설명 2 

Amanita verna, commonly known as the fool's mushroom, Destroying angel or the mushroom fool, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe in spring, A. verna associates with various deciduous and coniferous trees. The large fruiting bodies (i.e., the mushrooms) appear in summer and autumn; the caps, stipes and gills are all white in colour.

 

Description

The fool's mushroom (Amanita verna) also known as the spring destroying angel or death angel, is a close relative of Amanita phalloides, the death cap and a member of the mushroom genus Amanita. Amanita verna, like its close relative, belongs to the subfamily Phalloideae.

The fool's mushroom is pure white, all the way to the gills and the stem. This fungus, like all amanitas, has a volva. The fool's mushroom's cap is 5–10 centimetres wide, and is about the same height.

This mushroom's lamellae is free and white, and the volva is bag-like and large. Its annulus is white and membranous, and A. verna also does not react with potassium hydroxide solution, unlike its relative Amanita virosa. The mushroom's spores are smooth and elliptical.

 

Habitat and season

The mushroom lives in Europe. The fool's mushroom is known to grow in woodlands and hardwood forests.

As the fool's mushroom other name (spring destroying angel) suggests, this toxic amanita grows in spring.

Unlike various closely related poisonous amanitas, this mushroom is not known to occur in North America

Amanita virosa, commonly known as the European destroying angel, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe, A. virosa associates with various deciduous and coniferous trees. The large fruiting bodies (i.e., the mushrooms) appear in summer and autumn; the caps, stipes and gills are all white in colour.

 

Immature specimens of A. virosa resemble several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Along with its geographical namesakes, A. virosa is one of the most poisonous of all known poisonous mushrooms; its principal toxic constituent α-amanitin damages the liver and kidneys, often fatally. There are only a few known antidotes, one of which is a compound derived from milk thistle.[citation needed]

 

 

Its specific epithet virosa derived from the Latin adjective virōsus 'toxic'

 

 

Description

A. virosa first appears as a white egg-shaped object covered with a universal veil. As it grows, the mushroom breaks free, though there may be ragged patches of veil at the cap edges. The cap is initially conical with inturned edges, before becoming hemispherical and flattening with a diameter up to 12 cm. The cap often has a distinctive boss; it is able to be peeled and white, though the centre may be ivory in colour. The crowded free gills are white, as is the stipe and volva. The thin stipe is up to 15 cm tall, with a hanging grooved ring. The spore print is white and the spores egg-shaped conical and 7–10 μm long. They stain blue with iodine. The flesh is white, with a taste reminiscent of radishes, and turns bright yellow with sodium hydroxide.
