The vermilion grisette, also known as pretty grisette or vermilion ''Amanita'' (''Amanita xanthocephala'') is a colourful mushroom of the genus ''Amanita''. However, although it is often referred to by the common name "grisette", it is not closely related to other edible species that carry this common name, such as ''Amanita vaginata'' and ''Amanita fulva''. It belongs to the same group of ''Amanita'' as ''A. muscaria'' and is reported to be toxic. It derives its specific epithet ''xanthocephala'' from the Greek ''xanthos''/ξανθοѕ "yellow" and ''kephale''/κεφαλη "head". It is a ringless mushroom with a yellowish- to reddish-orange cap up to 3–5 cm (1–2 in) in diameter, with deeper colour toward the centre, and paler similar-coloured warts. The gills and slim ringless stipe are pale yellow or white. The white volva has a neat outturned lip and is often bordered with orange or yellow. ''Amanita xanthocephala'' lives in an ectomycorrhizal relationship with ''Eucalyptus''. It is found in eucalypt forests in the southwest of Western Australia, as well as southeastern Australia from near Adelaide around to Southeast Queensland.〔 At one stage this fungus was known as ''Amanitopsis pulchella'', a small genus that all grisettes (ringless ''Amanita'' species) were placed in. However, this genus has been later sunk back into ''Amanita''. Unlike most ringless ''Amanita'', which are part of ''Amanita'' section ''Vaginatae'' (''A. vaginata'' and allies), ''A. xanthcephala'' belongs to ''Amanita'' section ''Amanita'' (''A. muscaria'' and allies). () There is one report of a person being quite ill after tasting a small piece of it in 1997. ==See also== *List of ''Amanita'' species 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amanita xanthocephala」の詳細全文を読む スポンサード リンク
