Bear's head fungus, hericium americanum:
An awesome find anytime, this mushroom is most often found growing on a stump or a log, but can be found growing out of woody debris in soil. A potent and valuable medicinal mushroom which is also delicious with a slightly seafood taste.
Closely related to the lion's mane mushroom, these 'pom-pom' mushrooms are among the easiest to identify, having no poisonous lookalikes beyond some corals which are reported to produce some gastrointestinal distress in some people.
Easy to tell the difference though, corals grow upwards out of the ground, hericium such as bear's head or lion's mane grow downwards generally from the side of a stump or log.
