Something thriving on the side of disused lead blast furnaces. There was very little there when I was a child - all N.E. facing walls now getting covered. Possibly plant, has filaments approx 1.5mm long feels like velvet to touch (but I didn't harm it rest assured!)To describe colour as bright almost fluorescent orange is an understatment. Didn't not look like it undertook photosynthesises? Poss chem autotroph? Habitat = heavy lead contamination up until ~ 1918.
