Mostly dull.
And my favourite at this time of year: Exidia recisa - Black Witches Butter.
The basic form is a vaguely cup-shaped disc with a defined edge:
The fruitbodies have a tendency to absorb water, especially in very damp locations, such as this willow branch overhanging a ditch. This causes them to inflate and become transparent.
In some individuals, this inflation produces bizarre glittering pendants.
They can create the impression of gems hanging from branches.
