Amanita 'egg'

''Amanita vaginata'', commonly known as the grisette, is an edible mushroom in the Amanitaceae family of fungi. Unlike many other ''Amanita'' mushrooms, ''A. vaginata'' lacks a ring on the stem. The cap is gray or brownish, 5 to 10 centimetres in diameter, and has furrows around the edge that duplicate the gill pattern underneath. It has a widespread distribution in North America, and is thought to be part of a species complex that includes other similar-looking Amanitas.
