Amanita xanthocephala, known as the vermilion grisette, pretty grisette or vermilion amanita is a colourful mushroom of the genus Amanita . It is found in south Australia in association with Eucalyptus and may be toxic to humans.
At one stage this fungus was known as A. pulchella, in a small genus that all grisettes (ringless Amanita species) were placed in. This genus later sunk back into Amanita. Unlike most ringless Amanita, which are part of Amanita section Vaginatae (e.g. A. vaginata ), A. xanthcephala belongs to Amanita section Amanita (e.g. A. muscaria ). [1]
It derives its specific epithet xanthocephala from the Greek xanthos/ξανθοѕ "yellow" and kephale/κεφαλη "head". [2]
It is a ringless mushroom with a yellowish- to reddish-orange cap up to 3–5 centimetres (1–2 inches) in diameter, with deeper colour toward the centre, and paler similar-coloured warts. The gills and slim ringless stipe are pale yellow or white. The white volva has a neat outturned lip and is often bordered with orange or yellow. [3]
A. xanthocephala is distributed in southwest Western Australia, as well as southeastern Australia from around Adelaide to Southeast Queensland. It is particularly found in eucalypt forests, as it has an ectomycorrhizal relationship with Eucalyptus . [3]
Like its relative A. muscaria, it is reported to be toxic.[ citation needed ] There is one report of a person being quite ill after tasting a small piece of it in 1997. [4]
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.
Edible mushrooms are the fleshy fruit bodies of several species of macrofungi. Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "choice". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor.
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.
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus.
Amanita fulva, commonly called the tawny grisette or the orange-brown ringless amanita, is a basidiomycete mushroom of the genus Amanita. It is found frequently in deciduous and coniferous forests of Europe, and possibly North America.
The Amanitaceae is a family of mushroom-forming fungi. Amanita Pers. is one of the most speciose and best-known fungal genera. The family, also commonly called the amanita family, is in order Agaricales, the gilled mushrooms. The family consists primarily of the large genus Amanita, but also includes the smaller genera Amarrendia, Catatrama, Limacella, Limacellopsis, Saproamanita, Torrendia and Zhuliangomyces. Both Amarrendia and Torrendia are considered to be synonymous with Amanita but appear quite different because they are secotioid.
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.
The Fungi of Australia form an enormous and phenomenally diverse group, a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems.
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 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 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 crocea, the saffron ringless amanita, is a species of Amanita widely distributed in Europe. It is not recommended for consumption due to its similarity to poisonous species of the genus.
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.
Amanita frostiana, also known as Frost's amanita, is a small yellow-to-red fungus found in eastern North America.
Amanita parcivolvata also known as ringless false fly amanita, is a fungus that produces fruit bodies ranging from 3–12 centimetres in width and height.
Amanita pachycolea, commonly known as the western grisette or the Stuntz's great ringless amanita, is a species of agaric fungus in the family Amanitaceae.
Amanita yema is a species of fungus in the genus Amanita, family Amanitaceae. The fungi can be identified by its pileus color of a red center that gradually fades into a yellow-hued edge. Growing only in forest outskirts in Mexico, the fungus is a critical member of the plant biome as it is a mycorrhizal fungi.
