllum rhacodes, C. olivieri and C. brunneum, found in North America, Europe and Southern Africa.
Hypholoma fasciculare, commonly known as the sulphur tuft or clustered woodlover, is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.
Coprinus comatus, commonly known as the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The caps are white, and covered with scales—this is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and deliquesce ('melt') into a black liquid filled with spores. This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.
Macrolepiota procera, the parasol mushroom, is a basidiomycete fungus with a large, prominent fruiting body resembling a parasol. It is a fairly common species on well-drained soils. It is found solitary or in groups and fairy rings in pastures and occasionally in woodland. Globally, it is widespread in temperate regions.
Rubroboletus satanas, commonly known as Satan's bolete or the Devil's bolete, is a basidiomycete fungus of the bolete family (Boletaceae) and one of its most infamous members. It was known as Boletus satanas before its transfer to the new genus Rubroboletus in 2014, based on molecular phylogenetic data. Found in broad-leaved and mixed woodland in the warmer regions of Europe, it is classified as a poisonous mushroom, known to cause gastrointestinal symptoms of diarrhea and violent vomiting. However, reports of poisoning are rare, due to its striking appearance and at times putrid smell, which discourage casual experimentation.
Amanita verna, commonly known as the fool's mushroom or the spring destroying angel, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe in spring, A. verna associates with various deciduous and coniferous trees. The caps, stipes and gills are all white in colour.
Galerina marginata, known colloquially as funeral bell, deadly skullcap, autumn skullcap or deadly galerina, is a species of extremely poisonous mushroom-forming fungus in the family Hymenogastraceae of the order Agaricales. It contains the same deadly amatoxins found in the death cap. Ingestion in toxic amounts causes severe liver damage with vomiting, diarrhea, hypothermia, and eventual death if not treated rapidly. About ten poisonings have been attributed to the species now grouped as G. marginata over the last century.
Chlorophyllum is a genus of large agarics similar in appearance to the true parasol mushroom. Chlorophyllum was originally coined in 1898, a time when spore color was the deciding factor for differentiating genera. It was termed in order to describe the poisonous green-spored C. molybdites which shared many characteristics of the mushrooms within the genus Lepiota but lacked the all important white spores. The name derives from Greek Chloro meaning green and phyllo meaning leaf. It remained as a monotypic genus until recently when modern DNA analyses concluded that many of the mushrooms contained in the genus Macrolepiota actually had more in common genetically with the Chlorophyllum molybdites than with the other members of the Macrolepiota. The genus has a widespread distribution, with many species found in tropical regions. The best known members are the edible shaggy parasol, a name applied to three very similar species Chlorophyllum rhacodes, C. olivieri and C. brunneum, and the poisonous C. molybdites, which is widespread in subtropical regions around the world.
Amanita ocreata, commonly known as the death angel, destroying angel, angel of death or more precisely western North American destroying angel, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in the Pacific Northwest and California floristic provinces of North America, A. ocreata associates with oak trees. The large fruiting bodies generally appear in spring; the cap may be white or ochre and often develops a brownish centre, while the stipe, ring, gill and volva are all white.
Hebeloma crustuliniforme, commonly known as poison pie or fairy cakes, is a gilled mushroom of the genus Hebeloma found in Europe and North America, and has been introduced into Australia. Its specific name derives from the Latin crustulum or little biscuit. It is moderately poisonous.
Lepiota brunneoincarnata, the deadly dapperling, is a gilled mushroom of the genus Lepiota in the order Agaricales. Widely distributed in Europe and temperate regions of Asia as far east as China, it grows in grassy areas such as fields, parks and gardens, and is often mistaken for edible mushrooms. The mushroom has a brown scaled cap up to 4 cm wide with a pinkish brown stem and white gills. It is highly toxic, with several deaths having been recorded as it resembles the edible grey knight and fairy ring champignon.
Macrolepiota clelandii, commonly known as the slender parasol or graceful parasol, is a species of mushroom-forming fungus in the family Agaricaceae. The species is found in Australia and New Zealand, where it fruits singly or in small groups on the ground in eucalypt woodlands, parks, and roadsides. It is a tall mushroom up to roughly 20 cm (8 in), with a broad cap covered with distinctive rings of dark brown scales. The whitish gills on the cap underside are closely spaced and free from attachment to the slender stipe, which has a loose ring on its upper half, and a bulbous base. The edibility of the mushroom is not known with certainty, but closely related parasol mushrooms are edible and some are very sought after.
Lepiota castanea, commonly known as the chestnut dapperling or petite parasol, is a deadly poisonous, uncommon, gilled mushroom of the genus Lepiota in the order Agaricales. It is known to contain amatoxins and consuming this fungus can be a potentially lethal proposition. It was described by French mycologist Lucien Quélet in 1881.
Galerina sulciceps is a dangerously toxic species of fungus in the family Strophariaceae, of the order Agaricales. It is distributed in tropical Indonesia and India, but has reportedly been found fruiting in European greenhouses on occasion. More toxic than the deathcap, G. sulciceps has been shown to contain the toxins alpha- (α-), beta- (β-) and gamma- (γ-) amanitin; a series of poisonings in Indonesia in the 1930s resulted in 14 deaths from the consumption of this species. It has a typical "little brown mushroom" appearance, with few obvious external characteristics to help distinguish it from many other similar nondescript brown species. The fruit bodies of the fungus are tawny to ochre, deepening to reddish-brown at the base of the stem. The gills are well-separated, and there is no ring present on the stem.
Leucoagaricus americanus, commonly known as the American parasol, is a mushroom in the genus Leucoagaricus, native to North America. It was first described by Charles Horton Peck, an American mycologist of the 19th and early 20th centuries, in 1869. It is widely distributed in North America, though more common east of the Rocky Mountains; it is saprobic, and grows on sawdust, on wood chips, on stumps, and on the ground.
Lepiota cristata, commonly known as the stinking dapperling, brown-eyed parasol, or the stinking parasol, is an agaric and possibly poisonous mushroom in the family Agaricaceae. A common and widespread species—one of the most widespread fungi in the genus Lepiota—it has been reported from Europe, northern Asia, North America, and New Zealand. It fruits on the ground in disturbed areas, such as lawns, path and road edges, parks, and gardens. The species produces fruit bodies characterized by the flat, reddish-brown concentric scales on the caps, and an unpleasant odour resembling burnt rubber. Similar Lepiota species can sometimes be distinguished from L. cristata by differences in cap colour, stipe structure, or odour, although some species can only be reliably distinguished through the use of microscopy.
Chlorophyllum agaricoides, known commonly as the puffball parasol, false puffball, or puffball agaric, is a species of fungus belonging to the family Agaricaceae. When young, it is edible, and has been traditionally eaten in Turkey for many years.
