Small brown cup fungus with brittle flesh. They were about 2 cm wide, but there was a larger one nearby that was at least 3 cm wide. They could have been growing on buried wood, but I’m not sure.
Habitat: Growing in moss along a hiking trail in a deciduous forest

A saprobic species, the fungus produces brownish, cup-shaped fruit bodies that grow singly or in clusters on either soil or well-rotted wood. It is found in Europe, North America, and Iceland, where it fruits in the spring.
