Amanita caojizong (formerly Amanita manginiana sensu W.F. Chiu) or Chiu's false death cap, is a mushroom of Amanitaceae found in East Asia and Mainland Southeast Asia.
It is known in Chinese as caojizong.[note 1]
Description
[edit]Overall, the mushroom is medium or big in size, occasionally even larger. It doesn't have a distinct odor.
As for the cap, the diameter is commonly ranged 5–15 cm, with the biggest seen being 20 cm. Its shape is plano-convex to flat, sometimes centrally umbonate. The color is ranged being brownish gray, brown, gray to dark gray. When broken, the flesh is white and doesn't change the color. The gills are white to cream-colored.
The stem is 9–15 cm long and 0.5–3 cm thick in diameter. White. Center soft or stuffed. It has a white annulus at the uppermost or almost uppermost position of the stem. It has a white volva.[1]
Taxonomy
[edit]This mushroom was first scientifically described by Wei-Fan Chiu in 1948 under the name of "Amanita manginiana".[2] Noticing that this mushroom has some morphological disparities from the protologue and type illustration of A. manginiana, Yang (1997) called this mushroom "Amanita manginiana sensu W.F. Chiu".[3] The mushroom was given an independent name Amanita caojizong in Cui et al. (2018).[1]
Habitat
[edit]It grows in forests of pines, broad-leaved trees or both Fagaceae and Pinaceae trees.[1]
It is found in China, South Korea, Japan and Thailand.[1]
Edibility
[edit]This mushroom is edible.[1] However, consumption is not recommended as this mushroom is visually similar to toxic Amanita species, such as Amanita pseudoporphyria.[1]
