I really should have washed the van...

I just noticed this growing on the van we emigrated with seven years ago. It hasn't been used for years and it seems to be getting taken over by lichen!



I always thought lichen grew really slowly, but these seem to be making pretty good progress. There are some 'frondy' types, too, which I always thought were supposed to be an indicator of good air quality.



I think maybe I won't bother washing it for a few more years. It makes a good shed, anyway...

And I thought I was bad about getting around to washing the car... lol

I think lichen's very beautiful and I just found out it's a composite of fungus and algae, not a single organism. Cool!
It was all very well learning that the catastrophic late blight this year is a neither here-nor- there oomycete,
but the most damage I've seen lichen do is dyeng natural-wool jersies a disconcerting greenish-brown.
