Oudmansiella mucida aka Porcelain Fungus

edible.

 

specific to beech wood. It appears in autumn on dead trunks and on fallen branches, and occasionally it also grows on dead branches high up in living trees.

 

Provided that the skin is thoroughly washed to remove the mucus (or peeled from the caps), these mushrooms are edible, although their slimy covering is probably enough to put most people off. Only larger caps are worth collecting, because the flesh is thin and insubstantial.
