grisette

Description:

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 (2.0 to 3.9 in) 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

Habitat:

A mycorrhizal species, Amanita vaginata grows singly or numerous in both coniferous and hardwood forests. It has also been noted to occur frequently in grassy areas at the edge of forests, unkempt lawns, and suburban area where the ground has been recently disturbed. A widely distributed and common species, it fruits from the spring to the fall

Notes:

The cap is 3 to 10 centimetres (1.2 to 3.9 in) in diameter and gray to grayish-brown in color; initially the cap is oval, then as it matures it becomes progressively conical, convex, and eventually flattened, sometimes with a small umbo (a rounded elevation in the center of the cap).[
