Poisonous mushrooms always have an annulus and volva.

Question

Quizplus · Accepted Answer

This statement is false. While some poisonous mushrooms may have an annulus (a ring on the stem) or volva (a cup-like structure at the base of the stem), not all of them do. It's important to note that relying on these characteristics alone is not a safe way to identify mushrooms as edible or poisonous. Other features such as cap color, gill structure, and spore print should also be considered, and when in doubt, it's best to leave mushroom identification to experts.
