Yellow Brain Fungus (Tremella mesenterica)
This one has the wonderful name of the Yellow Brain Fungus and it is certainly yellow! It starts lemon yellow, becomes egg yoke coloured before drying orange. In its early stages it gelatinous, watery and translucent but it becomes brittle when dry.
It is found on dead branches of Ash and Gorse and so is quite abundant on the heaths of Purbeck.
It is not edible, but then I didn't fancy it anyway!
