Peanut Butter Cup


The Peanut Butter Cup, Galiella rufa, is a common early summer mushroom in eastern North America. It's saprobic on hardwood sticks and logs and grows in the shape of a little cup (2-4 cm wide) with a densely hairy dark-brown exterior, and peanut-butter interior. If you tear it open, you will find beneath the interior surface gelatinous flesh.
