Lichens fascinate me ; apparently some co-exist in a form of symbiosis with algae . On bare rocks the algae dissolve the surface and convert minerals into a foodstuff sufficient to sustain both organisms . How amazing is that ? With over 20,000 species globally , they colonise inhospitable areas from the Arctic to the Antarctic . Quite a success story !
I hate to disagree but I think that bench is horrible! Presumably not for sitting on. If my bench starts going like that, I'm getting the scrubbing brush out.

I don’t know about the nitrogen dioxide causing yellowing.
Not sure how quickly we can get some lichen growing by painting a wall with yoghurt though we have some already, nothing we could showcase.
