Scientific name: Hericium americanum
Average size: 6 to 7¾ inches long
Can be found: On living and dead deciduous trees
Edible: YES

In Michigan, this mushroom can be found in undisturbed forests. It grows directly from dead trees, stumps, and even living trees. While most recorded specimens were discovered on deciduous trees, others have been found on evergreen trees.

The mushrooms have no circular caps like other mushrooms do. Instead, they grow in a linear pattern similar to a tree branch. Most average between 6 to 7¾ inches long.
On the ‘branch’ are hundreds of tiny frondlike spines. The full effect was similar enough to appear like the jawbone of a bear, which is how the mushroom got its name.
