Eichleriella sp.

The fruit body is flat and appears on wood. The fertile surface is usually pale coloured (e.g. off-white, greyish, buff, straw) and smooth. There is a furry/hairy margin and that furriness/hairiness extends to the rear surface of the fruit body. Those hairs are often creamy or some shade of brown. In dry conditions the margins fold inwards so as to cover much, or all, of the fertile surface. When hydrated the fruit body is soft, certainly not jelly-like, but more like wax. 

The fruit bodies start as small, circular growths and initially you see little but the furriness. Left undisturbed the fruit body would expand radially, keeping that circular form. However, pressure from neighbouring fruit bodies may distort the growth or fruit bodies may merge so as to create irregular shapes.
