Tremella mesenterica
A vivid orange-yellow, gelatinous bracket fungus that appears in winter on dead gorse and hardwood twigs. Despite appearances, it is a parasite on the mycelium of crust fungi in the wood, not on the wood itself. Shrivels in dry weather and reconstitutes in rain.
Conservation Status: LC
