Amanita phalloides, commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, but introduced to other parts of the world since the late twentieth century, A. phalloides forms ectomycorrhizas with various broadleaved trees. In some cases, the death cap has been introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies (mushrooms) appear in summer and autumn; the caps are generally greenish in colour with a white stipe and gills. The cap colour is variable, including white forms, and is thus not a reliable identifier.
The genus Amanita contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. The genus is responsible for approximately 95% of fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-Amanitin.
Amanita gemmata, commonly known as the gemmed amanita or the jonquil amanita, is an agaric mushroom of the family Amanitaceae and genus Amanita. The fruit body has a cap that is a dull to golden shade of yellow, and typically 2.5–12 centimetres in diameter. The cap surface is sticky when moist, and characterized by white warts, which are easily detached. It is initially convex, and flattens out when mature. The flesh is white and does not change colour when cut. The gills are white and closely spaced. The stem is pale yellow, and measures 4–12 cm long by 0.5–1.9 cm thick. The partial veil that covers the young fruit body turns into the ring on the stem at maturity. The spore print is white. It resembles numerous other species.
Amanita altipes, also called the yellow long-stem amanita, is a species of agaric fungus found in coniferous woodlands in southwestern China.
Amanita liquii, also known as the dark-faced ringless amanita, is a species of agaric that fruits from July to September.
Amanita orientifulva, also known as the Asian orange-brown ringless amanita, is a species of agaric fungus that fruits singly or scattered from June to September.
Amanita subjunquillea, also known as the East Asian death cap is a mushroom of the large genus Amanita, which occurs in East and Southeast Asia. Potentially deadly if ingested, it is closely related to the death cap A. phalloides.
Amanita vaginata, commonly known as the grisette or the grisette amanita, is an edible mushroom in the fungus family Amanitaceae. The cap is gray or brownish, 5 to 10 centimetres in diameter, and has furrows around the edge that duplicate the gill pattern underneath. Unlike many other Amanita mushrooms, A. vaginata lacks a ring on the stem.
Amanita exitialis, also known as the Guangzhou destroying angel, is a mushroom of the large genus Amanita. It is distributed in eastern Asia, and probably also in India where it has been misidentified as A. verna. Deadly poisonous, it is a member of section Phalloideae and related to the death cap A. phalloides. The fruit bodies (mushrooms) are white, small to medium-sized with caps up to 7 cm (2.8 in) in diameter, a somewhat friable ring and a firm volva. Unlike most agaric mushrooms which typically have four-spored basidia, the basidia of A. exitialis are almost entirely two-spored. Eight people were fatally poisoned in China after consuming the mushroom in 2000, and another 20 have been fatally poisoned since that incident. Molecular analysis shows that the species has a close phylogenetic relationship with three other toxic white Amanitas: A. subjunquillea var. alba, A. virosa and A. bisporigera.
Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 millimetres wide. The stems are up to 10 cm (4 in) tall, cream-coloured above the ring and cream to yellowish below it. The stem ends in a roughly spherical bulb at the base, which is covered with bright orange patches.
Amanita fuliginea, commonly known as the east Asian brown death cap, is a species of deadly poisonous mushroom in the family Amanitaceae. The fruit bodies have convex, dark gray to blackish caps measuring 3–6 cm (1.2–2.4 in) in diameter. The gills, largely free from attachment to the stipe, are white and have short gills (lamellulae) interspersed. The spores are roughly spherical, amyloid, and typically measure 8–11 by 7–9.5 µm. The species was described as new to science by Japanese mycologist Tsuguo Hongo in 1953. A. fuliginea is classified in Amanita section Phalloideae, which contains the infamous destroying angel.
Amanita sinicoflava, the mandarin yellow ringless amanita, is an edible species of fungus in the large genus Amanita.
Amanita chepangiana, commonly known as the Chepang slender Caesar, is a species of agaric fungus in the family Amanitaceae native to China and southern Asia.
Amanita manginiana, also known as Mangin's false death cap, Chiu's false death cap, is a species of the genus Amanita.
Amanita subpallidorosea is a mushroom of the large genus Amanita, which occurs under oaks in southern China and Taiwan.
Amanita subfuliginea is a mushroom of the large genus Amanita, which occurs central and southern China. It is closely related to the east Asian death cap A. fuliginea.
Amanita griseorosea is a mushroom of the large genus Amanita, which occurs under beech in southern China. It is closely related to A. molliuscula.
Amanita princeps, the head man slender Caesar, is a species of agaric fungus in the genus Amanita. It is found in tropical China, Southeast Asia, and the Malay Peninsula down to Singapore. It is edible, and is collected in the wild and sold in local markets. Many incidents of mushroom poisoning have occurred among Laotian and Hmong immigrants to North America, since it is easily confused with Amanita phalloides, the death cap, in both appearance and odor.
Amanita sculpta is a species of Amanita. It is distinctive because of its large size, with caps 10 to 27 centimetres in diameter. The cap's appearance, beige and dark brown with pileal warts, has been compared to that of a chocolate chip cookie.
