Amanita virgineoides, known as the false virgin's lepidella, is a species of fungus in the genus Amanita .

Description

The basidiocarps are medium-sized to large. The cap is 7–15 centimetres (3–6 inches) wide, convex to applanate, sometimes concave, and white, covered with white, conical to pyramid volval remnants 1–3 millimetres (11618 in) high and wide. The cap margin is smooth and appendiculate, and the context is white and unchanging. [1]

The gills are free to subfree and white to cream; the short gills are attenuate.

The stipe is 10–20 cm (4–8 in) × 1.5–3 cm (12–1 in), subcylindric or slightly attenuate upwards, white, covered with white floccose squamules; the context is white; the stipe's basal bulb is 3–4 cm (1–1+12 in) wide, ventricose, ovoid to subglobose, with its upper part covered with white, verrucose to granular volval remnants. The annulus is white; its upper surface bears fine, radial striations; and its lower surface, verrucose to conical warts. The annulus is often broken during expansion of the cap.

The spores measure 8–10 × 6–7.5 µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are common at bases of basidia.

<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.

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

Amanita cokeri, commonly known as Coker's amanita and solitary lepidella, is a poisonous mushroom in the family Amanitaceae. First described as Lepidella cokeri in 1928, it was transferred to the genus Amanita in 1940.

<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 echinocephala</i> Species of fungus

Amanita echinocephala is a large, whitish or ivory-coloured mushroom with a characteristic spiny, or warty-looking cap. A. solitaria is a synonym and opinions are divided as to which name takes precedence. It lives on chalky soils with beech trees, and appears earlier than most mushrooms of similar size in southern England. It frequently occurs singly or in small groups, resulting in it being referred to as the solitary amanita or, more specifically, European solitary lepidella. It is very drought-tolerant.

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

Amanita abrupta, commonly known as the American abrupt-bulbed amanita or the American abrupt-bulbed lepidella, is a possibly toxic species of fungus in the family Amanitaceae. Named for the characteristic shape of its fruit bodies, this white Amanita has a slender stem, a cap covered with conical white warts, and an "abruptly enlarged" swollen base. This terrestrial species grows in mixed woods in eastern North America and eastern Asia, where it is thought to exist in a mycorrhizal relationship with a variety of both coniferous and deciduous tree species.

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

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.

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

Amanita onusta, commonly known as the loaded Lepidella, the gunpowder Lepidella or the gunpowder amanita, is a species of fungus in the mushroom family Amanitaceae. It is characterized by its small to medium-sized fruit bodies that have white to pale gray caps crowded with roughly conical, pyramidal, or irregular gray warts. The stipe is whitish-gray with woolly or wart-like veil remnants, and at the base is a spindle- or turnip-shaped base that is rooted somewhat deeply in the soil.

<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 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.

The mushrooms have a unique chlorine like odor.

<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.
