Amanita hygroscopia (/æməˈnaɪtə /ha͡ɪɡɹəskˈo͡ʊpi͡ə), also known as the pink-gilled destroying angel is a deadly poisonous fungus, one of many in the genus Amanita.

Taxonomy

The species was first described by William Chambers Coker in 1917.[1]

Description

The cap is Шаблон:Convert wide and hemispheric. The gills are adnate, crowded, medium broad, entire, white, unchanging.

The stem is about Шаблон:Convert, narrowing upward, smooth, glabrous, white, unchanging when bruised. The ring is fixed Шаблон:Convert from the top of the stem, very short, skirt-like, grooved by the gills above, white, persistent. The bulb is ovoid, white, Шаблон:Convert. The volva is neither appressed nor widely spreading, the edge is either 3-lobed or ragged.[2] The mushroom is odorless and tasteless.

Similar species

A. hygroscopia resembles several edible species, most notably Agaricus campestris.

Toxicity

The principal toxic constituent is α-Amanitin, an elective inhibitor of RNA polymerase II and III, which causes liver and kidney failure. 15% of those poisoned will die within 10 days and those who survive are at risk of lifelong, permanent liver damage.[3]

There is no antidote for amanitin poisoning; treatment is mainly supportive (gastric lavage, activated carbon, and fluid resuscitation).

Amatoxins, the class of toxins found in these mushrooms, are thermostable: they resist changes due to heat, so their toxic effects are not reduced by cooking.
