Also known as: Hedgehog mushroom, Yellow toothed fungus
This mushroom is distinctive for the spines, or teeth, that hang down from the underside of its cap. It can be found on forest floors singly or in groups. In spite of the name, sweet tooth, it has a slightly spicy bite and bitter aftertaste. This wild mushroom needs to be cooked before it is truly edible, and only young, parasite-free mushrooms should be harvested.
