Amanita constricta

Amanita constricta

Amanita constricta is a close relative of A. vaginata, A. pachycolea, and A. protecta. Commonly known as "grisettes," members of this group have greyish to brown caps, lack an annulus, possess inamyloid spores, and have a universal veil that tends to bruise ochre or reddish-brown. Amanita constricta is distinguished from the above by a distinctive, membranous volva. Unlike the typical saccate volva which is attached only at the stipe base and then expands outward to form a cup, the volva of Amanita constricta is fused to the stipe except for a flaring margin.
