Amanita excelsa var. spissa is a variety of basidiomycete fungus of the genus Amanita . This large, grey to brown-capped fungus has a very variable appearance but is commonly encountered in coniferous and deciduous forests in Europe and North America. It is sometimes referred to by the common name grey spotted Amanita.

Description

The cap is around 10 cm in diameter when fully expanded, and is various shades of brown or brown/grey, sometimes washing off to buff. Younger specimens have grey veil remnants often in quite large; flat patches, but these are usually removed later by the weather. The mature stem is usually fairly long, and has a bulbous base which is without a discernible volva, having just several flaky ring zones instead. It is marked above the ring with vertical lines. The ring is large and white, and also has lines. The gills are crowded; white, and have a slight decurrent tooth. The flesh is white; smells of radish, and turns purple when H2SO4 is applied. [1]

Distribution and habitat

Amanita excelsa var. spissa occurs in Britain, Europe, and eastern North America in summer, and autumn. Growing with both broad leaved and coniferous trees. A. excelsa var. spissa is considered by some authors to be the more common variety of Amanita excelsa . [1]

Edibility

Pronounced edible by some, [2] but probably best avoided in case of confusion with A. pantherina .

<span class="mw-page-title-main">Blusher</span> Species of fungus

The blusher is the common name for several closely related species of the genus Amanita. A. rubescens, or the blushing amanita, is found in Europe and eastern North America, and A. novinupta, also known as the new bride blushing amanita, is found in western North America. Both their scientific and common names are derived from the propensity of their flesh to turn pink upon bruising or cutting.

<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 cap is gray or brownish, 5 to 10 centimetres in diameter, and has furrows around the edge that duplicate the gill pattern underneath. Unlike many other Amanita mushrooms, A. vaginata lacks a ring on the stem.

<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 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 regalis</i> Species of fungus

<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 ravenelii</i> Species of fungus

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

<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 excelsa</i> Species of fungus
