Description

Some of the species' notable physical characteristics, however, distinguish it from the other members of the genus. For instance, the colors of the cap, darkening over the disk and the universal veil colored yellow to cream. The other characteristics of the other parts of its body are as follows:

Distribution and habitat

This rare species is normally found in mixed forests with oaks (mostly Quercus oaks) and conifers (mostly Pinaceae conifers). [1] It is considered native to eastern U.S. and southeastern Canada. [1]

Similar species

Amanita frostiana is similar to a range of species, like Amanita rubrovolvata , Amanita flavoconia , Amanita albocreata , Amanita muscaria var. muscaria or simply Amanita muscaria and Amanita subfrostiana .

Amanita rubrovolvata is slightly similar physically to this species. The fungus produces small- to medium-sized mushrooms, with reddish-orange caps. Roger Heim reported A. frostiana as occurring in Thailand, [7] but this was probably a misidentification of A. rubrovolvata.

Amanita subfrostiana , also referred to as 'False Frost's Amanita', has the same natural habitat as of A. frostiana, but is mostly distributed in southwestern China. [8] It does resemble A. frostiana but due to the different paleness of color in the cap of this species helps avoid misidentification.

The distinct and starkly white bulb (e.g., 17 x 15 mm) bears a white or yellow-white collar that is somewhat similar to the collar seen in the exannulate Amanita albocreata , [1] which is a species of the hardwood-hemlock (Tsuga) forest of the northeastern U.S. and southeastern Canada and of boreal forest at least as far north as the Island of Newfoundland.

The clamps present at bases of basidia of this species specially support the presumed relationship to Amanita muscaria var. muscaria or simply Amanita muscaria . [1] Amanita muscaria is a poisonous and psychoactive basidiomycete fungus, one of many in the genus Amanita.

Many misidentifications have taken place while recognizing Amanita flavoconia , one of the most common and widespread species of Amanita in eastern North America, due to various similar physical characteristics. It is mostly confused due to their microscopic features. [9]

Edibility

The species is considered inedible [10] and poisonous. [4] [11]

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

Amanita persicina, commonly known as the peach-colored fly agaric, is a basidiomycete fungus of the genus Amanita. This fungus was previously believed to be a variety of Amanita muscaria, but research has recently shown that Amanita persicina is best treated as a distinct species.

<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, Amanita flavoconia grows on the ground in broad-leaved and mixed forests, especially in mycorrhizal association with hemlock.

<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 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. The species is distributed in eastern North America, from Nova Scotia to Mexico, and may be found growing on the ground in deciduous forests, particularly those with oak, hickory and chestnut. Fruit bodies smell somewhat like bleaching powder, and their edibility is unknown, but possibly toxic.

<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 fruit bodies are found on the ground in mixed coniferous and deciduous forests of eastern North America south to Mexico, but are rare in western North America; the fungus has also been found in pine plantations in Colombia. The mushroom has a smooth white cap that can reach up to 10 cm (4 in) across, and a stipe, up to 14 cm (5.5 in) long by 1.8 cm (0.7 in) thick, that has a delicate 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 as immutable as was once thought.

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

Amanita jacksonii, also known as Jackson's slender amanita, is a species of fungus in the family Amanitaceae. It is a reddish-orange colored mushroom species extending from the Province of Quebec, Canada to at least the State of Hidalgo, Mexico. It was given its current name in 1984 by Canadian mycologist René Pomerleau. It can be identified by its yellow gills, large, white, sacklike volva, and bright orange or orange red cap, which has lined margins.

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

Amanita atkinsoniana, also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. It is found in the northeastern, southeastern, and southern United States as well as southern Canada, where it grows solitarily or in small groups on the ground in mixed woods. The fruit body is white to brownish, with caps that measure up to 12.5 cm (5 in) in diameter, and stems up to 20 cm long and 2.5 cm (1 in) thick. The surface of the cap is covered with reddish-brown to grayish-brown conical warts. The stem has a bulbous base covered with grayish-brown scales. The fruit bodies smell faintly like bleaching powder. Although not known to be poisonous, the mushroom is not recommended for consumption.

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

Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. First described scientifically by the Japanese mycologist S. Imai in 1939, it is widely distributed in eastern Asia. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 mm (0.26 in) wide. The stems are up to 100 mm (3.9 in) tall, cream 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. Neither edibility nor toxicity have been established for the fungus, but it is suspected to be associated with neurological anomalies. Several molecular studies have confirmed the mushroom's classification in the subgenus Amanita of the genus Amanita, along with closely related species such as A. muscaria.

<i>Saproamanita thiersii</i>

Saproamanita thiersii, commonly called Thiers' lepidella, is a North-American saprotrophic basidiomycete fungus in the genus Saproamanita. It is a white mushroom originally described from Texas but today found in nine states of North America. It was named after Harry Delbert Thiers. The cap of this small mushroom is white and convex, measuring 35–100 mm (1.4–3.9 in) and covered by volval remnants. It is sticky to the touch when wet. The gills are variable in length and number and are densely packed in some specimens and widely spaced in others. They are not attached to the stipe, which is 8–20 cm (3–8 in) long and about 1 cm (0.4 in) thick, with a white ring. The spores measure 7.8–9.8 by 7.3–9.0 µm and are roughly spherical in shape. The spore print is white.

<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.

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

Amanita albocreata, also called the ringless panther or the ringless panther amanita, is a species of fungus in the family Amanitaceae. 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.

<i>Amanita muscaria <span style="font-style:normal;">var.</span> formosa</i>

Amanita muscaria var. formosa, known as the yellow orange fly agaric, is a hallucinogenic and poisonous basidiomycete fungus of the genus Amanita. This variety, which can sometimes be distinguished from most other A. muscaria by its yellow cap, is a European taxon, although several North American field guides have referred A. muscaria var. guessowii to this name. American mycologist Harry D. Thiers described a yellow-capped taxon that he called var. formosa from the United States, but it is not the same as the European variety.

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

Amanita parcivolvata also known as ringless false fly amanita, is a fungus that produces fruit bodies that vaguely resemble those of Amanita muscaria. It is differentiated, however, by its lack of an annulus, by the volval deposits on its stipe/base, and by its pileal striations. It occasionally lacks a stipe bulb entirely, instead just tapering to a point in the ground with powdery volval deposits on its surface. It ranges from 3–12 cm (1.2–4.7 in) in length and is occasional to common in the Southeastern United States, occurring primarily in Quercus forests though it has been observed in forests with a mix of conifers and oaks.

<i>Amanita crenulata</i> Toxic species of mushroom

Amanita crenulata, also known as the poison champagne amanita, is a species of fungus that is very common in the Northeast United States.
