Amanita umbrinolutea, also known as the umber-zoned ringless amanita, is a species of the genus Amanita .
The cap of A. umbrinolutea is usually free of volval remnants, 4.5–9 centimetres (2–3+1⁄2 inches) wide, at first conico-paraboloid, then somewhat campanulate to convex and finally planar, umbonate, with a strongly striate margin (occupying around 25–35% of the cap's radius). [1] The cap is often dark in the center, then pale, then dark over the inner edges of the lamellae and on the ridges between the marginal striations; it can at other times be pallid in the center, but strongly zonate; the pigmentation intensity varies, with the center ranging from umber to grayish umber-brown to beige or pale grayish brown. The gills are free, crowded, off-white to sordid pale cream in mass, and up to 6 millimetres (1⁄4 in) broad; the short gills are truncate, vary in length, and are scattered and unevenly distributed. [1]
The stem is 11.5–18.5 cm (4+1⁄2–7+1⁄2 in) × 6–11 mm, pale cream to pale beige or isabella color or pale grayish brown, with a faint appressed zigzag girdles of fibrils, with a fleshy membranous sack-like volva at the base. The 3–4 cm (1–1+1⁄2 in) high volva is attached to the bottom 5 mm or so of the stipe. The spores measure 10.5–13.4 × 9.5–12.5 (1.05–1.34 x 0.95–1.25 cm) μm and are subglobose (infrequently either globose or broadly ellipsoid) and inamyloid. Clamps are absent from the bases of basidia.
A. umbrinolutea is widely distributed in Europe, with its range extending eastward at least to around northwestern Pakistan and North India. Known specimens have examined have all been found in association with conifers (including pine and spruce). [1]
Amanita fulva, commonly called the tawny grisette or the orange-brown ringless amanita, is a basidiomycete mushroom of the genus Amanita. It is found frequently in deciduous and coniferous forests of Europe, and possibly North America.
Amanita orientifulva, also known as the Asian orange-brown ringless amanita, is a species of agaric fungus that fruits singly or scattered from June to September.
Amanita persicina, commonly known as the peach-colored fly agaric, is a basidiomycete fungus of the genus Amanita with a peach-colored center. Until c. 2015, the fungus was believed to be a variety of A. muscaria.
Amanita vaginata, commonly known as the grisette or the grisette amanita, is an edible mushroom in the fungus family Amanitaceae. 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.
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.
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.
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.
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.
Amanita nehuta, also called Maori dust amanita, is a species of fungus in the family Amanitaceae.It has only a dark ring rather than a universal veil and white spores. Abundant in New Zealand, it can be found growing under Leptospermum and Nothofagus species.
Amanita atkinsoniana, also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. The fruit body is white to brownish, with caps up to 12.5 centimetres in diameter, and stems up to 20 cm long. The surface of the cap is covered with brownish conical warts.
Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 millimetres wide. The stems are up to 10 cm (4 in) tall, cream-coloured 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.
Amanita crocea, the saffron ringless amanita, is a species of Amanita widely distributed in Europe. It is not recommended for consumption due to its similarity to poisonous species of the genus.
Amanita albocreata, also called the ringless panther or the ringless panther amanita, is a species of fungus in the family Amanitaceae. It was discovered in 1944, by William Murrill. It is commonly found in the northeastern United States and parts of southeastern Canada. It normally grows between the rainy months of June and August.
