Amanita subpallidorosea is a mushroom of the large genus Amanita , which occurs under oaks in southern China and Taiwan.
Amanita subpallidorosea is a medium-sized mushroom, and predominantly white. The cap is initially conical, before becoming more convex and flattening , sometimes with a central boss. Measuring 3 to 6.5 centimetres (1+1⁄4 to 2+1⁄2 inches) in diameter, the cap is white initially, before developing a pale pink, more prominently in the centre and paler at the margins. It can be slightly sticky when wet. The flesh is white. The crowded gills are free and around 4 millimetres (1⁄8 in) deep. The stipe is 7 to 12 cm (2+3⁄4 to 4+3⁄4 in) high and 0.6 to 1.4 cm (1⁄4 to 1⁄2 in) thick, is white, cream or pale buff in colour and bears a thin white membranous ring. The bulb at the base is 1.5 to 3 cm (1⁄2 to 1+1⁄4 in) across. The spore print is white, and the round amyloid spores are 8–12 x 8–12 μm viewed under a microscope. Their surface is smooth. The mushroom turns yellow when potassium hydroxide is applied to it. [1]
It can be distinguished from Amanita pallidorosea as the latter's cap has a pronounced boss and its spores are smaller when viewed under a microscope. Other lethal amanitas in China are generally white. [1]
It is closely related to the destroying angel mushrooms A. virosa and A. ocreata . [2]
A. subpallidorosea is found under oaks of the genera Quercus and Cyclobalanopsis in Guizhou province as well as Taiwan. [1]
Two people died in 2014 after eating mushrooms picked near Zunyi in Guizhou province in southwestern China; investigations led to the description of Amanita subpallidorosea in 2015. [2] Molecular analysis found it to be closely related to the destroying angel species A. virosa and A. ocreata. [1] The mushrooms all belong to a clade within the section Phalloideae, a large group of highly toxic mushrooms responsible for the deaths of many people worldwide. [2]
The name destroying angel applies to several similar, closely related species of deadly all-white mushrooms in the genus Amanita. They are Amanita virosa in Europe and A. bisporigera and A. ocreata in eastern and western North America, respectively. Another European species of Amanita referred to as the destroying angel, Amanita verna - also referred to as the 'Fool's mushroom' - was first described in France in 1780.
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 virosa, commonly known in Europe as the destroying angel or the European destroying angel amanita, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe, A. virosa associates with various deciduous and coniferous trees. The large fruiting bodies appear in summer and autumn; the caps, stipes and gills are all white in colour.
Amanita caesarea, commonly known as Caesar's mushroom, is a highly regarded edible mushroom in the genus Amanita, native to southern Europe and North Africa. While it was first described by Giovanni Antonio Scopoli in 1772, this mushroom was a known favorite of early rulers of the Roman Empire.
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 calyptroderma also known as coccora, coccoli or the Pacific amanita, is a white-spored mushroom that fruits naturally in the coastal forests of the western United States during the fall and winter and spring.
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.
Agaricus campestris is a widely eaten gilled mushroom closely related to the cultivated button mushroom Agaricus bisporus. It is commonly known as the field mushroom or, in North America, meadow mushroom.
Amanita velosa, commonly known as the springtime amanita, or bittersweet orange ringless amanita is a species of agaric found in California, as well as southern Oregon and Baja California. Although a prized edible mushroom, it bears similarities to some deadly poisonous species.
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. 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. A. ocreata resemble several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Mature fruiting bodies can be confused with the edible A. velosa, A. lanei or Volvopluteus gloiocephalus, while immature specimens may be difficult to distinguish from edible Agaricus mushrooms or puffballs.
Amanita arocheae, also known as the Latin American death cap, is a mushroom of the large genus Amanita, which occurs in Colombia, Central America and South America. Deadly poisonous, it is a member of section Phalloideae and related to the death cap, A. phalloides.
Amanita daucipes is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edibility is unknown for the species, but consumption is generally not recommended due its position in the Amanita subgroup Lepidella, which contains some poisonous members.
Amanita bisporigera is a deadly poisonous species of fungus in the family Amanitaceae. It is commonly known as the eastern destroying angel amanita, the eastern North American destroying angel or just as the destroying angel, although the fungus shares this latter name with three other lethal white Amanita species, A. ocreata, A. verna and A. virosa. The mushroom has a smooth white cap that can reach up to 10 centimetres across and a stipe up to 14 cm tall with a white skirt-like ring near the top. The bulbous stipe base is covered with a membranous sac-like volva. The white gills are free from attachment to the stalk and crowded closely together. As the species name suggests, A. bisporigera typically bears two spores on the basidia, although this characteristic is not immutable. A. bisporigera closely resembles a few other white amanitas, including the equally deadly A. virosa and A. verna.
Amanita aestivalis, commonly known as the white American star-footed amanita, is a species of fungus in the mushroom family Amanitaceae. The cap of the white fruit body is 5 to 8.5 centimetres in diameter. It sits atop a stem that is 8.5 to 16 cm long. The entire fruit body will slowly stain a reddish-brown color in response to bruising. A. aestivalis may be a synonym for A. brunnescens, and may be confused with several other white-bodied amanitas. The fungus is distributed in eastern North America.
Amanita exitialis, also known as the Guangzhou destroying angel, is a deadly poisonous mushroom of the large genus Amanita. The fruit bodies (mushrooms) are white, small to medium-sized with caps up to 7 centimetres in diameter. It is a member of section Phalloideae and related to A. phalloides.
Amanita australis is a species of fungus in the family Amanitaceae. It produces small- to medium-sized fruit bodies, with brown caps up to 9 centimetres in diameter covered with pyramidal warts. The gills on the underside of the cap are white, closely crowded together, and free from attachment to the stem. The stem, up to 9 cm long, has a ring and a bulbous base. The mushroom may be confused with another endemic New Zealand species, A. nothofagi, but can be distinguished by differences in microscopic characteristics.
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 zambiana, commonly known as the Zambian slender Caesar, is a basidiomycete fungus in the genus Amanita. An edible mushroom, it is found in Africa, where it is commonly sold in markets.
Amanita basii is a mushroom of the family Amanitaceae.
Amanita spreta or the hated amanita is an inedible species of the genus Amanita.
