Crust fungus

Description:

Bright yellow patches of crusty fungus growing on a decaying tree branch. The surface appeared to have tiny finger-like projections but these were barely discernable to the naked eye. The patches appeared paler along the margins

Habitat:

Dry schlerophyll forest. This was spotted on wood beside a creek - the area was still damp from recent rains.

Notes:

Any help with an ID will be greatly appreciated.
