Description:
Chlorophyllum molybdites, which has the common names of false parasol, green-spored Lepiota and vomiter, is a widespread mushroom. Highly poisonous and producing severe gastrointestinal symptoms of vomiting and diarrhea, it is commonly confused with the shaggy parasol or shaggy mane, and is the most commonly consumed poisonous mushroom in North America. Its large size and similarity to the edible parasol mushroom, 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) up to 40 cm 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. The tall stipe may be up to 25 cm tall and bears a ring. This mushroom lacks the snakeskin pattern that is generally present on the parasol mushroom.
Distribution and habitat:
Chlorophyllum molybdites grows in lawns and parks across eastern North America and California, as well as temperate and subtropical regions around the world. Fruiting bodies generally appear after summer and autumn rains. It appears to have spread to other countries, with reports from Scotland, Australia, and Cyprus.
Toxicity:
Chlorophyllum molybdites is the poisonous mushroom most frequently eaten in North America. The symptoms are predominantly gastrointestinal in nature, with vomiting, diarrhea and colic, often severe, occurring 1–3 hours after consumption. Although these poisonings can be severe, none has yet resulted in death.
That said in “Common Florida Mushrooms” by James Kimbrough, the professor writes on page 325 of his book:
“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.“
