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.

Taxonomy

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]

Description

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]

Distribution and habitat

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]

Toxicity

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]

<span class="mw-page-title-main">Edible mushroom</span> Edible fungi fruit bodies

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.

<i>Amanita</i> Genus of mushrooms including some very deadly species

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.

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.

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

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.

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

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.
