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. [1]

This medium to large agaric has a cap with a diameter measuring 5–14 centimetres (2–5+12 inches) and a stipe length of up to 15 cm (6 in) and a thickness of 0.5–3 cm (141+14 in). Gills on the cap underside are free from attachment to the stipe, crowded closely together, and white to cream in colour with brownish edges. The fruit body has a sac-like volva and lacks a ring on the stipe. The overall colour of the fruit body is brownish with a yellowish to orange cap centre. Its spores are spherical or nearly so, measuring 10–14 by 9.5–13  µm. Names for its similarity to the widespread A. fulva (a species with which it was previously confused), it can be distinguished by microscopic features of the volva. [1]

It is found at altitudes ranging from 1,300–4,200 m (4,300–13,800 ft) in south-western China. It is associated with trees, especially Abies , Quercus , Salix , and occasionally Castanopsis . [1]

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.

<i>Amanita velosa</i> Species of fungus

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.

<i>Amanita ocreata</i> Species of poisonous fungus in the genus Amanita

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.

<i>Amanita brunnescens</i> Species of fungus

Amanita brunnescens, also known as the brown American star-footed amanita or cleft-footed amanita is a native North American mushroom of the large genus Amanita. It differs from A. phalloides by its fragile volva and tendency to bruise brown.

<i>Amanita arocheae</i> Species of fungus

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.

<i>Amanita bisporigera</i> Poisonous species of fungus in the family Amanitaceae endemic to North America

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.

<i>Amanita aestivalis</i> Species of fungus

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.

<i>Amanita exitialis</i> Species of fungus

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.

<i>Amanita australis</i> Species of fungus

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.

<i>Amanita nothofagi</i> Species of fungus

Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.

Amanita ceciliae, commonly called snakeskin grisette, strangulated amanita, and the Cecilia's ringless amanita, is a basidiomycete fungus in the genus Amanita. First described in 1854 by Miles Joseph Berkeley and Christopher Edmund Broome, it was given its current name by Cornelis Bas in 1984. It is characterized by bearing a large fruit body with a brown cap 5–12 cm (2.0–4.7 in) across. The cap has charcoal-grey patches, which are easily removable. The stipe is 7–18 cm (2.8–7.1 in) long, white in colour, and there is no ring on it. It is slightly tapered to the top, and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. A. ceciliae is found in woods throughout Europe and North America, where it fruits during summer and autumn.
