Conocybe tenera is a small saprotrophic mushroom with a conic to convex cap and is smooth and colored cinnamon brown. It is usually less than 2 cm across and is striate almost to the center. It is usually less than 2 cm across and is striate almost to the center.
Mycena is a rich genus, considered one of the most abundant genera of mushrooms within the Agaricales and with species distributed across the world. [ 5 ] Alexander Smith's 1947 Mycena monograph identified 232 species; the genus is now known to include about 500 species worldwide. [ 12 ]
The genus Amanita was first published with its current meaning by Christian Hendrik Persoon in 1797. [1] Under the International Code of Botanical Nomenclature, Persoon's concept of Amanita, with Amanita muscaria (L.) Pers. as the type species, has been officially conserved against the older Amanita Boehm (1760), which is considered a synonym of Agaricus L. [2]
As with other wild-growing mushrooms, the ratio of ibotenic acid to muscimol depends on countless external factors, including: season, age, and habitat—and percentages will naturally vary from mushroom to mushroom—with dark brown A. pantherina specimens having a greater concentration of ibotenic acid.
The mushroom's odour is strong and sweet, similar to almond extract, marzipan or maraschino cherry, due to the presence of benzaldehyde and benzyl alcohol. [6] [7] Its taste has been described as not distinctive. Under a microscope, the ellipsoid-shaped spores are seen characteristically large at 7–10 by 4.5–6.5 μm. The basidia are 4-spored.
Conocybe is a genus of mushrooms with Conocybe tenera as the type species and at least 243 other species. There are at least 50 different species in North America. Most have a long, thin fragile stipe and are delicate, growing in grasslands on dead moss, dead grass, sand dunes, decayed wood, and dung.
Examples exist in the mushroom genera Armillaria and Xerula, both in the Physalacriaceae. Occasionally, basidiospores are not formed and parts of the "basidia" act as the dispersal agents, e.g. the peculiar mycoparasitic jelly fungus, Tetragoniomyces or the entire "basidium" acts as a "spore", e.g. in some false puffballs ( Scleroderma ).
Symptoms of death cap mushroom toxicity usually occur 6 to 12 hours after ingestion. [77] Symptoms of ingestion of the death cap mushroom may include nausea and vomiting, which is then followed by jaundice, seizures, and coma which will lead to death. The mortality rate of ingestion of the death cap mushroom is believed to be around 10–30%. [78]
