Amanita muscaria, commonly known as the fly agaric or fly amanita, is a basidiomycete of the genus Amanita. It is a large white-gilled, white-spotted, and usually red mushroom.
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 pantherina, also known as the panther cap, false blusher, and the panther amanita due to its similarity to the true blusher, is a species of fungus found in Eurasia with poisonous and psychoactive properties.
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 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 chrysoblema yellow-orange variant, commonly known as the American yellow fly agaric, is a basidiomycete fungus of the genus Amanita. It is one of several varieties of muscaroid fungi, all commonly known as fly agarics or fly amanitas.
Amanita flavoconia, commonly known as yellow patches, yellow wart, orange amanita, yellow-dust amanita or the American yellow dust amanita, is a species of mushroom in the family Amanitaceae. It has an orangish-yellow cap with yellowish-orange patches or warts, a yellowish-orange annulus, and a white to orange stem. Common and widespread throughout eastern North America, A. flavoconia grows on the ground in broad-leaved and mixed forests, especially in mycorrhizal association with hemlock.
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 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 regalis, commonly known as the royal fly agaric or the king of Sweden Amanita, is a species of fungus in the family Amanitaceae. A. regalis has a scabby liver-brown cap and a stem which is yellow-ochre at the base, with patches or rings of patches. The fruit bodies somewhat resemble the smaller A. muscaria, which it was formerly regarded as a variety of.
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 nehuta, also called Maori dust amanita, is a species of fungus in the family Amanitaceae.It has only a dark ring rather than a universal veil and white spores. Abundant in New Zealand, it can be found growing under Leptospermum and Nothofagus species.
Amanita jacksonii, also known as Jackson's slender amanita, American Slender Caesar, and Eastern Caesar's Amanita, is a North American species of fungus in the family Amanitaceae. It is a reddish-orange colored mushroom species which can be identified by its yellow gills, large, white, sacklike volva.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.
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 albocreata, also called the ringless panther or the ringless panther amanita, is a species of fungus in the family Amanitaceae. It was discovered in 1944, by William Murrill. It is commonly found in northeastern United States and southeastern Canada and elsewhere in North America. This species, that grows about 5 to 15 centimeters in length, is doubted to be fatally toxic. It normally grows between the rainy months of June and August.
Amanita frostiana, also known as Frost's amanita, is a small yellow-to-red fungus found in eastern North America.
Amanita flavella is a species of mycorrhizal fungus from family Amanitaceae. It has a convex lemon-yellow coloured cap up to 9 centimetres in diameter. They can also be yellowish-orange coloured and have crowded pale-yellow gills. The yellowish-white stipe is central and 9 cm tall; it is slightly bulbous, and enclosed into a volva. The yellowish-white ring is flared, ample, and membranous. The spores are 8.5–10 μm long and 6–6.5 μm wide, white, amyloid, and ellipsoid. The species is similar in appearance to A. flavoconia and A. flavipes.
Amanita augusta is a small tannish-brown mushroom with cap colors bright yellow to dark brown and various combinations of the two colors. The mushroom is often recognizable by the fragmented yellow remnants of the universal veil. This mushroom grows year-round in the Pacific Northwest but fruiting tends to occur in late fall to mid-winter. The fungus grows in an ectomycorrhizal relationship with hardwoods and conifers often in mixed woodlands.
Amanita flavorubens, also known as the yellow American blusher or the yellow American blushing amanita, is a species of the mushroom genus Amanita.
