Chlorophyllum molybdites
Chlorophyllum molybdites, commonly known as the false parasol, is a species of fungus in the family Agaricaceae. It is widely distributed in tropical and subtropical regions around the world, and is often found in lawns, gardens, and other grassy areas. This mushroom is notorious for causing severe gastrointestinal distress if consumed.
Description[edit | edit source]
Chlorophyllum molybdites produces large, conspicuous fruiting bodies. The cap is initially hemispherical, becoming broadly convex to flat with age, and can reach up to 30 cm in diameter. The cap surface is white to tan, often with brownish scales. The gills are free from the stipe and are initially white, turning greenish as the spores mature. The stipe is sturdy, with a bulbous base, and can be up to 25 cm tall and 2.5 cm thick. A prominent, double-edged annulus is present on the stipe.
Spore Print[edit | edit source]
The spore print of Chlorophyllum molybdites is green, which is a key characteristic for identification. The spores are smooth, ellipsoid, and measure 10–14 by 6–9 µm.
Toxicity[edit | edit source]
Chlorophyllum molybdites is highly toxic and is responsible for the majority of mushroom poisonings in the United States. Ingestion leads to severe gastroenteritis, with symptoms including nausea, vomiting, diarrhea, and abdominal pain. Symptoms typically appear within 1 to 3 hours after consumption and can last for several days. There is no specific antidote, and treatment is supportive, focusing on rehydration and symptom management.
Habitat and Distribution[edit | edit source]
Chlorophyllum molybdites is commonly found in lawns, pastures, and other grassy areas, often in large fairy rings. It is widely distributed in tropical and subtropical regions, including parts of North America, South America, Africa, Asia, and Australia.
Similar Species[edit | edit source]
Chlorophyllum molybdites can be confused with edible species such as Macrolepiota procera (the parasol mushroom) and Lepiota species. However, the green spore print of C. molybdites is a distinguishing feature.
