Amanita altipes, also called the yellow long-stem amanita, is a species of agaric fungus found in coniferous woodlands in southwestern China.

Description

Amanita altipes is a small to medium-sized agaric with a distinctively yellowish overall coloration. The cap has a diameter of up to 9 centimetres (3+12 inches) and is yellow, often brownish towards the centre. The appearance of the cap may be convex to plano-convex. The volva is present as felty, floccose patches, 2–5 millimetres (116316 in) wide and up to 1 mm thick. Unlike many of its relatives (e.g. A. pantherina ), the remnants of the universal veil do not usually persist on the cap, being easily washed away by rain. [1] The yellowish stipe is relatively long (up to 16 cm or 6+12 in), and usually tapers upwards. There is a large, persistent ring. The gills are free, crowded, and white to cream-colored to yellowish. The short gills (lamellulae) are truncate, numerous, and are evenly distributed. The spores measure 8.0–10.0 by 7.5–9.5  µm and are spherical (or nearly so) and inamyloid. There are no clamps present at the bases of basidia. The flesh is white in color and inedible.

Etymology

The specific epithet altipes means "referring to the long stipe", and it suits the species as it has a longer stipe compared to its relatives. [2]

Distribution and habitat

This species is widespread in southwestern China, mostly in Yunnan. [3] It has also been reported that it is found in eastern Himalayas and adjacent regions. [2] It grows on soil in coniferous ( Abies , Picea ) and broadleaved ( Betula , Quercus , Salix ) woodland in southwestern China up to an altitude of 4,000 metres (13,000 feet). [4]

<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.

Amanita parvipantherina, also known as the Asian small panther amanita, is a Chinese species of agaric which fruits in July and August. It has a brown cap up to 6 centimetres wide covered with whitish remnants of the universal veil. The stem is up to 9 cm tall. The similar A. pantherina is usually larger and less fragile, with fainter striations around the cap margin.

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

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.

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

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.

<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.

<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.
