Tripe Fungus - Auricularia mesenterica

The thick fruitbodies are pale greyish-brown, and have a rubbery, cartilaginous texture.  Young specimens are pinkish, and initially form circular patches on the substrate.  These join up to form resupinate mats, eventually reflexing to shelf-like brackets, often in tiers.  The upperside is hairy or velvety, and usually zoned; the lower fertile surface or hymenium is veined and wrinkled and may have a whitish bloom. 

The reflexed brackets can look like a Stereum or curtain crust, but have a wrinkled and veined lower surface and rubbery texture
