Amanita magniverrucata, commonly known as the pine cone amanita,[2][3] or great pine jewel, is a species of agaric mushroom in the family Amanitaceae.
Taxonomy
[edit]It was first described scientifically by American mycologists Harry Delbert Thiers and Joseph Ammirati in 1982.[4]
Description
[edit]It is a whitish mushroom. The cap is typically up to 20 centimetres (8 in) wide with dark scales. The gills are very close. The stem is about 7–13 cm (3–5 in) long.[2] The smell is mild but unpleasant in age and the spore print is white.[5] While its edibility is unknown, it may be poisonous,[6] as are other Amanitas in the same subgroup.[2]
Although there are a number of lookalike species, its large warts are a distinguishing feature.[2]
